Compiling error for amd64 on FreeBSD9.0 with XENHVM when include xen console driver.

[Wei Xu]

Sean,
Thanks for your comments.

Current I'm trying to investigate if I can porting the Console Driver to
Solaris.

I know the uart emulated by QEMU, but it's not my purpose to use it, I just
want to try the console driver with Hypervisor itself,  Must it bundle with
PV? Does XENHVM make sense too?

I am not familiar with how the console driver works by comparing to Qemu
serial,  so I'll be really appreciated if you can give some words about
that, thanks.

To verify it, I installed a new 32 bit i386 FreeBSD guest domain and
compiled the kernel with XEN support, that means already included the
console driver, but after I installed the new kernel, system can't boot up
after loaded the kernel, both the Xen and the Dom0 are 64 bit, so i guess
maybe it can't work for 64bit Hypervisor and Dom0, I wonder how can I
verify the console driver?

Regards,
Wei
