This test case will verify that a F-11 guest can be saved and restored.

How to test

  1. To save and restore the guest, run:
  $> virsh save f11 /var/lib/xen/save/f11-save
  $> sleep 20
  $> virsh restore /var/lib/xen/save/f11-save
  1. After the guest is restored, make sure it has the right memory size, the right number of processors, no softlockups, etc.
  2. Run the previous step with varying memory sizes for the guest, notably around the 4GB boundary.
  3. Copy File:Xen-domu-stress-save-restore.c into the guest, compile and run with:
$> gcc -O2 xen-domu-stress-save-restore.c -o xen-domu-stress-save-restore
$> ./xen-domu-stress-save-restore
  1. 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 f11 /var/lib/xen/save/f11-save ; virsh restore /var/lib/xen/save/f11-save ; done
  1. 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.
