Some of the Linux VMs services authenticated with the Windows domain.  I wanted to set up at least one non-x86&amp;#x2F;x64 emulated-CPU VM but never got that working very well in QEMU.&lt;p&gt;The exercise was a good (and incremental) learning experience and increased my general networking and sys-admin knowledge, which I&amp;#x27;ve used well as part of my software engineering career.  I would have been lost in many professional situations without it.  QEMU&amp;#x2F;KVM are awesome.&lt;p&gt;EDIT:  more and better words</text></comment>

IIRC Redhat distributes signed drivers for Windows for free.&lt;p&gt;The problems I did have were with VMs I tried to convert from VMware to KVM, and those stemmed from Windows&amp;#x27; inability (version 7) to properly handle changing hardware. Perhaps it&amp;#x27;s better at nowadays.</text></comment>
