Subject: [PATCH v2 13/13] SUPPORT.md: write down restriction of 32-bit tool stacks
Date: Mon, 5 Jul 2021 17:18:58 +0200	[thread overview]
Message-ID: <ddff8b28-274d-d7fe-4ba9-0772859b7a72@suse.com> (raw)
In-Reply-To: <0bebfe8c-6897-dc8b-7fe0-9127d4996eb8@suse.com>

 ## Toolstack
 
+While 32-bit builds of the tool stack are generally supported, restrictions
+apply in particular when running on top of a 64-bit hypervisor.  For example,
+very large guests aren't expected to be manageable in this case.  This includes
+guests giving the appearance of being large, by altering their own memory
+layouts.
