Subject: [Qemu-devel] [PATCH 0/2] migration: Dynamic cpu throttling for auto-converge
Date: Mon, 1 Jun 2015 11:17:29 -0400 [thread overview]
Message-ID: <1433171851-18507-1-git-send-email-jjherne@linux.vnet.ibm.com> (raw)
This patch set provides a new method for throttling a vcpu and makes use of said
method to dynamically increase cpu throttling during an autoconverge
migration until the migration completes. This method ensures that all migrations
will eventually converge.
The method used here for throttling vcpus is likely not the best. However, I
believe that it is preferable to what is used for autoconverge today.
This work is related to the following discussion:
