[Qemu-devel] [PATCH v5 0/5] don't use NVDIMM for balooning

[Vladimir Sementsov-Ogievskiy]

v5: do not use qapi
 0002-0004: new patches
 0005: white list instead of black list

v4:
 0001: Reviewed-by: Eric Blake <address@hidden>
 second patch is splitted to 0002 and 0003
 0002: Add 'type' field instead of 'balloonable' to PCDIMMDeviceInfo
 0003: chec 'type' instead of 'balloonable'

v3:
    - do not use additional class variable

NVDIMM for now is planned to use as a backing store for DAX filesystem
in the guest and thus this memory is excluded from guest memory
management and LRUs.

In this case libvirt running QEMU along with configured balloon almost
immediately inflates balloon and effectively kill the guest as
qemu counts nvdimm as part of the ram.
