I am testing vm migration manually using virsh from one compute node to another:

---
nova@ccompute:~$ virsh   migrate  instance-0003457f0  qemu+ssh://<remote-ip>/system --live --verbose --unsafe
error: Unable to open file: /var/lib/nova/instances/f4d4r423r4d/console.log: No such file or directory


nova@ccompute:~$ ll /var/lib/nova/instances/f4d4r423r4d/
drwxr-xr-x  2 nova         nova      4096 Feb 17 15:43 ./
drwxr-xr-x 14 nova         nova      4096 Dec 16 22:31 ../
-rw-------  1 nova         root     56864 Feb 17 15:43 console.log
-rw-r--r--  1 libvirt-qemu kvm    1154624 Feb 17 15:35 disk
-rw-r--r--  1 nova         nova        79 Dec 16 22:30 disk.info
------
I am doing the above as 'nova' user.  Why is it failing even though it has r/w access to the console file ?

Thanks
