To follow up on my issues, I can boot if I choose just one cpu, so it's probably not an issue with this plugin specifically. It is more likely to be UnRAID itself.   If I set one cpu and also hypervisor.cpuid.v0 = FALSE in the vmx file I can get it to boot and the plugin appears to be working as expected. @ich777- if you can think of any logs etc. to get this resolved let me know
