Description of problem:

while I had ISO domain attached to my Data Center, I ran a VM. 
The rhevm-tools cd is attached automatically to the VM if tools are not already installed and if you have an ISO domain attached. 
While the VM was up I detached the ISO domain and tried to migrate the vm. 
migration failes with error: 

libvirtError: internal error process exited while connecting to monitor: qemu-kvm: -drive file=/rhev/data-center/85f41813-ab57-419c-b05c-f4ccb9f8fa27/771adde0-5939-4543-bdc6-0b1

Comment 2 Dan Kenigsberg 2011-09-18 15:59:35 UTC 
Dafna, I am afraid this is a known issue. Unlike RHEV-2.2, 3.0 uses libvirt which fails migration if the destination cannot see the CD image (bug 725673). You would have to eject the CD before migration.
