[9fans] Plan9 && qemu/Kqemu/qvm86

[Marco Mililotti]

Hi,
I'm new to the list (and relatively new to Plan 9).

Anyone that has installed P9 under Qemu using kqemu can give me infos 
about which kernel version (on the host), wich version of qemu/kqemu 
it's using?

As I'm trying to use Qemu to install the current P9 distribution I run 
into trouble: while using kqemu the startup process dies at the 
beginning (before seeing the "kfs... ..." line on the screen), with a 
"panic" message.

If I don't use kqemu, the process goes on, I can start the "copydist" 
task (but, hey, it's terribly *SLOW*).

Using the free kernel module (qvm86) for qemu allow me to proceed in the 
installation process :) and to start the "copydist" task, which however 
  dies while copying data (around 6% - 9%).

Some infos:
- host os: kernel 2.6.10-1.771_FC2 on Fedora Core 2
- qemu: 0.7.2
- kqemu: 0.7.2
- qvm86: snapshot of 2005-10-08

I've not found infos on 9fans about this kind of probles; any 
suggestions on what should I try?

Thanks,
PS:
booting the cdrom seems to be working fine without crashes.
well, is someone using kqemu at all here? For me plain qemu is working 
_very_ slowly (very! very! slowly on 1GHZ pc).

Plan 9 runs on it since 0.7.2.

A Qemu HDD image is on [0], with a preinstalled Plan 9, so the slow copy
process does not need to be done.

Still there is Xen, as the Xenoppix thread showed some days before. [1]

The copying is so slow. Running Qemu + Plan 9 on a 2.29Ghz Pentium IV is
fast enough for working with it.

Argh! I've to correct myself!
The boot went ok, but the system is unstable (under qvm86/qemu):
- man <smthg> give "troff: Stacksize overflow in n3; stdin: 5..."
- the little applic (top-left corner) that show stats about 
mem/interrupts/ctx switch/etc died with "stats 102: suicide: sys: trap: 
fault read addr=0x20 pc=...".

Under kqemu/qemu, also booting P9 on the CD (instead of choosing 
install) send the system in panic, with:
"panic: boot process died: sys: trap: fault read addr=0x0..."

While these errors are not - probably - due to problems of P9, It would 
be helpful to find how to succesfully run P9 into an emulator.

Hi,
thank you :) It's working.
However it seems that neither kqemu nor qvm86 accelerators are able to 
work with Plan 9 :/ (I've just tried with the suggested image I've 
downloaded).

Yes, but on 1Ghz it's not.
I'll look at xen, altought I cannot run gui with it.
Thanks.
