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.
Changes from v1:
- changed name of the interfaces (discard to release)
- fix make check error
- add more comments to qemu_iovec_release_ram()
- rebase on "Postcopy: Hugepage support" (David's patch series)
- removed ram_discard_page for xbzrle
- fix erroneous release memory in complete precopy (tie release-ram to postcopy)
Pavel Butsykin (3):
migration: add MigrationState arg for ram_save_/compressed_/page()
add 'release-ram' migrate capability
migration: discard non-dirty ram pages after the start of postcopy

Cosmetic patch. The use of ms variable instead of migrate_get_current()
looks nicer, especially when there reuse.

After the start of postcopy migration there are some non-dirty pages which have
already been migrated. These pages are no longer needed on the source vm so that
we can free them and it doen't hurt to complete the migration.

Hi Pavel,
I was curious, having merged this, how you're using postcopy; do you switch
into postcopy mode immediately or wait until the first sync or what?
Do you find yourself in postcopy mode long enough that it's worth
doing the release? If so on what size VMs are you working with?
Dave

Hi Dave,
I'm sorry it took so long, I was on vacation. And thanks for the quick
review and merge!
We want to use this function to update Qemu without rebooting VMs. It
looks like a local migration on the same host. Now, switching into
postcopy mode is done immediately, the size of VMs can be very
different.

Thanks! Do you have libvirt magic to do that update?

Yes, there are patches that add a flag "--local" for migration. The
flag adds start incoming VM and other magic about replacement source on
destination.
