[ovirt-users] Cannot create VM with custom memory amount

[Ondra Machacek]

You must make sure you have `memory` attribute higher then `memory_guaranteed`

For example this will work:

 memory=2*2**30,
 memory_policy=types.MemoryPolicy(
     guaranteed=1*2**30,
 ),

and this won't work:

  memory=1*2**30,
  memory_policy=types.MemoryPolicy(
      guaranteed=2*2**30,
  ),

Because guaranteed memory must be higher.
