what permissions to use for Affinity Rules/Groups?
by Darrell Budic 03 Jan '22

I didn’t see any info in the Admin Guide for what permissions would allow users to setup Affinity Groups & Rules for the VMs they have access to. Anyone know what permissions are needed where to allow that? Thanks, -Darrell

Using IBM Spectrum Scale as POSIX compliant filesystem under oVirt 4.4 results in oVirt host reboot.
by Andi Nør Christiansen 03 Jan '22

Hi, Does anyone know how to mount a spectrum scale filesystem as a storage domain using the POSIX compliant storage option. I've tried to follow an earlier post about this - https://lists.ovirt.org/archives/list/users@ovirt.org/thread/LLXLSI4ZQFU32P… specifically the options provided by jtorres: Domain Function: Data Name: name_of_the_domain Storage Type: Posix Compliant FS Path: gpfs_kvm (the name of the "device"/"filesystem" created, not an absoluthe path) VFS Type: gpfs Mount Options: rw,relatime,dev=gpfs_kvm (the dev parameter is the key to mount the filesystem). Using those options, the webinterface just tells me it cannot communicate with the storage. If I change it to: Domain Function: Data Name: name_of_the_domain Storage Type: Posix Compliant FS Path: /mnt/b4tsz001 VFS Type: gpfs Mount Options: rw,relatime The oVirt host reboots immediately. I have mounted the filesystem locally on the oVirt Host under /mnt/<filesystem name> Change the owner to: vdsm:kvm Am I missing something or is this a general bug between spectrum scale and oVirt. Any ideas will be appreciated! Thanks Best Regards Andi Christiansen

Help installing oVirt on single machine, without cockpit

The reply button is taking me to a "mailto" tab again, but hopefully making the subject the same, will put this under the right thread? If not, I'm not sure how to reply on the new system. The original thread is here: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/3L6EVRT4YBEJOI…, and it continues here for a bit: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/C4Z65RXLFPOCS6… . @Strahil Nikolov > Have you thought about deploying HostedEngine and when you need to update the engine -> put the host in maintenance -> backup & restore The way I understand the update process, you can't update with a hosted engine unless you have two hosts. One needs to run the engine VM, so the other can go into maintenance. Is this wrong? For my use case, I'm looking for something that'll work/update on a single host. I'm trying to get the engine running next to the hypervisor, so it can run when the VM's come down. I can get the engine running on a CentOS Stream install, but it says it has 0/0 hosts running, so I don't think it can deploy VM's. I can't find a way to install the node's hypervisor package-set either. Unless that package exists, the only other idea I have for this route is doing a "hosted engine" install, but destroy the engine VM and point it to the local engine. This seems extreme to me lol. I tried setting up the engine on a node itself, but the error I can't get past yet is in the second url, top of this message. It can't start the ovirt-imageio service, because of a missing file. Happy Holidays all! Cameron

New OVIRT install fails
by Andy 01 Jan '22

01 Jan '22

Support/User List, Happy new year, I am trying a fresh install of ovirt (4.4.9) and cannot seem to get past deploying the host to the glusterfs volume. I am able to mount the volume from each host and have checked the configuration of the engine volume which allows vdsm and KVM to mount. I dont know if this is a glustermount problem or guestfish as the install fails when moving the VM to the hosted storage. Attached is the install log as well as the installed packaged. The specific error on install is: libguestfs: error: appliance closed the connection unexpectedly.\nThis usually means the libguestfs appliance crashed and the ansible setup fails at injecting network config with guestfish. The specific error form the install: fatal: [localhost]: FAILED! => {"changed": true, "cmd": ["guestfish", "-a", "/var/tmp/localvm4y8lnuwb/images/31647f4a-5dd8-4c24-9b36-82427e9f9d54/5445e40c-290f-4ea5-af25-9a86d3d72956", "--rw", "-i", "copy-in", "/var/tmp/localvm4y8lnuwb/ifcfg-eth0", "/etc/sysconfig/network-scripts", ":", "selinux-relabel", "/etc/selinux/targeted/contexts/files/file_contexts", "/etc/sysconfig/network-scripts/ifcfg-eth0", "force:true"], "delta": "0:00:03.911501", "end": "2021-12-31 20:51:38.551804", "msg": "non-zero return code", "rc": 1, "start": "2021-12-31 20:51:34.640303", "stderr": "libguestfs: error: appliance closed the connection unexpectedly.\nThis usually means the libguestfs appliance crashed.\nDo:\n export LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1\nand run the command again.

With libgfapi gone - ? - qcow2 backups
by lejeczek 31 Dec '21

31 Dec '21

hi guys Now with libgfapi support removed from qemu/libvirt - certainly in binaries from oVirt repos for CentOS 9 - how does one take qcow2 backups? Would that be some specific options to mount gluster vol in order to overcome: -> $ qemu-img convert -O qcow2 ./ubuntu.qcow2.bkp ubuntu.qcow2 qemu-img: Could not open './ubuntu-tor.qcow2.bkp': Could not open backing file: Failed to get shared "write" lock Is another process using the image [/VMs3/ubuntu.qcow2]? or perhaps 'qemu-img' can do the trick somehow? all thoughts shared are much appreciated. many thanks, L>
