--- Comment #12 from Marko Cupać <marko.cupac@mimar.rs> ---
Hi,

It appears that this one broke it:
https://cgit.freebsd.org/src/commit/?h=releng/15.0&id=9114e15a86949f7d168bf09dbe78a340d5444e80

The one before it works:
https://cgit.freebsd.org/src/commit/?h=releng/15.0&id=32873ecb20aebc5117a849dc9f2a11bd9b364a6b

14-STABLE works.

Setting `vm.pmap.la57=0` in /boot/loader.conf on 15.0-RELEASE-p1 host results
in bhyve VMs being able to boot.

Best regards,
