Hi,
I am trying to migrate a running instance, but it fails with the following error:
$ virsh migrate --live instance-00000008 qemu+tcp://10.2.3.150/system --verbose
error: operation failed: migration job: unexpectedly failed
I can see following in the instance specific qemu log directory \
(/var/log/libvirt/qemu/instance-00000008.log) on the destination host: 2012-04-12 \
03:57:26.211: starting up LC_ALL=C \

2012-04-12 03:57:26.850: shutting down
can't delete tap57b16714-9a from eth1: Operation not supported
SIOCSIFADDR: Permission denied
SIOCSIFFLAGS: Permission denied
SIOCSIFFLAGS: Permission denied
/etc/qemu-ifdown: could not launch network script
Libvirt version on both hosts:
$ libvirtd --version
libvirtd (libvirt) 0.9.2
$ virsh --version
0.9.2
Here are my libvirtd.conf details:
listen_tls = 0
listen_tcp = 1
unix_sock_group = "libvirtd"
unix_sock_rw_perms = "0770"
auth_unix_ro = "none"
auth_unix_rw = "none"
auth_tcp = "none"
Would be great if someone can point out the issue here.
Note: I have disable apparmor for libvirtd profile and am able to list the instances \
running on the remote host (from both the servers).
Thanks & Regards,
