Can I hot migrate virtual servers between Intel- and AMD-based compute resources?
There is no workaround other than cold migration. Hot migration is only supported between the following CPU architectures:
AMD to AMD
Intel to Intel
Why is my virtual server stuck in pending?
There can be a dependent task already running for your virtual server. For example, a disk resize. Check if it is the case within the Logs area. Additionally, you can check the Sysadmin Tools section and start/restart this service from there.
Where can I find the KVM live migration compatibility matrix?
