Why do Multiple VMs Migrations sometimes terminate prematurely? Are there any tunables to avoid this?

Solution In Progress - Updated -


  • Why sometimes our Multiple VMs Migration were terminated prematurely?
  • Is there any tunable to avoid this?

We're using 16 nodes RHEV hypervisor. One day, something happened on a hypervisor and live migration started automatically.
However, the migration process was stopped before migrate all guests.

Q1: What is the root cause of this?
Q2: Is there any tunable parameter to avoid this?


  • Red Hat Enterprise Virtualization 3.2
    • It may also happen with Red Hat Enterprise Virtualization 3.0 or later.
      Please also see the "Root Cause" section.
