Add network drivers

[Farren]

I'm pretty new to Proxmox.....

I built myself a test server in a Lenvo desktop system and got two VM's running on it just fine.

I moved (a copy of) the drive to a Dell system in hopes that it would all "just work", but it didn't. It boots up fine but I have no networking.

Is there an easy way to install/update/fix the network drivers on a box that has no network?

Should I punt and just install a fresh copy on the Dell system and then move the two VM's??? And if so, what is the best way to move VM's? My 20+ years of experience with VMware is not helping me much with Proxmox!!

You should always use a fresh installation for such things.
If not: the interface is probably just called differently enpNNs0 vs eno1 vs ...
So you could use a live CD and do a

ip a

(locate your current interface on the new Host)
mount the root system and replace the interface in

/etc/network/interfaces

Edit: Also don't forget to replace the bridge-ports on the vmbr bridges.

Thanks!

I need to learn how to move VM's anyway, so maybe I should use this for practice.

Can I move VM's over the network if both servers are up at the same time and then shut down the original server? They're not very large, so I could also do it with USB drives.

You can also use an external HDD, backup the VMs to it and restore them to the new server, if the amount of data allows it

With NFS / Samba Share that is possible too.
Personally i would Backup on shared folder (NFS or Samba) and restore, if you can't use external HDDs (what is more easy than setup a NFS / Samba share).
