[virsh strace]

Hi Suresh,

So first, virsh is just a client, it does almost nothing (I think). What
you want to debug is the libvirtd daemon. You can find the logs in
/var/log/libvirt.
/var/log/libvirt/libvirtd.log would be the daemon itself, and
/var/log/libvirt/libxl/ would contain contain logs about created domain or
any libxl debug I guest.

I usually run `virsh -c xen: list`, where '-c xen:' make it explicite that
we want to do something with Xen.

So, is libvirtd actually running on your machine? Could you have a look
into its logs?

Regards,
