Add nova file_backed_memory and memory_backing_dir support for qemu.conf
|
|
|
|
The libvirt driver now allows utilizing file backed memory for qemu/KVM
|
|
virtual machines, via a new configuration attribute
|
|
``[libvirt]/file_backed_memory``, defaulting to 0 (disabled).
|
|
|
|
``[libvirt]/file_backed_memory`` specifies the available capacity in MiB
|
|
for file backed memory, at the directory configured for
|
|
``memory_backing_dir`` in libvirt's ``qemu.conf``. When enabled, the
|
|
libvirt driver will report the configured value for the total memory
|
|
capacity of the node, and will report used memory as the sum of all
|
|
configured guest memory.
|
|
|
|
Running Nova with file_backed_memory requires libvirt version 4.0.0 and
|
|
qemu version 2.6.0
