Subject: [PATCH 1/2] migration: increase max-bandwidth to 128 MiB/s (1 Gib/s)
|

O-Subject: [RHEL-AV-8.3.0 qemu-kvm PATCH] migration: increase max-bandwidth to 128 MiB/s (1 Gib/s)
|

Bugzilla: 1874004

||||
RH-Acked-by: Daniel P. Berrange <berrange@redhat.com>

||||
RH-Acked-by: Greg Kurz <gkurz@redhat.com>
|
||||
|
||||
max-bandwidth is set by default to 32 MiB/s (256 Mib/s)
|
||||
since 2008 (5bb7910af031c).
|
||||
|
||||
Most of the CPUs can dirty memory faster than that now,
|
||||
and this is clearly a problem with POWER where the page
|
||||
size is 64 kiB and not 4 KiB.
