cannot stop vm normally
by Tommy Sway 15 Oct '21

15 Oct '21

Sometimes, some vm failed to stop it by press the shutdown button on the management portal, it will show such message in log: shutdown of vm *** failed. And I want to know: 1. why cannot shutdown it normally ? 2. what difference between the shutdown and power off ? (For example, what are the different signals sent to the QEMU process) Thanks.

How to add a note to a VM
by Gianluca Cecchi 12 Oct '21

12 Oct '21

Hello, I know there are the "Comment" and "Description" columns available in many areas of the Webadmin Gui. But there are some tasks, like "shutdown VM" or "Management -> Maintenance" for a host, where I can specify a "reason" for doing that task and then a note icon appears, aside the object, with the mouse over showing the note text, like in this image: https://drive.google.com/file/d/1v3Yd2t7AtuRFMT6HPFYYZqYUmJLMHYMY/view?usp=… Is there a way to do it in general? So for example I have a VM and I want to put a note (for some colleague, or to remind me to do an action tomorrow, ecc...) And btw: how can I manually remove the note? Eg I shutdown a VM and fill in the "Reason" field and then in a second moment I want to remove it.... Thanks in advance, Gianluca

Hey, I can't get the artifacts to cleanup, i have configured the ansible runner config.yml but it seems not to be running. Should i restart the ovirt-engine service? What is the best way to manually cleanup the artifacts (i can't get the correct ansible-runner command to clean it up) as it is starting to fill up disk space Thanks

Re: fresh hyperconverged Gluster setup failed in ovirt 4.4.8
by Ax Olmos 11 Oct '21

11 Oct '21

The problem is that the ‘glusterd_brick_t’ file context is missing from selinux-policy-targeted 3.14.3-80 on CentOS 8 Stream. It exists in the CentOS 8.4 version: rpm -qpl selinux-policy-targeted-3.14.3-67.el8_4.2.noarch.rpm | grep gluster /usr/share/selinux/targeted/default/active/modules/100/glusterd /usr/share/selinux/targeted/default/active/modules/100/glusterd/cil /usr/share/selinux/targeted/default/active/modules/100/glusterd/lang_ext /var/lib/selinux/targeted/active/modules/100/glusterd /var/lib/selinux/targeted/active/modules/100/glusterd/cil /var/lib/selinux/targeted/active/modules/100/glusterd/hll /var/lib/selinux/targeted/active/modules/100/glusterd/lang_ext Not on CentOS 8 Stream: rpm -qpl selinux-policy-targeted-3.14.3-80.el8.noarch.rpm | grep gluster You can remove the selinux checks from: /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/mount.yml but I’m not sure of the implications of that. This is a show stopper for oVirt and someone from oVirt needs to contact the CentOS 8 Stream maintainers and have them put the selinux context back, or come up with some other workaround.

Slow gluster replication
by David White 11 Oct '21

11 Oct '21

I can't remember if I've asked this already, or if someone else has brought this up. I have noticed that gluster replication in a hyperconverged environment is very slow. I just (successfully, this time) added a brick to volume that was originally built on a single-node Hyperconverged cluster. One of my volumes has over 600GB, but the network is 10Gbps, so replication really shouldn't take that long. It's been over two hours, and that volume has only replicated a little over 400GB. It feels like it's taking about 1GB every 30 seconds - 1 minute or so... Why would this replication be so slow? Sent with ProtonMail Secure Email.
