https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219343 Bug ID: 219343 Summary: bhyve requires -w option to run FreeBSD guests on AMD A10 CPU Product: Base System Version: 11.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: misc Assignee: freebsd-bugs@FreeBSD.org Reporter: freebsd-bugs@theory14.net I must pass the "-w" option to bhyve in order for it to run FreeBSD guests = on my AMD 10-7860K CPU. Since the man page indicates this option is intended = for debugging purposes, I assume I probably shouldn't need this to run. - Without "-w", the FreeBSD install image loads the boot loader but hangs a= fter trying to boot the kernel. CPU load goes to ~ 100% - On the same machine, I've installed an OpenBSD 6.1 VM (grub2-bhyve) and d= id NOT need the "-w" option. - Kernel: FreeBSD XXXXXX 11.0-RELEASE-p9 FreeBSD 11.0-RELEASE-p9 #0: Tue A= pr 11 08:48:40 UTC 2017=20=20=20=20 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64 - This happens with both 11.0-RELEASE images and 11.0-STABLE To duplicate on a machine with an AMD A10 CPU (maybe other AMD CPU) Follow steps on https://wiki.freebsd.org/action/show/bhyve?action=3Dshow&redirect= =3DBHyVe (Q: What is the easiest way to try bhyve?): - Failure Condition -- fetch ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/VM-IMAGES/11.0-STABLE/amd64/Lat= est/FreeBSD-11.0-STABLE-amd64.raw.xz -- unxz FreeBSD-11.0-STABLE-amd64.raw.xz -- sudo sh /usr/share/examples/bhyve/vmrun.sh -d FreeBSD-11.0-STABLE-amd64.= raw vm0 -- Observe hung systems - "Fix" -- Edit vmrun.sh to add "-w" to the bhyve options -- sudo sh /usr/share/examples/bhyve/vmrun.sh -d FreeBSD-11.0-STABLE-amd64.= raw vm0 -- Observe nice and happy FreeBSD system. If you need dmesg output or anything else, I'm happy to provide. --=20 You are receiving this mail because: You are the assignee for the bug.=
