Hannes Mehnert d83986cab4 vmmd: initialise nocrypto 2018-04-05 02:14:49 +02:00
Hannes Mehnert 9696953cd7 revise force-restart: now with wait for kill and resource cleanup before start 
allows to cleanup various hacks, such as checking for pid in vmm_resources
or removing temporarily the allocated resources from the resource map in vmm_engine

semantics is now slightly different, but for sure enhanced.
- each VM has a Lwt.wait () task attached in Vmm_engine.t (tasks : 'c String.Map.t)
- normal create shouldn't be much different, apart from memoizing the sleeper
- after waitpid is done in vmmd, and vmm_engine.shutdown succeeded, Lwt.wakeup is called for the sleeper
- force create now:
 - checks static policies
 - looks for existing VM (and task), if present: kill and wait for task in vmmd
 - continue with presence checking of vm name, dynamic policies, allocate resources (tap, img, fifo)

this means the whole randomness in filenames can be removed, and the
communication between vmm_console and vmm_client is working again (attach/detach
could not work since vmm_console knew only about "albatross.AAA.BBB.RANDOM",
whereas vmm_client insisted on "AAA.BBB"

resource overcommitment (and races in e.g. block device closing + opening) are
gone now, only if the old vm is cleanup up, resources for the new one are
allocated and it is executed
