initscripts, xen and bonding
by Axel Thimm
Hi,
I'm having a hard time getting bonding to work on FC5t3. It looks like
the bond0 interface bond0 is renamed to pbond0 by xen [*] and the
enslaving does not work anymore then. It works if I log on the
terminal and ifenslave the devices to pbond0 instead of bond0 after
the boot process has finished.
But I want this to be handled automatically during reboots, so I tried
assigning the bonding slaves to pbond0 as a master in the
ifcfg-eth{0,1} scripts, but that doesn't work.
What is causing the bond0 rename and should this renaming be
considered by initscript? Is this a user error or should I file this
against bugzilla? xen or initscripts?
Thanks!
[*] The only reference I found was a Japanese site and google's
translation of it.

Simple testing results for Xen and VMX on FC5-test2.
by You, Yongkang
Hi all,
I have done a simple checking for Xen and VMX on FC5-test2. Basically, I can create VMX on FC5-test2 IA32. But FC5-test2 IA32e (x86-64) doesn't provide Xen and Xen0 kernel, so didn't do Xen and VMX testing for it.
Beside of testing Xen and VMX, I also found some issues about installation, which I have updated the bug #179078 as a NB. The following is the testing results only for Xen and VMX.
=========================
1. *** IA32E hasn't RPMS about Xen hypervisor and Xen0/XenU kernels. __FAIL__
2. *** In order to boot up IA32 Xen0, I have to add pci=noacpi as the boot
parameters of Xen0 kernel, or system will hang when initial PCI. I don't know if it is only related to my Machine. __FAIL__
3. After install IA32 Xen RPMs, I can see /boot/grub/grub.conf has been changed
with Xen kernels. __PASS__
4. *** /usr/lib/xen/boot/vmxloader isn't in the RPM package, so VMX Guest
couldn't be created. I suspected build system hasn't bcc, it is from DEV86
package. __FAIL__
5. After copy a useable vmxloader to the destination, IA32 VMX Guest can be
created successfully! __PASS__
6. VMX has good network connection and Xwindows started. __PASS__
7. XenU can be created and works well. __PASS__
8. Couldn't get Xen Changeset by "xm info" or "xm dmesg".
9. The new kernel names of Xen/Xen0/XenU seemed a little confused. E.g. the Xen0 name is like vmlinuz-2.6.15-1.29_FC5hypervisor. I thought hypervisor is for Xen.gz. Xen0 is the Service OS.
==========================
Any comments please let me know. But I will have 8 days holiday from tomorrow, so emails reply might be slow and occasional.
[FYI] We are planning to do more testing for FC5-test3.
Best Regards,
Yongkang (Kangkang) 永康

Console Hang On Boot Using 2.6.18-1.2200.fc5xenU
by Stan Larson
Sorry if this is a repeat. I haven't found searchable archives for this
forum yet.
1. I installed FC5 + xen on a base system and performed "yum -y upgrade".
2. I then created and booted a DomU using the original FC5 disk. So
far, so good.
3. In the DomU, I performed "yum -y upgrade" and rebooted the DomU
using the new kernel, 2.6.18-1.2200.fc5xenU.
The DomU boots OK, but returns control or starts a shell. The console
starts all services and then just hangs. I can ssh into the domain
from another window and all is well. If I break from the console using
CRTL-] and then return using xm console, I'm still stuck. If I boot to
the old kernel (the one provided by the FC5 install disk, aka
2.6.15-1.2054_FC5xenU) the problem doesn't occur.
Any suggestions?

FC5 updated Xen RPMs in updates-testing
by Daniel P. Berrange
Hi Folks,
After working through the many many BZ tickets & mailing list threads on
the subject of broken FC5 kernel-xen / xen recently, I've finally got new
packages available in updates-testing for wider testing. Design to work
against the latest 2.6.18-1.2200.fc5 kernels is:
xen-3.0.3-1.fc5 (fixes the xen userland in general)
kudzu-1.2.34.5-1 (ensure that agetty is started on xen serial console)
The two related update notices are on fedora-test-list:
http://www.redhat.com/archives/fedora-test-list/2006-October/msg01060.html
http://www.redhat.com/archives/fedora-test-list/2006-October/msg01056.html
Note, with these updates you can now use the full graphical framebuffer
in para-virt guests too. Just add 'vnc=1' in the guest config. As with FC6
it listens on 127.0.0.1 by default, which can be changed with a config
param vnclisten=0.0.0.0, although if doing that its wise to also add
the vncpassword='XYZ' parameter too. The 'vncunused=1' parameter will make
it auto-pick the first unused VNC display, rather than hardcoding the
port to be 5900+domid.
Regards,
Dan.

I create one, the install goes fine, as it is installing I see it with

I hit reboot in the installer after it is finished, then it just
dissappears.

Brigde configuration
by Tiago Cruz
Hello again fedora-guys!
I'm getting one strange problem with FC5 running on XEN 3.0.3 x64, and I
suspect of my bridge configuration (I never did this before on fedora):
File sysconfig/network-scripts/ifcfg-eth0:
DEVICE=eth0
TYPE=Ethernet
BRIDGE=xenbr0
ONBOOT=yes
File sysconfig/network-scripts/ifcfg-xenbr0:
DEVICE=xenbr0
TYPE=BRIDGE
BOOTPROTO=dhcp
ONBOOT=yes
Is it correct this bridge configuration?
Because I have a lot of messages on my console, like this (dmesg):
printk2: 2 messages suppressed
vif0.0: "received packet with own address as source address"
printk2: 4775 messages suppressed
vif0.0: "received packet with own address as source address"
printk2: 165845 messages suppressed
vif0.0: "received packet with own address as source address"
printk2: 186540 messages suppressed
xenbr0: port 3(eth0) entering disabled state
xenbr0: port 1(vif0.0) entering disabled state
device eth0 left promiscuous mode
audit(1161983401.126:10): dev=eth0 prom=0 old_prom=256 auid=4294967295
xenbr0: port 3(eth0) entering disabled state
And the worst part: The MRTG point to my machine with XEN running one
absurd volume of output data sent (normal is around 6 MB/s) and when XEN
is working we get 80 MB/s until my DRAC is alive... after this, the
machine crash, DRAC stop to reply, swith stop do work together...
Anyone knows whats happening now? ;)
Many thanks for any comments!

What is the magic mount sauce?
by Paul Clark
I want to mount my local CDROM to create a new guest using the
Paravirtualization. Other parameters are RAM=512mb, disk=5gig, and
cpu=1. I have tried the HTTP and NFS protocols. I was able to access
the drive and files from another machines so I know I have the network
configuration correct. BUT... when I pass the location to the
xenguest-install script and the virt-manager I receive an error about
the URL.
ERROR: Invalid URL location given: [Errno 14] HTTP Error 404: Date: Sun,

What I think is weird is when I use the Fedora site it works,

Any ideas?

xenguest-install error
by Adrian Chadd
This is from FC5:
Starting install...
libvir: error : operation virDomainCreateLinux forbidden for read only access
Traceback (most recent call last):
File "/usr/sbin/xenguest-install.py", line 460, in ?
main()
File "/usr/sbin/xenguest-install.py", line 451, in main
start_paravirt_install(name, ram, disk, mac, uuid, src, options.extra)
File "/usr/sbin/xenguest-install.py", line 331, in start_paravirt_install
dom = conn.createLinux(cfgxml, 0)
File "/usr/lib/python2.4/site-packages/libvirt.py", line 249, in createLinux
if ret is None:raise libvirtError('virDomainCreateLinux() failed')
Changing to call to openReadOnly() to open() (as per an August post to
fedora-devel suggests) gives this:
Traceback (most recent call last):
File "/usr/sbin/xenguest-install.py", line 460, in ?
main()

File "/usr/lib/python2.4/site-packages/libvirt.py", line 39, in open
if ret is None:raise libvirtError('virConnectOpen() failed')
libvirt.libvirtError: virConnectOpen() failed
Has anyone successfully used xenguest-install.py under FC5 recently?

Problems with pciback.hide
by Patrick Heckeler
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi folks,
I installed sucessfully 2 virtual machines on a fedora core 6 system.
When I try to use the grub command "pciback.hide", I retrieve an error
message while booting my dom0... I read an article which says, that it
might be possible, that the pciback.hide feature is not activated in the
kernel... Does anybody know how to activate this feature?
Thanks a lot...
