[Qemu-devel] [PATCH 0/2] migration capability to discard the migrated ram pages

[Pavel Butsykin]

This feature frees the migrated memory on the source during postcopy-ram
migration. In the second step of postcopy-ram migration when the source vm
is put on pause we can free unnecessary memory. It will allow, in particular,
to start relaxing the memory stress on the source host in a load-balancing
scenario.

Pavel Butsykin (2):
  add 'discard-ram' migrate capability
  migration: discard non-dirty ram pages after the start of postcopy
