[Qemu-devel] [PATCH] QEMU Guest Agent: Add an interface to determine guest os type |
Date: |
Wed, 12 Apr 2017 19:10:56 +0800 |
vm management tools (e.g.libvirt) may tell if guest os is linux or windows,
so they can design a customized application accordingly, we suggest to add
an interface (guest-ostype) in QEMU.
