Hi there,
I am running Ubuntu 9.04 X64 server with KVM/libvirt. I recently found that the "virsh destroy" command actually delete VMs it should not delete.
For example, please see the following screen copy:
root@node1:/srv/cloud/ImgRep/WinXP# virsh list
Connecting to uri: qemu:///system
Id Name State
----------------------------------
27 one-80 running
28 one-81 running
29 one-83 running
30 one-82 running
31 one-79 running
root@node1:/srv/cloud/ImgRep/WinXP# virsh destroy 29
Connecting to uri: qemu:///system
Domain 29 destroyed
root@node1:/srv/cloud/ImgRep/WinXP# virsh list
Connecting to uri: qemu:///system
Id Name State
----------------------------------
27 one-80 running
28 one-81 running
31 one-79 running
Please note that VM 30 was deleted when we tried to delete VM 29. The /var/log/messages showed the following information:

Note that there is no IP address assigned to the br1 device which is used here. I don't think that should be a problem. Also the first 2 NICs are bonded first and then created as a bridge br0 and I don't think it is a problem either.

Has anyone had similar problem before? How can I fix it?
Thanks a lot.
