>                 Key: CLOUDSTACK-4599
>                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4599
>             Project: CloudStack
>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the default.) 
>          Components: Network Controller, Network Devices, XenServer
>    Affects Versions: 4.1.1
>         Environment: Management server: CentOS 6.4 x86_64, CentOS Plus repo enabled,
 also pri/sec storage NFS server
> Hosts: XenServer 6.1, included OVS (1.4.2?)
> All the above running on ESX 5.1 (but I don't think it's a factor), with recommended
CPU and RAM configurations.

> Each hypervisor has two NICs, one on a public/management network, the other dedicated
to private/isolated traffic.  Both NICs (as xenbrX) have IP addresses and each host can reach
the other over the respective bridge IP addresses.   The bridge networks are labeled Public
(xenbr0) and Private (xenbr1).  The xenbr1 bridge IP subnet has no default gateway as it's
there only for the tunnel endpoints on each host.
> Guest networking is configured to be on the Private label, isolation type GRE.  In addition,
in Global Settings,
> sdn.ovs.controller = true and sdn.ovs.controller.default.label = Private.   I tried VLAN
(vNet) ranges of 1-4094 and 0-2147483647.   In the below example it was set to the latter
and picked 10960.
> BTW, it took quite a bit of scouring the net to find out how to config and what hypervisor
(XenServer only) GRE tunnels should work with, in 4.1.1.  Also, I'd prefer to use KVM but
understand that support is also in the process of being implemented. 
> I had initially tried using XCP 1.6 and received a different error, then realized XCP
support isn't yet finished.  I thought XenServer 6.1 should work though.  The xapiX bridges
are set up on the host and a vifX.Y appears to be added for the tunnel endpoints, then the
next step - I guess creating the tunnel itself, fails.  In this example, both the virtual
router and single isolated VM were on the same host... but I also could not migrate either
one, receiving a "VM requires network" error.  I won't provide details of that second error
right now, but can if desired.  Below is an excerpt of the management log
> Please let me know what other details to provide.   If desired, I can arrange access
to the vCloud Director system on which it's running, preferably via IPv6 and/or of course
collect more logs, run tests, etc.
