Parallels Virtuozzo Containers (PVC) 4.7 for Linux fails to be registered in POA with the following error:

Task ID    645096
Task name    register HW Node with Agent IP
Task description    Task that register HW Node with ip
Queue status    Failed    
Start not earlier than    Sep-23-2011 12:48
Method name    taskRegisterHWNode on SCREF:VPSTasks:0
Last execution output    IP address 'fe80::21c:42ff:fed2:8803' is not valid.


The VPS Hardware Node PVC 4.7 for Linux cannot be registered if IPv6 support is enabled on the network interface.


1. Disable IPv6 support on all network interfaces on the VPS Hardware Node with the following command:# sysctl -w net.ipv6.conf.all.disable_ipv6=1
2. Execute the HW Node registration task.

3. Enable IPv6 support on network interfaces:# sysctl -w net.ipv6.conf.all.disable_ipv6=0
This issue is fixed in POA 5.3.
