Hello all.

We are having a problem with some VM's Ubuntu 22.04, that oVirt engine loses contact with the VM and rebooting it. What is strange is that it happens just to a group of machines.

We received this message when one vm is rebooted:

VM SRV-01 was configured with 102092MiB of memory while the recommended value range is 64MiB - 65536MiB

In our cluster we have enough memory per host but we already found out this other message:

failed to set up stack guard page: Cannot allocate memory

We already put the memory size and guarantee memory with the same value.

 We tried to look after any log but nothing helped give us a ideia what was going on.

The unique thing that we thought is that VM's are using UEFI but we do not know it can cause this situation.

Any of you already passed through this situation?
