[libvirt-users] Problem attaching device
by steven765＠yahoo.com
I keep getting an error when I try to attach a device in the libvirt api through python
The python code is:
conn=libvirt.open('qemu:///system')
dom = conn.lookupByName("fedoratest")
if dom.info()[0]==1:
dom.attachDevice('net.xml')
And I keep getting: "libvirtError: XML description not well formed or invalid
The xml is a simple network card that works fine in virsh. It is just:
#cat net.xml
<interface type='network'>
<mac address='52:54:00:00:fe:5c'/>
<source network-'default'/>
target dev='vnet1'/>
</interface>
I've tired giving it the full path still no luck.
Thanks in advance,

[libvirt-users] Libvirt using ssh
by Marco Mornati
Hello,
I'm looking that using libvirt Java library with ssh, when connection
is closed the ssh process used as connection to hyperisor is not
closed. Is there a different way than close invoking to kill that
process? If not maybe there is something to fix in java porting.
Let me know
Bye

[libvirt-users] Migrating domains across nodes
by Sagar Dixit
Hi,
I am exploring the migration APIs and was curious to know if I can use them
with LXC containers for live migration from one node to another.
If not LXC, then can I use them with OpenVZ containers ? If yes, what would
be the general steps involved.
Thanks,
Sagar

[libvirt-users] virsh domxml-to-native xen-xm request

Hello,
I was looking at http://libvirt.org/drvxen.html

The configuration is for stubdom-dm Xen guests.
Syntax appears to be virsh domxml-to-native xen-xm new_vm1.xml > /etc/xen/new_vm1 but I get an error.

[libvirt-users] issues with Migrating a domain
by mawei
Hi everyone
i've been trying to migrate a domain from hostA to hostB.But everytime i did it with
"virsh --live migrate <Domain> xen+ssh://root@Destination",
it failed and told me something like
"Error Domain not found:xenUnifiedDomainLookupByName".
The same thing happened when i tried to do the same thing with libvirt API like virDomainMigrate & virDomainMigrateToURI.
i am confused about this.
So can anybody can tell me why?Thanks a lot.
BTW ,my OS is CentOS 5.4 and my hypervisor is xen3.1.2 which is installed with the OS.And the libvirt version is 0.7.7.
THANKS A LOT AGAIN.

[libvirt-users] Pool, iSCSI and guest start
by Nicolas Greneche
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi,
Former user of Xen and newbie in kvm/qemu/libvirt stuff, I give it a try
on my network ;-)
I need to run a VM with iSCSI target attached.
I did it this way :
1) Creation of iscsi pool (equa.xml) :
<pool type="iscsi">
<name>equalog</name>
<source>
<host name="10.10.0.1"/>
<device
path="iqn.2001-05.com.equallogic:0-8a0906-4992c7f05-39c000000114b8fc-vglog"/>
</source>
<target>
<path>/dev/disk/by-path</path>
</target>
</pool>
This pool start smoothly (when open-iscsi started), no problems. An
entry is created in /dev/disk/by-path/ related to iscsi target.
2) I flagged it autostart :
root@sandi:~# virsh pool-autostart equalog
Pool equalog marked as autostarted
root@sandi:~# virsh pool-list
Name State Autostart
- -----------------------------------------
equalog active yes
3) In my guest VM, I have following section :
<disk type='block' device='disk'>
<driver name='qemu'/>
<source
dev='/dev/disk/by-path/ip-10.10.0.1:3260-iscsi-iqn.2001-05.com.equallogic:0-8a0906-4992c7f05-39c000000114b8fc-vglog-lun-0'/>
<target dev='vdc' bus='virtio'/>
<alias name='virtio2'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x06'
function='0x0'/>
</disk>
When I start VM, iscsi target is availaible.
The snag is that when I reboot the host, the pool is not automatically
started (making it impossible to autostart VM relying on this iscsi volume).
I verified that open-iscsi is started first. Startup script is localised
in /etc/rcS.d which is prior to /etc/rc2.d (my default runlevel).
Libvirtd is started in rc2.d and not mentionned in rcS.d.
My questions are :
- - Is this the correct way to attach iscsi volume to a guest ?
- - Did I missed something to have iscsi pool autostart working at boot
time ?
My environement :
Debian Squeeze 64 bits
root@sandi:~# virsh -v
0.7.6
root@sandi:~# /usr/sbin/libvirtd --version
/usr/sbin/libvirtd (libvirt) 0.7.6
Thanks for your attention,

[libvirt-users] virsh shutdown does not stop XP-Pro guest
by Don Morrison
I've been trying to get "virsh shutdown" to work against an XP-Pro guest
with no luck so far. It seems to have no effect - I have to run "virsh
destroy" instead which is less than desirable. I have enabled <acpi> in the
domain xml so I think the problem is on the guest side. A couple of
questions:
1) How can I confirm whether the XP guest has ACPI enabled. I actually
think it doesn't because when I look at the "ACPI Multiprocessor PC"
device driver name, it lists "hal.dll". This is NOT ACPI enabled according
to this site: http://technet.microsoft.com/en-us/library/bb457123.aspx. Am
I reading this correctly?
2) I tried to enable ACPI at install time by bringing up virt-viewer and
pressing F5 on the blue install screen as instructed here:
http://www.computing.net/answers/windows-xp/enable-acpi-in-xp-without-rei...
But F5 didn't have any effect. Has anybody else been able to get this to
work?
I'm running KVM 0.12.2-0.4.1 and Libvirt 0.7.6-1.2.3
Thanks.

[libvirt-users] migrate with libirt 0.7.0
by Daniel Bidwell
Using ubuntu 9.10 and libvir 0.7.0, when I do a migrate a domain from
machine A to B, the migration "completes" but remains in a frozen state
until I do a "suspend/resume" on it on B. Then it runs fully normally.
What do I do to skip the suspend/resume steps?

[libvirt-users] internal error cannot parse QEMU version number
by jeremy avnet
I've seen this error a couple of times over the past month, but it's
starting to happen more regularly now (perhaps since VM usage is
increasing). The last few times I've seen it when trying to start a VM
(virsh start domain):
$ virsh start goat
Connecting to uri: qemu:///system
error: Failed to start domain goat
error: internal error cannot parse QEMU version number in ' PC emulator
version 0.11.0 (qemu-kvm-0.11.0), Copyright (c) 2003-2008 Fabrice Bellard'
Running libvirt version 0.7.0-1ubuntu13.1 under Ubuntu 9.10 amd64.
$ kvm --version
QEMU PC emulator version 0.11.0 (qemu-kvm-0.11.0), Copyright (c) 2003-2008

I saw this message, but it's for an older version:
http://osdir.com/ml/libvir-list/2009-05/msg00192.html
Any ideas on how to prevent this error?
Thank you.
