Description SATHEESARAN 2018-09-24 12:30:11 UTC 
Description of problem:
-----------------------
Unable to migrate HE VM to other hosts in the cluster

Version-Release number of selected component (if applicable):
-------------------------------------------------------------
RHHI 2.0 - RHV 4.2.7 based on RHEL 7.6

How reproducible:
-----------------
Always

Steps to Reproduce:
-------------------
1. Create a Hosted Engine setup with 3 hosts, with hosted engine image storage on gluster 3 way replica
2. Create a separate logical network, configure the network role - as migration network and gluster
3. All the hosts are capable of running hosted engine. ( hosted-engine --deploy done from RHV Manager UI, while adding the host )
4. Migrate the HE VM to other host

Actual results:
----------------
HE VM fails to migrate

Expected results:
-----------------
HE VM should be capable of migrating to other hosts
Comment 1 SATHEESARAN 2018-09-25 11:02:16 UTC 
This looks like a libvirt issue - possible regression introduced from BZ 1494454  as suggested by  Simone
Comment 2 SATHEESARAN 2018-09-25 11:03:12 UTC 
This bug is not only affects HE VM also the any VMs running on gluster storage domain, hence updating the bug summary
Comment 7 SATHEESARAN 2018-10-17 02:15:00 UTC 
the dependent RHEL bug is already ON_QA, moving this bug to reflect the same
Comment 8 SATHEESARAN 2018-10-17 02:16:12 UTC 
Verified with libvirt-4.5.0-10.el7_6.2

The VMs could be live migrated from one virtualization RHEL 7.6 host to the other
