[QE] oVirt 3.5.2 status
by Sandro Bonazzola 28 Jan '15

28 Jan '15

Hi, Development cycle for oVirt 3.5.2 release started and we're now going to schedule this release. A release management entry has been added for tracking the schedule of 3.5.2 [0] A bug tracker [1] has been created and currently has no open blockers. Maintainers: - Please be sure that 3.5 snapshot allow to create VMs - Please be sure that no pending patches are going to block the release - If any patch must block the RC release please raise the issue as soon as possible. There are still 44 bugs [2] targeted to 3.5.2. Excluding node and documentation bugs we still have 36 bugs [3] targeted to 3.5.2. Maintainers / Assignee: - Please add the bugs to the tracker if you think that 3.5.2 should not be released without them fixed. - Please update the target to 3.5.3 or later for bugs that won't be in 3.5.2: it will ease gathering the blocking bugs for next releases. - Please fill release notes, the page has been created here [4] Community: - If you're testing oVirt 3.5 nightly snapshot, please add yourself to the test page [5] [0] http://www.ovirt.org/OVirt_3.5.z_Release_Management#oVirt_3.5.2 [1] http://bugzilla.redhat.com/1186161 [2] http://goo.gl/crVJPH [3]http://goo.gl/2qTZZU [4] http://www.ovirt.org/OVirt_3.5.2_Release_Notes [5] http://www.ovirt.org/Testing/oVirt_3.5.2_Testing -- Sandro Bonazzola Better technology.

I'm on the same.. And I see the issue. Why don't you create a new network with the correct parameters and then move the network the VM is attached to On Jan 27, 2015 1:39 PM, Darrell Budic <budic(a)onholyground.com> wrote: > > Try changing that custom MTU and hitting OK.

Changing the engine HA ping address?
by Chris Adams 27 Jan '15

27 Jan '15

I have an up-to-date hosted-engine 3.5.1 setup (CentOS 7 for the nodes, CentOS 6 for the engine), and the engine keeps jumping between the two nodes running the hosted-engine HA (sometimes after just 10-20 minutes, sometimes after a day or two). I figured out that it is failing on pinging the gateway sometimes. The gateway IP is a layer-3 switch, and I think sometimes it just is not responding to ICMP echo request in a timely fashion (traffic is routing just fine though). How is the HA ping implemented? How many requests does it send (and how many responses are required to be considered "good")? If I can't tweak the sensitivity of the ping, I'd like to ping a different IP (on a HA load balancer setup). The oVirt HA config refers to it as "gateway" though; is it really used as a gateway in any case, or is that just the recommended IP? Can I just edit /etc/ovirt-hosted-engine/hosted-engine.conf on the two nodes and restart the ovirt-ha-broker service? -- Chris Adams <cma(a)cmadams.net>

Except you can’t change the network MTU setting in the first place on the network in the GUI. I’ve thought about doing it in the database, with a migration as you mention.

Network config
by Koen Vanoppen 27 Jan '15

27 Jan '15

Hello everybody, Just wanted to know if anybody else has the problem, that when you restart your network configuration of a hypervisor, all the settings concerning the bonding are gone... Do I file a bug report for this or is this already a known issue? Kind regards, Koen
