Perhaps the attached patch will fix the Issue2?
cs 18025 changed the size of vga ram, so we should reduce VGA_RAM_SIZE
to 4MB for ioemu-remote tree likewise.

Thanks,

With ioemu-remote, still failed to create hvm guest with vncviewer
disabled by 'sdl=1' or 'vnc=1 & vncconsole=0'. Two issues were found
with Xen #18039 as log pasted below.

BTW, will xen-3.3 release use ioemu-remote as default qemu? Looks there
would be some compatibility issues between xm/xend and ioemu-remote.

Issue1: if no vif option set. qemu exits with following log:
domid: 14
qemu: the number of cpus is 1
Unknown network device: user

Issue2: with vif option set, qemu exits with following log:
domid: 18
qemu: the number of cpus is 1
