Engine High Availability
by Sunny Shin 06 Mar '16

06 Mar '16

Hi All, In the new architecture page ( http://www.ovirt.org/documentation/architecture/architecture/) overall architecture picture shows that engine supports active-active high availability. However, as per engine HA page ( http://www.ovirt.org/develop/release-management/features/engine/engine-high…) active-active HA is not supported yet and there are several implementation issues. So, could anyone give me a brief explanation about discrepancy between these two pages, and about the plan to implement this feature if not implemented yet? Sunny

Allow access to Cockpit by default after adding a host? Or make it configurable in Engine?
by Fabian Deutsch 04 Mar '16

04 Mar '16

Hey, Node Next will ship Cockpit by default. When the host is getting installed, Cockpit can be reached by default over it's port 9090/tcp. But after the host was added to Engine, Engine/vdsm is setting up it's own iptables rules which then prevent further access to Cockpit. How do we want users to control the access to Cockpit? So where shall users be able to open or close the Cockpit firewall port. Initially I thought that we can open up the cockpit port by default, but this might be a security issue. (Brute force attacks to crack user passwords through the web interface). - fabian

oVirt Engine 3.6.4 branch was created + backport guide for 3.6.z
by Tal Nisan 03 Mar '16

03 Mar '16

Hi everyone, The ovirt-engine-3.6.4 branch has been created following the last (hopefully) respin of 3.6.3 Note the the branch was created from the 3.6.3 branch today and contains all the content of 3.6.3 obviously. As I am asked a lot of questions questions concerning the backport flow for 3.6.z bugs, here it is: 3.6.5 bugs should be included in: - master - ovirt-engine-3.6 3.6.4 bugs should be included in: - master - ovirt-engine-3.6 - ovirt-engine-3.6.4. As for 3.6.6 only bugs i.e. those that are solved in the timeline before branching out of 3.6.5 but you do not want them to be included in 3.6.5, those should NOT be merged on ovirt-engine-3.6 until 3.6.5 will be branched out (date TBD, probably a couple of weeks before the release date). For further questions feel free to contact me.

[ACTION REQUIRED] Legacy code removal
by Sandro Bonazzola 03 Mar '16

03 Mar '16

Hi, for oVirt 4.0 we're going to drop backward compatibility with oVirt < 3.6, you're kindly invited to cleanup the code dropping legacy support for older version. More in detail, for 4.0 we'll assume: * Support for EL6 hosts will be dropped * oVirt Engine support for EL6 will be dropped * Upgrade / Migration (if oVirt Engine was running on EL6) will be supported only from oVirt 3.6 * Network API support for oVirt < 3.6 will be dropped, the remaining API should be backward compatible * oVirt Engine will support cluster compatibility >= 3.6 * We won't support in place upgrade for oVirt Engine from 3.6 EL6 to 4.0 EL7: we'll support only migration. * oVirt DWH will only have 3.6 \ 4.0 compatibility views in 4.0. Thanks, -- Sandro Bonazzola Better technology. Faster innovation. Powered by community collaboration. See how it works at redhat.com

Cockpit port open by default after adding host
by Fabian Deutsch 02 Mar '16

02 Mar '16

Hey, we use cockpit on Node Next, and we configure firewalld to open the port by default. However, after adding the host to Engine, the port is getting closed again because iptables is the used. How do you recommend to get the cockpit port opened by default? - fabian

Move host-deploy package installations into package?
by Fabian Deutsch 02 Mar '16

02 Mar '16

Hey, IIUIC host-deploy is currently installing some packages manually: https://gerrit.ovirt.org/gitweb?p=ovirt-host-deploy.git;a=blob;f=src/plugin… Can't these dependencies moved to vdsm - or if not - can't they be moved to a ovirt-host package? Then we'd have all package related informations in one place. I find it odd that host-deploy is taking care of package installation, imo it should be sufficient to install a single package and have a host ready. host-deploy can then focus on just configuring the existing packages. Thoughts? - fabian

Iscsi and other BAD buggy
by Вячеслав Бадалян 02 Mar '16

02 Mar '16

Hello. ZERO) https://bugzilla.redhat.com/enter_bug.cgi?product=ovirt Sorry, entering a bug into the product *oVirt* has been disabled And lets go. A) If host with ovirt have iscsi target we will have bug troubles. Its looks like 1. Create targetcli from LVM 2. All ok 3. Reboot 4/ LVM found oVIrt partitions and connect it. 5. targetcli can't get device. It's allready busy. If you add some filter to don's search iscsi devices then ovirt does not work correctly. B) Some throuble with glusterD. VSDM do mount of hosted engine volume and this host is aslo GluserD Server. Bug troubles. C) If i reboot 1 of 3 gluster servers then hosted engine will very slowly. Have many errors in dmes, Agent-ha reboot VM. Vm can't conect to don't full cluster and stuck in Paused mode. Realy... Its all look so bad... i mirgrate to NFS :( D) Network conffugurate realy bad. If i need to change network i can't do it. oVirt save posted from web settings. Bug vsdm-networking MUST fallback to previos setup if i mistake or SERVIS does not start. E). Ovirt reports does not install.
