Description

This test case will verify that a rawhide guest can be saved and restored.


How to test

  1. Save the rawhide domU using:
    $> virsh save rawhide /var/lib/xen/save/rawhide-save
  2. Wait 20 to 30 seconds, then run 
    $> virsh restore /var/lib/xen/save/rawhide-save
    to restore the guest
  3. After the guest is restored, make sure it has the right memory size, the right number of processors, no softlockups, etc.
  4. Run the previous step with varying memory sizes for the guest, notably around the 4GB boundary.
  5. Copy File:Xen-domu-stress-save-restore.c into the guest, then compile it with 
    $> gcc -O2 Xen-domu-stress-save-restore.c -o Xen-domu-stress-save-restore
  6. Now run the resulting executable inside the guest 
    $> ./xen-domu-stress-save-restore
  7. While the test is running in the guest, run a few save/restore iterations in the dom0:
    $> for i in `seq 1 10` ; do virsh save rawhide /var/lib/xen/save/rawhide-save ; virsh restore /var/lib/xen/save/rawhide-save ; done
  8. Similarly, put the guest under some load - e.g. a kernel compile or program that allocates and modifies large amounts of memory - and run many save/restore iterations.

Expected Results

  1. The save/restores complete successfully with no oops, lockups or error messages.
