Strange behavior for the CPU topology calculation in case of the error

[hstastna]

Description of problem:
There's an issue in the CPU Topology Options in the Basic Settings of the Create VM Wizard:
"The current scenario is that the user can choose all kinds of combinations while the values are dynamically changed when selecting different values in different order without any logic. If values are invalid then it failed on backend or it is turned to 1, 1, 1 or other invalid non chosen values with the error displayed but without letting the user remember what he tried to set. For example- the user set values to 1, 1, 384 but error appears for 16,1,8."

Steps to Reproduce:

Possible solutions:

1. Display a fixed (empty) or the original invalid value in case of the error occurrence, instead of switching to a different invalid values that the user didn't select.
2. Another possibility is to remove the whole "auto calculation" for CPU topology and to let the VM created with the original user selection. If wrong then it will fail on backend with the correct error. If this solution would be implemented, then this issue won't be relevant anymore and could be closed.
