Hosts:
CPU: Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz
RAM: 2GB
Disk: Gbit NFS-mount on NetApp FAS3040 (/etc/libvirt/qemu)
10.0.40.100:/vol/hl/disk_images /etc/libvirt/qemu/disks nfs
rsize=32768,wsize=32768,hard,intr,tcp,timeo=600,rw 0 0
Installed both hosts with Ubuntu Jaunty 9.04.
aptitude install libvirt-bin qemu kvm host sysstat iptraf iptables portmap
nfs-common realpath bridge-utils vlan ubuntu-virt-server python-vm-builder
whois postfix hdparm
After some testing with migration (all failed because of several
errors/bugs) I upgraded to Ubuntu Karmic 9.10 Beta.

Define instance:
/usr/bin/virsh define /etc/libvirt/qemu/xml/1378/fqdn.com.xml
Start instance:
/usr/bin/virsh start fqdn.com

Migrate instance:
/usr/bin/virsh migrate fqdn.com qemu+ssh://hostb.fqdn.com/system
Migration will complete but the instance seems to be suspended.
On HostB to resume the instance:
/usr/bin/virsh suspend fqdn.com
/usr/bin/virsh resume fqdn.com
Only running resume fqdn.com does nothing.
The Hosts were initialy installed as Ubuntu Jaunty 9.04 and upgraded to
Ubuntu Karmic 9.10 Beta. Maybe this is the problem?
