From 0dad1ec009d8498c91e93ac31582a42e4b4bf9a0 Mon Sep 17 00:00:00 2001 From: Peter Krempa Date: Fri, 15 Nov 2024 10:00:25 +0100 Subject: [PATCH] kbase: virtiofs: Clarify migration support statement virtiofs 1.11 contains support for migration so update the 'Note' which states that migration is not supported. Additionally mention that VM snapshots don't save state of the files shared via virtiofs so reverting is not a good idea.
