resolved – Error: Unable to connect to xend: Connection reset by peer. Is xend running?

January 7th, 2015

Today I met some issue when trying to run xm commands on a XEN server:

[root@xenhost1 ~]# xm list
Error: Unable to connect to xend: Connection reset by peer. Is xend running?

I had a check, and found xend was actually running:

[root@xenhost1 ~]# /etc/init.d/xend status
xend daemon running (pid 8329)

After some debugging, I found it's caused by libvirtd & xend corrupted. And then I did a bounce of them:

[root@xenhost1 ~]# /etc/init.d/libvirtd restart
Stopping libvirtd daemon: [ OK ]
Starting libvirtd daemon: [ OK ]

[root@xenhost1 ~]# /etc/init.d/xend restart #this may not be needed 
restarting xend...
xend daemon running (pid 19684)

Later, the xm commands went good.

PS:

  • If you met issue like "resolved - xend error: (98, 'Address already in use')" when restart xend or "can't connect: (111, 'Connection refused')" when doing xm live migrate, then you can refer this article.
  • For more information about libvirt, you can check here.

 

Good Luck!
