Hi, I looked at the failing migrations in OST on el8, when running basic-suite-master with https://gerrit.ovirt.org/#/c/103888/31. The migration fails even before started, when Vdsm tries to talk to the remote Vdsm and can't reach it. Indeed, there seems to be a networking problem between the hosts: [root@lago-basic-suite-master-host-1 ~]# ping -c 1 lago-basic-suite-master-host-0 PING lago-basic-suite-master-host-0(lago-basic-suite-master-host-0.lago.local (fd8f:1391:3a82:201::c0a8:c902)) 56 data bytes From lago-basic-suite-master-host-1 (fd8f:1391:3a82:200::c0a8:c899): icmp_seq=1 Destination unreachable: Address unreachable
