After the last virtualizor update I came across an error, with the information that guest-agent was not installed on the VMs, and with that and I can't see the amount of memory used in each VM. I followed the steps to install the CentOS7 guest-agent, I see the guest-agent installed inside the VM, but in the virtualizor panel everything continues as before, with the information that it is not installed: Ram : Guest agent not installed.
I have an open support ticket, but it seems that if I wait for Virtualizor support, the war in Ukraine will end and they still haven't solved my problem.
