Which kind of application u want to do? If u throw out multi questions at once, we may hard to catch,
Run a ubuntu in vmware cannot get correct real-time performance,
And a normal PC mainboard's BIOS usually cannot match real-time profile also.
we can recommend some Industry PC module available on market if u want to test,
