HA VM is using a storage lease, so it cannot have a split brain. When VM is paused, it releases the lease. When VM is resumed, it tries to acquire the lease before resuming, and resume will fail if the lease is owned by another host. If you start the HA VM on another host, the other host will acquire the storage lease. Resuming the original paused VM will fail.

Hi Strahil, thank you very much for the information. Now the question is, will oVirt stay 100 % compatible to RH? As I understood it, is that oVirt will be developed for CentOS Stream and will be tested against it. RH doesn't have the same application versions than CentOS Stream, because Stream is newer and a way ahead RH, so is oVirt then. I think, we will have then the same problems with oVirt and CentOS had, where RH 8.3 was already released and CentOS 8.3 not. Now it is vice versa. Stream is first and RH later.

[ovirt-users] Re: VMware Fence Agent
I think it's easier to get the Vmware's CA certificate and import it on all hosts + engine and trust it.By default you should put it at /etc/pki/ca-trust/source/anchors/ and then use "update-ca-trust" to make all certs signed by the Vmware vCenter's CA trusted.
