Yes, the image contains an OS (it works if I start the guest manually).

[libvirt-users] Problems with libvirt / qemu
by Dan Johansson
HI,
I have a small problem with libvirt / qemu. I have created a guest and when I start it from the command-line the guests starts OK, but when I start the guest through libvirt with "virsh start" I get "Booting from Hard Disk...
Boot failed: not a bootable disk
No bootable device"
This is the command-line I use to start the guest (which works)
"cd /var/lib/kvm/Wilmer; /usr/bin/qemu-system-x86_64 --enable-kvm \
-net nic,vlan=1,model=rtl8139,macaddr=DE:ED:BE:EF:01:03 -net tap,vlan=1,ifname=qtap13,script=no,downscript=no \
-net nic,vlan=3,model=rtl8139,macaddr=DE:ED:BE:EF:03:03 -net tap,vlan=3,ifname=qtap33,script=no,downscript=no \
-m 2048 -k de-ch -vnc :3 -daemonize \
Wilmer.qcow2"
The libvirt XML-file was created using "virsh domxml-from-native qemu-argv" and this is the result of that conversion:

[libvirt-users] Ruby-libvirt and openAuth

Hello,
It looks like the Ruby bindings do not support virConnectOpenAuth. Is this
true? If so, is there any reason why? or plans to?

[libvirt-users] Monitoring and statistics through libvirt
by Tomi
Hi folks,
is it possible to monitor and gather statistics in realtime (CPU,
memory, HDD, network, ... - something like dstat) of guest systems
with libvirt through console from host system (KVM based)? If yes, do
those guests need to be created through libvirt? Thanks for your help
and time.

[libvirt-users] KVM Live Migration
by Mike Hall
We have the following test environment:
2 x CentOS 5.5 KVM virtual hosts
2 x CentOS 5.5 network storage boxes with NFS shares on LVs on DRBD (primary/secondary, no HA, just replication).
We have installed both CentOS and Win7 guests which live migrate almost instantly between hosts using Virt Manager (or virsh migrate). The problem is that the guests does not retain their running state after migration, but instead arrive on the new host in "reboot after unclean shutdown" state.
The migrated machines also lose IP connectivity (static IP) upon migration to new host, but regain it on migration back to original host.
So, live migration in this case isn't producing the expected results (a running, usable guest). Same results using "migrate offline" option and pausing machines before migration.
Any pointers on what we're doing wrong?
Is there a need for us to implement hook scripts?

[libvirt-users] Mounting an lvm
by Dale Amon
I converted a system disk from a virtualbox
VM and added to the config on a qemu VM.
All seems well until I try to mount it. The
virtual machine shows data for the disk
image using commands like:
pvs
lvs
lvdisplay xena-1
but there is no /dev/xena-1/root to be
mounted. I also cannot seem to figure out
whether the lvm related modules are available
for the virtual machine kernel.
Has anyone else tried playing this game?

[libvirt-users] Puppet Module for Virtualization Management
by Carla Araujo
Hi all!
Puppet [0] is an Open Source data center automation and configuration
management framework. Puppet provides system administration with a
simplified platform that allows for consistent, transparent, and flexible
system management. Puppet can be extended with new modules, which are
reusable, sharable units of Puppet code.
This year, during the Google Summer of Code [1], I developed a new Puppet's
module: Puppet-virt. Puppet-virt [2] provides a new type that allows the
administrator to deploy and manage virtual machines using r *uby-libvirt* .
At first, only Xen fullyvirtualization, Xen paravirtualization, KVM and
OpenVZ are supported.
If you have any suggestion or contribution, fell free to contact me and/or
fork the repository at github. :)
Regards,
Carla Souza
