Hi Justin, Thanks for your help.

Yes, I have checked the dependencies of openvswitch.ko, the results as below:

[root at localhost bai_ovs_2.5]# lsmod | grep openvswitch
openvswitch           258935  1 
nf_defrag_ipv6         34651  1 openvswitch
gre                    13808  1 openvswitch
nf_defrag_ipv4         12729  2 openvswitch,nf_conntrack_ipv4
nf_conntrack          101024  5 openvswitch,nf_nat,nf_nat_ipv4,iptable_nat,nf_conntrack_ipv4
libcrc32c              12644  3 xfs,btrfs,openvswitch
[root at localhost bai_ovs_2.5]# modprobe --show-depends openvswitch
insmod /lib/modules/3.10.0-123.el7.x86_64/kernel/lib/libcrc32c.ko 
insmod /lib/modules/3.10.0-123.el7.x86_64/kernel/net/ipv4/gre.ko 
insmod /lib/modules/3.10.0-123.el7.x86_64/kernel/net/netfilter/nf_conntrack.ko 
insmod /lib/modules/3.10.0-123.el7.x86_64/kernel/net/ipv4/netfilter/nf_defrag_ipv4.ko 
insmod /lib/modules/3.10.0-123.el7.x86_64/kernel/net/ipv6/netfilter/nf_defrag_ipv6.ko 
insmod /lib/modules/3.10.0-123.el7.x86_64/extra/openvswitch.ko

I have tried to rmmod these dependancies, but still faild. The error is shown "modprobe: FATAL: Module *** is in use” same as Openvswitch kernel model. 

I have tested uninstallation would be faild once I added an ovs bridge witch command "ovs-vsctl add-br br0", even though I have killed ovs-vswitchd and ovsdb procedure.
If I remove all ovs bridges with command "ovs-vsctl del-br", the uninstallation still faild.

I don't know what happened.

Thanks

You might check the log files.  You might also check "lsmod" and see if there's any dependency on it.
