#8582 fixed multiple headless VMs: VBox daemons stop without waiting for the last VM to shut down Régis Desgroppes
Description

Hi,
For continuous integration purposes, I'm running multiple concurrent headless VMs thanks to the vboxapi python bindings. This is done on demand to release resources as soon as possible.
What I observe:

  • everything goes fine when the first started VM is also the last to shut down.
  • but, if the first started VM shuts down while other VMs are still running, all remaining sessions abort (vboxapi raises a xpcom.Exception: 0x80004004, Operation aborted, NS_ERROR_ABORT) without any sort of notification to running VMs. There's even nothing in any of the VBox.logs (see attached one).


What I guess is that the first started VM "owns" the daemons so, as a workaround, I currently launch one of VBox daemons manually (/usr/lib/virtualbox/VBoxSVC --daemonize) in the hope the daemons are then owned by no peculiar VM. It still works fine after a few days.
Is there a better/recommended way to handle this?
Did I guess well and -if yes- would it be possible to replace the ownership by a reference counting?
Many thanks,
Régis

#4035 duplicate multiple descendants of a snapshot hadmut
Description

Hi,

I'd like to suggest a simple but powerful improvement: Would be really great if it was possible if a snapshot could have multiple descendants and not just a single one. E.g. one snapshot of the installed operating system and have multiple descendants to test and compare different software.

regards Hadmut
