@Dezerd To check if there is perhaps a hung process that is interfering. I assume there is sufficient memory and storage space. DO any I/O disk errors show in /var/log. SMlog ? Just to clarify. are there VMs that do not show any such error condition?

I have been in the Network Enterprise business for 28 years. I live in Virginia which is heavily populated with Data Centers and adding more all the time. However, we have quite a few customers especially municipalities which are saying NO to having anything hosted with cloud computing due to security and endless rising cost. We have been deploying xcp-ng in quite a few installations, on customer premise. I think VATES will find there is a whole other market in these areas they can reach. That being said, Thanks to VATES and all who have worked on solutions for this! It truly benefits everyone!
