@olivierlambert Thanks a lot.
The Max vCPU was larger than the Physical CPU. Now it migrates successfully.

Hi!

Take time to read the error code: HOST_NOT_ENOUGH_PCPUS

"P" is for physical. So you are trying to migrate a VM with more vCPUs than you have physical CPUs on the destination host.

Thanks for your quick response.
My host has 4 vCPU and the VM is just 1 vCPU as shown in the screenshot.

Check your VM max vCPU in the Adanvced tab.
