[PATCH v2 02/86] machine: introduce ram-memdev property |
Date: |
Wed, 15 Jan 2020 16:06:17 +0100 |
Property will contain link to memory backend that will be
used for backing initial RAM.
Follow up commit will alias -mem-path and -mem-prealloc
CLI options into memory backend options to make memory
handling consistent (using only hostmem backend family
for guest RAM allocation).
