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. -- View this message in context: http://xen.1045712.n5.nabble.com/virtual-bios-question-tp4427579p4427579.html Sent from the Xen - Dev mailing list archive at Nabble.com. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
