Export/ Import VM to/from a backup file using command line on XenServer

Identify VM’s UUID

We start by identifying a virtual machine we would lake to export to as a regular backup file. Run xe vm-list to list all available virtual machines and take a note of the virtual machine in question:

# xe vm-list
uuid ( RO) : 7371124f-7d4d-66b7-cbc7-a98b1457543e
name-label ( RW): Debian Jessie 8.5
power-state ( RO): halted

uuid ( RO) : bad8e456-df88-435d-ba12-3f0f6e54b2c6
name-label ( RW): Control domain on host: xenserver
power-state ( RO): running

Take VM snapshot

At this stage we take a snapshot of our virtual machine. The UUID of the target VM is eg. 7371124f-7d4d-66b7-cbc7-a98b1457543e:

# xe vm-snapshot new-name-label="Debian Jessie 8.5 - Export" vm=7371124f-7d4d-66b7-cbc7-a98b1457543e
1fcc437b-b792-d609-925a-a700be870dff

Snapshot with name Debian Jessie 8.5 – Export has been taken.Export VM to a file

Now is a time to export our VM into a file:

# xe vm-export vm=1fcc437b-b792-d609-925a-a700be870dff filename=debian_vm.xen
Export succeeded
# ls -lh debian_vm.xen
-rw------- 1 root root 1.5G Sep 16 17:27 debian_vm.xen

Import VM from a file

The file created in the previous step can now be used as a base to import new XenServer virtual machines:

# xe vm-import filename=debian_vm.xen
dc1c72bb-3a53-9335-669a-6e68a7f99873

The new virtual machine with UUID dc1c72bb-3a53-9335-669a-6e68a7f99873 has been created.

# xe vm-list
uuid ( RO) : dc1c72bb-3a53-9335-669a-6e68a7f99873
name-label ( RW): Debian Jessie 8.5 - Export
power-state ( RO): halted

uuid ( RO) : 1fcc437b-b792-d609-925a-a700be870dff
name-label ( RW): Debian Jessie 8.5 - Export
power-state ( RO): halted

uuid ( RO) : 7371124f-7d4d-66b7-cbc7-a98b1457543e
name-label ( RW): Debian Jessie 8.5
power-state ( RO): halted

uuid ( RO) : bad8e456-df88-435d-ba12-3f0f6e54b2c6
name-label ( RW): Control domain on host: xenserver
power-state ( RO): running

Remove the snapshot

Optionally you can now remove the unused snapshot to conserve some disk space:

# xe snapshot-uninstall snapshot-uuid=1fcc437b-b792-d609-925a-a700be870dff
