Well, that's what I am asking. Is it useful, and if so, how?

In the past, I have had it installed on a regular partition using the host Intel core2duo, so I presume that I can specify -cpu core2duo to get the same environment in a virtual machine? > You don't need to specify -cpu parameter. It will be chosen automatically. I noticed that the argument was not mandatory, but I have been unable to determine whether there is any difference with or without it.

Clearly, this is not a project for a sunny, summer afternoon. _______________________________________________ virt mailing list [email protected] https://admin.fedoraproject.org/mailman/listinfo/virt
