I don't know if this applies to you, but it took me some time
to figure out how to start the vm instance correctly.
from http://howtoforge.org/virtualization-with-kvm-on-ubuntu-9.04-p3
"Before you start a new VM for the first time, you must define it from
its xml file (located in the /etc/libvirt/qemu/ directory):
define /etc/libvirt/qemu/vm1.xml"
Are you doing
$ sudo virsh
virsh # define /etc/libvirt/qemu/<myvm>.xml
virsh # start <myvm>
then
$ ssh me@<myvm addr>
or
$ vncviewer 127.0.0.1
?
Thanks,
Kent
