Én kvm-mel használom és 3.2.xx kernellel, de azt tapasztaltam, hogy az egy IRQ-n lévő összes eszközt át kell adni a pci-stub-nak. Azaz nálam: $ grep 20: /proc/interrupts 20: 62025 58372 IO-APIC-fasteoi ehci_hcd:usb2, uhci_hcd:usb3, uhci_hcd:usb6 Ha az usb2-t oda akarom adni a kvm-nek akkor az usb3-at és az usb6-ot is át kell adni a pci-stub-nak. -- Üdv, Zoli _________________________________________________ linux lista - linux@mlf.linux.rulez.org http://mlf.linux.rulez.org/mailman/listinfo/linux
