»Hi.How can I tell virt-manager to create a VM but with a CPU of an older generation? I am trying to play an old game with wine but I keep getting crashes. Something about UMIP and SIDTs and similar stuff.
I did some VM tinkering earlier this year. My recollection is that virt- manager offers a canned set of configurations, tailored to the host OS that you're installing. There's a "Customize before install" option that offers additional tinkering, IIRC it drops you into the same "Show virtual hardware details" tab for an existing VM, I don't recall if you can pick a CPU there, at this stage.
But once a VM is created, the "Show virtual hardware details" tab's "CPU" section is where you want to go. Untick the "Copy the host CPU configuration" option and you can pick a specific CPU to emulate.
