[pve-devel] [PATCH qemu-server v4 4/6] re-check if VM is running and PID for KILL after timeout

[Daniel Tschlatscher <d.tschlatscher@proxmox.com>]

This avoids accidentally killing a potentially completely unrelated
process that was spawned in an edge case between the last check in the
timeout loop and the kill command.
