Migrate Proxmox VM to XCP-NG¶

Make sure Xen Orchestra is already installed by following the steps in XCP NG and Xen Orchestra

Export Proxmox VM disk¶

1. SSH to the Proxmox host that is running the VM.
2. Get the path of the disk

   pvesm path vm:vm-100-disk-0
   

   where 100 is the VM ID and vm: is the storage in Proxmox.
3. Convert the disk to qcow2 format:

   qemu-img convert -f raw -O qcow2 /dev/vm/vm-100-disk-0 `vm_name`.qcow2
   

4. Convert generated qcow2 file to VHD format:

   qemu-img convert -O vpc <vm_name>.qcow2  <vm_name>.vhd
   

Import to XCP¶

1. Transfer the generated file to XCP host

   scp <file name>.vhd root@<xcp_ng_ip>:~/
   

2. Optional: Do a verification of the VHD file

   vhd-util repair -n </path/to/vhd_file>; vhd-util check -n </path/to/vhd_file>` . 
   

   The result should show the filename is valid.
3. Move the file to xcp local storage folder

   mv <vm_name>.vhd /run/sr-mount/<local storage uuid>/`uuidgen`.vhd
   

   To find out the storage uuid: cd /run/sr-mount and copy the folder name
4. Navigate to Xen Orchestra from a web browser, and go to Storage tab > Local Storage > Scan Disk. The new disk should be reflected there.
