RaspiBlitz in a Proxmox VM

[openoms]

Just had a successful RaspiBlitz install in a Proxmox VM. Install went very smooth and had no issues. I'm running Proxmox VE 8.1.3 and used Debian 12.2.0 for the VM. Hardware is a Ryzen 5700g, 32GB DDR4 RAM, and a Samsung 990Pro 4TB NVME SSD.

Steps taken

1. Setup the VM in Proxmox to install Debian, CPU set to Host, and allotted a 64GB drive on the 990Pro to emulate the SD card.
2. Started the VM and installed Debian with no GUI.
3. Booted into the VM, switched to root and installed sudo with ' apt install sudo '
4. Downloaded the RaspiBlitz build script with ' wget https://raw.githubusercontent.com/rootzoll/raspiblitz/dev/build_sdcard.sh '
5. Ran the build script with ' sudo bash build_sdcard.sh -f true -b dev -d headless -t false -w off '
6. When the script finished the install I shut down the VM.
7. Configured a second 1.5TB SSD on the 990Pro for the VM to emulate the data drive and restarted the VM.
8. SSH into the VM and the setup took off just like on the Raspberry Pi 4.

So far I have Electrs, Mempool, JoininBox, and C-Lightning running successfully. I have Zeus connected to the node as well. Happy to say this install was completely painless and it runs MUCH faster than on the Pi. Just thought I'd share my experience.

the CLN upgrade was premature, will be done in PR #4281
the dev branch should be working now if you try again

Build failed again?

err='baseimage not supported'

[Silarous]

I received that same message at the end of the build. It should still work. Just reboot and make sure you SSH in with the username ' admin ' and password ' raspiblitz '

[alex27riva]

Are you using a physical drive or internal storage for the data?

[Silarous]

My main drive and data drive are both on the 990Pro NVME that is in the m.2 port on the motherboard. Also passed through a 8gb USB stick for the emergency backup.

would suggest to not use fatpack for your build. The base image does not need to contain all that, on amd64 compiling things doesn't take that much.
use the option: -f false

Just updated the VM install to the latest RaspiBlitz release v1.11.0. Steps taken

1. Selected Update -> Release in the RaspiBlitz menu, downloaded the Lightning backup, and shut the machine down.
2. Added a CD drive to the VM and loaded the Debian 12 Bookworm ISO. (This Raspiblitz release is used with Debian 12)
3. Changed the boot order to boot from the CD drive first.
4. Started the VM and installed Debian to my smaller 64GB drive writing over the old data and shutdown the VM. (Don't write over your data drive!)
5. Removed the CD drive from the VM.
6. Started the VM, switched to root and installed sudo/wget. "apt install sudo wget"
7. Downloaded the build script. "wget https://raw.githubusercontent.com/rootzoll/raspiblitz/dev/build_sdcard.sh"
8. Ran the build script. "sudo bash build_sdcard.sh -f false -b dev -d headless -t false -w off"
9. Restarted the VM and SSH into it with admin:raspiblitz.
10. It found my data drive and began the restore process!

One thing to note, I have a USB drive added to this VM for a SCB/Emergency-Backup. On my first attempt at this upgrade, I left the USB drive attached and when I first booted into the new RaspiBlitz install, it thought my USB drive was my data drive, formatted it, and wouldn't restore my old system state as a result. I repeated the process with the USB drive detached and it found the correct 1.5TB data drive. Once it was done, I reattached the USB drive, enabled the USB backup, and all was well. Overall a painless upgrade!
