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?
Thanks,
Ido
