[ovirt-users] Two Problems On New Install

Hi Martin,

   Thanks for responding, and sorry for the long delay in getting back 
to you.  Where would I find the libvirt log?  I checked on the host and 
I have individual log files in /var/log/libvirt/qemu/<vmName>.log, but 
nothing for the guest I'm trying to migrate.

   I did some more digging and found these errors, which seem to point 
to some sort of issue communicating with the JsonRpcServer module.  I've 
put the full vdsm.log output from the migration attempt up at 
http://krissy.islandadmin.ca/public/vdsm.txt but the interesting parts 
seems to be:
