Sounds like it, but VMs are running on the same network, with the same IP address. The only firewall involved are on the hosts, and they are both firewalld, and have the same ports and service permitted. -----Original Message----- From: Strahil Nikolov <hunter86_bg@yahoo.com> Sent: Sunday, January 10, 2021 10:57 PM To: users@ovirt.org; Stier, Matthew <Matthew.Stier@fujitsu.com> Subject: Re: [ovirt-users] VM console does not work with new cluster. This sounds like firewall issue.

I can access the VM console (virt-viewer) when the VM is on the 'default' cluster, but once moved to the the new cluster, virt-viewer pops up and disappears in sub-second fashion.  Moving the VM back to 'default', restores access. I'm running virt-viewer 9.0-256 on my Windows 10 Pro laptop. (for months) I'm running Oracle Linux Virtualization Manager on Oracle Linux 7u9 hosts. The new ('two') cluster hosts are connected to the same networks as the original systems ('default'). (They have the same assigned IP address.) Firewalld is reporting the same ports and services enabled on 'default' and 'two' hosts.  The VM's are not running firewalls. Apparently I'm missing something. _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@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/AAKYLXLBV2FCL5...
