[Xen-devel] [PATCH] [RFC] Intercept some xm commands on HVM
Hello! I find some of the xm commands when applied to an HVM domain misleading: xm shutdown - behaves like ''xm destroy'' unlike the paravirtualized case that gracefully shuts down a domain; use ''destroy'' instead for HVM xm migrate / save - returns Error: /usr/lib/xen/bin/xc-save ... failed The attached patch intercepts only those commands now and returns a ''better'' message.

We need a decent mechanism for guest capability interrogation, that''s for sure, so that we can give better diagnostics; I''d like to see this mechanism in Xen 3.0.4. For now, I don''t think we can reject these commands unconditionally.
