  5. LXC loses network interface after a few days - possible solution found, but why?

    Hi, I have installed a Turnkey-fileserver (LXC) to create SMB/CIFS and NFS-shares with low resources and fast disk I/O instead of having to create a VM (also because I've read it's a bad idea to install those things directly on the host).

  11. [SOLVED] VMs not assigned IP via router DHCP, automatically assigned elsewhere

    Morning folks. I'm having a persistent problem with my VMs on Proxmox. For some reason, no matter how I set up static routes in my router, the VMs I make in Proxmox all seem to take whatever IP address they please. This is problematic as I'm migrating VMs from one computer to another and...
