Hello,
The official FreeBSD snapshot FreeBSD-13.0-CURRENT-362037-amd64-vm.raw
appears to panic as a guest under 12.1p5 and 12.1p1.
Boot syntax:
sh /usr/share/examples/bhyve/vmrun.sh -c 1 -t tap0 -d <img> vm
I have tried it with one and two vCPUs, and the -a and -A flags to vmrun.sh.
Most boots panic at:
btext() at btext+0x2c
KDB: enter: panic
Some get to this until destroyed externally:
Trying to mount root from ufs:/dev/gpt/rootfs [rw]...
Assertion failed: (error == 0), function emulate_inout, file
/usr/src/usr.sbin/bhyve/inout.c, line 232.
Abort trap
I have tried both the unmodified image and it truncated to 10G.
Full output below.
Any suggestions?
Thank you!
Michael Dexter
