>From 550eb0c9662c027b6c8457498e3713f8d010e8db Mon Sep 17 00:00:00 2001 From: Liu, Jinsong <jinsong.liu@xxxxxxxxx> Date: Thu, 18 Mar 2010 22:50:29 +0800 Subject: [PATCH] Fix vcpu hotplug bug: get correct vcpu_avail bitmap Currently qemu has a bug: When maxvcpus > 64, qemu will get wrong vcpu bitmap (s->cpus_sts[i]) since it only get bitmap from a long variable. This patch, cooperate with another xend python patch, is to fix this bug. This patch get hex string from xend, transfer it to correct vcpu_avail bitmap which saved at an uint32_t array.
