Re: Panic booting snapshot image on QEMU virtual machine
Thank you so much, Stefan. I tried the fresh snapshot of Aug 14 and it works with Opteron_G2 and QEMU Virtual CPU (and probably other cpu models).

But another report said that qemu -cpu Opteron_G3 caused a panic but Opteron_G2 worked. > > cpu0: ITLB 255 4KB entries direct-mapped, 255 4MB entries direct-mapped > > cpu0: DTLB 255 4KB entries direct-mapped, 255 4MB entries direct-mapped > > uvm_fault(0x81872dd0, 0xfff78183f2b0, 0, 1) -> e > > fatal page fault in supervisor mode > > trap type 6 code 0 rip 811c17a0 cs 8 rflags 10286 cr2 > > fff78183f2b0 cpl e rsp 81a058a0 > > panic: trap type 6, code=0, pc=811c17a0 > > > > The operating system has halted. > > Please press any key to reboot. > > > > > > 6.1 release image and earlier snapshots boot fine. > > > > Could you please shed some light on this issue for I cannot find the > > reason myself. > > > > Thanks, > > Maksym > > > > > >

For this cpu type, openbsd tries to make special MSR settings to work around cpu erratas, but qemu does not emulate those MSRs. At least that was the problem with some other similar panic I got reported.

Panic booting snapshot image on QEMU virtual machine
Hello, all. I get kernel panic trying to boot snapshot image install61.iso on the amd64 QEMU virtual machine. the problem started to happen with late July snapshots. And it still happens with the latest snapshot I can obtain (Aug 11). Here is the output of the boot process: OpenBSD/amd64 CDBOOT 3.28 boot> boot /6.1/amd64/bsd.rd cannot open cd0a:/etc/random.seed: No such file or directory booting cd0a:/6.1/amd64/bsd.rd: 3361576+1459200+3877592+0+602112 [72+426552+281440]=0x98d060 entry point at 0x1000158 Copyright (c) 1982, 1986, 1989, 1991, 1993 The Regents of the University of California.
