From ca039d02446698730d586df9ed3ba3fcd2c4bd98 Mon Sep 17 00:00:00 2001 From: "kaf24@firebug.cl.cam.ac.uk" Date: Mon, 19 Mar 2007 09:31:04 +0000 Subject: hvm: Fix platform-irq handling in presence of irqbalance daemon. The HVM guest did not respond when PV-on-HVM driver was tested on the following conditions. 1. RHEL4u4 2. vcpu 4 3. irqbalance on 4. pv-on-hvm driver used. Eventhandler did not work because IRQ was delivered to another vcpu by irqbalance.
