Re: [libvirt] [PATCH V2 5/6] xenconfig: support bios=ovmf xl.cfg

Add support to xenconfig for conversion of xl.cfg(5) bios config to/from libvirt domXml <loader> config. SeaBIOS is the default for HVM guests using upstream QEMU. ROMBIOS is the default when using the old qemu-dm. This patch allows specifying OVMF as an alternate firmware. Example xl.cfg: bios = "ovmf" Example domXML: <os> ... <loader readonly='yes' type='pflash'>/usr/lib/xen/boot/ovmf.bin</loader> </os> An alternate OVMF firmware (from the one advertised in domaincapabilities) can be specified with bios = "ovmf" bios_override = "/path/to/my/ovmf.bin" Note that currently, Xen does not support a separate nvram for non-volatile variables.
