Hi, when user create the virtual machine, then:
which code execute firstly, hvmloaer or qemu-dm?I have traced the codes flow
and found qemu-dm run before hvmloader,right?
And virtual bios code are both in hvmloader and qemu-dm, but I think it
should be only one of virtual bios
will be used to initialize the virutal device in qemu-dm.I find at the end
of hvmloader it will jmp to 0xffff0, that is the bios entry,so I think the
virtual bios in hvmloader will function. But how qemu-dm ingore the
execution of its virual bios inside?
Any one help me? Thanks.
