We run our dev testing machines on 4C, 16GB Memory & only a couple GB of disk. But the problem here is, that our machine is based on an AMD 5700G, which is roughly 50-70% faster. If you have any recommendations how we can represent it better, feel free to write me 🙂 The new IP is probably due to your DHCP server not allocating static IP's for the same MAC address. You can still setup a static ip, by using systemd-network files on flatcar:

[Match]
MACAddress=<MAC_ADDRESS_OF_YOUR_NETWORK_ADAPTER>

[Network]
Description=Static IP address for flatcar

Address=<IP_ADDRESS>/<SUBNET_MASK>
Gateway=<IP_OF_YOUR_GATEWAY>
DNS=<PREFERED_DNS_SERVER>

Put this file into /etc/systemd/network with a name like 00-staticip.network and reboot the machine (or restart systemd-networkd). More information is also available here: https://learn.umh.app/course/how-to-change-networking-in-flarcar/
