Re: [libvirt] [Openstack] 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.
