Hi, I am trying qemu-system-x86_64 on a x86 host running 2.6.30-2 (debian testing) kernel and trying to boot latest linus git kernel (x86). The kernel hang after printing the below [ 4.394392] ACPI: PCI Interrupt Link [LNKC] enabled at IRQ 11 [ 4.397837] virtio-pci 0000:00:03.0: PCI INT A -> Link[LNKC] -> GSI 11 (level, high) -> IRQ 11 [ 4.436489] ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 10 [ 4.439829] virtio-pci 0000:00:04.0: PCI INT A -> Link[LNKD] -> GSI 10 (level, high) -> IRQ 10 [ 4.462538] vda: [ 4.526913] input: ImExPS/2 Generic Explorer Mouse as /devices/platform/i8042/serio1/input/input3 [ 5.349554] async/1 used greatest stack depth: 5872 bytes left An earlier version of kvm booted fine the new kernel. So the vm disk image user space should all be fine. The older version of kvm that worked fine is QEMU PC emulator version 0.10.50 (kvm-devel) Any patches i need to try ? -aneesh -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
