hello,<br>
<br>
im using kvm with virt-manager and i really like the interface you
provide.<br>
but i would like to know if there is a way to supply a romfile to a
passed through<br>
device like shown here.<br>

<b>VBIOS ROM access</b><br>
To re-run the POST procedures of the assigned adapter inside the
guest, the proper VBIOS ROM image has to be used. However, when
passing through the primary adapter of the host, Linux provides only
access to the shadowed version of the VBIOS which may differ from
the pre-POST version (due to modification applied during POST). This
has be been observed with NVDIA Quadro adapters. A workaround is to
retrieve the VBIOS from the adapter while it is in secondary mode
and use this saved image (-device pci-assign,...,romfile=...). But
even that may fail, either due to problems of the host chipset or
BIOS (host kernel complains about unmappable ROM BAR).

thank you in advance<br>
