[Fedora-xen] guest state ---s-d

[Augusto Castelan Carlson]

Hi!

One of my guests (guest1) was not accessible today. The state was
---s-d. Looking at the xen docs, for "s" says that the state is
shutdown, but there is no entry for "d".
Every night I save the guest with
# virsh save guest1 /saved/guest1_saved
and mount the guest1 disk to backup user files, umount the disk and
restore the guest:
# virsh restore /saved/guest1_saved
In the xend.log there was no message about the restore.
When I tried to shutdown (with xm ou virsh) the guest , I received
"Error: Domain cannot be shutdown". Below the " xm list" output and
the error from xend.log

Dom0 and DomU are Fedora 7 with 2.6.21-6.fc7xen, xen-3.1.2-1.fc7,
xen-libs-3.1.2-1.fc7 and libvirt-0.3.2-1.fc7.

xend.log output:
[2008-01-16 08:09:15 2303] ERROR (SrvBase:88) Request shutdown failed.

    raise XendError('Domain cannot be shutdown')
XendError: Domain cannot be shutdown

What is the meaning of the "---s-d" state and what canbe the cause of
this problem?

Thanks in advance!
