Re: [libvirt] computing the correct rom for seabios to recognize SR-IOV

Hi, I am a VDSM developer at Ovirt. Recently, we opened Bug 1224954 - seabios does not recognize a direct attached nic [1] and discovered that in order to leverage the <rom bar='on' file=FILE/> (as explained in [2]) in the hostdev element, one must compute the correct FILE path by following something similar to: $ lspci -v #loof for the VF nic part 00:08.0 Ethernet controller: Intel Corporation 82576 Virtual Function (rev 01) $ grep "82576 Virtual Function" /usr/share/hwdata/pci.ids 10ca 82576 Virtual Function $ rpm -ql ipxe-roms | grep 10ca /usr/share/ipxe/808610ca.rom This computation must be implemented for Ovirt to support booting a VM from PXE using a SRIOV VF. Is there any chance that this computation will be done automatically by libvirt?
