VMware virtual machine installed ubuntu appear stuck unresponsive

In fact, I have been more exclusive use Linux, but it does have a lot of places, previously used centOS, today installed Ubuntu system inside a virtual machine in VMware, a direct result of a black screen, nothing, disk checking process found no CPU IO, virtual machines around 20%, and then created a new, still the same, and can not shut off, the last restart of the physical machine, the virtual machine and then delete the file you just created.
New again, we found a virtual machine hardware inside a printer, next to the prompt to enable in the preferences. I do not need to use in the virtual machine printer, then delete the printer directly to this project, another project in the CPU inside checked all of the virtualization options, boot to normal. Then I preferences which enabled printer, and a new virtual machine, do not delete the printer hardware, and then also boot normally.
Above for reference only, do not know is not the reason, I may restart after the physical machine has no problem. Relatively late, and I do not want to reproduce the failure, have encountered can try.
