oVirt console without disconnecting user
by Alex K 18 Sep '17

18 Sep '17

Hi All, When I get console of a Windows VM (Windows 10 x64bit) I am requested to authenticate and then the user is disconnected (though not logged out as the apps of the user are still open). I have tested this with QXL/SPICE and VGA/VNC console mode. Is there any mode at oVirt console to get console window at VM of user and in the same time allow the user to continue the session while me observing the user session, similar as when connecting with VNC? Thanx, Alex

PFSense VLAN Trunking
by LukeFlynn 18 Sep '17

18 Sep '17

Hello, I'm wondering if there is a way to trunk all VLANs to a PFSense VM similar to using the "4095" tag in ESXi. I've tried using an untagged interface on the same bond to no avail. Anyone have any ideas? Perhaps it's a problem with the virtio drivers and not the network setup itself? Thanks, Luke

[ANN] oVirt 4.1.6 Release is now available
by Sandro Bonazzola 18 Sep '17

18 Sep '17

The oVirt Project is pleased to announce the availability of oVirt 4.1.6 release, as of September 18th, 2017 This update is the sixth in a series of stabilization updates to the 4.1 series. 4.1.6 brings 23 enhancements and 100 bugfixes, including 53 high or urgent severity fixes, on top of oVirt 4.1 series Starting from 4.1.5 oVirt supports libgfapi [5]. Using libgfapi provides a real performance boost for ovirt when using GlusterFS . Due to a known issue [6], using this will break live storage migration. This is expected to be fixed soon. If you do not use live storage migration you can give it a try. Use [7] for more details on how to enable it. This release is available now for: * Red Hat Enterprise Linux 7.4 or later * CentOS Linux (or similar) 7.4 or later This release supports Hypervisor Hosts running: * Red Hat Enterprise Linux 7.4 or later * CentOS Linux (or similar) 7.4 or later * oVirt Node 4.1 See the release notes[3] for installation / upgrade instructions and a list of new features and bugs fixed. Notes: - oVirt Appliance is already available - oVirt Live and oVirt Node are not yet available, waiting for CentOS to publish qemu-kvm-ev 2.9.0 before composing ISOs based on CentOS 7.4. Will be published in [4] when ready.

gluster replica volumes with different data usage
by Alex K 17 Sep '17

17 Sep '17

Hi all, I have replica 3 with 1 arbiter. When checking the gluster volume bricks they are reported as using different space, as per attached. How come they use different space? One would expect to use exactly the same space since they are replica. Thanx, Alex

Ovirt HC engine will not start
by Jesper Andersson 17 Sep '17

17 Sep '17

Hi. I have a HC environment (oVirt 4.1.4) where the engine does not start. Tryed to update it to the latest oVirt but something happend on the storage side. Seemed like there was no data on the second node so we did a full heal, restarted the environment and now the ha-agent, broker and the engine does not start. "The hosted engine configuration has not been retrieved from shared storage. Please ensure that ovirt-ha-agent is running and the storage server is reachable." Tried to start the ha-agent but receives this error: ovirt-ha-agent ovirt_hosted_engine_ha.agent.agent.Agent ERROR Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/agent/agent.py", line 191, in _run_agent The broker wont start either: ovirt-ha-broker ovirt_hosted_engine_ha.broker.listener.ConnectionHandler ERROR Error handling request, data: 'set-storage-domain FilesystemBackend dom_type=glusterfs sd_uuid=2a79ea65-3df3-43cf-b1ba-304581f7918a' Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/ovirt... I'm not that experienced with ovirt nor gluster storage but gluster seems OK as far as I can see. Does anyone have an idea of how to resolve this? Please see attached logs.

Manual transfer of VMs from DC to DC
by Abi Askushi 17 Sep '17

17 Sep '17

Hi all, Is there any way of transferring VMs manually from DC to DC, without the DCs having connectivity with each other? I was thinking to backup all the export domain directory, and then later rsync this directory VMs to a new NFS share, then import this NFS share as an export domain on the other DC. What do you think? Thanx, Alex

engine randomly updated 1 package on all my hosts overnight
by Charles Kozler 17 Sep '17

17 Sep '17

I received an alert from OSSEC HIDS that a package was installed at 00:59. Nobody uses this infrastructure but me Upon investigation I find this Sep 14 00:59:18 ovirthost1 sshd[93263]: Accepted publickey for root from 10.0.16.50 port 50197 ssh2: RSA 1c:fc:0d:b8:40:2c:bf:87:f7:8f:b2:52:0b:c4:f6:4d Sep 14 00:59:18 ovirthost1 sshd[93263]: pam_unix(sshd:session): session opened for user root by (uid=0) Sep 14 00:59:46 ovirthost1 sshd[93263]: pam_unix(sshd:session): session closed for user root 10.0.16.50 is my ovirt engine And the yum log Sep 14 00:59:28 Updated: iproute-3.10.0-87.el7.x86_64 However, what is baffling to me is that this is a cluster I setup about 9 months ago and have not updated at all (its a testing env for VM systems) Why would ovirt seemingly randomly update and install a package? I know the engine checks for updates on hosts but this is the first time in my time using ovirt that ovirt instructed a host to install a package. This occurred on all of my ovirt nodes in this infrastructure (3) ovirt Version 4.0.1.1-1.el7.centos

Unable to resolve gluster hooks conflict
by Sherin George 17 Sep '17

17 Sep '17

Hello Guys, I am trying to fix an issue with "hooks conflict". Basically, I am seeing an exclamation mark for the hook "57glusterfind-delete-post.py" due to hooks conflict. I am seeing this in Ovirt >> Clusters >> GlusterStorage >> Gluster Hooks >> "57glusterfind-delete-post.py" When I started, the hook "57glusterfind-delete-post.py" was missing in some gluster hosts. So, I used "Resolve Conflicts" option and copied hooks in all gluster hosts. Now, I am able to see the hook in all gluster hosts and I am able to see same md5 sum for all hosts However, the exclamation mark for "57glusterfind-delete-post.py" is still there. When I examined each hook in "Resolve Content Conflict" option, I noticed that same code is shown for hook for all gluster hosts. However, the code is not shown when I check engine. Engine also shows same md5 sum as other gluster hosts. I tried to run "Resolve Conflicts" with "Resolve Content Conflict" option to copy the hook from a gluster host to others. However, the tool failed to see any content difference and it is giving me the error "Error while executing action: Cannot edit Gluster Hook. There are no conflicting servers to add or update hook." I think it is because same md5 sum is found for all. Any ideas or insights about a solution is much appreciated. SG

API auto delete vms snapshot
by Lionel Caignec 17 Sep '17

17 Sep '17

Hi, i'm playing with ovirt sdk, to automatically manage snapshots. My script is for now very basic step 1) list all vm of cluster step 2) for each vm create a snapshot if needed step 3) for each vm delete oldest snapshot No problem for step 1 and 2. But step 3 is harder. If i launch snap remove with command "snapshots_service.snapshot_service(snap.id).remove()", python tell me snapshot operation already in progress (creation of snapshot in step2). If i launch snap remove with parameter "async=true" the snapshot to delete is locked by ovirt, but never deleted. So how can i do? Also there is some way to monitor running task about snapshot (ovirt-shell ...)? -- Lionel
