I also get crashes when running OpenBSD on MP kernel in XEN, however, SP kernels work fine. On the boot> prompt, try boot /bsd.sp. Don't know, if just reconfiguring the VM, and booting a MP kernel with a single CPU helps/works too. I haven't had time or necessity yet, to look into it a bit closer, maybe playing with XEN config option i.e. noapic, or noacpi etc. in the xen config file might or might not help. I currently only need "small" machines, where one CPU core is enough. cheers, Sebastian > Following is the dmesg output : > > OpenBSD 5.6 (GENERIC.MP) #333: Fri Aug 8 00:20:21 MDT 2014 > [email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP > real mem = 109047808 (103MB) > avail mem = 97517568 (93 MB) > mpath0 at root > scsibus0 at mpath0: 256 targets > mainbus0 at root > bios0 at mainbus0: SMBIOS rev. 2.4 @ 0xfc001000 (12 entries) > bios0: vendor Xen version "4.4.1" date 12/11/2014 > bios0: Xen HVM domU > acpi at bios0 not configured > mpbios0 at bios0: Intel MP Specification 1.4 > cpu0 at mainbus0: apid 0 (boot processor) > cpu0: Intel(R) Celeron(R) CPU G1610 @ 2.60GHz, 2594.52 MHz > cpu0: > FPU,VMC,DE,PSE,TSC,MSR,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,CFLUSH,MMX, > FXSR,SSE,SSE2,HTT,SSE3,PCLMUL,SSSE3,CX16,PCID,SSE4.1,SSE3.2,x2APIC,POPCNT,DEADL > INE,XSAVE,FSGSBASE,SMEP,ERMS > cpu0: 256KB 64b/line 8-way L2 cache > cpu0: smt 0, core 0, package 0 > mtrr: Pentium Pro MTRR support, 8 var ranges, 88 fixed ranges > cpu0: apic clock running at 100MHz > cpu1 at mainbus0: apid 2 (application processor) > cpu1: Intel(R) Celeron(R) CPU G1610 @ 2.60GHz, 2594.36 MHz > cpu1: > FPU,VMC,DE,PSE,TSC,MSR,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,CFLUSH,MMX, > FXSR,SSE,SSE2,HTT,SSE3,PCLMUL,SSSE3,CX16,PCID,SSE4.1,SSE3.2,x2APIC,POPCNT,DEADL > INE,XSAVE,FSGSBASE,SMEP,ERMS > cpu1: 256KB 64b/line 8-way L2 cache > cpu1: smt 0, core 1, package 0 > mpbios0: bus 0 is type ISA > ioapic0 at mainbus0: apid 1 pa 0xfec00000, version 11, 48 pins > ioapic0: misconfigured as apic0, remapped to apid 1 > pci0 at mainbus bus 0 > pchb0 at pci0 dev 0 function 0 "Intel 82441FX" rev 0x02 > pcib0 at pci0 dev 1 function 0 "Intel 82371SB ISA" rev 0x00 > pciide0 at pci0 dev 1 function 1 "Intel 82371SB IDE" rev 0x00: DMA, channel 0 > w > ired to compatibility, channel 1 wired to compatibility > wd0 at pciide0 channel 0 drive 0: <QEMU HARDDISK> > wd0: 16-sector PIO, LBA48, 51200MB, 104857600 sectors > wdi1 at pciide0 channel 0 drive 1: <QEMU HARDDISK> > wd1: 16-sector PIO, LBA48, 128MB, 262144 sectors > wd0(pciide0:0:0): using PIO mode 4, DMA mode 2 > wd1(pciide0:0:1): using PIO mode 4, DMA mode 2 > atapiscsi0 at pciide0 channel 1 drive 0 > scsibus1 at atapiscsi0: 2 targets > cd0 at scsibus1 targ 0 lun 0: <QEMU, QEMU DVD-ROM, 2.1.> ATAPI 5/cdrom > removabl > e > cd0(pciide0:1:0): using PIO mode 4, DMA mode 2 > "XenSource Platform Device" rev 0x01 at pci0 dev 2 function 0 not configured > vga1 at pci0 dev 3 function 0 "Cirrus Logic CL-GD5446" rev 0x00 > wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) > wsdisplay0: screen 1-5 added (80x25, vt100 emulation) > re0 at pci0 dev 4 function 0 "Realtek 8139" rev 0x20: RTL8139C+ (0x7480), > apic 1 > int 5, address 00:16:3e:b4:5a:29 > rlphy0 at re0 phy 0: RTL internal PHY > isa0 at pcib0 > isadma0 at isa0 > com0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo > com0: probed fifo depth: 0 bytes > pckbc0 at isa0 port 0x60/5 > pckbd0 at pckbc0 (kbd slot) > pckbc0: using irq 1 for kbd slot > wskbd0 at pckbd0: console keyboard, using wsdisplay0 > pms0 at pckbc0 (aux slot) > pckbc0: using irq 12 for aux slot > wsmouse0 at pms0 mux 0 > pcppi0 at isa0 port 0x61 > spkr0 at pcppi0 > fdc0 at isa0 port 0x3f0/6 irq 6 drq 2 > fd0 at fdc0 drive 1: density unknown > nvram: invalid checksum > vscsi0 at root > scsibus2 at vscsi0: 256 targets > softraid0 at root > scsibus3 at softraid0: 256 targets > root on wd0a (dbd5aff2bf9a7bb0.a), swap on wd0b dump on wd0b > clock: unknown CMOS layout > kernel: double fault trap, code=0 > Stopped at 0: kernel: page fault trap, code=0 > Stopped at db_read_bytes+0x22: movzbl 0(%rdi,%rcx,1),%eax > > Following is the trace: > > ddb{1}> trace > db_read_bytes() at db_read_bytes+0x22 > db_get_value() at db_get_value+0x34 > db_disasm() at db_disasm+0x42 > db_trap() at db_trap+0x90 > kdb_trap() at kdb_trap+0xf0 > trap() at trap+0x15d > --- trap (number 13) --- > mpidle() at 0 > cpu_spinup_trampoline_end() at cpu_spinup_trampoline_end+0x67 > end trace frame: 0x0, count = -8 > > I don't know if I should provide anything else, if you need something please > tell me. > > Thank you for any help
