Xen Orchestra cannot connect XCP-ng Host by VPN-IPSEC
-
Hi:
We established a VPN-IPSEC between our Pool and a remote XCP-ng Host. We had a MPLS before change to IPSEC and the host was integrated to the pool. Now we cannot connect anymore.
It's "enabled" but we cannot reach its pool, so we cannot manage it nor see any VMS within it. Is there any port to deal? Any IPSEC setting to enable?Trying by XCP-ng Center is not better...
The log says just it, endlessly, no error message:
2024-03-14 17:20:53,926 INFO XenAPI.Session [Connection to 172.24.52.141] - Invoking XML-RPC method session.login_with_password 2024-03-14 17:20:54,733 INFO XenAPI.Session [Connection to 172.24.52.141] - Invoking XML-RPC method pool.get_all_records| can access the host normally, by SSH, for example.
Any ideas? -
@redbob365 The ideal approach here would be to setup an XO Proxy, for the Open Source edition, this isn't available. I believe you need premium to do so with XOA.
You could likely setup a proxy of your own to do manage remote XO Pools, without the need to setup multiple VPNs

If you have hardware that supports this you can try to do an openvpn Server as a TAP adapter. it will be closer to a Layer 2 MPLS connection than an IPSEC tunnel. I have no idea if XCP-NG or XO/XOA use any type of Multicast traffic to communicate. Thats the only thing I can think of unless you have IPSEC firewall policies blocking some type of traffic that XO needs. I presume you can ping/ssh into the remote host? Are these hosts using shared storage over the MPLS/IPSEC?
Edit:
I just found this as well.
https://xcp-ng.org/forum/topic/6609/unable-to-join-a-host-to-a-poolSeems to be also that the XCP-NG hosts will attempt to talk to each other over local URL's in some cases but I can't find a post about that. Bridging the two networks the same way the MPLS was would likely get you back to the way it was.
