HI， I create a HA VM in ovirt follaw this article https://ovirt.org/develop/ha-vms.html#highly-available-vms-and-io-errors when my vm‘s OS can not run, but ovirt consider this vm is up, so is this a bug for HA VM? can you give me some advise? Regards Hongyu Du

Ovirt Nested in VMWare (Working approach)
by RabidCicada 30 Apr '19

30 Apr '19

I worked through this previously and posted in IRC yesterday about working around running ovirt nested under VMWare. I figured i'd post it to the mail group so that it would be available in it's entirety here for future reference: The following gists explain the 3 major adjustments that have to be made currently to get nested virt under vmware working: https://gist.github.com/RabidCicada/993349b3a7eaf35637122f0122fdedb3 https://gist.github.com/RabidCicada/bc01eb0b13195faa26520c0fb666ec34 https://gist.github.com/RabidCicada/37ff6f1ed2afd8dd4edefac735536c69 https://gist.github.com/RabidCicada/40655db1582ca5d07c9bbf2c429cdd01 Hopefully it can save others the huge amount of time it took me to figure it all out. Specifically it's a problem with the --machine type at 3 major parts of the vm creation for the hosted-engine. 1) You have to fix the virt-install to use --machine pc-i440fx-rhel7.2.0 2) You have to fix the guestfish spinup of the partially configured vm to use --machine pc-i440fx-rhel7.2.0, where they edit the nic config among other things 3) You have to tell vdsm on the node to use --machine pc-i440fx-rhel7.2.0 I don't know the underlying reason why a --machine type > pc-i440fx-rhel7.2.0 breaks the system but it ends up resulting in a bios freeze. Again, Hope this helps someone. Suggested only to use for a test/dev system.

[QA][Feedback Needed] RDO Stein integration testing
by Sandro Bonazzola 30 Apr '19

30 Apr '19

Hi, RDO Stein has been released a few days ago: https://blogs.rdoproject.org/2019/04/rdo-stein-released/ I opened test bug for the providers oVirt is consuming from OpenStack: Neutron, Glance and Cinder. Has anyone capacity for testing this (not on production systems!) and give feedback?

ovirt 4.3.3 cannot create VM in non-default cluster
by Strahil Nikolov 29 Apr '19

29 Apr '19

Hi All, I'm having an issue to create a VM in my second cluster called "Intel" which consists of only 1 Host -> ovirt3 which plays the role of a gluster arbiter in my hyperconverged setup. When I try to create the VM (via UI) I receive: "Cannot add VM. CPU Profile doesn't match provided Cluster." When I try to select the host where I can put the VM , I see only ovirt1 or ovirt2 which are part of the 'Default' Cluster . Do we have an opened bug for that ? Note: A workaround is to create the VM in the Default cluster and later edit it to match the needed Cluster. Best Regards,Strahil Nikolov

Upgraded ovirt-4.2 to ovirt-4.3 and VM run fails
by Gobinda Das 29 Apr '19

29 Apr '19

Hi, I have upgraded ovirt-4.2 to ovirt-4.3 and after upgrade while starting vms giving me error: Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details: The host *node1.test.com <http://node1.test.com>* did not satisfy internal filter ClusterInMaintenance because the cluster is in maintenance and only highly available VMs are allowed to start. The host *node2.test.com <http://node2.test.com>* did not satisfy internal filter ClusterInMaintenance because the cluster is in maintenance and only highly available VMs are allowed to start. The host *node3.test.com <http://node3.test.com>* did not satisfy internal filter ClusterInMaintenance because the cluster is in maintenance and only highly available VMs are allowed to start. Eventhough cluster is not in maintenance mode. This setup is using gluster6 for storage. -- Thanks, Gobinda

HA VMs fail to start on host failure
by tezmobile＠googlemail.com 29 Apr '19

29 Apr '19

In a host failure situation, we see that oVirt tries to restart the VMs on other hosts in the cluster but this (more often than not) fails due to kvm being unable to acquire a write lock on the qcow2 image. We see ovirt attempt to restart the VMs several times, each time on different hosts but with the same outcome after which it gives up trying. After this we must log into the oVirt web interface and start the VM manually, which works fine (by this time we assume enough time has passed for the lock to clear itself). This behaviour is experienced with Centos 7.6, Libvirt 4.5.0-10, vdsm 4.30.13-1 Log excerpt from hosted engine: 2019-04-24 17:05:26,653+01 INFO [org.ovirt.engine.core.vdsbroker.monitoring.VmAnalyzer] (EE-ManagedThreadFactory-engineScheduled-Thread-82) [] VM 'ef7e04f0-764a-4cfe-96bf-c0862f1f5b83'(vm-21.example.local) moved from 'WaitForLaunch' --> 'Down' 2019-04-24 17:05:26,710+01 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-82) [] EVENT_ID: VM_DOWN_ERROR(119), VM vm-21.example.local is down with error.

Template Disk Corruption
by Alex McWhirter 29 Apr '19

29 Apr '19

1. Create server template from server VM (so it's a full copy of the disk) 2. From template create a VM, override server to desktop, so that it become a qcow2 overlay to the template raw disk. 3. Boot VM 4. Shutdown VM 5. Delete VM Template disk is now corrupt, any new machines made from it will not boot. I can't see why this happens as the desktop optimized VM should have just been an overlay qcow file...
