VM snapshots

+

VM snapshots require that there is at least on qcow2 disk attached to the VM +([VM Snapshots][qemu-doc-snapshot]).

+

Commands for qemu [Monitor][qemu-doc-monitor] or [QMP][qemu-doc-qmp]:

+
# List available snapshots.
+info snapshots
+
+# Create/Load/Delete snapshot with name <tag>
+savevm <tag>
+loadvm <tag>
+delvm <tag>
+
+

The snapshot can also be directly specified when invoking qemu as:

+
qemu-system-x86_64 \
+    -loadvm <tag>  \
+    ...
+
