Am I correct in understanding that the VMs are doing the VLAN tagging in your scenario for the VM to VM traffic?

comment Openvpn, forward packets very slowly
When I'm troubleshooting vpn issues like this, I basically get 4 packet captures (after checking that CPU isn't bound up anywhere): 1) client inside, 2) client outside, 3) server inside, 4) server outside. On the client side, if you are pushing all traffic through the tunnel, then capture all the traffic. On the server side, filter to just that client's internal and external IPs, but don't filter any further.

Can you upload the tcpdump files in binary tcpdump format? This will make it easier to analyze in a tool such as wireshark (which makes this sort of debugging MUCH easier). Also, can you please tcpdump both the internal and external sides of the connection (simultaneously, if possible)? I.e. if you have packets to compare from tun0 and from eno1, it should be a piece of cake to figure out what is wrong.

Can you add cpu information from the client and server while the traffic is being transferred?

Apparently I misread it. I thought you were saying the opposite (which was reinforced by Karma's comment). I'll edit the answer appropriately.

comment Multiples ip address on interface. I want to specify one of them for output
I'm not saying there is a typo, I'm saying that it is doing EXACTLY what it is configured to do: use source IP of 212.83.129.104 when routing via the default route. If the question is "why is my traffic sourced from 212.83.129.104 instead of 88.190.15.135?", then the answer is "because it is configured that way, and your provider has a static route to send it back to you via 88.190.15.135". If you don't want it to do that, then change the configuration so it doesn't source from that IP.

I don't see how the above implies they are doing funky stuff with routing. It seems to me that the provider simply has a route that says "212.83.129.104 goes to 88.190.15.135", so they route traffic to that IP via the 88.190.15.0/24 network. If he sources his packets from 212.83.129.104, as it is configured to do, then they will come back to him just fine, no tricks or funny business.

comment Allocated Memory difference in xen guests with Linux 2.6.18 and 2.6.32
On question 1, in the section below where you have the text "despite showing", you then go on to show that dmesg is reporting "500984k/524288k". That means "500984k is available out of 524288k total". The free command also shows 524288k total mem, as per your output.

Centos 6.3 is also RedHat based, so will be different from Debian based (Ubuntu). Additionally, Centos 6.3 probably has different defaults compiled into the kernel than either 5.7 or Ubuntu, so it makes sense that it is different.
