Description Michal Skrivanek 2015-03-12 13:55:33 UTC
this time on RHEL 7 we can increase to the real 4TB...

+++ This bug was initially created as a clone of Bug #1104774 +++

Description of problem:
RHEL 6.5 added support for up to 4,000 GB (NOT 4TB) of memory per VM.  RHEV needs to be updated to reflect this memory max for a VM.

Expected results:
Must be able to configure a VM with a maximum of 4,000 GB

Comment 1 Ilanit Stein 2015-07-07 12:56:18 UTC
Adding qa_ack, based on the following:

Like previous instances in which we've had to "keep up with platform",
RHEV simply needs to validate that the configuration can be applied to
a VM.  Testing of a VM of this size has been performed by the platform
QE team.  Any bugs/issues beyond the ability to configure a VM of this
size will need to be escalated directly to the platform team.

Verified on rhevm

VM can be set to memory size 4096000 MB

Comment 3 Michal Skrivanek 2016-07-21 12:43:14 UTC
12TB? The bug talks about 4

Comment 4 Byron Gravenorst 2016-08-01 23:11:50 UTC
Yes, you are right. I've updated it to reflect the correct amount.
