Subject: [ovirt-users] Cannot run VM. Memory size exceeds supported limit	for given cluster version.

Hi, 

I am running Ovirt 3.5.1 and have the following settings in the engine config for VM memory :- 

----------------- 
[root at ccr01 ~]# engine-config -g VM32BitMaxMemorySizeInMB 
VM32BitMaxMemorySizeInMB: 65536 version: general 

[root at ccr01 ~]# engine-config -g VM64BitMaxMemorySizeInMB 
VM64BitMaxMemorySizeInMB: 524288 version: 3.0 
VM64BitMaxMemorySizeInMB: 2097152 version: 3.1 
VM64BitMaxMemorySizeInMB: 2097152 version: 3.2 
VM64BitMaxMemorySizeInMB: 4096000 version: 3.4 
VM64BitMaxMemorySizeInMB: 4096000 version: 3.5 
VM64BitMaxMemorySizeInMB: 2097152 version: 3.3 
[root at ccr01 ~]# 
-------------------- 

When i create a guest VM more than 64GB memory,VM is failed to start with following error: 

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

Steps to Reproduce: 
1. Create new VM or edit existing VM Memory Size to "65536 MB" from Ovirt GUI. 
2. Created the guest VM through template 64-bit... so it will support more than 16 GB memory. 
3. Now, Start the VM. 

Thanks, 
Punit
