Subjectgcc + kvm + 64 bit ? confused :-/

Hi all,


I'm a bit confused using the -march=xxx options for gcc when using a
kernel virtual machine...
Getting errors on smp when using the -march=nocoma for gcc... possibly
because smp is not fully supported yet I suppse.

I guess my question is, when installing kvm, is the virtual machine 64
bit capable or should I install 32 bit OS ?

I installed an amd64 debian image and it seems to be running
fine...except for the problem mentioned above.

And what type of architecture do i have to mention with gcc in a kvm ?
march ... arch...

thx !
