How to cap cores for all VMs in OVM platform?

User_Y2Y3I

Hi,

As for the Oracle licensing requirement, we have been making below restrictions on CPU/core capping on our ldom environment. For example below is from Solaris cdom

[email protected]:~# ldm list -o resmgmt,core oedby-ttzm3

NAME

oedby-ttzm3

CORE

  CID  CPUSET

  10   (80, 81, 82, 83, 84, 85, 86, 87)

  11   (88, 89, 90, 91, 92, 93, 94, 95)

CONSTRAINT

  cpu=whole-core

  max-cores=2

  threading=max-throughput

[email protected]:~# ldm list -o resmgmt,core oedby-orazm1

NAME

oedby-orazm1

CORE

  CID  CPUSET

  5   (40, 41, 42, 43, 44, 45, 46, 47)

  6   (48, 49, 50, 51, 52, 53, 54, 55)

CONSTRAINT

  cpu=whole-core

  max-cores=2

  threading=max-throughput

We would want to have have similar config on OVM environment also, assuming that OVM is also based on ldom technology. Is there any way or command to check and make similar restriction for all the VM's we will make on this OVM?

VM Servers are Oracle VM, so I can't see ldm commands like we see them in Solaris.

Please suggest

Thanks

Hi,

Please review this document.

Hard Partitioning with Oracle VM Server for x86

Oracle VM provides Hard Partitioning, which is supported as per Oracle Licensing Policies.

Also, if you are doing the fresh implementation consider using OKVM. Oracle VM does not have long-term support from Oracle.
