2 errors with latest Xen

2 errors with latest Xen

[Jun Koi]

Hi,

I use the latest Xen from hg repo to run 2 HVM here. I got the
problem: all these 2 cannot be started.

1) For a Vista VM: qemu-dm.log says that "/usr/lib/xen/bin/qemu-dm:
invalid option -- '-vncviewer' "
I can confirm that I have no vncviewer option in my configuration. So
this is very confused.

2) For Ubuntu VM: qemu-dm.log says that "-append only allowed with
-kernel option"
I can confirm that there is nothing strange in my config, as the very
same works with 3.3.1

How can I fix these problems?

Thanks,
Jun

It seems that for some unknown reasons, xen run qemu-dm with option
-vncviewer, and qemu-dm complains about that (then it failed to
start).

I notice that I dont have this problem with Linux HVM, but only with
Vista HVM. Is there any reason why xen behaves differently on Vista
and Linux HVM? (there is no difference between configurations)

Thanks,
Jun

The vncconsole option seems to be broken.
The following patch fixes the problem for me.

vncconsole is really the culprit. Thanks for the fix!!
