Hi,
I'm using libvirt 0.6.2 to create a Xen guest with a network type
interface (see XML below). When the guest is defined, the interface is
converted to an ethernet type interface. If the guest is started, the
interface is then converted to a bridge type interface.
This sounds bad :-) Can you provide the output of 'xm list --long hd_domain'
immediately after defining it, and then again immediately after starting
the guest.
Here's the whole create process. Probably more than you needed, but
included for clarity ;)
# virsh list --all
Id Name State
----------------------------------
0 Domain-0 running
# virsh define hd_domain
Domain hd_domain defined from hd_domain
# xm list --long hd_domain
Error: Domain 'hd_domain' does not exist.
Usage: xm list [options] [Domain, ...]
List information about all/some domains.
-l, --long Output all VM details in SXP
--label Include security labels
