Installing QEMU, KQEMU, and DHCP Patch

[zebarbu]

Little question on amd64:
In my Qemu, I can:
- boot dapper-i386 cdrom with or without kqemu
- boot dapper-amd64 cdrom WITHOUT kqemu
- boot dapper-amd64 cdrom WITH kqemu AND -smp 2

but I can NOT boot dapper-amd64 cdrom with kqemu as a mono-cpu (without the '-smp 2')...
And if I activate the "-smp 2", it is quite slow, so it is not a good choice...

Do you know how I may work around this?

wget http://exvision.net/qemu_mouse.patch

No connection to exvision.net. Where else can I get the patch?

I have tried this 4 or 5 times and I keep getting errors.

Is this correct? y

I kept getting that error until I chose not to install the CVS Unstable version. Just answer 'N' for that and it should work.

The CVS version doesn't work, but the other one does. However, it doesn't want to install kqemu. This is the error I get:

I am getting the following error while trying to install it:

Hi
Thanks for this great HOWTO.
I had one problem with compilng kqemu - the script seems to look for the "build" dir in the oldest /lib/modules/* directory (for me this is - "/lib/modules/2.6.15-20-386/") and not in the latest (for me this is - /lib/modules/2.6.15-25-386/).

The fix is to create a symbolic link to the "build" directory in the latest folder (2.6.15-25-386 in my case).

so just do (easy!)

cd /lib/modules/2/6/15-20-386

sudo ln -s /lib/modules/2.6.15-25-386 build

NB: Please substitute your own module directories - these were just the ones I have.
I hope this helps

Regards

everything works fine up until kqwmu i get this:

what should i do?

[tzulberti]

Thanks squilla, that solved the problem that I was having. The script is great. Also a y/n or yes/no would be appreciated.

Thanks.

I uploaded yesterday's CVS here, it is compiled to support KQemu.
