You will most likely need to run apt-get -y install git make to check out this repo.

Make sure you can access the console of this machine to fix any mistakes you might make with the network configuration. If this is a server, you should be able to use ipmitool lan print to see the IP address of the remote console, and use that.

Unless you are planning on doing GPU passthrough, make sure things like 'VT-d' and 'SR-IOV' are disabled in the BIOS of the host.

Decide how you are going to do your networking between hosts, vms, containers, and the internet. Usually a simple bridged connection is sufficient, which is in the example configuration installed below.

Network cards should almost never be passed through to a client, unless that client is a dedicated router that is running DPDK or XDP itself, and you are expecting that VM to route more than 1m packets per second (Normally for that usage it would be on dedicated hardware anyway, for reliability).

The first time make proxmox is run, it will place some example interface files in /etc/network/interfaces and then exit. You can use those to prepare the host for the standard proxmox network configuration.

You should copy /etc/network/example.interfaces into place, and configure it to match your network layout.

There is almost no reason to use OVS for host connectivity, and is actively discouraged if you are planning on using LACP (802.3ad). It is purely provided because some people want to try it!

There is an example /etc/network/example.interfaces.ovs file created, which you can use as a template to replace your current interfaces file.

After you have done that, CHECK YOU CAN GET IN VIA OUT OF BAND ACCESS Obviously, if you're right in front of the machine, you can use the physical keyboard and monitor!

You can now run make proxmox again, and it will prepare the machine for use. It will error if eth0 does not exist (which it should not), and you should now reboot (after configuring /etc/network/interfaces) the host.

If you correctly updated the interfaces file, everything should just work. Otherwise edit it again via the console and run ifdown -a and then ifup -a to reapply the network changes.

The second time you run make proxmox the rest of the machine will be configured, enabling kexec and other tweaks.

There may be a slight race condition when enabling kexec - you can run make proxmox a second time to make sure kexec is loaded and ready, and then reboot the machine to make sure it does a kexec reboot, instead a full reboot.
