The only thing I can think of is that something is wrong with my CFLAGS(but this is just an assumption). Any help would be appreciated Regards, YannisIt seems that KVM host is and AMD-based system. I suggest you to drop "-march=core2" from CFLAGS. Or if you do not plan to migrate this VM you can also try to replace it with something like "-march=amdfam10 -mno-3dnow". :)
I thought so... I now have to rebuild the whole world :) Is anyone aware of an -march value that can be used interchangeably between 64bit intel & amd cpus? The kvm host is not under my administration, so at any time my guest could be switched between hosts.
