Public bug reported:
Hi,
The host processor is a 64 bit processor (as below)
When I run the emulated mode of 64 bit (full emulation) I can run the
64 bit OS fine. when I start using -enable-kvm, I get error message that
"Your CPU does not support long mode. Use a 32bit distribution."
trying to install SuSe linux enterprise server 64 bit

why is kvm not able to use 64 bit capability in a host which is a 64 bit
processor ?
