Virtual Machines: Do you have one ? Xen,VMware, Virtual Box

AI Thread Summary
Virtual machines (VMs) are widely utilized for various purposes, including gaming, software testing, and server consolidation. Users report employing tools like VirtualPC to run legacy software, such as old MSDOS games, although limitations like lack of USB controller support and slower performance compared to native systems are noted. Alternatives like DOSBOX and GliDos are also mentioned for gaming. In professional settings, VMs facilitate the management of incompatible software configurations, allowing users to switch between setups without data loss. Many professionals, including network engineers, run multiple instances for network configurations, while IT consultants often create separate environments for different client projects to prevent cross-contamination. The trend towards virtualization is evident in data centers, where server consolidation is increasing density and efficiency. Overall, virtualization serves diverse needs across both personal and professional domains.

I use VirtualPC to run old MSDOS games under Windows XP. One shortcoming is that there is no support for USB gaming controllers. It's also slower than native mode, but the old games ran on much slower system, so that's not an issue. Other alternatives for gaming are DOSBOX and GliDos.
 


So you are running MSDOS as a virtual instance ? ... : ] ...

Cool ...
 


The last time I used anything virtualization was to set up a sandbox for broken software. We had some process control software that needed to have different incompatible configurations for different situations for one user. Switching between the two configurations took reinstallation and some extra steps. Any misstep and it ate our data. It was easier to just have another copy of Windows running in VirtualBox with the second configuration ready to go.
 


I use virtualization every day with VMWare Workstation. I can't live without it.

Both my Mac and PC have linux instances running. I generally have both a server and and a workstation instance running. This is mainly for cross-platform compilation and deployment testing.

My brother is a network engineer and he has 10+ instances running of virtual network configurations.

Tons of companies are consolidating their servers using virtualization. Data centers are getting extremely dense these days.

Also, a common thing IT consultants do to keep projects from different clients from 'contaminating' each other is to give each client their own sandbox.

Thread 'Windows 10 Now Not Supported'

Well, the date has now passed, and Windows 10 is no longer supported. Hopefully, the readers of this forum have done one of the many ways this issue can be handled. If not, do a YouTube search and a smorgasbord of solutions will be returned. What I want to mention is that I chose to use a debloated Windows from a debloater. There are many available options, e.g., Chris Titus Utilities (I used a product called Velotic, which also features AI to prevent your computer from overheating etc...
