qemu-kvm: Migrate: socket bind failed,qemu-kvmmigrate




1、错误信息

qemu-kvm: Migrate: socket bind failed

2、原因:

其原因是qemu迁移端口与glusterfs端口冲突导致的

3、解决方法:

这种问题有两种解决办法:

第一:

解决办法,在所有安装glusterfs的机器上执行:
# vi /etc/glusterfs/glusterd.vol
在“end-volume”之前加入一行:
option base-port 50152  (写其它端口也可以,反正不要写49152)

然后,重启glusterfs服务

第二:

# virsh migrate --live rhel qemu+ssh://10.66.100.102/system --verbose
error: internal error Process exited while reading console log output: char device redirected to /dev/pts/2
qemu-kvm: Migrate: socket bind failed: Address already in use

4:do migration
5:repeat 20 times, no error occured.
S2:
1:prepare a guest same with S1
2:do live migrate then cancelled
# virsh migrate rhel qemu+ssh://10.66.100.102/system --verbose
Migration: [  2 %]^Cerror: operation aborted: migration job: canceled by client
3:before migration canceled, check port on dst.:

after canceled, check port again:
# netstat -laputen | grep 49153
no output
if cancelled the job, the port cleaned up, can reused in next migration
S3:
1:config /etc/libvirt/qemu.conf, edit and restart libvirtd
migration_port_min = 51152
migration_port_max = 51251

2:do migration
3:check dst. port

migration worked well.


tomcat 60 启动就报错 ,Socket bind failed: [730049] ???

应该是重启下电脑就好了,有一些进程占用8080端口,没有停止
 

解救 Socket bind failed:【730048】

是不是你的防火墙阻止也端口的使用?
先把防火墙关了试一下吧。
