Guest shutdown problems
by Christian Axelsson
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.
Regards,
Christian Axelsson

Cannot start HVM DomU
by Robert Locke
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,

Custom bridge script; upgrade from Fedora 6 to Fedora 8
by Ask Bjørn Hansen
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?

Guest boots OK with ATA disk (hdX) but not SCSI (sdX).
by Friedrich Clausen
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 :

I am glad I can successfully boot a guest but I would still like to get to

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
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

RHEL5 - Xend will not start after software upgrade
by Ubaidul Khan
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

Libvirt and xenstore - glitches on migrate
by Jim Klein
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
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.
