OK,

  Need help from the smart folks. Downgrading the kernel/kernel-headers to
5.4.15 and downgrading virtualbox to the version working on 5.14 [testcase
5.2.35 (135458)] does not allow guests to start as they did before the last
update to linux 5.5. Starting the guest headless - reports it started.
However, when I open the guest via-rdesktop monitor the boot, but the boot
process would not complete and could not create the network interface enp0s3,
the udev kernel device manager will not start, the boot process cannot flush
the journal to persistent storage (??) and boot cannot create volatile files
and directories (??)

All modules build for each version of virtualbox. (5.2.35, 5.2.36 and
testcase 5.2.37 (135942)). I have tried on the downgraded 5.4.15 and LTS.
There is no combination that will start the virtualbox guests as before. There
must be another package that was updated that comes into play (python?).

Is anyone else experiencing problems with Virtualbox and has anyone else seen
similar behavior? Any workarounds. I have a number of virtualbox guests I use.
