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?
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.
