In Red Hat Enterprise Virtualization 3, why does the GUI show 'Shared Memory' as 0%, even though it appears to be in use?

Solution Verified - Updated -

Issue

  • A hypervisor is in a cluster with memory page sharing enabled.
  • Appears to be running above its memory size, and it shows memory page sharing as "Active".
  • The hypervisor reports /sys/kernel/mm/ksm/pages_sharing e.g. 560128, but 'Shared memory' is showing 0%

Environment

  • Red Hat Enterprise Virtualization 3.0
