Log message:
vmd(8): fix vm pause deadlock.
When vcpu threads pause, they are holding the run mutex lock. If
the event thread is asked to assert an
vmd has a sneaky little deadlock hidden in the pause logic related to
the use of mutexes and condition variables.
When pausing, the vcpu is holding the "run" mutex. It then sleeps
waiting for the unpause condition. If the event thread is trying to
assert an irq, it will try to lock that "run"
It annoys me how all the log messages from different vmd vm's blur
together. Here is a diff that makes them distinguishable. It also fixes
dynamic toggling of verbosity levels in virtio devices using `vmctl
log`, and now preserves the verbosity across vm reboots.
I chose the pattern "vm/ and
