在openstack里启动openvswitch-switch服务service openvswitch-switch start的时候可能会出现 linux
ovs-brcompatd is not running的错误，解决方法以下： ubuntu
apt-get install openvswitch-controller openvswitch-brcompat
openvswitch-switch
aptitude install -y openvswitch-datapath-source aptitude install module-assistant
module-assistant auto-install openvswitch-datapath在这个过程当中可能还会出现以下错误：
Bad luck, the kernel headers for the target kernel version could not be found and you did not specify other valid kernel headers to use... api
这是头文件的问题， the kernel generic headers is missing the version.h file. ui
解决方法以下：ln -s /usr/src/linux-headers-`uname -r`/include/generated/uapi/linux/version.h /lib/modules/`uname -r`/build/include/linux/ spa
编辑 /etc/default/openvswitch-switch .net
BRCOMPAT=yes
在这事后若是仍是启动不了就强制加载： code
先移除网桥模块：rmmod bridge orm
