  • How to Passthrough Physical Disks to Proxmox VE 8 Virtual Machines

    How to Passthrough Physical Disks to Proxmox VE 8 Virtual Machines

    Usually, virtual disks are used on Proxmox VE virtual machines. The virtual disks are partitioned and operating systems are installed. If you have a lot of virtual machines on your Proxmox VE server, you will be storing the virtual disks of multiple virtual machines on the same storage device, which will limit the storage bandwidth for the virtual machines. Usually, that’s how virtual machines are supposed to run and you will not have any problems with it.

  • How to Create a Private NAT Network Interface on Proxmox VE 8

    How to Create a Private NAT Network Interface on Proxmox VE 8

    By default, a bridged network is created in a new Proxmox VE installation. The default Proxmox VE bridge network assigns IP addresses to the virtual machines and LXC containers using the DHCP server of the router/switch your Proxmox VE server is connected to. So, all the virtual machines and LXC containers are accessible from your home/office network. You may not want that.

    If you want to put some of the Proxmox VE virtual machines or LXC containers in a private network, you have to...

  • Providing a license for package sources
    by Kasimba
    Arch Linux hasn't had a license for any package sources (such as PKGBUILD files) in the past, which is potentially problematic. Providing a license will preempt that uncertainty.

    In RFC 40 we agreed to change all package sources to be licensed under the very liberal 0BSD license. This change will not limit what you can do with package sources. Check out the RFC for more on the rationale and prior discussion.

    Before we make this change, we will provide contributors with...
