This the patch file: (See attached file: libvirt_migration_ns_100503.patch)
ACK, patch looks fine now.
No objections to the patch that was committed, but FYI there is an improvement that can be done to it.
If you run 'virsh domjobinfo $GUEST' while migration is running it tells you the progress of migration. It gives overall progress, and memory progress. The APi was designed to allow us to report storage progress too. To wire this up look at the method
qemuDomainWaitForMigrationComplete
where it updates the priv->jobInfo variables. You'll also need to add extra params to the qemuMonitorGetMigrationStatus() method to return the disk processed/remaining/total stats
virsh should already be able to report this data once the QEMU driver is wired up

Thank you. I will look into implementing the improvement when I have time. However, it won't be for a while since I have some pressing deadlines that I have to meet in the next few months. regards, Kenneth Nagin Ph: +972-4-8296227 Cell: 054-6976227 Fx: +972-4- 8296113 http://researcher.watson.ibm.com/researcher/view.php?person=il-NAGIN http://www.reservoir-fp7.eu/
