[jira] [Commented] (CLOUDSTACK-2209) added nics are not reachable
from other VMs on the same network
[ https://issues.apache.org/jira/browse/CLOUDSTACK-2209?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13642875#comment-13642875 ]
Marcus Sorensen commented on CLOUDSTACK-2209:
---------------------------------------------
What do you see when you look for the forward delay setting on your bridges? e.g.
brctl showstp cloudbr0
With RHEL/CentOS it's common for the foward delays to be high, like 14.99. This means that when a new NIC is plugged in, it doesn't work for 15 seconds, which may mean it's not getting its DHCP address in time.
Bridges created by cloudstack should be getting a proper forward delay, so check that.
Is there a chance these two VMs ended up on different physical hosts and the issue may lie there, or what does your environment look like? Just looking for additional clues.
