vhost: claim support of guest announce
|
||
|
|
|
||
|
|
It's actually a feature already enabled in Linux kernel (since v3.5).
|
||
|
|
What we need to do is simply to claim that we support such feature,
|
||
|
|
and nothing else.
|
||
|
|
|
||
|
|
With that, the guest will send an ARP message after live migration
|
||
|
|
to notify the switches about the new location of migrated VM.
