Re: [ovirt-users] Where do you run oVirt? Here are the answers!
very nice! great to see the distribution of OSs, can give us a hint on where to focus testing/ci/etc... e. - Original Message - From: Sandro Bonazzola sbona...@redhat.com To: de...@ovirt.org, Users@ovirt.org Sent: Tuesday, March 3, 2015 1:56:30 PM Subject: [ovirt-users] Where do you run oVirt?
