Description Andrew Dahms 2015-08-20 02:31:21 UTC
In RHEV 3.6, it is now possible to hot-plug memory into virtual machines. The unplug process is being handled as a separate issue, but a table similar to that for hot plugging CPUs should be created to cover this new feature and provide an overview of what it does.

Comment 1 Andrew Dahms 2015-08-24 04:58:47 UTC
Assigning to Tahlia for review.

Tahlia - the bug description calls for an article, but given that this is memory rather than a CPU, perhaps just a quick note in the Admin Guide is required.

Let me know what you think.

Comment 2 Tahlia Richardson 2015-09-03 06:34:22 UTC
I'm hoping for just a quick note in the Admin Guide, but it will probably also require an update to the REST API Guide.

Comment 11 Israel Pinto 2015-11-11 09:40:59 UTC
Things that are missing in VMM and Users guide is:
1. The hotplug is possibly in multiplication of 256M
2. The max memory devices to VM is 16, after reboot the counter it back to 1.
3. Check in VM devices tab that the new memory device is add to VM.

Comment 13 Israel Pinto 2015-11-18 06:42:51 UTC
I verify the additional info, looks good

Comment 14 Tahlia Richardson 2015-11-20 04:30:46 UTC
This content as verified in comment 10 is in the 3.6 Beta documentation at
https://access.redhat.com/documentation/en/red-hat-enterprise-virtualization/

Further updates will be in the next asynchronous release.
