cache and viodiskcache parameters in documentation

Hi, on chapter 6.13.1 "Live Migration Prerequisites" [1] of the RHV 4.2 Virtual Machine Management Guide, there is written: ____________ At a minimum, for successful live migration of virtual machines to be possible: [...] The migrating virtual machine must not have the cache!=none custom property set. ____________ However I can't find any custom property called "cache" under Edit Virtual Machine --> Custom Properties but only "viodiskcache". As a matter of fact, Appendix A of the same guide [2] reports the following statement: "If viodiskcache is enabled, the virtual machine cannot be live migrated" that suggest viodiskcache as the correct parameter. Are the two statements contradictory? Thank you. Stefano Stagnaro [1] https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/htm...

cache != none is a developer terminology for stating that it has to be none. So if it's defined to anything, migration is not possible. So they are the same. Y.
Thank you. Stefano Stagnaro
