qemu processes still running after "vagrant destroy"

[jayunit100]

I notice that after running vagrant destroy --force i still often have some QEMU processes running.

for example, running vagrant destroy --force on a 2 node cluster (1 windows, 1 linux)... i see the linux node is still running.

==> winw1: Stopping the instance...
==> winw1: Destroying the instance...
==> controlplane: Stopping the instance...
==> controlplane: Destroying the instance...

And then checking , theres still a qemu-system process...

Currently the VM is ended by sending a shutdown signal to qemu. This may have some delay or may also fail. If it still doesn't work after some time, you need to manually kill the residual processes for now.

Later I will put the 'wait-kill' logic to the plugin.
