Key: CLOUDSTACK-1461
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1461
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Reporter: Sangeetha Hariharan
Ipv6 - From a Vm that that is part of 2 networks, Name resolution fails for Vms
that are part of non default network fails
Steps to reproduce the problem:
Create a dual stack network ,N1
Create a dual stack network, N2.
Deploy a VM - vm1 in N1 and N2.
Deploy a VM - vm2 in N2.
>From vm1 , try to reach vm2 using the vm-name.
DNS name resolution fails.
/etc/resolv.conf does not have the IPV4 address of the router that belongs to
non default networks.
It does have the IPV6 address of the router that belongs to non default
networks.But seems like it is not being used for name resolution.
