Hello, with the last update for virt-manager I have a Problem with my CPU (XEON- SandyBridge) I have to disable the CPU Flag "invts", afterward I can install a KVM Guest! Now with the coming upgrade to centos 7.1 in the virt-manager the CPU Flag config is missing and I can't install a KVM Guest anymore :-(. Is this a know BUG? -- mit freundlichen Grüßen / best Regards, Günther J. Niederwimmer
