Hi I'm interested in PCI passthrough support.
I downloaded Linux Kernel 2.6.28-rc7 and build and ran KVM (which is KVM-79) on this kernel. I started KVM with the following command-lines: $ qemu-system-x86_64 -boot c -m 512 -hda test.qcow -localtime -k en-us -pcidevice host=00:19.0 (00:19.0 is Intel(R) PRO/1000 Network Connection Device) However, KVM caused the following errors: Could not notify kernel about assigned device "00:19.0" register_real_device: Device or resource busy Segmantation_fault dmesg messages were as follows: $ dmesg [ 151.483167] [drm] Initialized drm 1.1.0 20060810 [ 151.525100] pci 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 151.525105] pci 0000:00:02.0: setting latency timer to 64 [ 151.525193] pci 0000:00:02.0: irq 505 for MSI/MSI-X [ 151.525309] [drm] Initialized i915 1.6.0 20080730 on minor 0 [ 187.854117] set status page addr 0x00033000 [ 823.246792] kvm: guest NX capability removed [ 823.311659] kvm: guest NX capability removed [ 823.487849] qemu-system-x86[5940]: segfault at 1dc ip 0807c446 sp 96420110 error 4 in qemu-system-x86_64[8048000+194000] [ 837.010304] kvm: guest NX capability removed [ 837.019163] e1000e 0000:00:19.0: BAR 0: can't reserve mem region [0xe0400000-0xe041ffff] [ 837.019163] kvm_vm_ioctl_assign_device: Could not get access to device regions [ 837.019194] kvm: guest NX capability removed [ 837.219560] qemu-system-x86[5944]: segfault at 1dc ip 0807c446 sp 9636b110 error 4 in qemu-system-x86_64[8048000+194000] I think that my cpu and my chipset maybe support VT-x and VT-d. http://www.intel.co.jp/products/desktop/motherboards/dq35jo/dq35jo-overview.htm CPU: Intel(R) Core(TM) 2 Duo CPU E6 chipset: Intel(R) Q35 Express Chipset Any advive or tips will help ?
