Export/ Import VM to/from a backup file using command line on XenServer Rumi, April 18, 2021 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 The following items are about to be destroyed VM : 1fcc437b-b792-d609-925a-a700be870dff (Debian Jessie 8.5 - Export) VDI: 3c2ca807-8654-468d-98e2-dec8fb7513b8 (0) Type 'yes' to continue yes All objects destroyed Related XCP-NG XCP-NGXen
