The virtualization server host computer system comprises a virtual physical server (100), a thin client A and a thin client B. The virtual physical server (100) is provided with a first virtual machine (110) and a second virtual machine (120). After an operating system and an applicationprogram in an industrial control computer (210) of an engineer station and an industrial control computer (220) of an operator station are packaged, the converted virtual machine files are seamlesslymigrated into the first virtual machine (110) and the second virtual machine (120) respectively, and run in the virtual machines; the first virtual machine (110) and the second virtual machine (120)are remotely accessed through the thin client A and the thin client B to realize the operation of the original host computer program. The virtualization server host computer system and the related upgrade technology of the invention are ingenious in design and strong in practicability.
