VM pools broken in 4.3
by Rik Theys 21 May '19

21 May '19

Hi, It seems VM pools are completely broken since our upgrade to 4.3. Is anybody else also experiencing this issue? Only a single instance from a pool can be used. Afterwards the pool becomes unusable due to a lock not being released. Once ovirt-engine is restarted, another (single) VM from a pool can be used. I've added my findings to bug 1462236, but I'm no longer sure the issue is the same as the one initially reported. When the first VM of a pool is started: 2019-05-14 13:26:46,058+02 INFO [org.ovirt.engine.core.vdsbroker.IsVmDuringInitiatingVDSCommand] (default task-6) [e3c5745c-e593-4aed-ba67-b173808140e8] START, IsVmDuringInitiatingVDSCommand( IsVmDuringInitiatingVDSCommandParameters:{vmId='d8a99676-d520-425e-9974-1b1efe6da8a5'}), log id: 2fb4f7f5 2019-05-14 13:26:46,058+02 INFO [org.ovirt.engine.core.vdsbroker.IsVmDuringInitiatingVDSCommand] (default task-6) [e3c5745c-e593-4aed-ba67-b173808140e8] FINISH, IsVmDuringInitiatingVDSCommand, return: false, log id: 2fb4f7f5 2019-05-14 13:26:46,208+02 INFO [org.ovirt.engine.core.bll.VmPoolHandler] (default task-6) [e3c5745c-e593-4aed-ba67-b173808140e8] Lock Acquired to object 'EngineLock:{exclusiveLocks='[d8a99676-d520-425e-9974-1b1efe6da8a5=VM]', sharedLocks=''}' -> it has acquired a lock (lock1) 2019-05-14 13:26:46,247+02 INFO [org.ovirt.engine.core.bll.AttachUserToVmFromPoolAndRunCommand] (default task-6) [e3c5745c-e593-4aed-ba67-b173808140e8] Lock Acquired to object 'EngineLock:{exclusiveLocks='[a5bed59c-d2fe-4fe4-bff7-52efe089ebd6=USER_VM_POOL]', sharedLocks=''}' -> it has acquired another lock (lock2) 2019-05-14 13:26:46,352+02 INFO [org.ovirt.engine.core.bll.AttachUserToVmFromPoolAndRunCommand] (default task-6) [e3c5745c-e593-4aed-ba67-b173808140e8] Running command: AttachUserToVmFromPoolAndRunCommand internal: false.

On this one https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.3/h… We should have the following options: performance.quick-read=off performance.read-ahead=off performance.io-cache=off performance.stat-prefetch=off performance.low-prio-threads=32 network.remote-dio=enable cluster.eager-lock=enable cluster.quorum-type=auto cluster.server-quorum-type=server cluster.data-self-heal-algorithm=full cluster.locking-scheme=granular cluster.shd-max-threads=8 cluster.shd-wait-qlength=10000 features.shard=on user.cifs=off By the way the 'virt' gluster group disables 'cluster.choose-local' and I think it wasn't like that. Any reasons behind that , as I use it to speedup my reads, as local storage is faster than the network?

I was able to create the new gluster volume fine, but it’s not able to add the gluster storage domain (as either a managed gluster volume or directly entering values). The created gluster volume mounts and looks fine from the CLI.

Re: [ANN] oVirt 4.3.4 First Release Candidate is now available
by Strahil 21 May '19

Hi Sandro, Thanks for the update. I have just upgraded to RC1 (using gluster v6 here) and the issue I detected in 4.3.3.7 - where gluster Storage domain fails creation - is still present. Can you check if the 'dd' command executed during creation has been recently modified ? I've received update from Darrell (also gluster v6) , but haven't received an update from anyone who is using gluster v5 -> thus I haven't opened a bug yet.

Virtual office, how?
by andres.b.dev＠gmail.com 21 May '19

21 May '19

I'm trying to be able to create different virtual LANs, where, for example, I have 2 groups of pcs A and B belongs to network N1 C and D belongs to network N2 N1 and N2 with his own public IP. For example A: Local ip: 192.168.122.100 B: Local ip: 192.168.122.101 C: Local ip: 192.168.122.102 D: Local ip: 192.168.122.103 Where A and B has the same public ip, and C and D has the same public ip. Now, I want that A can ssh on B, but not on C or D. The same goes for C, where C can access to D via ssh but not to A or B I'm not sure if OVS solve this problem or not, or if this is not possible. Is this possible? How?

Every now and then Backup question
by Markus Schaufler 21 May '19

21 May '19

Hi, looking for a backup solution compareable to vmware/veeam - ie. features like agent-less, incremental, lan-free backups with dedup and single item restore. As I understand the main construction site for all commercial backup solutions available for kvm/rhev was the underlying qemu with its CBT implementation. The main functions should now be implemented as there are solutions like vprotect which state that they support incremental backups for rhev. But as I read at https://www.openvirtualization.pro/agent-less-backup-strategies-for-ovirt-r… there might still be some drawbacks. Are there ressources or a roadmap covering the state of the backup/recovery process, ie. what is possible now and whats in progress? I'm sure a big showstopper for open source virtualization projects are is uncertainty about backup/recovery and especially disaster recovery processes. Follow up questions to the users with bigger environments: Whats your current backup and DR strategy? Does anybody have experience with commercially availbe backup solutions like Bacula, SEP, Commvault, etc.?

newbie questions about installation using synology NAS
by bmillett＠gmail.com 20 May '19

20 May '19

I'm starting fairly fresh. Ovirt engine 4.3.3.7 on a host 2 nodes installed with ovirt-release-host-node-4.3.3.1 synology DS418 with 5 TB disks I've configured the master engine and am ready to add the nodes. My questions have to do with the order or steps . Do I need to mount /volume1/data/images/rhev from the DS418 on each of the nodes before I add them or do I just add the nodes, then define a domain using the NFS mounts from the DS418? Thanks.

Define the nodes and when you create your NFS storage domain - it will be automatically mounted on all hosts in the DC.

Re: oVirt upgrade version from 4.2 to 4.3

I would recommend you to postpone your upgrade if you use gluster (without the API) , as creation of virtual disks via UI on gluster is having issues - only preallocated can be created.
