It’s a dick move to greet ALL new users with this, hoping to scare them to consider a subscription:<\/p>\n\n\n\n I don’t think frustrating people who are trying to learn\/explore the software will make them want to pay for a subscription. The best this dick move can do is to scare new users away as the user might think they did something wrong getting things they don’t expect. I certainly thought of throwing out Proxmox had there be better options out there when I run into this, as I’m still evaluating whether I should go with Qemu or Hyper-V.<\/p>\n\n\n\n First of all. This scary message doesn’t actually block you from using Proxmox. It’s just that you don’t get updates until you either pay for their enterprise repositories or change to the free repositories. At least you can still use the interface to gain shell access which we’ll need to fix it (or you can go to the physical computer and enter the same thing in the text terminal display locally)<\/p>\n\n\n\n The difference between enterprise and free is just which servers the update repositories points to. Getting the latest and greatest is not necessarily a plus for enterprise users so they let free users take the risks first and provide feedback so they can polish their software. Fair enough. Great model. <\/p>\n\n\n\n There are two parts to fixing this ordeal:<\/p>\n\n\n\n Basically, what you’ll need to do is to notice edit the lines file names show below (underlined in red) corresponding to the repository URL path you want to change:<\/p>\n\n\n\n bookworm is the latest Debian version’s code name at the time of writing<\/p>\n\n\n\n and obviously we pick the branch\/sub-folder that says no-subscription (there’s no enterprise here since it belongs to a different root URL), but you still have to get the name right for the ‘Components’<\/p>\n\n\n\n You can open it with a text editor like nano:<\/p>\n\n\n\n and edit this proxmox’s repository line (remember to skip the ‘ Ceph is an optional feature (not installed) yet it’s configured to be enterprise as well, so for consistency, we might want to change it to the no-subscription (free) version as well. The latest codename for ceph that was published at the time of writing is “quincy” (there’s nothing in the “reef” folder), so we click on it.<\/p>\n\n\n\n Again the ‘dists’ is boilerplate and not spelled out (so we don’t enter it) in the entries of the repository sources file.<\/p>\n\n\n\n bookworm is the current Debian version for that<\/p>\n\n\n\n and we see a “no-subscription” folder which is the one we want obviously. We can just guess by sensible names you’d choose if you were the developer.<\/p>\n\n\n\n You can again open a text editor like nano to edit the repository location file as shown in the web admin UI<\/p>\n\n\n\n And finally, disable Under the hood, it’s basically Proxmox adding a # (comment sign) to disable the line in Hit Reload and you are done with this subscription scare tactic.<\/p>\n\n\n\n Actually out of consistency, you can build your own There’s nothing fancy and hard-coded about these names. It’s basically the URL of where the update files are stored with an intermediate folder ‘ It simply looked like the developers for the web admin UI didn’t have the time to get to making the table entries clickable and editable yet and they merely got to make the enable\/disable button to comment out the lines in the file. You’ll see similar UI deficiencies in a lot of places later which you’d have to go to the shell to do it yourself after researching the concepts.<\/p>\n\n\n\n Even after you fixed the repository locations, it’s only per node, yet the nag screen is at the top admin UI level. The Updates\/Repositories interface won’t show error messages (undownloadable repositories) anymore, but the nag screen still needs to be addressed.<\/p>\n\n\n\n Luckily somebody wrote a script to deal with it<\/a>, hosted on Github:<\/p>\n\n\n\n This blog shows the mechanisms<\/a> in case if some changes broke the script above.<\/p>\n\n\n\n TAP interface is necessary for the ethernet card on the VM directly interact with the router connected to the physical hardware (PHY\/NIC) but with a different identity, which puts it at equal level as other physical computers on your network. This is often useful when you want to host servers.<\/p>\n\n\n\n I’ve adapted the instructions from Extremecoders on Github<\/a> here as the default ethernet device names are different<\/p>\n\n\n\n Since we are using the \/vmbr0 which is already set up, we can skip the bridge creation and adding the physical network card \/enp4s0 to the \/vmbr0 ‘bridge’ (virtual switch). <\/p>\n\n\n\n The core step is to create a TAP interface. Let’s call it \/tap0<\/p>\n\n\n\n You don’t need the “-u (username)” part unless you want to assign ownership of this specific TAP interface to a specific user.<\/p>\n\n\n\n Then you need to add this TAP (\/tap0 in this example) to the ‘bridge’ (\/vmbr0 in this example). ‘addif’ means ‘add<\/em><\/strong> i<\/strong><\/em>nterf<\/em><\/strong>ace’. ‘brctl’ means ‘br<\/em><\/strong>idge c<\/em><\/strong>ont<\/em><\/strong>rol<\/em><\/strong>‘<\/p>\n\n\n\n Make sure all the physical card (\/enp4s0), the TAP interface (\/tap0) and the ‘bridge’ (\/vmbr0) is up. Then assign IP to the ‘bridge’ \/vmbr0. If using acquiring new IP address from DHCP, use DHCP client (dhclient):<\/p>\n\n\n\n You can directly create the virtual hard disks directly from where you are configuring your VM, but you can only delete it from a Pool viewer. This is the same as VirtualBox. ‘local-lvm’ is a bunch of virtual hard drive images that you need to mount to act like a hard disk drive<\/a>. Your VM images lives in It’s a little more rigid than VirtualBox where you can directly point to the CD image. In Proxmox you have to upload the CD image to a pool before referring them in the VM’s settings. ‘local’ is just a folder of files (specifically Actually local and local-lvm are all defined at the root level called ‘Datacenter’<\/p>\n\n\n\n By default Proxmox choose x86-64-v2-AES for you, which might have better compatibility. I had trouble with the Windows port of Qemu not supporting hosts because my CPU is too new for it, but the Linux Qemu-Kvm have no trouble recognizing my new CPU under ‘hosts’ type. Look into the extra CPU flags to match whether you are using an AMD or Intel CPU. <\/p>\n\n\n\n <\/p>\n![\"\"](\"https:\/\/wonghoi.humgar.com\/blog\/wp-content\/uploads\/2023\/09\/image-28.png\")
