Rohit Yadav commented on CLOUDSTACK-118:
----------------------------------------

@Prashant, this a very special case and most likely your storage or KVM 
configuration. I tried to read through the logs but was unable to diagnose the 
problem. As you suggest this bug may not be caught everytime, it is may be 
time/thread/sync issue.

For KVM, how are disk names set? I see it fails while trying to set uid/gid 
over a file that does not exist, and has internal name with patchdisk suffix, 
instead of uuid/guid which is the case for Xen.

2012-10-05 12:27:35,585 ERROR [cloud.vm.VirtualMachineManagerImpl] 
(HA-Worker-0:work-5) Unable to migrate due to unable to set user and group to 
'0:0' on '/mnt/6e8264c6-4591-399b-b4b0-123f61342208/s-1-VM-patchdisk': No such 
file or directory

@Sudha: can anyone in BLR/SC be assigned to verify this bug?
Triaging to Edison or anyone on KVM.

Thanks.
