Nothing really specific, when I use virt-manager, on CPU type it doesn't have Ivy Bridge selection, I just wondering why. Sent from my BlackBerry 10 smartphone.

Either your virt-manager or your libvirt or your QEMU are too old. Kernel 3.17 supports up to Broadwell.

Interesting, is it depending on KVM or libvirt on CPU support? Sent from my BlackBerry 10 smartphone.

No, the reason could also be that for some reason we added Haswell and Broadwell, but forgot Ivy Bridge. I'll send QEMU patches next week.
