<p>Hi list,</p>
<p>Can anyone advise me on the correct/best set up for Virtual
Server Hosting?</p>
<p>I have a guest in my server room wish to migrate to dedicated
server I rented in an offsite in a data centre. I rented a box
with one NIC and one public IP. I installed KVM on it and a
guest. (both Ubuntu 18.04 LTS server edition). I am struggling to
get the networking right.</p>
<p>Essentially I want the "Virtual Server Hosting" config mentioned
here: <br>
<a moz-do-not-send="true"
href="https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html-single/virtualization_administration_guide/index#sect-attch-nic-physdev">https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html-single/virtualization_administration_guide/index#sub-sect-routed-mode</a></p>
<p>I have not had any luck setting that up. It is listed in the
"Routed" section but the graphic says the virtual switch should be
in bridged mode. <br>
</p>
<p>I also tried using macvtap, and since I have only one guest was
expecting to be able to just use the host IP but it looks like the
data centre have restricted packets to the MAC address of the host
NIC. When set up I can ping the public IP (it is both eh host and
the guest?) but not their gateway. Should a macvtap not be
presenting the MAC address of the host NIC to the router and thus
allowing packets from the guest?</p>
<p>I clearly have a lack of understanding of how this is working and
how it is meant to work. When I tried the same thing on mt
hardware/network I can create myltiple guests that all use the
macvtap interface and I have no problems getting connectivity to
the outside world.</p>
<p>Before I approach the data centre about this I want to be sure I
understand what I am doing. I ultimately want to host a mail
server and several different web servers as guests all behind this
one host. I would alias their public IPs to the host NIC and use
IPtables to route traffic based on destination IP.<br>
</p>
<p>Does that make sense? Can anyone suggest the right way to achieve
this?<br>
</p>
<p>Please and thanks.</p>
