Hi Alexandre,
VXLAN on KVM works very well and we've had it in production for a number of years now. Please see this document on how it is implemented: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Linux+native+VXLAN+support+on+KVM+hypervisor Cloudstack does create all the VXLAN configuration for each new network, you just need to have a working underlay that supports multicast (e.g. an IP on the VXLAN interface and iptables rules rules that allow multicast traffic). We place our VXLANs into a VLAN and expose that VLAN via a KVM traffic label to the VXLAN guest network. - Si ________________________________ From: Alexandre Bruyere <bruyere.alexan...@gmail.com> Sent: Wednesday, November 14, 2018 10:32 AM To: users@cloudstack.apache.org Subject: Information on VXLAN implementations (and other guest isolation methods) Hello. I'm currently investigating guest isolation methods for a project. The idea was thrown about to use VXLANs, but it's rather fuzzy on how it actually is implemented. Does Cloudstack automatically create and maintain VXLAN connections, or does it ride off an already-implemented VXLAN system configured under the hood? And what would be the use cases for VXLANs? Would it be appropriate to use in a small-scale network for hybrid clusters? If not, what would the Cloudstack community recommend? Thanks for your time!
