a5de49558e vmm: Only allow removal of specific types of virtio device
Now that all virtio devices are assigned with identifiers, they could
all be removed from the VM. This is not something that we want to allow
because it does not make sense for some devices. That's why based on the
device type, we remove the device or we return an error to the user.

e1a07ce3c4 vmm: vm: Unpark the threads before shutdown when the current state is paused
If the current state is paused that means most of the handles got killed by pthread_kill
We need to unpark those threads to make the shutdown worked. Otherwise
The shutdown API hangs and the API is not responding afterwards. So
before the shutdown call we need to resume the VM make it succeed.
