Based on my understanding, machine guests such as linux on z/VM can get cpu
resource by their SHARE value.
For example, LINUXA system has SHARE RELATIVE 100. LINUXB system also has
SHARE RELATIVE 100. So LINUXA and LINUXB both has 50% of real physical
processor resource.
If LINUXA has 2 virtual processors defined in DIRECTORY, and LINUXB has
only 1 virtual processor. What difference between LINUXA and LINUXB?

Question1: my understanding is following, is it correct?
LINUXA and LINUXB both has 50% of real cpu resource. Because LINUXA has 2
virtual processors, every virtual processor of it has 25% of real cpu
resource.

Question2: As far as cpu resource is concerned, what difference between
LINUXA and LINUXB?

Question3: usually what factor determines defining multiple virtual
processor for linux guest? Application determines?
