Bcp vm
by Ali Gusainov 27 Jun '23

27 Jun '23

Hello experts. Environment: 2 identical servers running CentOS Linux release 7.7.1908 oVirt Version:4.3.7.2-1.el7 No clusters configured. NFS share for backups on third server. Have some questions. 1. Need to create backups of virtual machines to NFS without downtime. Can an 'OVA export' be a complete policy for backups? 2. Is there a way to export vm to OVA via command line?

How to add alternate fqdn
by BJ一哥 27 Jun '23

27 Jun '23

Version 4.5.1 I try to modify the parameter of SSO_ALTERNATE_ENGINE_FQDNS in /etc/ovirt-engine/engine.conf.d/11-setup-sso.conf to a new domain name The web interface opens normally, but the management portal cannot be accessed. Entering the management portal prompts 500 internal Server error

HostEngine added alternate fqdn cannot be accessed
by ziyi Liu 26 Jun '23

26 Jun '23

I modified the parameter of SSO_ALTERNATE_ENGINE_FQDNS to the new fqdn in /etc/ovirt-engine/engine.conf.d/11-setup-sso.conf. After modifying the hosts, I can use the new fqdn to open the web but cannot enter the portal management, prompting 500 Internal Server Error

lacks the ovirt-engine CA in it's trust store. You should try importing the CA first before opening the console.vv file. It's not possible* to use a third party CA to secure the VNC connections. As the VNC connections originate on the virtualization hosts themselves, the CA that they use is the internal ovirt-engine CA that was automatically generated by engine-setup. If you don't want to import the ovirt-engine CA on the end-user machines, your best option is to force end users through the end-user portal. Alternatively, you could disable VNC encryption entirely and secure the link via other means. *: Technically it is possible to use a third party CA cert on the VNC connections, but it will only work until VDSM reboots the host or performs a host upgrade. As there is no way to force VDSM to ignore the "invalid" custom cert. -Patrick Hibbs > The solutions provided here was not successfull > https://access.redhat.com/solutions/6217601 > > BR > > R A > > > _______________________________________________ > Users mailing list --users(a)ovirt.org > To unsubscribe send an email tousers-leave(a)ovirt.org > Privacy Statement:https://www.ovirt.org/privacy-policy.html > oVirt Code of Conduct:https://www.ovirt.org/community/about/community-guidelines/ > List Archives:https://lists.ovirt.org/archives/list/users@ovirt.org/message/XG7T…

Hello, i am using ovirt 4.5.4-1.el9 standalone on Rocky Linux and have some struggle with vnc connection. I ve engine.mydomain.de which contains the ovirt-engine. I installed third party certificate successfully. So when i call engine.mydomain.de/ovirt-engine or node1.mydomain.de:9090 the browser tell me that connection is secured. My first host is node1.mydomain.de, which has currently one VM up. On Linux Client (Rocky Linux 9.2) 1. When i run "remote-viewer --debug /home/user1/Downloads/console.vv --gtk-vnc-debug" everything works fine. RemoteViewer opens and i can see the console of my vm 2. When i try to open the console.vv directly via remoteViewer from enngine-portal i get feedback from remoteViewer: "The certificate is not trusted" 3. When i try to open via novnc a new tab opens and i get "Something went wrong, connection is closed" On Windows 11 1. When i generate the console.vv and copy the password and hostadress + port to TigerVNC client everything work fine. TigerVNC tells me that connection is secured 2. When opening console.vv directly via RemoteViewer i get "Filed to complete handshake Error in the pull function 3. When i try to open via novnc a new tab opens and i get "Something went wrong, connection is closed" 4. When i run "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\VirtViewer\Remote viewer.lnk" --debug C:\Users\rezaa\Downloads\console.vv --gtk-vnc-debug I get : C:\Users\rezaa>"C:\ProgramData\Microsoft\Windows\Start Menu\Programs\VirtViewer\Remote viewer.lnk" --debug C:\Users\rezaa\Downloads\console.vv --gtk-vnc-debug C:\Users\rezaa>(remote-viewer.exe:9460): virt-viewer-DEBUG: 19:16:33.218: keymap string is empty - nothing to do (remote-viewer.exe:9460): virt-viewer-DEBUG: 19:16:33.264: Opening display to C:\Users\rezaa\Downloads\console.vv (remote-viewer.exe:9460): virt-viewer-DEBUG: 19:16:33.265: Guest (NULL) has a vnc display (remote-viewer.exe:9460): gtk-vnc-DEBUG: 19:16:33.271: ../src/vncconnection.c Init VncConnection=00000000070f1c90 (remote-viewer.exe:9460): gtk-vnc-DEBUG: 19:16:33.271: ../src/vncdisplaykeymap.c Using Win32 virtual keycode mapping (remote-viewer.exe:9460): gtk-vnc-DEBUG: 19:16:33.272: ../src/vncdisplay.c Grab sequence is now Control_L+Alt_L (remote-viewer.exe:9460): libsoup-WARNING **: 19:16:33.277: Could not set SSL credentials from '/etc/pki/tls/certs/ca-bundle.crt': Vertrauenswürdigkeitsliste konnte nicht aus /etc/pki/tls/certs/ca-bundle.crt befüllt werden: Error while reading file.

Hi. I have a (mostly) working Ovirt setup - i.e everything is working as far as I can tell. I have a 'standalone Manager with local databases' setup and several nodes. On all nodes I see this error constantly produced ----- Jun 23 15:50:26 ovirt-node2 vdsm[10344]: ERROR ssl handshake: socket error, address: ::ffff:127.0.0.1 Jun 23 15:50:26 ovirt-node2 vdsm[10344]: WARN unhandled write event ----- As mentioned everything seems to be working, all nodes are up, I can update them , etc. Is the error perhaps related to no ipv6 access and I can safely ignore ? I have an installed cert (not self signed) which i have added to the web ui - could this be connected ? If so can someone confirm which certs and ca should be the same/match (engine and nodes)? One issue I am having is that live migration seems to randomly fail (i.e message is migration was cancelled) could see anything obvious looking at the logs
