From 743edef44f1d0da792aeb38a33bf468a4596f730 Mon Sep 17 00:00:00 2001 From: Ian Jackson Date: Wed, 23 Sep 2009 15:07:47 +0100 Subject: [PATCH] allow logdirty commands while paused (unbreaks 60dbe1+8f09f4) 60dbe1+8f09f4 breaks HVM live migration: 60dbe1 causes xc_save to attempt to disable logdirty mode while qemu is paused. 8f09f4 disables most commands, including logdirty, while the domain is paused. So xc_save times out waiting for qemu to respond to the logdirty disable command, and live migration fails. Logdirty commands issued while paused should not affect the stability of ioemu.
