Hi, This patch adds support for the -pcidevice host=bus:dev.func added in kvm-79 I used the structure as already defined in src/domain_conf.h so analog to usb one now can add pci devices as example: lspci: 06:02.0 Network controller: Eicon Networks Corporation Diva Server 2FX (rev 01) <hostdev mode='subsystem' type='pci'> <source> <address bus="0x06" slot="0x02" function="0x0"/> </source> </hostdev> values are hex so for bus: 0 to ff, slot: 0 to 1f and function: 0 to 7 Hope this patch is useful it applies to libvirt-0.5.1 and cvs checkout from today (with some hunks) Regards Jason -- Collax GmbH .
