Hi all When I use pci-assign, I meet the following error: Failed to assign irq for "hostdev0": Input/output error Perhaps you are assigning a device that shares an IRQ with another device? Is it a bug or I miss something? I use libvirt to start the guest, and the user/group is root/root(not qemu/qemu). If I use the default qemu(provided in RHEL6.2), the guest can be started.
