Hi Ilya,

This issue has previously been reported against Red Hat Enterprise Virtualization. It has been classified as a "request for enhancement" there - and will be prioritised as such for a future release.

Thanks for your report!
Dave.

there is using 4k mode, and being able to work with them which iirc was already fixed in a later version than node you are using.
