can't use vmconsole anymore
by Nathanaël Blanchet 13 Jun '22

13 Jun '22

Hi, I was used to use the vmconsole proxy, but since a while, I'm getting this issue (currently 4.4.5): # ssh -t -p 2222 ovirt-vmconsole(a)air.v100.abes.fr connect ovirt-vmconsole(a)air.v100.abes.fr: Permission denied (publickey). I found following in the engine.log 2021-04-15 17:55:43,094+02 ERROR [org.ovirt.engine.core.services.VMConsoleProxyServlet] (default task-4) [] Error validating ticket: : sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target at java.base/sun.security.provider.certpath.SunCertPathBuilder.build(SunCertPathBuilder.java:141) at java.base/sun.security.provider.certpath.SunCertPathBuilder.engineBuild(SunCertPathBuilder.java:126) at java.base/java.security.cert.CertPathBuilder.build(CertPathBuilder.java:297) at org.ovirt.engine.core.uutils//org.ovirt.engine.core.uutils.crypto.CertificateChain.buildCertPath(CertificateChain.java:128) at org.ovirt.engine.core.uutils//org.ovirt.engine.core.uutils.crypto.ticket.TicketDecoder.decode(TicketDecoder.java:89) at deployment.engine.ear.services.war//org.ovirt.engine.core.services.VMConsoleProxyServlet.validateTicket(VMConsoleProxyServlet.java:175) at deployment.engine.ear.services.war//org.ovirt.engine.core.services.VMConsoleProxyServlet.doPost(VMConsoleProxyServlet.java:225) The user key is the good one, I use the same with my other engines and I can successfully connect to vm consoles.

looking for some ISV backup software which integrates the backup API
by Nathanaël Blanchet 08 Jun '22

08 Jun '22

Hello, We are about to change our backup provider, and I find it is a great chance to choose a full supported ovirt backup solution. I currently use this python script vm-backup-scheduler (https://github.com/wefixit-AT/oVirtBackup) but it is not the workflow officially suggested by the community (https://www.ovirt.org/develop/release-management/features/storage/backup-re…) I've been looking for a long time an ISV who supports such an API, but the only one I found is this one : Acronis Backup Advanced suggested here https://access.redhat.com/ecosystem/search/#/ecosystem/Red%20Hat%20Enterpri… I ran the trial version, but it doesn't seem to do better than the vm-backup-scheduler script, and it doesn't seem to use the backup API (attach a clone as a disk to an existing vm). Can you suggest me some other ISV solutions, if they ever exist... or share me your backup experience?

VM HostedEngine is down with error
by souvaliotimaria＠mail.com 26 May '22

26 May '22

Hello everyone, I have a replica 2 + arbiter installation and this morning the Hosted Engine gave the following error on the UI and resumed on a different node (node3) than the one it was originally running(node1). (The original node has more memory than the one it ended up, but it had a better memory usage percentage at the time). Also, the only way I discovered the migration had happened and there was an Error in Events, was because I logged in the web interface of ovirt for a routine inspection. Βesides that, everything was working properly and still is. The error that popped is the following: VM HostedEngine is down with error. Exit message: internal error: qemu unexpectedly closed the monitor: 2020-09-01T06:49:20.749126Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config, ability to start up with partial NUMA mappings is obsoleted and will be removed in future 2020-09-01T06:49:20.927274Z qemu-kvm: -device virtio-blk-pci,iothread=iothread1,scsi=off,bus=pci.0,addr=0x7,drive=drive-ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2,id=ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2,bootindex=1,write-cache=on: Failed to get "write" lock Is another process using the image?. Which from what I could gather concerns the following snippet from the HostedEngine.xml and it's the virtio disk of the Hosted Engine: <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads' iothread='1'/> <source file='/var/run/vdsm/storage/80f6e393-9718-4738-a14a-64cf43c3d8c2/d5de54b6-9f8e-4fba-819b-ebf6780757d2/a48555f4-be23-4467-8a54-400ae7baf9d7'> <seclabel model='dac' relabel='no'/> </source> <target dev='vda' bus='virtio'/> <serial>d5de54b6-9f8e-4fba-819b-ebf6780757d2</serial> <alias name='ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </disk> I've tried looking into the logs and the sar command but I couldn't find anything to relate with the above errors and determining the reason for it to happen. Is this a Gluster or a QEMU problem? The Hosted Engine was manually migrated five days before on node1. Is there a standard practice I could follow to determine what happened and secure my system? Thank you very much for your time, Maria Souvalioti

Hi all. Is it possible to configure oVirt for work with two NICs in bond/LACP across two switches, according to the image below? [image: LACP_Across_Two_Switchs.png] Thank you all. You guys do a wonderful job. -- Att, Jorge Visentini +55 55 98432-9868

OVS switch type for hosted-engine
by Devin A. Bougie 06 May '22

06 May '22

Is it possible to setup a hosted engine using the OVS switch type instead of Legacy? If it's not possible to start out as OVS, instructions for switching from Legacy to OVS after the fact would be greatly appreciated. Many thanks, Devin

USB3 redirection
by Rik Theys 19 Apr '22

19 Apr '22

Hi, I'm trying to assign a USB3 controller to a CentOS 7.4 VM in oVirt 4.1 with USB redirection enabled. I've created the following file in /etc/ovirt-engine/osinfo.conf.d: 01-usb.properties with content os.other.devices.usb.controller.value = nec-xhci and have restarted ovirt-engine. If I disable USB-support in the web interface for the VM, the xhci controller is added to the VM (I can see it in the qemu-kvm commandline), but usb redirection is not available. If I enable USB-support in the UI, no xhci controller is added (only 4 uhci controllers). Is there a way to make the controllers for usb redirection xhci controllers?

OVN routing and firewalling in oVirt
by Gianluca Cecchi 19 Apr '22

19 Apr '22

Hello, how do we manage routing between different OVN networks in oVirt? And between OVN networks and physical ones? Based on architecture read here: http://openvswitch.org/support/dist-docs/ovn-architecture.7.html I see terms for logical routers and gateway routers respectively but how to apply to oVirt configuration? Do I have to choose between setting up a specialized VM or a physical one: is it applicable/advisable to put on oVirt host itself the gateway functionality? Is there any security policy (like security groups in Openstack) to implement? Thanks, Gianluca

VM failed to start when host's network is down
by lizhijian＠fujitsu.com 08 Apr '22

08 Apr '22

Post again after subscribing the mail list. Hi guys I have an all in one ovirt environment which node installed both vdsm and ovirt-engine. I have setup the ovirt environment and it could work well. For some reasons, i have to use this ovirt with node's networking down(i unplugged the network cable) In such case, I noticed that i cannot start a VM anymore. I wonder if there is a configuration switch to enable a ovirt to work with node's networking down ? if not, may i possible to make it work by a easy way ? When i tried to start VM with ovirt API, it responses with: ```bash [root@74d2ab9cb0 ~]# sh start.sh <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <action> <async>false</async> <fault> <detail>[Cannot run VM. Unknown Data Center status.]</detail> <reason>Operation Failed</reason> </fault> <status>failed</status> </action> [root@74d2ab9cb0 ~]# sh start.sh <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <action> <async>false</async> <fault> <detail>[Cannot run VM. Unknown Data Center status.]</detail> <reason>Operation Failed</reason> </fault> <status>failed</status> </action> [root@74d2ab9cb0 ~]# ``` Attached the vdsm and ovirt-engine Thanks Zhijian

I'm trying to deploy oVirt from a self-hosted engine, but at the last step I get an engine startup error.

It seems to me that this is due to the fact that the engine receives an IP address that does not match the entry in /etc/hosts, but I do not know how to fix it. Any help is welcome, I will provide the necessary logs. Thanks
