Hi,

Are you sure your hardware virt isn't disabled = in the BIOS? It is, in
my experience, the one BIOS setting the linux = kernel doesn't/can't
over-ride.

Properly.

It's usable, but slow. = VMWare was much faster.

And about the RAM issue. It's Windows = NT4. I don't think more is necessary.
The machine boots consuming = only 30MB. And about the slowness of the system
is during CPU = intensive operations.

Anything else to try = dudes?

On VMWare Player the performance was much = better. And this isn't a

Anyway; i'm launching the VM with this arguments:

Hi,

iirc the commandline = switch --no-kvm disables kvm (so it'S just software
emulated qemu). = You disable hardware virtualization accerleration = with
it.

Other than that: more than 128 MB ram will most = likely also help to
speed things = up.
