I've been running a bunch of VMs on KVM/Qemu for close to 12 years now. Every year or so, I upgrade a few of them...to keep them "fresh". Now I'm trying to replace a VM having two CPUs that is has been running 6.5 since for about the last year. My general strategy is to fresh install into a second VM that becomes operational at the last minute.
I'm running into an issue that I've discovered thru testing occurs in 6.6, 6.7, and 6.8. The issue is that the reboot after install hangs on a line that says "root on wd0a (8be0ca9d19d7f68f.a) swap on wd0b dump on wd0b". If I power-off the VM, reconfigure the VM to have just one CPU, and boot it again (the same MP kernel), then OpenBSD comes up completely. So, it's not the MP kernel (bsd.mp), but the presence of the second CPU? FWIW, I'm able to install/run a VM running 6.8 no problem when NOT using the MP kernel (i.e., I provision just one CPU to the VM before installing OpenBSD). Heads up: I am running a somewhat old hypervisor: "QEMU emulator version 0.14.1 (qemu-kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard". Below is the `dmesg` output for: 1) a 6.5 MP install, running with two CPUs. 2) a 6.8 MP install, but running with just one CPU. 3) There's also a diff between the two above. Any thoughts on what may have changed, starting in 6.6 and continuing to 6.8, that would cause bsd.mp to hang when a second CPU is present? Thanks, K. ##################################################### # dmesg output for a 6.5 MP install, running with two CPUs # OpenBSD 6.5 (GENERIC.MP) #3: Sat Apr 13 14:48:43 MDT 2019 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 251645952 (239MB) avail mem = 234508288 (223MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.4 @ 0xffffec0 (11 entries) bios0: vendor Bochs version "Bochs" date 01/01/2007 bios0: Bochs Bochs acpi0 at bios0: rev 0 acpi0: sleep states S3 S4 S5 acpi0: tables DSDT FACP SSDT APIC HPET acpi0: wakeup devices acpitimer0 at acpi0: 3579545 Hz, 24 bits acpimadt0 at acpi0 addr 0xfee00000: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: QEMU Virtual CPU version 0.14.1, 7599.32 MHz, 06-02-03 cpu0: FPU,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,MMX,FXSR,SSE,SSE2,SSE3,CX16,POPCNT,HV,NXE,LONG,LAHF,ABM,SSE4A,PERF cpu0: 64KB 64b/line 2-way I-cache, 64KB 64b/line 2-way D-cache, 512KB 64b/line 16-way L2 cache cpu0: ITLB 255 4KB entries direct-mapped, 255 4MB entries direct-mapped cpu0: DTLB 255 4KB entries direct-mapped, 255 4MB entries direct-mapped mtrr: Pentium Pro MTRR support, 8 var ranges, 88 fixed ranges cpu0: apic clock running at 1390MHz cpu1 at mainbus0: apid 1 (application processor) cpu1: QEMU Virtual CPU version 0.14.1, 2515.09 MHz, 06-02-03 cpu1: FPU,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,MMX,FXSR,SSE,SSE2,SSE3,CX16,POPCNT,HV,NXE,LONG,LAHF,ABM,SSE4A,PERF cpu1: 64KB 64b/line 2-way I-cache, 64KB 64b/line 2-way D-cache, 512KB 64b/line 16-way L2 cache cpu1: ITLB 255 4KB entries direct-mapped, 255 4MB entries direct-mapped cpu1: DTLB 255 4KB entries direct-mapped, 255 4MB entries direct-mapped ioapic0 at mainbus0: apid 2 pa 0xfec00000, version 11, 24 pins, remapped acpihpet0 at acpi0: counter not incrementing acpiprt0 at acpi0: bus 0 (PCI0) acpicpu0 at acpi0: C1(@1 halt!) acpicpu1 at acpi0: C1(@1 halt!)
