RE: Create GRE tunnel failed in 4.2 with XenServer.
Hey Tuna, (and anyone else working on this)
I filed bug 5967 which looks like it might relate to this - I was trying to use GRE tunnel isolation in 4.3 and got VM_REQUIRES_NETWORK errors from the XenServer when trying to start a new virtual router.
https://issues.apache.org/jira/browse/CLOUDSTACK-5967
What's the status of GRE Tunnel isolation as a feature at the moment?

Yes, my fixes will be put to 4.3 tomorrow! I get the flu today. Back to work tomorrow.

I need to make another patch to make GRE work with XenServer. Now just only
work with XCP and KVM, patch in master branch. I will push all of works to
4.3 as soon as possible.

Subject: Re: Create GRE tunnel failed in 4.2 with XenServer.
Hi guys,
Appologize for delay response. I just came back from Lunar New Year vacation.
I spent time to discover the GRE issue on XenServer 6.2. Now I know exactly the problem. Here is:
+ No problem with ovstunnel script, it works well with XCP, KVM and
XenServer.
+ The idea to create GRE tunnel between HOSTs is:
CloudStack scans all of VMs including VRs in the network (by NetworkID). On the first time, CloudStack calls ovstunnel to setup bridge, then all HOSTs know about that bridge. After that, CloudStack start creating and configuring GRE tunnels between couple of HOSTs in that network when starting VMs. The steps work excellent. However, in XenServer, the HOST (A, for example), which is called to create network (via XAPI call), already known about the network, but the other HOSTs (B,C,D, for
example) doesn't know about this network. So VMs can't start on B,C,D. It is VM_REQUIRE_NETWORK issue. CloudStack made a tricky to let B,C,D know about this network by plugging and unplugging immediately the VIF to the network from B,C,D Dom0. However, this tricky failed in XenServer version
6.2 because XenServer 6.2 don't accept the VIF from dom0 plug to network created by XAPI call. I still don't know why but I just think a way to fix it.
I see Murali's patch request. Will check it now.
Paul Angus: GRE tunnel works fine with XCP and KVM.
Again, sorry for delay response.
Thanks,
