From c27ea3f9ef7c7f29e55bde91879f8514abce9c38 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Tom=C3=A1=C5=A1=20Golembiovsk=C3=BD?= Date: Mon, 12 Oct 2020 10:36:01 +0200 Subject: qga: add command guest-get-disks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add API and stubs for new guest-get-disks command. The command guest-get-fsinfo can be used to list information about disks and partitions but it is limited only to mounted disks with filesystem. This new command should allow listing information about disks of the VM regardles whether they are mounted or not. This can be usefull for management applications for mapping virtualized devices or pass-through devices to device names in the guest OS.
