OptionaldisableDisableFreePageReporting disable the free page reporting of memory balloon device https://libvirt.org/formatdomain.html#memory-balloon-device. This will have effect only if AutoattachMemBalloon is not false and the vmi is not requesting any high performance feature (dedicatedCPU/realtime/hugePages), in which free page reporting is always disabled.
OptionaldisableDisableSerialConsoleLog disables logging the auto-attached default serial console. If not set, serial console logs will be written to a file and then streamed from a container named guest-console-log. The value can be individually overridden for each VM, not relevant if AutoattachSerialConsole is disabled.
VirtualMachineOptions holds the cluster level information regarding the virtual machine.
