From cc38d68dc1d580fd9acc648e11057b1903ddb247 Mon Sep 17 00:00:00 2001 From: Michal Privoznik Date: Thu, 21 Nov 2013 16:34:40 +0100 Subject: [PATCH] virDomainReboot: Document that migration might be unsafe https://bugzilla.redhat.com/show_bug.cgi?id=744967 If a domain is rebooting and a migrate API is called meanwhile we would have to transfer the fakeReboot attribute to the destination in order to prevent domain doing plain shutdown over there. We shouldn't try to do anything clever about it other than documenting this as a known limitation.
