Someone mentioned turning off exclusive use of hardware virtualization in a
freebsd-hackers discussion about running VirtualBox and bhyve side by side
(https://lists.freebsd.org/archives/freebsd-hackers/2022-June/001299.html). I
had a hunch that this setting might also affect this issue, turned it off
(vboxmanage setproperty hwvirtexclusive off), and now I can suspend/resume the
host with running VMs. So this seems to be a good workaround, and also might
narrow down the issue.
