To export a virt-manager snapshot (like the one shown in your screenshot) on Debian 13 (or any Debian-based system), you can use the virsh command-line tool, which is part of the libvirt suite. Here’s how you can do it:

---

Steps to Export a Snapshot

1. Identify the Snapshot Name

From your screenshot, the snapshot is named before_baidu. You can confirm this by listing all snapshots for the VM:

bash
Copy
virsh snapshot-list <vm_name> --all

Replace <vm_name> with the name of your virtual machine (e.g., Debian_trust_on_QEMU/KVM).

---

2. Export the Snapshot Configuration

Use the following command to export the snapshot’s XML configuration to a file:

bash
Copy
virsh snapshot-dumpxml <vm_name> <snapshot_name> > snapshot_before_baidu.xml

For your case:

bash
Copy
virsh snapshot-dumpxml Debian_trust_on_QEMU/KVM before_baidu > snapshot_before_baidu.xml

This will save the snapshot’s metadata (e.g., disk state, VM configuration) to snapshot_before_baidu.xml.

3. Export the Disk Image (Optional)

If you want to export the actual disk image associated with the snapshot, you need to locate the disk file (usually a .qcow2 file) and copy it manually.

• Find the disk path in the snapshot XML or the VM’s configuration:

  bash
  Copy
  virsh domblklist <vm_name>

• Copy the disk file (e.g., /var/lib/libvirt/images/debian_trust.qcow2) to your desired location:

  bash
  Copy
  cp /var/lib/libvirt/images/debian_trust.qcow2 /path/to/backup/

---

4. Recreate the Snapshot Later (If Needed)

To recreate the snapshot on another system:

1. Define the VM and its disks.
2. Restore the snapshot using:

   bash
   Copy
   virsh snapshot-create <vm_name> --file snapshot_before_baidu.xml
