First of all attach serial console to VM and see if there is any kernel messages printed upon crash.

Perhaps you are right, furthermore I can not see FreeBSD version of that function, so currently we have at least two different approaches: - Rollback to an old version of system memory calculation method (which was a dirty hack,according to code comments) - Or just implement such function and send it upstream. The second way seems to me more preferable. It takes me a few days, until that you have to use cli tools or previous VirtualBox port revision from svn. > > Oli > ___ > freebsd-virtualization@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization > To unsubscribe, send any mail to > "freebsd-virtualization-unsubscr...@freebsd.org" -- Михаил ___ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"

I confirm the problem. Apparently this is a regression in the latest version.
