When turned on, this will disable the version-checking of hypervisors during live-migration. This can be useful for operators in certain scenarios when upgrading. E.g. if you want to relocate all instances off a compute node due to an emergency hardware issue, and you only have another old compute node ready at the time. Note, though: libvirt will do its own internal compatibility checks, and might still reject live migration if the destination is incompatible.

feature:

|
|
Adds a workaround that allows one to disable hypervisor
|
|
version-check on live migration. This workaround option can be
|
|
useful in certain scenarios when upgrading. E.g. if you want to
|
|
relocate all instances off a compute node due to an emergency
|
|
hardware issue, and you only have another old compute node ready at
|
|
the time.
|
|
|
|
To enable this, use the config attribute
|
|
``[workarounds]skip_hypervisor_version_check_on_lm=True`` in
|
|
``nova.conf``. The option defaults to ``False``.
