When pc-sysfw.rom_only == 0, flash memory will be
usable with kvm. In order to enable flash memory mode,
a pflash device must be created. (For example, by
using the -pflash command line parameter.)
Usage of a flash memory device with kvm requires
KVM_CAP_READONLY_MEM, and kvm will abort if
a flash device is used with an older kvm which does
not support this capability.
If a flash device is not used, then qemu/kvm will
operate in the original rom-mode.
