File 009-cli-cpu-Add-maxphysaddr.mode-bits-options.patch of Package virt-manager
Subject: cli: --cpu: Add maxphysaddr.{mode,bits} options From: Lin Ma lma@suse.com Fri Aug 19 18:18:50 2022 +0800 Date: Sat Aug 20 10:03:11 2022 -0400: Git: fbdf05162606e4d70506b65d0dd647a59f229253 This commit added support for cpu physical address bits control, It's useful for VMs with huge amount of ram.
