GitHub user marcaurele opened a pull request:

    CLOUDSTACK-7982 - KVM live migration

    This is the forward port of our KVM live migration implementation in 4.4.2 to the master
    Feedback is welcome. I still have to write the documentation to explain some configuration
for libvirt and some config value in CS.
    Things left:
    - [ ] Write documentation in cloustack-docs-install & open PR with a link to this
    - [ ] Add to the upgrade SQL file:
    UPDATE  `cloud`.`hypervisor_capabilities`
    SET  `storage_motion_supported` =  1
    WHERE  `hypervisor_capabilities`.`hypervisor_type` =  'KVM';
    - [ ] Update the PR with a final description

    live migration: cancel migration job on timeout exception
    Currently if a migration job takes longer than the max time for a CS job,
    then the disk at the remote is deleted but the job keeps running. This
    leads to a situation were the VM could be moved on the destination
    hypervisors but without a visible disk on the filesystem.
    This fix attempt to cancel the migration job on the source host before
    requesting the disk removal at the destination.

    Live migration fixes (#20)
    Multiple bugs fixes:
    * Incorrect disk size: when provisioning the volume at the destination,
      the size was taken from the template and not from the original volume
    * Incorrect details when returning an error: now if an exception is
      raised by Libvirt at the agent level, the error message is forwarded
      correctly all the way into the job response text.
    * Incorrect volume state: when a migration failed, the volume state was
      inconsistent and stayed in "Migrating", those interfering with future
      commands on the VM. As a result, the event message wasn't sent
