Hi.
I posted this a couple of days on the omnios list, but haven't gotten
much feedback. I am hoping someone here might have some clues as OI
and Omnios share the same vbox code. Posted below is some crash dump
information.
I have several machines running vbox without issue. The only thing I
can think of here is that this machine has a "newer" Intel Xeon
Silver 4110 Processor.
Any other thoughts?
That looks like the crashes we see on Solaris when SMAP is enabled on
a CPU
new enough to support it. The VirtualBox drivers try to access memory
that
SMAP blocks access to from kernel space.
https://wiki.openindiana.org/oi/7.2+VirtualBox suggests "Workaround is
to put:
set disable_smap=1 in /etc/system and reboot, before starting VirtualBox"
Hi Alan.
I tried the smap disable, doesn't seem to make a difference.
As well, I was told from the omnios list you don't need to disable smap
when using the vbox builds from omnios/OI. They now work without having
to disable it.
thanks,
Geoff
