Excellent, thanks very much. I'll bk pull and try asap. -Andrew Bin Ren wrote: I've fixed this bug in the unstable repository. It's caused by two improperly set memory-related parameters and an lack of initialization of machine-to-phys mapping for newly allocated pages for the created domains. - Bin On 4/25/05, Andrew Theurer <habanero@xxxxxxxxxx> wrote:On Monday 25 April 2005 16:54, Keir Fraser wrote:On 25 Apr 2005, at 21:03, Jacob Gorm Hansen wrote:Do you know how the interface has changed, i.e. what I need to modify in vmtools (xend is not an option since I am running with my own userspace relinked above 0xf0000000 in dom0) to get this working again?I don't think this was the problem actually, but anyway: createdomain no longer takes memsize nor initial mem size. To pin to a cpu you now use DOM0_PINCPU. To set max mem reservation you use DOM0_SETMAXMEM. To actually reserve memory you use do_dom_mem_op(MEMOP_increase_reservation).FWIW, I think I am hitting an BUG on that very changeset (1.1367) by trying to start a smp domU. I have narrowed it down the 1.1367, and I am going to remove that diff from very latest bk pull an see what happens. -Andrew BUG output: Starting domain dom1 ------------[ cut here ]------------ kernel BUG at <bad filename>:46733! invalid operand: 0000 [#1] PREEMPT Modules linked in: ipt_MASQUERADE iptable_nat ip_conntrack ip_tables qla2300 qla2xxx scsi_transport_fc mptscsih mptbase CPU: 0 EIP: 0061:[<c014c6e8>] Not tainted VLI EFLAGS: 00010286 (2.6.11-xen0-up) EIP is at page_remove_rmap+0x3d/0x47 eax: ffffffff ebx: 00000000 ecx: c04f771c edx: c16fdfe0 esi: f48d5494 edi: 0feff067 ebp: 00001000 esp: f459de48 ds: 007b es: 007b ss: 0069 Process python (pid: 4300, threadinfo=f459c000 task=f76c3a80) Stack: c1641640 f459c000 c0145244 c16fdfe0 0a3d5067 c01471fe 00000010 c16fdfe0 00000000 b7525000 c04f771c b7925000 f455fb78 b7526000 00000000 c0145408 c04f771c f455fb74 b7525000 00001000 00000000 b7525000 f455fb78 b7526000 Call Trace: [<c0145244>] zap_pte_range+0x186/0x2f3 [<c01471fe>] do_anonymous_page+0x169/0x210 [<c0145408>] zap_pmd_range+0x57/0x75 [<c0145460>] zap_pud_range+0x3a/0x5e [<c01454f8>] unmap_page_range+0x74/0x8b [<c014560c>] unmap_vmas+0xfd/0x223 [<c0149ff4>] unmap_region+0x7b/0xe9 [<c014a2c8>] do_munmap+0x122/0x191 [<c014a37e>] sys_munmap+0x47/0x62 [<c010965c>] syscall_call+0x7/0xb Code: 0f 98 c0 84 c0 74 1c 8b 42 08 83 c0 01 78 1c c7 44 24 04 ff ff ff ff c7 04 24 10 00 00 00 e8 a3 ef fe ff 83 c4 08 c3 0f 0b eb d1 <0f> 0b 8d b6 00 00 00 00 eb da 55 57 56 53 83 ec 1c 8b 4c 24 34 <6>note: python[4300] exited with preempt_count 1 scheduling while atomic: python/0x00000001/4300 [<c03ae564>] schedule+0x534/0x5d8 [<c010980b>] hypervisor_callback+0x37/0x40 [<c03af64d>] rwsem_down_read_failed+0x8d/0x18b [<c011da4b>] .text.lock.exit+0x27/0x8c [<c010a33f>] do_invalid_op+0x0/0xab [<c011c212>] do_exit+0x9d/0x36b [<c010a33f>] do_invalid_op+0x0/0xab [<c010a02d>] do_trap+0x0/0xd5 [<c010a3e1>] do_invalid_op+0xa2/0xab [<c014c6e8>] page_remove_rmap+0x3d/0x47 [<c013aa7e>] rmqueue_bulk+0x4a/0xd5 [<c013a94a>] prep_new_page+0x72/0x77 [<c013adfe>] buffered_rmqueue+0x153/0x2ba [<c01097cc>] error_code+0x38/0x40 [<c014c6e8>] page_remove_rmap+0x3d/0x47 [<c0145244>] zap_pte_range+0x186/0x2f3 [<c01471fe>] do_anonymous_page+0x169/0x210 [<c0145408>] zap_pmd_range+0x57/0x75 [<c0145460>] zap_pud_range+0x3a/0x5e [<c01454f8>] unmap_page_range+0x74/0x8b [<c014560c>] unmap_vmas+0xfd/0x223 [<c0149ff4>] unmap_region+0x7b/0xe9 [<c014a2c8>] do_munmap+0x122/0x191 [<c014a37e>] sys_munmap+0x47/0x62 [<c010965c>] syscall_call+0x7/0xb _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
