Jumpy mouse in xen on Qubes-os

[GoogleCodeExporter]

Hello,

I've just installed 9front-3487.66db43ef6cd1.iso in xen on Qubes-os.  I am 
experiencing a jumpy mouse.  I beleive that the problem is not with my xen 
configuration, as the same configuration works fine for reactos, haiku, debian. 
 It also works fine within the installer for plan9 from bell labs(though after 
that version of plan9 is installed the mouse does not work at all.)  Anyways, 
I'll jump straight to the details:

As you can see in the screenshot, the mouse moves by long steps rather than 
fluidly.  That file was generated with the command "cat /dev/mouse > 
mouse-file-unformated" and then reformatted with sed.

My plan9.ini is very boring:
bootfile=9pcf
bootargs=local!/dev/sdC0/fscache
mouseport=ps2
monitor=vesa
vgasize=1024x768x16

Echoing various things to /dev/mousectl didn't help.  I tried everything 
liseted in the mouse man page, linear, accelerated, hwaccel on and off, res 0, 
1,2,and 3.  None seemd to have a positive effect.

What version of Xen?

What is the host OS, and what version?

I suggested using a non-vesa display, did you try this?

Alternatively, did you try any Xen options to turn off the (extremely hacky) 
mouse synchronization?

9front barely has enough manpower to support real hardware. A member of our 
community with extensive sysadmin experience -- he's worked his way up to 
administer a supercomputer -- says Xen stinks to high heaven, so why should we 
put time into this? You might get lucky here, someone may find he has the time 
and motivation to solve this, but given that drawterm is an effective 
workaround, I wouldn't be surprised if other things take priority.

If anyone does decide to work on this, I think our choices are either USB 
tablet support, (I know, USB stinks too,) or to find/make a display driver 
which Xen can provide and which has a hardware mouse cursor.

I get one of the /dev/realmode does not exist errors.  I didn't recompile 
anything though.
