virtualbox.org

Hi, I installed cloudera (centOS) one week ago and it works perfectly. After instalIing other programs, mi virtualPC does not work anymore. I tryed uninstall and install again cloudera, also uninstall the other programs, but does not work. I tried to install ubuntu in other virtualPC but does not work. What can I do? I think the program that broke it was docker, i descativate Hyper-v but i was not lucky. Please HELP!
Thanks!

I can not upload logs because there are too big, i give the last part of them.

Hardening log exit code is 0, so no hardening problems.

Regrettably the last part of the vbox.log misses all the good stuff.

Please right-click the guest in the main Virtualbox window's guest list, choose Show Log.

Search the far left tab's log for this text:

Attempting fall back to NEM

If you find it, Hyper-V is enabled. If you are still running 6.1.14 or earlier, update to 6.1.16, and try again.

If the 6.1.16 log still shows these words, Hyper-V needs to be disabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

If you don't find that text, save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.
