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

[TranceWorldLogic .]

Thanks for your help Ondra,

Now I able to allocate 300MB memory for VM.

But I observe some different behaviour than mention in your mail, let me
explain.

Let consider, parameter memory value is M.
And parameter for guaranteed memory value is G

Case 1> M < G => Fail to create VM got same error.
Case 2> M = G => VM created successfully.
Case 3> M > G => VM created successfully.

On GUI, in general tab it show guaranteed memory as "Physical Memory
Guaranteed"  and memory parameter is shown as "Defined Memory".
Meaning of those two parameter look to me,
1> guaranteed value mean like as minimum requirement to run VM and
2> memory value is like if available would be better.

Would you please provide input on same ?


Thanks,
~Rohit
