I really love my HP Z820 Workstation. Two Xeon CPUs, 256GB of RAM. Runs VMWare. The fans scream like a banshee when it is powered up.
However, when the power goes out (happens three+ times a year), it has the habit of “forgetting” that VT-X and VT-d are enabled. So, I have to go into the BIOS, and find the setting to turn it back on again.
Just documenting (because “Security” is never where I expect to find this setting):
