Hi Pete,
Ah I see - once I realized we had a newer kernel I didn't focus too much
on the first bug - here's the MSR's
MSR 0x480: 0x00981000 0x11e57ed0
MSR 0x482: 0xfff9fffe 0x0401e172
MSR 0x48b: 0x000003fb 0x00000000
MSR 0x48c: 0x00000f01 0x04114040
This looks very similar to comment 14 in the bug report
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203994#c14
INS/OUTS isn't marked as supported, and single-context INVEPT is
missing. As mentioned in comment 17, these are simple to work around but
other issues started to show up, indicating that other problems are at play.
Given kernel 4.15 looks like it could be from Ubuntu 16-LTS, I'd
recommend moving to 18-LTS if that is possible, since that kernel
version is known to work.
later,
Peter.
