Hi all~

I have four physical servers and there is nova modules.

First node: nova-api,nova-objectstore,nova-scheduler,glance IP:10.250.0.1 Second node: nova-network IP:10.250.0.2 Third node: nova-compute IP:10.250.0.3 Fourth node: nova-volume IP:10.250.0.4

The problem is when I start run up a new instance, the Third node can`t get images from First node.

In Third node /var/lib/nova/instances/_base, there is only 0 byte file that name is 00000001.

drwxr-xr-x 2 nova nogroup 4096 2011-06-18 23:13 ./ drwxr-xr-x 5 nova root 4096 2011-06-18 23:13 ../

-rw-r--r-- 1 nova nogroup 0 2011-06-18 23:13 00000001

Here is Third node nova-compute.log
