I have "Intel(R) Core(TM) i5-3330 CPU @ 3.00GHz" on a physical host |
2 |
machine. I'd like to emulate a cpu with the "movbe" instruction set. |
3 |
Doing some testing, I tried, as root stuff like... |
4 |
|
5 |
qemu-system-x86_64 -enable-kvm -cpu Broadwell |
6 |
|
7 |
...and got the following warnings |
8 |

On real qemu sessions "grep movbe /proc/cpuinfo" doesn't get any hits. |
23 |
I hope I'm doing something wrong here, rather than qemu not being able |
24 |
to emulate a newer cpu. Any ideas? |
