Re: [libvirt] CAP_SYS_RAWIO missing for qemu-kvm device passthrough

Hi, I'm running current git libvirt on Fedora 13 beta. I enabled the use of libcap-ng as it is done in the regular F13 .spec. When I now pass a pci card through to a qemu-kvm guest using vt-d I get this error from qemu-kvm: Failed to assign irq for "hostdev0": Operation not permitted Perhaps you are assigning a device that shares an IRQ with another device? I'm running qemu-kvm as root. But that doesn't seem to be enough: I traced the issue down to a missing CAP_SYS_RAWIO.The kvm kernel module requires CAP_SYS_RAWIO to use the KVM_ASSIGN_DEV_IRQ ioctl.
