[one-users] Migration problem

Thu Mar 17 12:42:26 PDT 2011

Seems I have missed some key detail, when I attempt to migrate a vm it fails.

I can run a vm on the other host with libvirt / virt manager fine.

Any ideas come to mind or a suggestion on where to look?

Before attempted migration the image was owned by oneadmin:cloud
The image file becomes owned by root
s -l /var/lib/one/images/229ec3e88658934ce75dac63633b83a60ac48cf2 
-rw-rw---- 1 root root 8589934592 Mar 17 15:08 /var/lib/one/images/229ec3e88658934ce75dac63633b83a60ac48cf2

The VM log file shows
