'vncdisplay=N' in hvm config file is ignored when building qemu-dm
arguments.
xm create or xm new -> xm start with hvm config file containing
vnc=1
vncdisplay=5
results in '-vncunused' being passed to qemu-dm. There are several
approaches
for a fix - this patch defaults vncdisplay to None in xm options. It
currently defaults to 1 and is always included in the image config
created by configure_hvm() in tools/python/xen/xm/create.py. In xend
(tools/python/xen/xend/image.py - parseDeviceModelArgs), vncunused takes
precedence over vncdisplay.
This patch is against 3.1.0-testing but looks like problem exists in
unstable as well - even with recent changes to
tools/python/xen/xend/image.py when moving to qemu 0.9.0
Regards,
Jim
