XCP-NG Resize VM Disk¶

Reference Technically, resizing using XOA is simply provisioning more physical resource. That being said, we also need to resize the VM partition, otherwise the OS won't recognize the change.

Step 1: Adjust the disk size via the XOA vm tab
Step 2: Setup the boot order, load ISO DVD, and boot into live OS
Step 3: Use Gparted (already installed) to resize the partition
Step 4: Eject the ISO dvd
Step 5: Reboot
