[libvirt-users] Problem with libvirt migration

I have two hosts, vm1 and vm2, which are both running libvirt 0.7.0.
They share a common ocfs2 file system that resides on a san, and have
identical network configurations.  I am running qemu-kvm 0.11.0 on
ubuntu 9.10 servers.

I start base32 on vm1 and it comes up (it also runs fine if started on
vm2).  Then from vm2 I do:
	vm2#: virsh -c qemu://vm1/system
	migrate --live base32 qemu://vm2/system

The migration starts and the vm2 virsh returns to the prompt.  vm2 shows
base32 as running and vm1 shows base32 as stopped.  The console for
base32 on vm2 is frozen and unresponsive.

I have the debug level set to 1 on both machines.

This is an excerpt from the virsh.log file from vm1:

The migration appears to have completed successfully, but the console
doesn't respond to anything and neither does the ethernet.  Any ideas on
how to get past this last step?

[libvirt-users] Problem with libvirt migration

I had a similar problem using

   Debian Lenny
   libvirt-0.7.6
   qemu-kvm-0.12.3 (build from GIT sources)

and I solved it by replacing

   qemu-kvm-0.12.3

with

   qemu-0.12.3 (build from sources...)

I hope to be helpful....
