Great.
Ok i see 3.10 was released 2013-06-30, so looking for a cpu released the
previous year, say
IvyBridge, IvyBridge-IBR Intel Xeon E3-12xx v2 (Ivy Bridge, 2012)
and $ qemu-system-x86_64 -cpu ? | grep -i ivy
x86 IvyBridge (alias configured by machine type)
x86 IvyBridge-IBRS (alias of IvyBridge-v2)
x86 IvyBridge-v1 Intel Xeon E3-12xx v2 (Ivy Bridge)
x86 IvyBridge-v2 Intel Xeon E3-12xx v2 (Ivy Bridge, IBRS)
So if I run the following then RHEL will think it's running on an IvyBridge
cpu, right?
$ qemu-system-x86_64 -cpu 'x86 IvyBridge-v1' etc
