Open Stack

Hello,

While most of the instances are running fine in my openstack cluster, 
but there are few that are stuck in either build, networking or 
scheduling state, and can't even be deleted.
On the compute nodes, I see in the log:

2012-10-11 10:26:46 WARNING nova.compute.manager [-] Found 5 in the 
database and 1 on the hypervisor.
2012-10-11 10:26:47 WARNING nova.compute.manager [-] [instance: 
da5106f4-deb2-4827-952e-7cb19388ea8d] Instance found in database but not 
known by hypervisor. Setting power state to NOSTATE
2012-10-11 10:26:47 WARNING nova.compute.manager [-] [instance:

known by hypervisor. Setting power state to NOSTATE
2012-10-11 10:26:48 WARNING nova.compute.manager [-] [instance: 
92febd69-ddc4-489f-8120-1b272d788856] Instance found in database but not 
known by hypervisor. Setting power state to NOSTATE
2012-10-11 10:26:48 WARNING nova.compute.manager [-] [instance: 
3ff3bd7c-87ef-4425-83c3-d27103c52ee0] Instance found in database but not 
known by hypervisor. Setting power state to NOSTATE

Any wisdom what is happening here?

Thanks,
Xin
