Look for these lines in the guest vbox.log:
{timestamp} HM: HMR3Init: Attempting fall back to NEM: VT-x is not available
{timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...
VT-x may be called AMD-V in the log, for AMD hosts.
If these lines are present, Hyper-V is enabled. See I have a 64bit host, but can't install 64bit guests posts 2 & 3, and HMR3Init: Attempting fall back to NEM (Hyper-V is active).)

Hello Guys,
pretty new here but been using virtualbox with almost no issues.
been trying to the install centos 8 for the past week but i get CD Check Failed every single time.
I've downloaded from 15 different mirrors and i've tried the stream and live dvd.
I've then tried installing centos 7 and 6 using minimalist, live dvd from at least 10 different mirrors and every install failed.
i've tried so many different solution of reinstalling virtualbox over and over and over again and still same.
i'm at wits end to try and figure this out and would appreciate some help.
