Hi Kei, I use the Diablo release of openStack and I didn't change anything in the libvirt XML template. I can saw a difference for the console file. The trunk version of Nova use a file for the logging console but the Diablo Release use a pipe. Can I change it manually ? Must I open a bur for Diablo release ? Regards, Doude.

I think you should use exactly same template as below. https://github.com/openstack/nova/blob/master/nova/virt/libvirt.xml.template

Hi all,

I use OpenStack Diablo release 2011.3-0ubuntu6.2 on ubuntu 11.10 with libvirt 0.9.2-4ubuntu15.1

I try to block migrate a VM from one host to another one. OpenStack uses the 'migrateToURI' method from libvirt python library. But this call fails.

Libvirt log : - Source host: 18:27:30.475: 24622: error : remoteIO:5985 : unable to set user and group to '107:118' on '/var/lib/nova/instances/instance-000000b7/console.fifo.in': No such file or directory - Target host: 27:29.737: 27244: error : virSecurityDACSetOwnership:125 : unable to set user and group to '107:118' on '/var/lib/nova/instances/instance-000000b7/console.fifo.in': No such file or directory 18:27:29.917: 27244: error : virSecurityDACRestoreSecurityFileLabel:143 : cannot resolve symlink /var/lib/nova/instances/instance-000000b7/console.fifo.out: No such file or directory

So the migration fails. VM disks are transfered to the target host but console files aren't.

        <graphics type='vnc' port='-1' autoport='yes' keymap='fr' listen='0.0.0.0'/>     </devices> </domain>

Could you help me ?
