When attempting to boot a Hyper-V export, the VM powers up, but shows a black screen and no CPU usage. This does not change with time.
原因
VM has a non-bootable ISO mounted.
解决办法
WORKAROUND: Check to see whether there is an ISO mounted. Possibly, an ISO called VMGuest.iso was mounted on the VM. Once this ISO is removed, the VM booted normally.
