Error "sslerror: (8, 'EOF occurred in violation of protocol')" When Configuring HA on Oracle VM (Doc ID 1210923.1)

Last updated on AUGUST 04, 2018

Applies to:

Oracle VM - Version: 2.2.1 and later   [Release: OVM221 and later ]
Linux x86-64


You add the manager's IP address to 'allow=' list when configuring the ovs-agent, e.g.:

# service ovs-agent configure
;network access control by ip --
;rules := if addr.match(allow) and not addr.match(deny): return True
;pattern items delimited by comma and could be
;   #single ip
;219.142.73.*    #range
; #range in CIDR format
;default to allow all, deny none
where x.x.x.x is the IP address for manager server.

After restarting the ovs-agent, you get errors when trying to set up HA:
"2010-09-15 17:08:52" ERROR=> ha_check_agent_version: failed. => <Exception: get srv('hvovm01') agent version failed! => <sslerror: (8, 'EOF occurred in violation of protocol')>

  File "/opt/ovs-agent-2.3/", line 196, in ha_check_agent_version

Run 'service ovs-agent configure', and add the manager's IP address to 'allow=' list
