I'm not sure if this is a virt-tools issue or a QEMU issue, but...
I hope to emulate a SandyBridge CPU on a host that has an Intel Core i3-2310M CPU. However, whenever I attempt to create such guest VM (whether a Windows guest or Linux guest) with an emulated SandyBridge CPU using virt-manager, I get the following error: "Error starting domain: unsupported configuration: guest and host CPU are not compatible: Host CPU does not provide required features: aes" (Details below.)
The i3-2310M CPU doesn't support AES (see link), and so I'm guessing that's the problem. However, I can emulate a Nehalem CPU on my i3-2310M host without any issues, which leads me to wonder: Why would aes be required for emulating a SandyBridge on an i3-2310M, but not required for emulating a Nehalem on an i3-2310M.
Does this requirement (aes for emulating SandyBridge) originate from virt-tools, QEMU or elsewhere? And whatever the origin, is there any workaround, short of buying a new laptop?
