[Qemu-devel] qvm86 - datapoints

[Richard Neill]

Dear All,

Just to let you know a few results from my experiments with qvm86/qemu.
(I'm using all the latest CVS versions).

1)Trivial point, but the qvm86 README omits to say that it's necessary 
to run the install.sh script to put the qvm86.ko module in the right 
place. I also found it necessary to chmod 666 /dev/qvm86.

2)Attempting to start a WinXP image (which works unaccelerated in qemu), 
Windows refuses to start properly.

3)Attempting to start a knoppix iso, results in this error:
	Kernel panic: VFS: Unable to mount root fs on 01:03
(which I don't understand...)

4)And accidentally trying to run an image as root instantly panics the host.

Best wishes

Richard


P.S. Neither the qvm86 or the qemu websites make it very easy to find 
how to download the latest CVS sources - I think the links were quite 
well hidden!

Thanks.

This should happen when you do "make install", which the README does mention.

I saw this one while testing a recent patch, but then it went away. I'll check 
I haven't still got local patches.

I haven't seen this. I do most of my qvm86 testing as root.
