Re: [Xen-devel] VMX Assist and x86 segment registers
Anthony Liguori wrote:
vmxassist is the source of the problem here though as it uses vm86
mode which means that there is no way to get at the hidden cpu
state. If we moved to a model where all 16-bit code was emulated
by qemu, we would have access to all the hidden cpu state.
There are fewer problems in 32 bit mode since the segmentation
stuff is mostly visible so there shouldn't be a problem in handing
off from the 16 bit emulator to to direct 32 bit execution.
I completely agree. If there's anything I can do to help, e.g.,
running code in during development, please let me know.
