upgrade:
|
||
|
- |
|
||
|
On AArch64 architecture ``cpu_mode`` for libvirt is set to ``host-passthrough``
|
||
|
by default.
|
||
|
|
||
|
AArch64 currently lacks ``host-model`` support because neither libvirt nor
|
||
|
QEMU are able to tell what the host CPU model exactly is and there is no
|
||
|
CPU description code for ARM(64) at this point.
|
||
|
|
||
|
.. warning:: ``host-passthrough`` mode will completely break live
|
||
|
migration, *unless* all the Compute nodes (running libvirtd) have
|
||
|
*identical* CPUs.
