Vm can't migrate

[genialweb]

Good morning, why does this VM not want to migrate to another node?

kvm: cannot set up guest memory ‘pc.ram’: Cannot allocate memory

This is the key!

From my point of view it would be better the machine rest in the PENDING state. By the way, try increase the reserver memory in the HOST configuration

Another work around is to temporary “disable” the node and re instantiate the VM so can be placed on another node and then re-enable the original node.

Be aware of manual placing the VM on a node as the information you have on real memory available are not always true so you can get problems.

Hope this help you.

Best Regards

Thank you Luigi,
I had to restart the node… there is something that did not go …
