I have a server with a hosting company, Hetzner. The servers at this hosting company have a public IP, let's say, A.B.C.D/255.255.255.x. Additionally, one can order extra IPs like below: 1) additional subnet (let's say X.Y.Z.0 / 28) 2) single IP (let's say, E.F.G.H) With additional subnet, assigning the IP to libvirt guest is simple: - assign X.Y.Z.1 on the host - assign X.Y.Z.2 to the guest, with X.Y.Z.1 gateway - done, works fine. However, I'm having problems assigning a single IP to the guest (when there is no extra subnet on the host, but just an extra IP): - if I assign E.F.G.H/255.255.255.255 to the host, the IP is reachable from the internet - if I assign E.F.G.H to the guest (with a proper gateway), the guest is not able to communicate with the internet. Which networking mode should I use in this setup? Bridge, macvtap? I've tried both, without success (i.e. in macvtap mode, arp who-has are passed from the guest to the gateway, replies received on the host, but they are not passed to the guest). Has anyone ever set libvirt with a "typical" hosting provider, when only an extra IP, from a non-host subnet, is available for a guest? -- Tomasz Chmielewski http://wpkg.org _______________________________________________ libvirt-users mailing list libvirt-users(a)redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users
