Hi, I am trying to write the patch file for live migration which uses UDP as the transport protocol.
---So I prepare to edit the existing API which uses the TCP as the transport protocol for the migration.I want to know the modules executing during live migration in current libvirt.(I m using ubuntu10.10 as the guest and suitable latest version of libvirt)
----If any document which clearly shows the actual migration process. I mean which are the functions called during live migration and how the data flow occurs between the two physical machines or the hypervisor.
--In LAN the UDP can be used for the live migration as the loss of packets and collision of packets are negligibly less.
--Even RUDP can also be used instead of TCP, as RUDP is reliable.
--The complete set of the code which responsible for live migration is required where I can get that..?
You've already asked these questions before and got two sets of answers: http://www.redhat.com/archives/libvir-list/2011-May/msg01641.html http://www.redhat.com/archives/libvirt-users/2011-May/msg00076.html To repeat again: the migration transport is in QEMU, so send these questions to the QEMU mailing list.
