http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1569 Summary: [VT-d] NIC assignment with MSI may fail to work in guest on Corei7 Platform Product: Xen Version: unstable Platform: All OS/Version: Linux Status: NEW Severity: major Priority: P1 Component: Hypervisor AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx ReportedBy: jiajun.xu@xxxxxxxxx Environment: ------------ Service Arch (ia32/ia32e/IA64): ia32e Guest Arch (ia32/ia32e/IA64): ia32e Guest OS Type (Linux/Windows): Linux Change Set: 20844 Hardware: Core i7 Other: xen-changeset: 20844:ca0759a08057 pvops git: commit 60e0545e9649b08dd8ef5f2b991930049c40537e Merge: b5624ab... 444c982... Author: Jeremy Fitzhardinge <jeremy.fitzhardinge@xxxxxxxxxx> ioemu git: commit a0066d08514ecfec34c717c7184250e95519f39c Author: Ian Jackson <ian.jackson@xxxxxxxxxxxxx> Date: Thu Jan 14 18:27:13 2010 +0000 Bug detailed description: -------------------------- NIC assignment to guest with MSI enabled may fail to work. The issue does not occur each time but reboot guest several times will reproduce it. Device assignment with pci=nomsi option has no such issue. The two NICs on Gulftown-HEDT both have the same issue. Since the bug does not occur each time, I can not make sure which old c/s is the workable one. xm dmesg log: ############ (XEN) HVM13: HVM Loader (XEN) HVM13: Detected Xen v4.0.0-rc2-pre (XEN) HVM13: CPU speed is 2400 MHz (XEN) irq.c:243: Dom13 PCI link 0 changed 0 -> 5 (XEN) HVM13: PCI-ISA link 0 routed to IRQ5 (XEN) irq.c:243: Dom13 PCI link 1 changed 0 -> 10 (XEN) HVM13: PCI-ISA link 1 routed to IRQ10 (XEN) irq.c:243: Dom13 PCI link 2 changed 0 -> 11 (XEN) HVM13: PCI-ISA link 2 routed to IRQ11 (XEN) irq.c:243: Dom13 PCI link 3 changed 0 -> 5 (XEN) HVM13: PCI-ISA link 3 routed to IRQ5 (XEN) HVM13: pci dev 01:3 INTA->IRQ10 (XEN) HVM13: pci dev 03:0 INTA->IRQ5 (XEN) HVM13: pci dev 04:0 INTA->IRQ5 (XEN) HVM13: pci dev 05:0 INTA->IRQ10 (XEN) HVM13: pci dev 02:0 bar 10 size 02000000: f0000008 (XEN) HVM13: pci dev 03:0 bar 14 size 01000000: f2000008 (XEN) HVM13: pci dev 04:0 bar 10 size 00020000: f3000000 (XEN) domctl.c:990:d0 memory_map:add: gfn=f3000 mfn=d3d00 nr_mfns=20 (XEN) HVM13: pci dev 05:0 bar 10 size 00020000: f3020000 (XEN) domctl.c:990:d0 memory_map:add: gfn=f3020 mfn=d3c20 nr_mfns=20 (XEN) domctl.c:990:d0 memory_map:add: gfn=f3040 mfn=d3c00 nr_mfns=20 (XEN) HVM13: pci dev 05:0 bar 14 size 00020000: f3040000 (XEN) HVM13: pci dev 05:0 bar 30 size 00020000: f3060000 (XEN) HVM13: pci dev 02:0 bar 14 size 00001000: f3080000 (XEN) domctl.c:990:d0 memory_map:add: gfn=f3081 mfn=d3d23 nr_mfns=1 (XEN) HVM13: pci dev 04:0 bar 14 size 00001000: f3081000 (XEN) HVM13: pci dev 03:0 bar 10 size 00000100: 0000c001 (XEN) HVM13: pci dev 04:0 bar 18 size 00000020: 0000c101 (XEN) domctl.c:1046:d0 ioport_map:add f_gport=c100 f_mport=7100 np=20 (XEN) HVM13: pci dev 05:0 bar 18 size 00000020: 0000c121 (XEN) domctl.c:1046:d0 ioport_map:add f_gport=c120 f_mport=5000 np=20 (XEN) HVM13: pci dev 01:1 bar 20 size 00000010: 0000c141 (XEN) HVM13: Multiprocessor initialisation: (XEN) HVM13: - CPU0 ... 36-bit phys ... fixed MTRRs ... var MTRRs [2/8] ... done.
