The guest vm is non-hvm and the host is non-hvm, so viridian=true should be OK? Also, other guest vms are running fine with viridian=true.

Ok, so from my understanding, you can't run a HVM guest with VIRIDIAN set to true.

Can you use the xe vm-param-set functionality to switch Viridian to false and try again.
