Learn how to install and run XPEnology DSM 7.2 on Proxmox VE using the ARC Loader, without any USB boot. This step-by-step tutorial shows how to create the VM, attach the ARC loader image, and boot Synology DSM directly inside Proxmox. Perfect for testing or home lab Synology setups. 1. On Proxmox Lab: VM ID 121, upload arc img local (zfs), Minimum disk capacity 2Gb (recomment 10Gb). Note Network VM: E1000 Step 1: Create VM Step 2: Write img location: local-zfs dd if=/var/lib/vz/template/iso/ of=/dev/zvol/rpool/data/vm-121-disk-1 bs=4M status=progress location: local (ext4) dd if=/var/lib/vz/template/iso/ of=/var/lib/vz/images/102/ bs=4M status=progress location: local-lvm (ext4) dd if=/var/lib/vz/template/iso/ of=/dev/pve/vm-102-disk-1 bs=4M status=progress • if= is the ARC loader ISO/IMG file you uploaded to the ISO folder. • of= is the path to the virtual disk file you want to “flash” the ARC loader into. • bs=4M helps to write faster. Step 3: Setup NAS Step 4: Setup Interface IP 2. On a physical drive running Linux Step 1: Copy the ARC img file to a temporary Linux machine (Ubuntu live or Proxmox shell are both fine). Step 2: Run the command to write to disk dd if=/path/to/ of=/dev/sda bs=4M status=progress sync Note: /dev/sda here must be the SSD you want to use as boot. Check carefully with lsblk or fdisk -l to avoid writing to the wrong data drive. 3 On a physical drive running Windows Step 1: Download Win32DiskImager and install. Step 2: Open the app in the Image File box, select . In the Device box, select the correct SSD (e.g. \\.\PhysicalDrive2). Check carefully in Disk Management ( ) to avoid writing to the wrong Windows drive. Click Write → wait a few minutes → Done. #Proxmox #XPEnology #SynologyDSM #ARCloader #ProxmoxTutorial #Homelab #Virtualization #NAS #DSM7 #ProxmoxVE
