alpine linux under vm? freezes

Hello,

I tried to run alpine linux (alpine-virt-3.8.0-x86_64.iso)
under the OpenBSD (latest snapshot) virtual machine.

I was able to boot it, even to install it to an image.

I connect to the console with the 'vmctl console' command.
At various moments I am no longer able to write anything,
the alpine system as if freezes.

Has anybody encountered something similar?

Thanks for any comments.

Thanks
Ruda



PS.: I like OpenBSD but I seem to need some linux, too,
for various programs (Julia, J, Texmacs, reduce,
pressure sensitivity for a Wacom Intuos 3 tablet, ...)
