Questions and Suggestions for oVirt
by Daniel Gurgel 30 Jan '25

30 Jan '25

With the new leadership of the project, most users who admire and support oVirt would like to know the roadmap and future plans. From my perspective, I understand that Red Hat discontinued its support purely for financial reasons. Therefore, this is probably one of the key areas where oVirt needs to strengthen. Wouldn't it be worth seeking support and collaboration with Veeam and Oracle, given its "OLVM"? Especially considering that, after the VMware/Broadcom licensing changes, Oracle has been aggressively offering OLVM to customers as a migration alternative. A positive development was Veeam Backup & Replication recently adding support for OLVM. This has increased interest in the solution, but there are still limitations, such as migration/backup/restore between different hypervisors (interestingly, this feature is available for Proxmox/KVM, which uses similar technology). These are some of the main questions from customers: 1. When will it be updated to Enterprise Linux 9 or 10? 2. What support will be available for new technologies? 3. How about a change in the Engine/Manager, allowing VMs to be managed even when the Engine is unavailable! (Sorry, but this is one of oVirt's biggest bottlenecks, and inevitably, comparisons with VMware/VCenter arise.) 4. Support for VM migration between Datacenters should also be carefully considered. **Note**: The oVirt website needs to be more user-friendly for general users. I also suggest a fundraising campaign—I would be happy to contribute, and I believe the entire user base would as well!

Re: [EXT]Re: Re: [SOLVED] Re: Re: How to re-enroll (or renew) host certificates for a single-host hosted-engine deployment?

I have checked the solution and it works, apart from the console feature of the virtual machine. In my case, once a got control over the host, migrated all the vms and then Maintenance and then Enroll Certificate. So: an updated version ``` set -x ## Make the script echo everything out, so if it fails you know where set -e ## Make the script STOP on any error set my_date="$(date +"%Y%m%d%H%M%S")" # Backup the existing CA files /bin/cp -p /etc/pki/ovirt-engine/private/ca.pem /etc/pki/ovirt-engine/private/ca.pem.$my_date /bin/cp -p /etc/pki/ovirt-engine/ca.pem{,.$my_date} /bin/mv /etc/pki/ovirt-engine/certs/ca.der{,.$my_date} # Sign the key openssl x509 -signkey /etc/pki/ovirt-engine/private/ca.pem -in /etc/pki/ovirt-engine/ca.pem -out /etc/pki/ovirt-engine/ca.pem.new -days 3650 -sha256 openssl x509 -in /etc/pki/ovirt-engine/ca.pem.new -text > /etc/pki/ovirt-engine/ca.pem.new.full # Put the files into place /bin/mv -f /etc/pki/ovirt-engine/ca.pem.new.full /etc/pki/ovirt-engine/ca.pem /bin/cp -p /etc/pki/ovirt-engine/ca.pem.new /etc/pki/ovirt-engine/certs/ca.der ``` Now you need to copy the new CA file over to the host: Source: ENGINE `/etc/pki/ovirt-engine/ca.pem` Dest: HOST `/tmp/new-ca.pem` ########### On the oVirt Host ########### # Create a CSR using the information from the existing certificate and the existing key: openssl x509 -x509toreq -in /etc/pki/libvirt/clientcert.pem -out /tmp/HOST.csr -signkey /etc/pki/libvirt/private/clientkey.pem Now you need to copy the new CA file over to the host: Source: HOST `/tmp/HOST.csr` Dest: ENGINE `/etc/pki/ovirt-engine/requests/full.hostname.com.req` ########### On the ENGINE HOST ########### # Now sign it: /usr/share/ovirt-engine/bin/pki-enroll-request.sh --name=full.hostname.com # NB -- adding --san results in an error: --san=host.na.me (So no Subject Alternate Names) Now you need to copy the new Certificate file over to the host: Source: ENGINE /etc/pki/ovirt-engine/certs/full.hostname.com.cer Dest: HOST /tmp/new-cert.pem ########### On the oVirt Host ########### (see bellow the written script) #!/bin/bash #set -x set -e mydate="$(date +"%Y%m%d%H%M%S")" echo "[.] reference ${mydate}" for x in /tmp/new-ca.pem /tmp/new-cert.pem ; do echo -n "[.] checking $x" if [ ! -e "$x" ]; then echo "[not found]" exit else echo "[found]" fi done for x in /etc/pki/libvirt/clientcert.pem /etc/pki/vdsm/certs/vdsmcert.pem /etc/pki/vdsm/libvirt-migrate/server-cert.pem /etc/pki/vdsm/libvirt-spice/server-cert.pem /etc/pki/vdsm/libvirt-vnc/server-cert.pem; do echo -n "copying $x to ${x}.${mydate}" /bin/mv -n $x ${x}.${mydate} echo "[done]"; echo -n "[.] copying /tmp/new-cert.pem to $x" /bin/cp /tmp/new-cert.pem ${x} echo "[done]" echo -n "[.] setting permissions to $x 644 root:kvm" chmod 644 ${x} chown root:kvm ${x} echo "[done]" done for x in /etc/pki/vdsm/libvirt-migrate/ca-cert.pem /etc/pki/vdsm/certs/cacert.pem /etc/pki/vdsm/libvirt-vnc/ca-cert.pem /etc/pki/vdsm/libvirt-spice/ca-cert.pem /etc/pki/CA/cacert.pem; do echo -n "copying $x to ${x}.${mydate}" /bin/mv -n $x ${x}.${mydate} echo "[done]" echo -n "[.] copying /tmp/new-ca.pem to $x" /bin/cp /tmp/new-ca.pem ${x} echo "[done]"; echo -n "[.] setting permissions to $x 644 root:kvm" chmod 644 ${x} chown root:kvm ${x} echo "[done]" done for x in /etc/pki/vdsm/keys/vdsmkey.pem; do echo -n "copying $x to ${x}.${mydate}" /bin/mv -n $x ${x}.${mydate} echo "[done]" echo -n "[.] copying /etc/pki/libvirt/private/clientkey.pem to $x" /bin/cp /etc/pki/libvirt/private/clientkey.pem ${x} echo "[done]"; echo -n "[.] setting permissions to $x 644 root:kvm" chmod 644 ${x} chown root:kvm ${x} echo "[done]" done echo "[.] Checks " openssl x509 -in /etc/pki/libvirt/clientcert.pem -noout -dates openssl x509 -in /etc/pki/vdsm/certs/cacert.pem -noout -dates openssl x509 -in /etc/pki/vdsm/certs/vdsmcert.pem -noout -dates openssl x509 -in /etc/pki/vdsm/libvirt-migrate/ca-cert.pem -noout -dates openssl x509 -in /etc/pki/vdsm/libvirt-migrate/client-cert.pem -noout -dates openssl x509 -in /etc/pki/vdsm/libvirt-migrate/server-cert.pem -noout -dates openssl x509 -in /etc/pki/vdsm/libvirt-spice/ca-cert.pem -noout -dates openssl x509 -in /etc/pki/vdsm/libvirt-spice/server-cert.pem -noout -dates ```` Note: I whould backup the entire pki folder on both node and engine.

snapshot solution: Existing snapshots that were taken after this one will be erased.
by dhanaraj.ramesh＠yahoo.com 29 Jan '25

29 Jan '25

Hi Team, when I want to commit the older snapshots I'm getting warning stating " Existing snapshots that were taken after this one will be erased.". is there any way we can retain the latest snapshots as is in the chain? I knew cloning and template export options are there to secure that latest snapshot data but these are will consume additional space in storage and take time.

Currently linux vm which i am trying to migrate has 4 (500GB) disk. All disks on same datastore. It is iscsi datastore. Do we have any configuration where we can enabled verbose mode while migration is going on to see what is happening as currently unable to identify failure. Also is there any limitation if vms with multiple disk is not possible to migrate?

oVirt Translations & Future
by Jean-Louis Dupond 23 Jan '25

23 Jan '25

Hi, We've setup some alternative for the (dead) Zanata translation project for oVirt. You can find the Weblate setup on the following location: https://translate.ovirt.tech/projects/ovirt-engine/ So if somebody wants to add translations, feel free! :) Will try to add translations for the other projects the coming days. Next to that, we are working hard to get oVirt better! If you want to help, feel free to open PR's or send me an mail. A lot can be done, so you won't get bored. Some things that we are looking into: - Java updates - Wildfly update - AlmaLinux 10 / CentOS Stream 10 support Feel free to contact me if you have further questions. Jean-Louis

Hi Guys, Can someone please confirm if 5th Gen Intel Gold (Emerald Rapids) CPUs are compatible with OLVM/ovirt 4.5.5.x? We have a OLVM/ovirt 4.5.5.x test lab setup cluster running on older hardware (Intel(R) Xeon(R) CPU E5-2660 v3 @ 2.60GHz - Haswell Family) with compatibility version 4.7. While going through the engine db backup we observed that there are no entries in the vdc_options table for Emerald Rapids family of Intel CPUs.

Re: [External] : The KVM Host Status Stucking in Connecting
by natchawi28＠gmail.com 23 Jan '25

Hi, What about the version differences between the Engine and the KVM host? Does it matter? Engine: Oracle Linux 8.10 Kernel 5.15.0-302.167.6.el8uek.x86_64 KVM Host: Oracle Linux 8.6 Kernel 5.4.17-2136.311.6.1.el8uek.x86_64 I checked the Cluster Compatibility Version, and it appears to be compatible. Thank you,
