Dear all,
we ahve a setup with several hosts running fedora 10 with the virt-preview packages installed (for snapshot live merge) and a hosted engine running centos 6.6-
We are experiencing a problem with the Live Migration of the Hosted Engine, in the case of setting the host for the Engine into maintenance as well as a manual migration.
I tried this on the ovirtmgmt network and when that failed I did some research and tried to use another network interface (separate from ovirtmgmt on layer 2), this also fails.
It looks as if the migration is still going through the ovirtmgmt interface, at least judging from the network traffic, and I think the error that I found (RHBZ#919201) is actually the right one.

The ovirtmgmt interface is 2 x 1Gbit (LACP connected to Dell Switches with MLAG) and by far not fully utilized.
Can anyone help me where to go form here ?
still need the whole log. probably the guest (engine) is doing lots of memory i/o if you got a fair amount of running VMs and Hosts. that will stalls the migration because the guest pages are getting dirty faster than qemu can copy. you have 2 options: 1. try several more times. 2. shutdown the engine vm, it should start on another host
