hi all,

prob1:
I deployed openstack on a 1controller+Ncompute basis. All the compute node
seems work well and windows 2008 server image can be spawned successfully,
except on one compute node, I encountered the following errors, can someone
tell me what might be the problem??
after deleting all the files under "_base" dir, the error still there.
if needed, further info can be provided

prob2:
since the problem may be on the fact that the cached image on the compute
node is broken, so how to force the compute node to abandon its local
cached images and get from the remote image server???
simply deleting all the files under "_base" dir seems don't work, I see no
data transfer between the compute node and the image server.

thks in advance!
