[PVE-User] OpenBSD problems (freezing console, lots of time drift) on Proxmox 5.0

[Alex Bihlmaier]

Hi - after upgrading several Proxmox setups from 
version 4.4 to 5.0 (currently 5.0-31) i have problems 
with VMs running OpenBSD (version 6.1).

phenomens i encounter are:
* reboot / shutdown on the console is not working properly.
  it results in a console freeze and 100% load on a single cpu core
* time sleep 1 should result in a total runtime of 1 second. 
  Actually on one host it gives me this:
  "sleep 1  0.00s user 0.00s system 0% cpu 17.486 total"
* ntpd is unable to keep up with a local time drift (only on one
  Intel i7 Host, another Xeon Proxmox host does not suffer from this 
  issue) and the guest clock is drifting more and more away from the
  real clock

interesting to note: after deactivating the system console on the
VGA/NoVNC and switching to a serial console the above phenomens are
fixed and the OpenBSD guest is running smoothly like with Proxmox VE
4.4.

switching from VGA system console to serial system console:

/etc/boot.conf
set tty com0


Anyone with similar issue? Maybe time for a bug submission to the
developers.


cheers
