This works under FreeBSD 10.1-R and 10.2-R (with 'freebsd-update' patches) - but fails for both 10.3-R and 10-STABLE. The VM starts to migrate in XenCenter - 'lands' on the destination node (and the XenServer console tab is connected) - but the host immediately panics t= hen with the output below. I can't get a dump from this (fails, as shown below). -Karl Fatal trap 30: reserved (unknown) fault while in kernel mode cpuid =3D 0; apic id =3D 00 instruction pointer =3D 0x20:0xffffffff80e970b1 stack pointer =3D 0x28:0xfffffe002b9b0ac0 frame pointer =3D 0x28:0xfffffe002b9b0af0 code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags =3D interrupt enabled, IOPL =3D 0 current process =3D 16 (xenwatch) [ thread pid 16 tid 100033 ] stopped at lapic_ipi_vectored+0xf1: addq $0x8,%rsp db> trace Tracing pid 16 tid 100033 td 0xfffff8000242e000 lapic_ipi_vectored() at lapic_ipi_vectored+0xf1/frame 0xfffffe002b9b0af0 xctrl_suspend() at xctrl_suspend+0x317/frame 0xfffffe002b9b0b40 xctrl_on_watch_event() at xtrl_on_watch_event+0x5e/frame 0xfffffe002b9b0b70 xenwatch_thread() at xenwatch_thread+0x1cf/frame 0xfffffe002b9b0bb0 fork_exit() at fork_exit+0x9a/frame 0xfffffe002b9b0bf0 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe002b9b0bf0 --- trap 0, rip =3D 0, rsp =3D 0, rbp =3D 0 --- db> panic Uptime 2m22s Dumping 71 out of 483 MB: xbd0: dump: no more commands? ** DUMP FAILED (ERROR 16) ** Automatic reboot in 15 seconds - press a key on the console to abort --=20 You are receiving this mail because: You are the assignee for the bug.=
