Virtual box 6.1 is unusable on windows 10

Post by st9x »

Was running virtual box 5.xxxx for the last year on a windows 10 host running mostly Ubuntu 16.xx and 18.xx guests
Recently upgraded to 6.1 and it is unusable! Any GUI interface is slow and unresponsive. Login times > 15 minutes. Tried all the combinations for display with 3d acceleration enabled/disabled. Searched the forums for solutions and nothing has worked. Baffled how a software upgrade can make things even worse!

A log file would have helped. Failing that it sounds like your Windows 10 problems are going to be caused by have Hyper-v enabled and VT-x not enabled.
