VM templates
by Robert Tongue 25 Jan '21

25 Jan '21

Hello, Another weird issue over here. I have the latest oVirt running inside VMware Vcenter, as a proof of concept/testing platform. Things are working well finally, for the most part, however I am noticing strange behavior with templates, and deployed VMs from that template. Let me explain: I created a basic Ubuntu Server VM, captured that VM as a template, then deployed 4 VMs from that template. The deployment went fine; however I can only start 3 of the 4 VMs. If I shut one down one of the 3 that I started, I can then start the other one that refused to start, then the one I JUST shut down will then refuse to start. The error is: VM test3 is down with error. Exit message: Bad volume specification {'device': 'disk', 'type': 'disk', 'diskType': 'file', 'specParams': {}, 'alias': 'ua-2dc7fbff-da30-485d-891f-03a0ed60fd0a', 'address': {'bus': '0', 'controller': '0', 'unit': '0', 'type': 'drive', 'target': '0'}, 'domainID': '804c6a0c-b246-4ccc-b3ab-dd4ceb819cea', 'imageID': '2dc7fbff-da30-485d-891f-03a0ed60fd0a', 'poolID': '3208bbce-5e04-11eb-9313-00163e281c6d', 'volumeID': 'f514ab22-07ae-40e4-9146-1041d78553fd', 'path': '/rhev/data-center/3208bbce-5e04-11eb-9313-00163e281c6d/804c6a0c-b246-4ccc-b3ab-dd4ceb819cea/images/2dc7fbff-da30-485d-891f-03a0ed60fd0a/f514ab22-07ae-40e4-9146-1041d78553fd', 'discard': True, 'format': 'cow', 'propagateErrors': 'off', 'cache': 'none', 'iface': 'scsi', 'name': 'sda', 'bootOrder': '1', 'serial': '2dc7fbff-da30-485d-891f-03a0ed60fd0a', 'index': 0, 'reqsize': '0', 'truesize': '2882392576', 'apparentsize': '3435134976'}. The underlying storage is GlusterFS, self-managed outside of oVirt. I can provide any logs needed, please let me know which. Thanks in advance.

split brain scenario?
by Henry lol 24 Jan '21

24 Jan '21

Hi, according to HA VM documentation, a paused VM may be started on another host and later resumed on the original host. - https://www.ovirt.org/develop/ha-vms.html here, I'm assuming the HA VM was paused due to I/O error. but I'm wondering how it can happen because I guess the HA VM will be restarted on another host only after it's completely killed from the original host. can you give the split brain scenario?

Hello All, I'm really worried about the following news: https://blog.centos.org/2020/12/future-is-centos-stream/ Did anyone tried to port oVirt to SLES/openSUSE or any Debian-based distro ? Best Regards, Strahil Nikolov

Re: VMware Fence Agent
by Strahil Nikolov 23 Jan '21

I think it's easier to get the Vmware's CA certificate and import it on all hosts + engine and trust it.By default you should put it at /etc/pki/ca-trust/source/anchors/ and then use "update-ca-trust" to make all certs signed by the Vmware vCenter's CA trusted.
