[libvirt-users] converted VMDK disk iamge and Virtio driver
by Paul Raines
I have a CentOS 5 VM in vmware I wanted to move to work on KVM/libvirt. I used
qemu-img to convert it to a qcow2 image, loaded virt-manager and created a new
VM pointed at that qcow2 image. The boot paniced when it tried to mount
the root filesystem also complaining about not being able to remount the
swap partition.
I played around and was able to get it to boot by changing the Virtual disk
bus to IDE from Virtio. Searched about Virtio and I got to
http://wiki.libvirt.org/page/Virtio and ran the mkinitrd mentioned to force
loading of the virtio_pci and virtio_blk drivers. But upon shutting down,
configuring the bus back to Virtio and booting it panics in the exact same
way.
I tried again after adding virtio_blk into /etc/modprobe.conf as
scsi_hostadapter and rerunning mkinitrd but it still fails.
Any clues what I am missing?

[libvirt-users] dumpxml removes <source> portion from network descritiption
by Thomas Stein
Hello.
I have a strange error with one of my VMs. If i use dumpxml to save a VM
description the source part of the network part is missing. This prevents
redifining the machine from the dumped xml file:
This is how it looks before dumpxml:
<interface type='bridge'>
<mac address='52:54:00:34:a1:56'/>
<source bridge='br406'/>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03'
function='0x0'/>
</interface>
And afterwards:
<interface type='bridge'>
<mac address='52:54:00:34:a1:56'/>
<target dev='vnet6'/>
<model type='virtio'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03'
function='0x0'/>
</interface>
Someone has an idea whats causing this? Is there a special option maybe?
thanks and best regards

[libvirt-users] Use keepalive to monitor health of qemu-kvm process
by Abhijeet Rastogi
Hi everyone,
I've had instances where qemu-kvm process dies and become a zombie. At
that state, libvirtd reports the instance to be running and I can't
restart the VM because libvirtd fails to kill the qemu-kvm process.
Finding the root cause of that is a topic for another day.
I also see this line in logs:
Jun 15 13:36:57 d12566 libvirtd: 10424: warning :
virKeepAliveTimerInternal:156 : No response from client 0x1600420
after 5 keepalive messages in 31 seconds
Is it possible to monitor the keepAlive thing via command-line ? (as a
nagios check). I know that I can poll for that line in the logs but is
there a better way? I couldn't find any option in virsh to do a
KeepAlive check.
Thanks

1) I'm using libvirt version 1.1.1,
libvirt-bin 1.1.1-0ubuntu8.5~cloud0
libvirt0 1.1.1-0ubuntu8.5~cloud0
python-libvirt 1.1.1-0ubuntu8.5~cloud0
2) #cat /etc/libvirt/qemu.conf
...
user = "root"
group = "root"
I searched GOOGLE, René speaks "downgrading to libvirt 1.1.0 and
reinstalling everything. They will ok". But I don't think that.
How to resolve this error?.
Thanks all!

[libvirt-users] Libvirt 1.2.5/Qemu woes
by andy zerger
Hi all -
I'm dealing with a libvirt 1.2.5 and Qemu-1.7.1 also Qemu-2.0 (all source
compile,) which somehow isn't seeing any hypervisors when connected to via
virt-manager.
I'm sure I must be doing something wrong but cannot figure out what. My
basic config and current state here in pastebin:

Thanks for any input, this has been baffling.

[libvirt-users] libvirt issue while deploying a VM
by Zvi Dubitzky
Using libvirt under openstack I encounter a problem when launching a VM
with multiple partitions (2 G image) ,
While a single partition can be launched successfully . The launch is
done with Openstack.
We are using in libvirtd.conf log_level=1 and
log_outputs="1:file:/var/log/libvirt/libvirtd.log"
we can see that in /var/log/libvirt/libvirtd.log appear the following
error message and the VM is finally shutdown :
2014-06-11 14:47:26.166+0000: 12971: error : qemuMonitorIO:614 : internal
error End of file from monitor
( file attached below)
( VM shutdown seen here)
The host has enough resources( we see no complains) and the XML of the
VM is :
The libvirt version is: 0.10.2
The qemu-kvm version: 0.12.1.2
>From the internet we could not figure out a solution to the problem
Any idea what is causing this error and how to overcome ?
Thx

[libvirt-users] libvirt, openSUSE, SuSeFirewall2 and port forwarding
by Johannes Kastl
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hello list,
I thought I had already asked this question, but apparently I just
started writing a draft mail and never sent it (at least I can't find
it in the archives).
Has anyone setup qemu VMs using libvirt on openSUSE, and has gotten
port forwarding to work? I used on of the many scripts out there, that
go into /etc/libvirt/hooks/qemu, and it is being called.
Somehow it seems once in a while SuSefirewall2 just forgets about
iptable rules set with this script. And sometimes they don't appear,
even if the script is executed.
Anyone else having the same issues? Any openSUSE users willing to try
this?
Thanks in advance!
Regards,
Johannes

[libvirt-users] Status of Host machine.
by Sijo Jose
Hi,
Using libvirt how can we check the status of a remote/local host machine..
isAlive() method is giving true even if the internet connection is broken OR
libvirt demon in the remote machine is being stopped.
so isAlive() does not seems to be handy,
Is there some other way to get the status of remote host..?
Thanks
