Guest shutdown problems
by Christian Axelsson 02 Apr '09

02 Apr '09

Hello I have a problem shutting down xen guests. Using xm shutdown guests get shut down but gets stuck in state '---s-d' or sometimes '------'. When trying to clone a domain when in this state (my original purpose of the whole operation) I'll get the error: [root@hydra virtinst--devel]# ./virt-clone -o minimal -n new_img -f /var/lib/xen/images/new_img.img ERROR: virDomainGetXMLDesc() failed failed Xen syscall xenDaemonDomainDumpXMLByID failed to find this domain -490299505 The same errors occurs when for example trying to attach to the console using virsh. I have tried to use 'xm destroy' to kill the guest the hard way but it has no effect - the state remains unchanged. I have also tried this on a few different guest installations with the same result. A thing worth noting is that the output from 'xm list --long' differs, I've attached the out put pre boot, after boot and after shutdown. Note how all the devices in the guests are missing after shutdown. Both the hosts and the guests are fedora 8 installations.

Cannot start HVM DomU
by Robert Locke 04 Jul '08

04 Jul '08

This has newly started, so I am presuming that it is perhaps related to some recently updated package on F8 in say the last week or so. I have a WindowsXP DomU that when I try to start from virt-manager gives the following error: Error starting domain: virDomainCreate() failed POST operation failed: (xend.err 'int argument required') Details shows: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 472, in run_domain vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 379, in startup self.vm.create() File "/usr/lib/python2.5/site-packages/libvirt.py", line 240, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: virDomainCreate() failed POST operation failed: (xend.err 'int argument required') I have no idea what other information to supply or where to particularly find it since this has generally "just worked" for the occasional running of a Windows instance that I have needed for the last several months. Thanks for any help, --Rob

Custom bridge script; upgrade from Fedora 6 to Fedora 8
by Ask Bjørn Hansen 07 May '08

07 May '08

Hi, Since upgrading from Fedora 6 to Fedora 8 my custom bridge script stopped working. I need to have both eth0 and eth1 bridged into each XM. My xen machines are just defined in old-style /etc/xen/foo configuration files, like vif = [ 'mac=00:16:3e:42:08:1d, bridge=xenbr0', 'mac=00:16:3e: 42:08:1e, bridge=xenbr1' ] I've changed that to vif = [ 'mac=00:16:3e:42:08:1d, bridge=eth0', 'mac=00:16:3e:42:08:1e, bridge=eth1' ] but when I do a "xm create foo" I still end up with the new interfaces on the wrong bridge! # brctl show bridge name bridge id STP enabled interfaces eth0 8000.0030488c8a26 no peth0 eth1 8000.0030488c8a27 no peth1 xenbr0 8000.feffffffffff no vif1.0 xenbr1 8000.feffffffffff no vif1.1 If I manually move the vifX.X interfaces to the eth0/eth1 bridges then everything works. This is my custom bridge script: #!/bin/sh dir=$(dirname "$0") "$dir/network-bridge" "$@" netdev=eth1 bridge=eth1 "$dir/network-bridge" "$@" netdev=eth0 bridge=eth0 Any ideas? - ask -- http://develooper.com/ - http://askask.com/

Guest boots OK with ATA disk (hdX) but not SCSI (sdX).
by Friedrich Clausen 06 May '08

06 May '08

Hi All, (please feel free to refer me to the official Xen list if need be) I am still using the same dom0 as outlined in : https://www.redhat.com/archives/fedora-xen/2008-March/msg00006.html I can successfully boot a domU using /dev/hda1 as rootfs but when I boot using a scsi device it is unable to find its rootfs. I created an initrd, preloading the sd_mod, in the hopes that that will fix it. The initrd was created like so: # mkinitrd -v --preload=sd_mod --preload=xenblk --with=xennet --with=xenblktap --with=xenbus_be /tmp/test `uname -r` # cp /tmp/test /boot/initrd-2.6.21.7-2.fc8xen.img And the config of the guest is: kernel = "/boot/vmlinuz-2.6.21.7-2.fc8xen" ramdisk = "/boot/initrd-2.6.21.7-2.fc8xen.img" extra = "ro enforcing=0" root = "/dev/sda1" memory = 256 name = "centos.5-1.64" vif = [ '' ] disk = ['phy:VolGroup00/LogVol00,sda1,w'] But is fails to boot, here are some possibly relevant messages with the complete output at the end of this email : Creating /dev Creating initial device nodes Setting up hotplug.

I'm having trouble getting Xen up on Fedora 6. Following the instructions at http://fedoraproject.org/wiki/FedoraXenQuickstartFC6 , I've got xend running, but haven't gotten a viable image running. I tried (per the above) virt-manager. I guessed that http://download.fedora.redhat.com/pub/fedora/linux/core/6/x86_64/os/ was a suitable install tree, but when the installer (Anaconda, I guess) gets to some point (it varies with each attempt) it stalls, sometimes complaining about not getting a file. I also tried xm, but haven't figured out how to deal with the error: Cannot open root device "sda1" Virsh throws a different error: Domain not found: xenUnifiedDomainLookupByName I'm befuddled by having tried several different sources, each of which said "it's soooo easy", but failing to provide sufficient information to get me past these issues, so I'd be grateful if someone could point me to instructions geared to the meanest understanding.

How to add a PCI-Card to a DomU?
by Franz Von Hahn 29 Mar '08

29 Mar '08

Hello list! I know that there is some documentation about how to add a PCI-Card to a DomU using pciback and co. My problem is, that I'm really stuck and don't know where to start. Normally I create my DomUs with virt-install, following the instructions and later I get a .sxp-Configfile and an Imagefile. Works perfecty. But how in the world do I now add the PCI-Card to that config.sxp? Do I have to reinstall the DomU to do that? I'm using Fedora 8 with the latest updates. Thanks in advance, yours Franz v.

RHEL5 - Xend will not start after software upgrade
by Ubaidul Khan 25 Mar '08

Hello, Recently I ran yum update on a RHEL5 x86_64 machine and as part of the update, the following packages were installed: Updated: xen-libs-3.0.3-41.el5.x86_64 Updated: xen-libs-3.0.3-41.el5.i386 Installed: kernel-xen-2.6.18-53.1.14.el5.x86_64 Updated: xen-3.0.3-41.el5.x86_64 After the update, I rebooted the machine. Now, I cannot get xend to start: [root@saleen xen]# /etc/init.d/xend start Starting xend: [ OK ] [root@saleen xen]# ps -ef | grep xend root 4080 1 0 11:27 ? 00:00:00 python /usr/sbin/xend start root 4081 4080 0 11:27 ? 00:00:00 python /usr/sbin/xend start root 4264 3109 0 11:45 pts/1 00:00:00 grep xend [root@saleen log]# tail -f /var/log/xen/xend.log self.obj = klassobj() File "/usr/lib64/python2.4/site-packages/xen/xend/server/SrvDomainDir.py", line 39, in __init__ self.xd = XendDomain.instance() File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomain.py", line 655, in instance inst.init() File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomain.py", line 76, in init self._add_domain( File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomain.py", line 139, in xen_domains domlist = xc.domain_getinfo() Error: (13, 'Permission denied') I googled around, but I can't find anything useful. Some people mentioned they rolled back to the previous version of the kernel-xen, xend, xen-libs. I would like to find the reasons behind the problem before rolling back. Any assistance is greatly appreciated. Thanks _________________________________________________________________ In a rush?

Libvirt and xenstore - glitches on migrate
by Jim Klein 25 Mar '08

25 Mar '08

Nothing major, but when migrating with the current Red Hat xen bits and libvirt on F8 and RHEL, libvirt and virt-manager have all sorts of trouble (though the migrate works fine.) Example below is two laptops, the first with and NFS share of /var/lib/xen/images and the second attached to that share. On a migrate, source console kicks out out of memory errors on xenstore, and virt-manager status for the machine being migrated oscillates between "Running" and "Shutoff." No errors on the target machine. Console errors are listed below: xm migrate -l rhel4 turion64 libvir: error : invalid argument in __virGetDomain libvir: Xen Store error : out of memory libvir: error : invalid argument in __virGetDomain libvir: Xen Store error : out of memory libvir: error : invalid argument in __virGetDomain libvir: Xen Store error : out of memory libvir: error : invalid argument in __virGetDomain libvir: Xen Store error : out of memory libvir: error : invalid argument in __virGetDomain libvir: Xen Store error : out of memory libvir: Xen Daemon error : internal error domain information incomplete, missing name Nothing abnormal in xend.log or xend-debug.log, and the migrate works fine, just general ugliness in the interface (which is a bummer if you are doing a demo in front of an audience.)

newbie question to increase the size of "guest OS"...
by Dharmesh Kamdar 25 Mar '08

25 Mar '08

Hi, I've installed Fedora 8 as a guest OS on Fedora-7+XEN. The host info: $> uname -a Linux hojo 2.6.21-7.fc7xen #1 SMP Tue Feb 12 12:32:24 EST 2008 i686 athlon i386 GNU/Linux CPU: mobile AMD Athlon(tm) XP-M 1400+ RAM: 1GB ARCHITECTURE: x86 (32 bit) While creating the guest, I specified the storage as /var/lib/xen/images/f8_xen.img (of about 7 GB). Unfortunately the guest OS is running out of storage space and I want to add more storage to it (file system based, no LVM or partition etc). I did manage to increase the size of the image file via "dd" with dd as follows: dd if=/dev/zero of=/var/lib/xen/images/F8_XEN.img bs=2M seek=4096 conv=notrunc count=2048 2048+0 records in 2048+0 records out 4294967296 bytes (4.3 GB) copied, 124.617 s, 34.5 MB/s [root@hojo images]# [root@hojo images]# ls -ltr total 12398420 -rwxr-xr-x 1 root root 12884901888 2008-03-20 19:30 F8_XEN.img [root@hojo images]# Now, I want to add some more storage space to the guest OS. So how do I do it ? Will appreciate if someone can provide some pointers. Thanks, kamdard. ____________________________________________________________________________________ Looking for last minute shopping deals? Find them fast with Yahoo!

no Virtualization support for creating VM's on PE840‏
by Odi 25 Mar '08

25 Mar '08

what it is is that i recently purchased a Dell PowerEdge 840 after carefully selecting the specs i required, on its arrival i noticed that the BIOS does not support virtualization, as a result of this on successfully installing Xen vm on Open Suse 10.2 which creates the vm kernel and i try to start the vm i get the error message: 'Cannot start the virtual machine' then it goes on to say : command: /usr/sbin/xm create /etc/xen/vm/vm1 return Error: (22, 'Invalid argument') Using config file "/etc/xen/vm/vm1". when i prompt for more details i get: 'Error: HVM guest support is unavailable: is VT/AMD-v supported by your CPU and enabled in your BIOS' i have had a word with dell support who confirmed that the that the BIOS does not support virtualization for now and that that option in the bios is defaultly set to disable and that the most recent release of my BIOS software doesn't list this in the menu for me to toggle that option, and that maybe a future release of the BIOS software will have accessibilty to this option. I was adviced by the Dell Engineer to come this site and seek for help on this site. does anyone know what i can do to get around this problem please. i was told by the Dell engineer to run a cat command on the cpuinfo file to see if the flag will reflect xt or vt, i did this and the i got the following: odi@PE840Srv:/proc> cat cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU X3210 @ 2.13GHz stepping : 11 cpu MHz : 2133.600 cache size : 4096 KB physical id : 0 siblings : 4 core id : 0 cpu cores : 4 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc pni monitor ds_cpl vmx est tm2 cx16 xtpr lahf_lm bogomips : 4269.91 i badly need to create virtual machines on this server, its got 750 GB HDD (mirroring support) and 8GB of RAM, i selected all this with virtualization in mind obviously. any assistance will be greatly appreciated.

usb tablet support?
by Tom Horsley 20 Mar '08

20 Mar '08

I'm having a heck of a time discovering if I can actually make the mouse behave via usb tablet support or not. I've added usb=1 and usbdevice='tablet' to my fedora 8 HVM config file, but the mouse seems to act exactly the same way (however the qemu tablet device does show up in the /proc input device description, so it is getting defined). I suspect I need to do something to explicitly fix the xorg.conf file to use the evdev driver (or whatever it is called) and absolute cursor positioning, but I am having a heck of a time find any example xorg.conf file to try. Is it actually supposed to be possible to make this work these days? Anyone have a working xorg.conf from a fedora 8 HVM that demonstrates correct mouse tracking in the vnc console?

Console Not Configured For Guest
by Keith Mitchell 14 Mar '08

14 Mar '08

Hello- I have a xen xen-3.1.2-2.fc8 vm created using Virtual Machine Manager 0.5.3-1 running on Fedora Core 8 Kernel 2.6.21.7-2.fc8xen. The xen vm is using qemu-dm x64 (hvm). Here is my problem: When I use the Virtual Machine Console to connect to the VM created with the VMM using the .sxp file as its base, the console is able to connect and everything runs fine. When I attempt to bring up the same VM, using a normal xen python config using the same parameters as the sxp file, I get the error from the VMM "Console Not Configured For Guest". I have another VM on the same machine that is paravirtualized and I do not have this problem. I would like to have all my VM's using a common config format for ease of editing, and I'd like to use the xen python format as it has the best documentation. Any suggestions as to what I might look at to try and solve the problem? NOTE: I have examined the qemu.log files, and the only error I can see thrown is "xs_read(): vncpasswd get error." However, that error comes up when the VM is able to connect as well. Keith Mitchell CTO Productivity Associates, Inc. keithm(a)gotopai.com

2.6.21.7-2.fc8xen kernel with X11
by Jonathan Giles 11 Mar '08

11 Mar '08

After trying to resolve this problem on my own, perusing google etc. for 2 weeks, I could use some help figuring out why I can't start X11 when booting 2.6.21.7-2.fc8xen on my desktop. Booting 2.6.23.1-42.fc8 and running X11 works fine. I apologize if this is not the right place for this problem, and understand if you think it should be posted elsewhere. Just let me know and I will post it to the email list you think I should be posting to. logs etc. are truncated. I hope that's okay, I just didn't want to waste people's time. lspci out gives: 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35 Express DRAM Controller (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 02) 00:02.1 Display controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 02) /var/log/Xorg.setup.log Build Date: 17 October 2007 Build ID: xorg-x11-server 1.3.0.0-33.fc8 (EE) GARTInit: Unable to open /dev/agpgart (No such file or directory) EE) intel(0): Internal Error: maxCacheLines < 0 in i830_allocate_2d_memory() (EE) intel(0): Failed to allocate framebuffer.

After upgrade F7 to F8 vnc console no longer accessible {Scanned}
by Christian Exner 10 Mar '08

10 Mar '08

Hey list, after i upgraded my f7 xen host to f8 there is no way to access my vm's by vnc protocol (from Win workstation with UltraVNC Viewer). Something pops up and hide so quickly there is no chance to see what it is. virt-viewer also does not work. It seems that on f8 the "vnc-server" xen-vncfb has changed to qemu-dm. Can somebody tell me a location for good qemu-dm documentation? Is there a way to get debug output from qemu-dm? Any hint's are welcome. ThX a lot...

Plans for paravirt_ops kernel-xen
by Mark McLoughlin 09 Mar '08

09 Mar '08

Hi, Fedora's Xen hackers have been working hard towards switching our kernel-xen package from a forward-ported Xensource kernel tree to a state-of-the-art upstream, paravirt_ops based, kernel in Fedora 9 as described here: http://fedoraproject.org/wiki/Features/XenPvops http://www.redhat.com/archives/fedora-xen/2007-November/msg00106.html Some great progress has been made, and tomorrow's rawhide will have a kernel-xen update with: + A very recent 2.6.25-rc4 base + Xen paravirt_ops DomU from upstream + x86_64 Xen paravirt_ops DomU support + Paravirt framebuffer However, although the Dom0 paravirt_ops work is well advanced at this point, we still don't have backend drivers or x86_64 Dom0 working. With the feature freeze looming next week, we have make the difficult decision to focus the Fedora 9 efforts on DomU and postpone the inclusion of paravirt_ops Dom0 support. The alternative course of action was to keep shipping the 2.6.21.7 based kernel-xen in Fedora 9, but we have ruled this out as a supportable option. This kernel is almost a year old now and we cannot expect Fedora hackers to keep the distribution working on such an old kernel. Examples of the kind of issues we see cropping up are: 1) Broken installs due to old squashfs: https://bugzilla.redhat.com/431109 2) Broken SELinux due to old SELinux: https://bugzilla.redhat.com/436173 3) Broken networking due to old netlink: https://bugzilla.redhat.com/431179 We feel that making significant investment across the distribution to keep this old kernel working for the sake of Dom0 support would be wasting effort on a dead codebase. Work will continue apace on the Dom0 paravirt_ops effort for Fedora 10 and we hope to introduce the first build to rawhide soon after Fedora 9 been branched. This first build should include backend drivers and x86_64 support. If all goes well with the Dom0 support in Fedora 10 rawhide, we may well pull it into Fedora 9 as a post-GA update. So, in summary: 1) Try out the F9 rawhide/beta paravirt_ops kernel-xen in your DomUs 2) Keep your Dom0 on Fedora 8 for now 3) If you want to help out with Dom0 paravirt_ops testing, then be ready to jump onto Fedora 10 rawhide Thanks, Mark.

Hi All, Is it possible to auto start domU's listed in /etc/xen/auto in a particular order? I imagine it is, but my reading comprehension or my searching skills suck, because I can't find anything about this.

virbr0 comes from where?
by Tom Horsley 04 Mar '08

04 Mar '08

Actually I'm on centos, but I figure it probably does things similar to fedora. On centos I see a virbr0 bridge that gets created and used in clients where I pick virtual network. I've been trying to understand Xen networking, and since this virbr0 on centos is doing exactly what I tried unsuccessfully to do on a debian xen 3.2 system, I thought I'd look and see how it works. Easy to say, hard to do :-). I can't find any place that creates the virbr0 bridge. I don't see an ifcfg file to create it at boot time, and I just replaced the brctl command with a shell script to log all info about brctl calls, then invoke the original brctl, and no brctl command is ever issued to create virbr0! Where do it come from?

no guest configuration file in /etc/xen
by Akl Spec 04 Mar '08

04 Mar '08

Hi All, I am newbie to Xen. I installed xen-3.1.0-13.fc8 on fc8 and configured two fedora guest domains, one with virt-manager and the other with virt-installer. Both the virtual servers are up and i can boot them successfully, but both the installation didn't create the guest configuration file in /etc/xen directory(docs says configuration file will be created here). Can anybody please help me to find out those files?? Thanks in advance. AKL --------------------------------- Looking for last minute shopping deals? Find them fast with Yahoo! Search.
