kvm 安装完成查看自己建的网络virtbr0没了,ifconfig 后果然没了virbr0
=============================================================
然后尝试 virsh net-start default,又得到dnsmasq的错误:
error: Failed to start network default error: internal error Child process (dnsmasq --strict-order --bind-interfaces
--pid-file=/var/run/libvirt/network/default.pid --conf-file= --except-interface lo --listen-address 192.168.122.1 --dhcp-range 192.168.122.2,192.168.122.254
--dhcp-lease-max=253 --dhcp-no-override) exited with status 2.
=========================================================
/var/log/message

【思路分析】
经过google查找资料
发现你要是单独安装dnsmasq和libvirt就会出现这个问题....
具体的扯皮在https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/231060
两边的人都不愿意改....但是提供了解决方案:
Following advice in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=505522 We could for example have:
/etc/dnsmasq.d/libvirt bind-interfaces except-interface=<virtual bridge>
and libvirt would start its dnsmasq using --interface=<virtual-bridge>
最终我使用的方法，dnsmasq和libvirt全部移除，重新一起安装。
【解决步骤】
[root@cloud001 ~]# yum remove libvrit-python libvirt dnsmasq
[root@cloud001 ~]#shutdown -r now
[root@cloud001 ~]# yum -y install libvrit-python libvirt dnsmasq
[root@cloud001 ~]#/etc/init.d/libvirtd restart
[root@cloud001 ~]#/etc/init.d/dnsmasq restart
[root@cloud001 ~]# chkconfig libvirtd on
[root@cloud001 ~]# chkconfig dnsmasq on
[root@cloud001 ~]# /etc/init.d/network restart
