[libvirt-users] Booting virtual machines automatically
by Daniel Gonzalez
Hello,
I am managing several virtual machines (a predefined set) with virsh, and I
would like to make sure that all VMs are booted when the host reboots.
What is the recommended approach for this?
Thanks,

[libvirt-users] PCI-X card controlled by VM
by Daniel Gonzalez
Hi all,
I have a PCI-X card which I would like to assign to one of my VM guests.
Is there any way, using libvirt, of completely bypassing the host system,
and routing all PCI-X interaction (drivers, interrupts, general ownership)
to one of the VMs?
Thanks,
Daniel Gonzalez

[libvirt-users] qemu - could not load kernel and dynamic ownership setting
by Shantanu Pavgi
Hi,
I am getting following 'qemu: could not load kernel' error while trying to create a new VM using virt-install or virt-manager. The software versions are as follows: CentOS 6.2, Libvirt 0.9.4, qemu-kvm 2:0.12.1.2-2.209.el6_2.1.
The qemu.conf has disabled dynamic_ownership setting. The VM instantiation has worked fine before when dynamic_ownership was enabled (default). So is this error related to dynamic ownership being disabled? I appreciate any help on how to debug this error further.
Also, is there any documentation on why/when dynamic_ownership setting should be used? We have enabled it to figure this out through some test installs but right now unable to move further with the install step itself.

Try one more time and paste /var/log/message (tail -100
/var/log/message) and /var/log/secure (tail -40 /var/log/secure) to
pastebin.com and send link.

[libvirt-users] Unable to connect qemu:///system on CentOS 6.2 X86_64
by suyi wang
Dear all:
I ust installed Fedora16Fedora16 X86_64 on my new machine, and then I
ran the commands as follows(ran as root):
yum install qemu-kvm
yum install qemu
yum install libvirt
yum install virt-manager
then I started the libvirtd as follow:
/etc/init.d/lbvirtd start
So , it ran well.
However, after a few days , when I ran the command "virt-manager" , it
showed as in the attachment.
it seemed that ti cannot connect the hipervisor.
Then I did a little test:
I ran the conmand "virsh list" , but it didnot work,either.
Then I used Python as follows:
import libvirt
cc = libvirt.open(r'qemu:///system'
)
but it didnot work,either.
All the test above are under root . I hope that someone can give me some
suggestiion. Thanks to all!

[libvirt-users] Solution for Address family not supported by protocol
by 4k3nd0
I just upgrade to the last version of the libvirt on my Gentoo System.
(From 0.9.6 to 0.9.10-r3) But i have a problem with starting my NAT:
Error starting network 'NAT': Cannot open network interface control
socket: Address family not supported by protocol
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 45, in

if ret == -1: raise libvirtError ('virNetworkCreate() failed',
net=self)
libvirtError: Cannot open network interface control socket: Address
family not supported by protocol
Anyone have an idea how to fix this? I try also to add a new adapter by
hand, but know seems to work her....
so far
