The value is used to help notify the guest operating system when the virtual machine is executed with a different configuration. This patch adds support for a new "genid" XML element similar to the "uuid" element. The "genid" element can have two forms "" or "$GUID". If the $GUID is not provided, libvirt will generate one and save it in the XML. Since adding support for a generated GUID (or UUID like) value to be displayed modifying the xml2xml test to include virrandommock.so is necessary since it will generate a "known" value.

+
Since 4.4.0, the genid + element can be used to add a Virtual Machine Generation ID which + exposes a 128-bit, cryptographically random, integer value identif= ier, + referred to as a Globally Unique Identifier (GUID) using the same + format as the uuid. The value is used to help notify + the guest operating system when the virtual machine is re-executing + something that has already executed before, such as: + +
    +
  • VM starts executing a snapshot
    • +
  • VM is recovered from backup
    • +
  • VM is failover in a disaster recovery environment
    • +
  • VM is imported, copied, or cloned
    • +
+ + The guest operating system notices the change and is then able to + react as appropriate by marking its copies of distributed databases + as dirty, re-initializing its random number generator, etc. + +

+ The libvirt XML parser will accept both a provided GUID value + or just <genid/> in which case a GUID will be generated + and saved in the XML. For the transitions such as above, libvirt + will change the GUID before re-executing.
