Fixed In Version:	org.ovirt.engine-root-3.5.3-2	Doc Type:	Bug Fix
Doc Text:	Previously, if you created a virtual machine and selected 'Other OS' for the Operating System field, the operation system type defaulted to 32 bit. As a result, when installing a 64 bit operating system not present in the list of operation systems, the virtual machine can only use up to 20 GB of RAM, which is the limit for 32 bit operation systems. With this update, the "Other OS" option now defaults to 64 bit. Any operating system installed in the virtual machine is allowed to use up to 4TB of memory if it is capable for it. 32 bit operating systems are still limited to 20 GB of RAM.	Story Points:	---

Comment 2 sefi litmanovich 2015-05-18 15:27:45 UTC

verified with rhevm-3.5.3-0.2.el6ev.noarch.

steps:
1. set engine-config -s VM32BitMaxMemorySizeInMB=512
2. set engine-config -s VM64BitMaxMemorySizeInMB=1024 --cvers=3.5
3. restart engine.
4. created a rhel-7.1 vm with 64bit architecture, set os to 'Other OS'.
5. set vm memory to 512MB.
6. start vm - vm started successfully.
7. set vm memory to 1024MB.
8. start vm - vm started successfully.
9. set vm memory to 2048MB.
10. start vm - get the expected message:

Cannot run VM. Memory size exceeds supported limit for given cluster version.
