[libvirt] Libvirt block live migration with OpenStack Diablo
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.

Could you help me ?
