[libvirt] [PATCH] doc: update description about user/group in qemu.conf

As a side effect of changes in the functions virGetUserID and virGetGroupID, the user and group configurations for DAC in qemu.conf are now able to accept both names and IDs, supporting a leading plus sign to ensure that a numeric value will not be interpreted as a name. This patch updates the comments in qemu.conf, including a description of this new behavior. --- src/qemu/qemu.conf | 19 +++++++++++++++++-- 1 file changed, 17 insertions(+), 2 deletions(-) diff --git a/src/qemu/qemu.conf b/src/qemu/qemu.conf index 18105ca..dd853c8 100644 --- a/src/qemu/qemu.conf +++ b/src/qemu/qemu.conf @@ -180,10 +180,25 @@ # guests will be blocked.
