[OpenIndiana-discuss] Virtual Box can not start Windows 7

[Apostolos Syropoulos]

Hello,
I have an old Windows 7 image that I used on my old system and 
now that I am trying to use it on my new system I get:
AMD-V setup failed: VERR_SVM_IN_USE (VERR_SVM_IN_USE).
VirtualBox can't enable the AMD-V extension. Please close all other virtualization programs. (VERR_SVM_IN_USE).
Result Code:
NS_ERROR_FAILURE (0x80004005)
Component:
ConsoleWrap
Interface:
IConsole {6ac83d89-6ee7-4e33-8ae6-b257b2e81be8}
And dmesg shows a line like the following each time I try to start the VM:
Mar 10 22:30:48 adalind vboxdrv: [ID 702911 kern.notice] vboxdrv: XXXXXXXXXXXXXXXX VMMR0.r0

I have already enabled the SVM Mode from the Gigabyte BIOS 
(my system has an AMD Ryzen 7 5700X 8-Core Processor × 16 processor). 

Can someone suggest a way to make the VM usable again?
Regards,Apostolos
