Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service libvirt-bin restart
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the restart(8) utility, e.g. restart
libvirt-bin

[libvirt-users] Setup Mulitple VM's
by ssaleh＠nrln.us
I have a small public IP block (/29) I'd like to populate with VM's from a single physical box running CentOS/5. I'd like to get some thoughts on the best way to setup networking to support this. I'm OK with setting up the virtual hosts.
Any advice would be appreciated.
TIA...

[libvirt-users] 2 hosts, mirrored VM storage, avoiding conflicting VM instances
by Whit Blauvelt
Hi,
Using libvirt for KVM, experimenting with live migration with the VM on
storage shared in a mirrored GlusterFS or an active-active DRBD setup where
QEMU/KVM runs on the hosts on both sides of the mirror, the live migration
works great. What concerns me is finding a way if possible to prevent a
situation where a particular VM is running on both hosts at once. Is there
any way within libvirt in this sort of setup to start a VM on mirrored
storage from a KVM host on one side of the mirror _only if_ the same VM
isn't already running on the other side of the mirror?
In a scripting context I can see how to do that check before starting, but
not how to prevent virsh or virt-manager from being used to create this bad
condition when they're being used directly. Is there some way to set up
protection from this within virsh and virt-manager? Or am I into feature
request territory? Or is there some other layer at which this can be
accomplished?
In active-passive DRBD this wouldn't be a danger, since only the active
system can see the storage to start the VM. But that wouldn't support live
migration. Part of the danger can be avoided by using stonith in failover,
but it would be nice to find a more fine-grained, subtle approach.
Best,
Whit

[libvirt-users] PCI Pass through of atheros card
by Varun Ganesh
Hi,
I am trying to make a PCI passthrough of the atheros card to a VM running
over KVM. am following the steps given at
http://docs.fedoraproject.org/en-US/Fedora/13/html/Virtualization_Guide/s....
but am getting the following errors,
1. Error starting domain: operation failed: failed to retrieve chardev
info in qemu with 'info chaqdev'
2. Details:
3. Error starting domain: operation failed: failed to retrieve chardev
info in qemu with 'info chaqdev'

I am using a Dell Optiplex XE system which has VT-d enabled and Atheros
AR5001X+ Wireless Network Adapter. How do i rectify this.
Thanks,

[libvirt-users] domain not present after shutdown
by David White
I hope this is simple
I have one kvm host that lists all my domains even after shut down. 'virsh list
--all' shows machines in 'running' and 'shut off' states. If I copy those over
to another machine and it only shows the virt machines in running state.
vmhost2:~$ virsh list --all
Id Name State
----------------------------------
4 mybox4 running
vmhost2:~$ virsh version
Compiled against library: libvir 0.8.3
Using library: libvir 0.8.3
Using API: QEMU 0.8.3
Running hypervisor: QEMU 0.12.5
vmhost1:~$ virsh list --all
Id Name State
----------------------------------
- mybox3 shut off
2 mybox4 running
vmhost1:~$ virsh version
Compiled against library: libvir 0.7.5
Using library: libvir 0.7.5
Using API: QEMU 0.7.5
Running hypervisor: QEMU 0.12.3
question -- why doesn't mybox3 show up on vmhost2? where should I start looking?
hope this isn't too open ended...

[libvirt-users] No IOMMU found. Unable to assign device
by Marco van Beek
Hi,
I am playing around with PCI passthrough and came across some posts that
said you could not do PCI passthrough unless you had IOMMU hardware.
which it would appear I don't
Is this the case? Am I flogging a dead horse?
Thanks,
Marco
