Problem with FreeBSD as a XenServer Guest - how to debug?

[Rainer Duffner]

Hi,

I’ve opened a PR on this:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=212681

and asked on freebsd-virtualization. But nothing came out of it.

Basically, I/O is very slow inside the FreeBSD guest. Linux guests are OK.
FreeBSD 10 or 11 doesn’t make a difference.
Haven’t been able to try 12.


How can one debug this?
