openstack无法创建虚拟机-提示dnsmasq问题
在使用dashboard进行创建实例时，后台nova日志报如下异常，导致虚拟机无法创建，后再次初始化nova数据库，依然如此：

不太清楚你的系统
升级下dnsmasq试试看？收起

出现上边异常后，我这边使用openstack-status进行查看相应服务，openstack-nova-network服务死掉了；而再使用service openstack-nova-network start进行启动，系统的messages日志里提示，该服务居然无法启动了：
Apr 9 18:53:01 fw6 kernel: ip_tables: (C) 2000-2006 Netfilter Core Team
Apr 9 18:53:05 fw6 dnsmasq[3298]: failed to set SO_REUSE{ADDR|PORT} on DHCP socket: Protocol not available
Apr 9 18:53:05 fw6 dnsmasq[3298]: FAILED to start up
。
后续我这边将Nova库重新初始化，重启服务器后，openstack-nova-network服务恢复正常。
但我再次使用nova network-create vmnet01 --fixed-range-v4=192.168.100.0/24 --bridge=br1 --bridge-interface=eth1 --multi-host=T --dns1=120.196.165.24创建完网络信息，再次创建虚拟机，nova、messages日志里的异常依旧。收起
