Tuning the timeout, downtime and speed cap values for RHEV 3.x live migration
Issue
- In RHEV, is there a timeout for live migration of a guest from one host to another one? If I start live migration of a vm with 128 GB of memory, will it hit a timeout and abort live migration?
- Is the network bandwidth for live migration capped?
- Is there a limit on concurrent live migrations?
- How to limit IP bandwidth used by migrate actions
- I have read somewhere in the RHEV 3.0 documentation that there is the ability to constrain a) number of concurrent migrations; and b) amount of IP bandwidth used per migration. I however cannot find what the default setting is nor where it is set / how to set it.
- What is migration downtime and how to change it?
Environment
- Red Hat Enterprise Virtualization (RHEV) 3.x.
