This shouldn't need to touch qemu at all. This is a config option that should be parsed by xm/xend and passed directly off to hvmloader. Passing it via hvm_info_table would make most sense in my opinion. In which case you need to probably pass it as an optional param to xc.hvm_build() and poke it into hvm_info_table from that Python C wrapper function. If not specified, should you keep default behaviour and try to load all option ROMs? I'm not fussed - it's just a thought. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
