Description Michal Skrivanek 2014-06-13 11:05:15 UTC

EL7 QEMU has this nice compression option to reduce the amount of data needed to be transferred during the live migration in certain workloads
let's use it!

some additional statistics should be added as part of bug 918410

Comment 2 Francesco Romani 2014-06-13 11:10:37 UTC

taking the bug

Comment 3 Scott Herold 2014-06-13 13:56:02 UTC

It looks like this has a dependency for RHEL 7 correct?

Comment 4 Michal Skrivanek 2014-06-13 14:02:07 UTC

yes. On the bright side on 7.0 and not 7.1 like most of the other things:-)

Comment 6 Israel Pinto 2015-10-07 15:05:48 UTC

Verify with version : 
RHEVM: 3.6 build: rhevm-3.6.0-0.18.master.el6.noarch
VDSM:vdsm-4.17.8-1.el7ev
libvirt: libvirt-1.2.17-5.el7

1. Performance test pass see comment 5
2. Functionality test check with last build (rhevm-3.6.0-0.18)
