Subject [jira] [Commented] (CLOUDSTACK-1488) Ipv6 - When Vm is deployed as part of multiple networks, ne of the IPV6 address assigned to guest VM is lost.
Date Mon, 04 Mar 2013 18:35:13 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-1488?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13592465#comment-13592465
] 

Sangeetha Hariharan commented on CLOUDSTACK-1488:
-------------------------------------------------

I have confirmed that one of the IPV6 address is lost after  about ~2 hours.

The ipv6 address that is lost is the ipaddress that was not assigned automatically when I
started the Vm  (this issue tracked in CLOUDSTACK-1463).


>From router of the 1 st network that still has the Ipv6 address: I see the ipv6 request
being serviced every 1 hour from the the time the Vm was deployed.

> Ipv6 - When Vm is deployed as part of multiple networks, sometimes one of the IPV6 address
assigned to guest VM is lost.
> I have a Vm that is part of a dual network and ipv6 network.

eth0 is lost.
