Описание

This test case checks that basic live migration using libvirt between two Fedora 12 hosts works correctly. NOTE: this testcase explicitly requires both the source and destination machines to have more than 4GB of memory to safely execute. Since KVM does support swapping, you may be able to get away with less memory in the machine, but your performance will probably suffer.


Как проводить тестирование

  1. On the source machine, edit the guest so that it has exactly 4096MB of memory.
  2. On the source machine, start the guest.
  3. Once the guest has fully booted, find out the IP address of the guest (by logging into the guest and running ifconfig, or whatever is equivalent in the guest OS of your choice). From the source machine, start a ping to the guest:

    $ ping <guest-IP>

  4. Now on the source machine execute:

    $ virsh migrate --live <guestname> qemu+ssh://<destination host>/system

  5. Shutdown the guest on the destination machine. Once it's successfully shut down, edit the guest on the source machine and give it random, differing amounts of memory: 4097MB, 8192MB, etc. Then repeat the test for these differing amounts of memory.
  6. Repeat the entire test for as many different guest OS's as are relevant. We would at least like to see the following guests:
    1. Fedora 12
    2. Fedora 11
    3. RHEL-4
    4. RHEL-5
    5. Windows XP
    6. Windows Vista
    7. SUSE

Ожидаемые результаты

  1. After executing the virsh migrate command, the guest should migrate over to the destination machine, and not be running anymore on the source machine. Use $ virsh list on both machines to verify this. Additionally, the ping that was started in step 3 should continue uninterrupted.
