Subject [jira] [Commented] (CLOUDSTACK-9759) VPC VR not obtaining ip address
Date Thu, 26 Jan 2017 18:26:24 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-9759?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15840173#comment-15840173
] 

Michael commented on CLOUDSTACK-9759:
-------------------------------------

Please let me know, if you need more logs.  ip addr on the VR only shows the link-local without
modifying (/etc/cloudstack/ips.json) and restarting the VR.

My understanding is the management server sends the json to the host and the host delivers
the ips.json to the VR.  Can I check something to see why ethNone is being passed instead
of eth1 at some point?

> My VPC VR is incorrectly be assigned ethNone inside (/etc/cloudstack/ips.json) for my
eth1 public network interface.  If I edit /etc/cloudstack/ips.json and change both occurrences
of ethNone to eth1 and restart the VPC then the network works for isolated guest networks
attached to the VPC VR and the VR itself.  (note: this issue only occurs with the VPC VR not
with guest network or guest shared networks).

> eth1 on VPC VR is the Public network interface
> Guest network uses vlan's 300-500 that are trunked into cloudbr1 on the host computer.
> I'm also attaching the /var/log/cloud.log from the VPC VR
> Note: I restarted the VR several times attempting other /etc/network/interfaces changes
before I read on how the VPC VR runs scripts to configure the nics, but the final restart
had the reflected changes that causes things to work.
> Cloudstack is using KVM hypervisor.
