treating logical volumes as physical drives
by Justin Wickett 09 Jan '07

09 Jan '07

I would like to use a logical volume as a "physical" drive on which I can install a fedora operating system. As of now, when I run xenguest- installer, it treats the install location that I specified ( which is an unformatted logical volume that I had just created ) as a physical drive (named "xvda") and allows me to perform a basic install on it. When I look at that logical volume, it comes up as a "foreign" device, because it contains a /boot directory, and a volume group consisting of a / directory and a swap directory. I was wondering how to mimic that effect without using my xenguest-installer program, so that when I pop a CD in and the installer starts up, I can specify a logical volume and let the installer treat it as a physical drive just like the xenguest-installer program does. I am trying to accomplish this because I was unable to install FC4 via the xenguest-installer. I had mounted the image as a loopback device to /var/ftp/pub and specified the /pub directory in FTP server's root folder as my "Installation source", and was greeted by an error from my FTP server (vsftpd) saying "550 Failed to change directory". When I do the exact same thing except mount the FC6 iso instead of the FC4 iso, everything works fine. What could I be doing wrong? If all else fails, I guess I can just specify in my /etc/xen/xm- fc4-001 file the kernel and the ramdisk parameters, and install FC4 on an ext3 formatted logical volume specified as the / directory, and thus reuse my existing /boot directory instead of trying to use the pygrub bootloader with a new /boot directory. In this case, where could I find a compiled xenU kernel and an appropriate initrd image for FC4? Thank you very much and happy new years to all! Justin Wickett Duke 2010 http://www.duke.edu/~jyw2

"No drive found, to create filesystem"...problem with fedora 6 paravirtualization
by Vania Martino Toma 07 Jan '07

07 Jan '07

Hi, i've installed fc6xen, the service of XEN and the Domain0 starts correctly. I've tried to install another fedora6 paravirtualized and i've selected installation in 1 large file (xen1) with 5 GB of space limit in /home/b4y path. The installation in VNC starts correctly, but in the window to create the partition structure, not appears the virtual hard drive. The installation stops with the message " no drive found, to create filesystem...". Help me, please!!! Best regards Vania Toma

HVM guest does not start anymore (dma_timer_expiry)
by Felix Schwarz 07 Jan '07

07 Jan '07

Hi, I'm using Xen on a FC6 (x86_64) system (Dell E521, AMD X2 4200 with Pacifica-Support) with a number of different guest systems (paravirtualized as well as fully virtualized ones). One of these is a FC6 (i386), running in HVM mode (because AFAIK x86_64 Xen does not support i386 paravirtualized guests). Everything worked fine so far. Today, I did a yum update in the guest machine, loading the updates of the last 2-3 weeks. This was okay to. Unfortunately, the guest won't start anymore. I'm getting these boot messages (manually typed in here, typing errors may be present): ... no fstab.sys, mounting internal defaults Switching to new root and running init. unmounting old /dev unmounting old /proc unmounting old /sys ... wait for some time ... hda: DMA interrupt recovery hda: lost interrupt hda: dma_timer_expiry: dma status == 0x24 (again and again) My host system is fully patched as as of 01/06/2007 and so is the guest system. As a special exception, I am running kernel version 2.6.18-1.2857.4.2.fc6.0.2.sctxen on the host system in order to get my Broadcom network chipset working. I can boot the guest just fine using qemu from Fedora Extras. Other HVM guests (such as FC5 i386) are booting just fine. Any ideas? fs

problems with rhel4(clone) as DomainU on FC6 Xen host
by Jeroen Beerstra 07 Jan '07

07 Jan '07

hi there, I am currently playing around with the Xen support in FC6. Installation of Xen and FC6 Domain0, setting up a FC6 guest with virt-manager all went well, however I did not succeed in running a second RHEL4(clone) guest I prepped with Qemu. It took quite some time to figure things out, firstly the host is x86_64 and the guest is/was a 32 bit X/OS (Dutch RHEL clone) desktop , but if I understand things correctly there shouldn't be any problems when running a 64 bit kernel with 32 bit userland. Then I had to learn that a initrd for domain0 is not the same as one for a domainU :) After that the guest booted with the FC6 Xen kernel when I disabled SELinux , however udev fails to start which makes the bootup stop on filesystem check time because I used the default LVM setup and the LVM devices are not created, so the rootfs cannot be found. The repair shell however showed the rootfs is mounted on /dev/mapper/VolGroup00-LogVol00 ro and a remount rw does work even though /dev/mapper/VolGroup00-LogVol00 does not seem to exist :? So I decided I needed a Xen enabled RHEL4 x86_64 kernel and got it from http://people.redhat.com/~jbaron/rhel4/RPMS.kernel/. I could also convert the image to a non LVM one (the Centos4.4 guest from jailtime.org does bootup properly even though it has the same udev problem, because of this), but I rather have a fully functional X/OS. Ofcourse there were problems. I could not install the x86_64 kernel inside the X/OS guest booted with Qemu so I tried manually putting things in place. Running '/sbin/new-kernel-pkg --package kernel-xenU --mkinitrd --depmod --install 2.6.9-42.36.ELxenU' produced some errors related to strip and 64bit kernel modules, but the initrd got created. I'm sure I can work around this if needed, however Xen crashes on the RHEL4 Xen kernel right away: # xm create -c VirtualXOS4_test Using config file "VirtualXOS4_test". Started domain VirtualXOS4 xen_start_info @ffffffff8068a000 shared @m0000fc7000 @ffffffff80107000=@ffffffffff5fd000 [0x802] xen_start_info: @ffffffff8068a000 cr3 0000000000101000 pml4p ffffffff80101ff8 pml4e 0000000000103067 (real 0000000028292067) pgdp ffffff8000103ff0 pgde 0000000000105067 (real 00000000064cc067) pmdp ffffff8000105018 pmde 0000000000693067 (real 0000000066165067) ptep ffffff8000693450 pte 001000000068a027 (real 0010000006c13027) xen_shared_info: @ffffffffff5fd000 cr3 0000000000101000 pml4p ffffffff80101ff8 pml4e 0000000000103067 (real 0000000028292067) pgdp ffffff8000103ff8 pgde 0000000000000000 is none PAGE_OFFSET+1.2: @ffffff8000001000 cr3 0000000000101000 pml4p ffffffff80101ff8 pml4e 0000000000103067 (real 0000000028292067) pgdp ffffff8000103000 pgde 0000000000694067 (real 00000000567a2067) pmdp ffffff8000694000 pmde 0000000000695067 (real 0000000067e6c067) ptep ffffff8000695008 pte 0000000000001167 (real 0000000008709167) Is the RHEL4 Xen kernel incompatible with FC6 Xen?

System hang when starting cups in Xen
by Andre Vehreschild 05 Jan '07

05 Jan '07

Hi, I installed the current xen-kernel on a FC6 and tried to boot it on my Intel Core 2 Duo. Everthing seems fine until the system tries to start the printer-service cups for a locally connect parallel port printer. It simply hangs forever. After a reboot, I checked if the non xen-kernel is able to boot: It is. Next I went into the interactive mode, when rebooting into xen. I neglected the start of cups and the system continued to start up upto the yum-updatesd. Then hanging again. Do I miss something? Do have to configure something before I am able to install the rpms as provided by Fedora? I use Fedora Core 6 with the most recent updates kernel-xen-2.6.18-1.2869.fc6 on an Intel Core 2 Duo E6600 1GB Ram on a Gigabyte 965G Board. Thanks in advance for any advices.

Xen error on FC 5, problem creating guest
by Pushkar Pande 04 Jan '07

04 Jan '07

Hi, I am working on a P4, 2.4 GHz intel system with 512 MB of RAM. I installed the xen0 and the xenU kernel that comes along with the installation DVD. I am able to boot xen, and the 'xm list' command shows the Domain-0 running. I tried to build a guest with the following config file kernel="/usr/lib/xen/boot/hvmloader" name="FC5Guest" memory=256 root="/dev/hda1" disk=['phy:/root/temp/disk.img,hda1,w'] vif=[''] saved to fc5-inst when i tried to create the guest using 'xm create -c fc5-inst' , i get the following error 'Error creating Domain: (22, 'Invalid Argument') ' I am new to xen, please help me out.

virt-install "ERROR: CD device must exist"
by Mike Julier 03 Jan '07

03 Jan '07

I am: New to Linux New to Xen Working with new(er) motherboard (intel DG965SS). When running virt-install I get to the "what would you like to use for the virtual CD image?" question I get "ERROR: CD device must exist!" I have tried answering the question with: - nfs:192168.1.2:/tmp/LinuxInstallTree <-- a directory with the contents of the install DVD - nfs:192.168.1.2:/tmp/LinuxInstallDisk <-- a directory containing the .iso file of the install DVD - nfs:192.168.1.2:/tmp/LinuxInstallDisk/FC_6.x86_64.DVD.iso <-- the .iso file itself When I did the original install of the host (Dom0) I had to use the "linux all-generic-ide" command/option because of some sort of issue where the install script could not see the CD drive once it was ready to start actually installing. Unfortunately I have no idea if the CD error is saying that I haven't done something correctly on the host OS or if the install of the guest is barfing or obviously about to barf so the script is killing it early. I can't see the CD drive when running either the .fc6 or .fc6xen kernels. (I'm under the impression that would be hoping for too much given my inexperience and newness of the mobo.) Thanks for any help. Please feel free to ask any clarifying questions.

error mounting /proc: any solution ?
by Frank Morane 03 Jan '07

03 Jan '07

Hi, This problem has been around since September 2006. The last working version I used was vmlinuz-2.6.16-1.2133_FC5xenU under vmlinuz-2.6.16-1.2133_FC5xen0. The domu I try to run is CentOs 4.4 which runs fine under FC5. The reason I want to make it work is that we have production servers and we wish to avoid having to re install everything and migrate a big bunch of domains and database etc. I am trying to run my existing domU with FC6 but I cannot get passed this root system problem. I tried with other distros and get the same problem, same thing with XenExpress. I am waiting from XenSource to find out if they can help but probably too much champagne on new year's day is delaying response. If possible I would rather stick with FCX as I had it running without too much problem for 18 months but the updates have become problematic since September. I have read many, many people talking about this over the last 4 months but not a single solution to the problem, has anyone a detailed howto to get it up and running? I tried the faq about initrd, I am no iniscript expert and I failed, I tried with binaries, I tried compiling from source with many variant, with and without modules (or builtin) etc. Alway the same result. All log simply confirms the problem below. Also, can it be run under a FC6 dom0 on a Opteron if the domU is i686? Finally, the doc on setting up a VMX is rather sparse, can someone point to a more detail howto? Regards, [root@localhost xen]# xm create -c thoreau Using config file "thoreau".

Hi, I am starting my install like this, virt-install -n cpansearch -r 768 -f /dev/vgmirror/xm-cpansearch -b xenbr1 -p -l http://mirrors.la.sol/fedora/install/x86_64/ --vnc -d -x ks=http://mirrors.la.sol/fedora/ks/xen.cfg -d My kickstart file is at http://tmp.askask.com/2007/01/xen.cfg After all the RPM are installed, I get the following crash. This is with the most recent fedora 6 updates on the Dom0 system. I've tried doing the install both with a "clean FC6" tree and with a tree that had the updates merged in. Traceback (most recent call first): File "/usr/lib/booty/bootloaderInfo.py", line 711, in writeGrub f = open(instRoot + cf, "w+") File "/usr/lib/booty/bootloaderInfo.py", line 1188, in write justConfig | (not self.useGrubVal)) File "/usr/lib/anaconda/bootloader.py", line 187, in writeBootloader justConfigFile, anaconda.intf) File "/usr/lib/anaconda/dispatch.py", line 199, in moveStep rc = stepFunc(self.anaconda) File "/usr/lib/anaconda/dispatch.py", line 122, in gotoNext self.moveStep() File "/usr/lib/anaconda/gui.py", line 923, in nextClicked self.anaconda.dispatch.gotoNext() File "/usr/lib/anaconda/iw/progress_gui.py", line 243, in renderCallback self.intf.icw.nextClicked() File "/usr/lib/anaconda/gui.py", line 950, in handleRenderCallback self.currentWindow.renderCallback() IOError: [Errno 30] Read-only file system: '/mnt/sysimage/boot/grub/ grub.conf' Any ideas? - ask -- http://develooper.com/ - http://askask.com/
