Hi, Anyone have compiled these deb packages for Debian 11 Bullseye? oVirt guest agent + spice-vdagent Packages from Buster can’t be installed on Bullseye because of broken libnl dependencies. Thanks in advance. Andrei

GPG key <infra@ovirt.org> expired since April ?
by Fredrik Arneving 20 Oct '21

20 Oct '21

Hi, According to output pasted below it seems that the GPG key used to sign installation media has expired 2021-04-03. Why is new installation ISO signed 7 days ago with a key that has been expired for almost 6 months? Is this correct? My main question though is if this iso is authentic? $ ll -h ovirt-node-ng-installer-4.4.8-2021090310.el8.iso* -rw-r--r--. 1 fredde fredde 1.9G Oct 1 14:48 ovirt-node-ng-installer-4.4.8-2021090310.el8.iso -rw-r--r--. 1 fredde fredde 32 Oct 1 14:48 ovirt-node-ng-installer-4.4.8-2021090310.el8.iso.md5sum -rw-r--r--. 1 fredde fredde 490 Oct 1 14:48 ovirt-node-ng-installer-4.4.8-2021090310.el8.iso.md5sum.sig $ gpg --list-keys oVirt pub rsa2048 2014-03-30 [SC] [expired: 2021-04-03] 31A5D7837FAD7CB286CD3469AB8C4F9DFE590CB7 uid [ expired] oVirt <infra(a)ovirt.org> $ gpg --verify-files *.sig gpg: assuming signed data in 'ovirt-node-ng-installer-4.4.8-2021090310.el8.iso.md5sum' gpg: Signature made Thu 23 Sep 2021 02:41:24 PM CEST gpg: using RSA key AB8C4F9DFE590CB7 gpg: Good signature from "oVirt <infra(a)ovirt.org>" [expired] gpg: Note: This key has expired!

UEFI Guest can only be started on UEFI host (4.4)
by nroach44＠nroach44.id.au 20 Oct '21

20 Oct '21

Hi All, A problem I've just "dealt with" over the past months is that the two UEFI VMs I have installed (One Windows 10, one RHEL8) will only start on the oVirt Node (4.4.x, still an issue on 4.4.8) hosts that have been installed using UEFI. In the case of both guests, they will "start" but get stuck on a small 640x480-ish black screen, with no CPU or disk activity. It looks as if the VM has been started with "Start paused" enabled, but the VM is not paused. I've noticed that this matches the normal startup of the guest, although it only spends a second or two like that before TianoCore takes over. Occasionally, I'm able to migrate the VM to a BIOS host. When it fails, the following is seen on the /sending/ host: 2021-09-21 20:09:42,915+0800 ERROR (migsrc/86df93bc) [virt.vm] (vmId='86df93bc-3304-4002-8939-cbefdea4cc60') internal error: qemu unexpectedly closed the monitor: 2021-09-21T12:08:57.355188Z qemu-kvm: warning: Spice: reds.c:2305:reds_handle_read_link_done: spice channels 1 should be encrypted 2021-09-21T12:08:57.393585Z qemu-kvm: warning: Spice: reds.c:2305:reds_handle_read_link_done: spice channels 3 should be encrypted 2021-09-21T12:08:57.393805Z qemu-kvm: warning: Spice: reds.c:2305:reds_handle_read_link_done: spice channels 4 should be encrypted 2021-09-21T12:08:57.393960Z qemu-kvm: warning: Spice: reds.c:2305:reds_handle_read_link_done: spice channels 2 should be encrypted 2021-09-21T12:09:40.799119Z qemu-kvm: warning: TSC frequency mismatch between VM (3099980 kHz) and host (3392282 kHz), and TSC scaling unavailable 2021-09-21T12:09:40.799228Z qemu-kvm: error: failed to set MSR 0x204 to 0x1000000000 qemu-kvm: ../target/i386/kvm/kvm.c:2778: kvm_buf_set_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.

Power Saving schedule, hosts not shutting down
by Maton, Brett 20 Oct '21

20 Oct '21

Hi, I'm having trouble with the power_saving Scheduling Policy not shutting down idle hosts Policy is more or less default, I added 'HostsInReserve 0' too see if that would help, and then 24hrs later I bumped CpuOverCommitDurationMinutes to 15 that didn't make a difference either. (not unexpected as the CPU is only being tickled by two small VMs at the moment). 3x Dell Hosts with iDRAC 8 management cards, power management configured and functional. oVrit 4.4.8.6-1.el8 Thanks in advance for any help Brett

Assigning public IPs to a VM
by admin＠foundryserver.com 19 Oct '21

19 Oct '21

My provider will give me 20 public IP's, and attach them to each of my hosts. So a total of 60. The question I have, is I have two nics on the host, public and private. Is assigning the public IP as simple as selecting the public network and typing in one of the public IP's? I am still trying to get my hosted engine running, so at this point can't try this. Just thought I would ask in advance. Again Thank you for any help. Brad

Understanding Cluster Networking between Hosts
by admin＠foundryserver.com 18 Oct '21

18 Oct '21

Hello everyone. I am looking to setup a ovrit cluster. I am struggling with the network side of things. I have watched some videos about Ovirt and kvm/libvirt. I understand the bridge and NAT networks. The part I am struggling with is the host network. Here is my setup. I have two bare metal servers, that have one physical nic with a public IP. There is no private physical network on these boxes virtual or physical. I want to host an application on a single vm for each customer. the customer access the application via username.domain.com. So the question is. I have to have a layer 7 load balancer to route the url to an IP. This load balancer is haproxy on a separate bare metal box. (it could be in a vm on one of the hosts) So the load balancer has to be on the same network as all the vms. I just don't know to setup the networking between the LB on one box and the vm's on potentially may bare metal hosts. It really feels like I am missing something really obvious. All the videos I have watched all assume the host networking is already in place. Any help or resources I can read/watch would really be helpful. Brad

Ovirt VM started with old snapshots but with current disk missing
by samuel.xhu＠horebdata.cn 17 Oct '21

17 Oct '21

Hi, all: I have an ovirt 4.3 environment of 3 nodes. While i am using the following command (qemuCmd = 'qemu-img convert -p -c -O qcow2 '+backy2Source+' '+RESTOREPATH+disk.id) to merge qemu diks to do backup using backy2, unfortnately a power cut happened. After the power is back, the current disk disappeared in web UI and the recent data is lost when i restarted the virtual machine. But I could see the disk (44dd7a6f...) still exist, but Ovirt can not recognize it. How could i restore the disk identified by 44dd7a6f... so that ovirt can recognize it again? Anyone can help? Thanks!

HA VM and vm leases usage with site failure
by Gianluca Cecchi 17 Oct '21

17 Oct '21

Hello, supposing latest 4.4.7 environment installed with an external engine and two hosts, one in one site and one in another site. For storage I have one FC storage domain. I try to simulate a sort of "site failure scenario" to see what kind of HA I should expect. The 2 hosts have power mgmt configured through fence_ipmilan. I have 2 VMs, one configured as HA with lease on storage (Resume Behavior: kill) and one not marked as HA. Initially host1 is SPM and it is the host that runs the two VMs. Fencing of host1 from host2 initially works ok. I can test also from command line: # fence_ipmilan -a 10.10.193.152 -P -l my_fence_user -A password -L operator -S /usr/local/bin/pwd.sh -o status Status: ON On host2 I then prevent reaching host1 iDRAC: firewall-cmd --direct --add-rule ipv4 filter OUTPUT 0 -d 10.10.193.152 -p udp --dport 623 -j DROP firewall-cmd --direct --add-rule ipv4 filter OUTPUT 1 -j ACCEPT so that: # fence_ipmilan -a 10.10.193.152 -P -l my_fence_user -A password -L operator -S /usr/local/bin/pwd.sh -o status 2021-08-05 15:06:07,254 ERROR: Failed: Unable to obtain correct plug status or plug is not available On host1 I generate panic: # date ; echo 1 > /proc/sys/kernel/sysrq ; echo c > /proc/sysrq-trigger Thu Aug 5 15:06:24 CEST 2021 host1 correctly completes its crash dump (kdump integration is enabled) and reboots, but I stop it at grub prompt so that host1 is unreachable from host2 point of view and also power fencing not determined At this point I thought that VM lease functionality would have come in place and host2 would be able to re-start the HA VM, as it is able to see that the lease is not taken from the other host and so it can acquire the lock itself.... Instead it goes through the attempt to power fence loop I wait about 25 minutes without any effect but continuous attempts. After 2 minutes host2 correctly becomes SPM and VMs are marked as unknown At a certain point after the failures in power fencing host1, I see the event: Failed to power fence host host1. Please check the host status and it's power management settings, and then manually reboot it and click "Confirm Host Has Been Rebooted" If I select host and choose "Confirm Host Has Been Rebooted", then the two VMs are marked as down and the HA one is correctly booted by host2. But this requires my manual intervention. Is the behavior above the expected one or the use of VM leases should have allowed host2 to bypass fencing inability and start the HA VM with lease? Otherwise I don't understand the reason to have the lease itself at all.... Thanks, Gianluca
