Any ideas about this issue? Thanks! > > Which version of Xen and qemu are you using? In particular, > qemu-upstream (aka qemu-xen) or qemu-traditional? And what guest are > you using? Is there anything on the xen console (either via the > serial port or 'xl dmesg')? Xen changeset is 26580, qemu commit is 656365a38e41a5b8a2c4d5ab2ada9fbf231f1ebc. BTW, it's no problem when using qemu-traditional. The guest is 64bit SLES11 SP1. The 'xl dmesg' output is as below (we did the test with 3 guests, it can be reproduced very quickly (about 20 seconds)): (XEN) HVM25: HVM Loader (XEN) HVM25: Detected Xen v4.3-unstable (XEN) HVM25: Xenbus rings @0xfeffc000, event channel 4 (XEN) HVM25: System requested SeaBIOS (XEN) HVM25: CPU speed is 2500 MHz (XEN) irq.c:270: Dom25 PCI link 0 changed 0 -> 5 (XEN) HVM25: PCI-ISA link 0 routed to IRQ5 (XEN) irq.c:270: Dom25 PCI link 1 changed 0 -> 10 (XEN) HVM25: PCI-ISA link 1 routed to IRQ10 (XEN) irq.c:270: Dom25 PCI link 2 changed 0 -> 11 (XEN) HVM25: PCI-ISA link 2 routed to IRQ11 (XEN) irq.c:270: Dom25 PCI link 3 changed 0 -> 5 (XEN) HVM25: PCI-ISA link 3 routed to IRQ5 (XEN) HVM25: pci dev 01:2 INTD->IRQ5 (XEN) HVM25: pci dev 01:3 INTA->IRQ10 (XEN) HVM25: Randy: pci_setup 0: mmio_total=0x2000000 bar_sz=0x2000000 (XEN) HVM25: Randy: pci_setup 0: mmio_total=0x2001000 bar_sz=0x1000 (XEN) HVM25: Randy: pci_setup 0: mmio_total=0x2011000 bar_sz=0x10000 (XEN) HVM25: Randy: pci_setup 0: mmio_total=0x3011000 bar_sz=0x1000000 (XEN) HVM25: pci dev 03:0 INTA->IRQ5 (XEN) HVM25: Randy: pci_setup 0: mmio_total=0x3011100 bar_sz=0x100 (XEN) HVM25: Randy: pci_setup 0: mmio_total=0x3021100 bar_sz=0x10000 (XEN) HVM25: pci dev 04:0 INTA->IRQ5 (XEN) HVM25: Randy: pci_setup 1: mmio_total=0x3021100 pci_mem_start=0xf0000000 pci_mem_end= (XEN) HVM25: 0xfc000000 PCI_MEM_START=0xf0000000 PCI_MEM_END=0xfc000000 (XEN) HVM25: Randy: pci_setup 2: mmio_total=0x3021100 pci_mem_start=0xf0000000 pci_mem_end= (XEN) HVM25: 0xfc000000 (XEN) HVM25: Randy: pci_setup 3: low_mem_pgend:0x7f800 high_mem_pgend:0x0 reserved_mem_pgst (XEN) HVM25: art:0xfeff8 (XEN) HVM25: Randy: pci_setup: mmio_left: 0xc000000 (XEN) HVM25: pci dev 02:0 bar 10 size 2000000: f0000008 (XEN) HVM25: pci dev 03:0 bar 14 size 1000000: f2000008 (XEN) HVM25: pci dev 02:0 bar 30 size 10000: f3000000 (XEN) HVM25: pci dev 04:0 bar 30 size 10000: f3010000 (XEN) HVM25: pci dev 02:0 bar 14 size 1000: f3020000 (XEN) HVM25: pci dev 03:0 bar 10 size 100: 0000c001 (XEN) HVM25: pci dev 04:0 bar 10 size 100: 0000c101 (XEN) HVM25: pci dev 04:0 bar 14 size 100: f3021000 (XEN) HVM25: pci dev 01:2 bar 20 size 20: 0000c201 (XEN) HVM25: pci dev 01:1 bar 20 size 10: 0000c221 (XEN) HVM25: Multiprocessor initialisation: (XEN) HVM25: - CPU0 ... 46-bit phys ... fixed MTRRs ... var MTRRs [2/8] ... done.
