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. For the ABI checks add avoidance for the genid comparison if the appropriate flag is set. Since adding support for a generated GUID (or UUID like) value to be displayed only for an active guest, modifying the xml2xml test to include virrandommock.so is necessary since it will generate a "known" UUID value that can be compared against for the active test.

  • failover in a disaster recovery environment
    • +
  • creation from template (import, copy, clone)
    • +
+ + 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. + +

+ When a GUID value is not provided, e.g. using the XML syntax + <genid/>, then libvirt will automatically generate a GUID. + This is the recommended configuration since the hypervisor then + can handle changing the GUID value for specific state transitions. + Using a static GUID value may result in failures for starting from + snapshot, restoring from backup, starting a cloned domain, etc.
