What it says. You need to enable AMD-v in your host PC BIOS.

Today it looks very funny to me, all VMs unable to start. They have been running on this PC for more than 2 years. I haven't done anything on PC BIOS

I found following URL
Virtualization (VT-x/AMD-V) - Enabling virtualization on your computer for running 2N® Access Commander
https://2nwiki.2n.cz/pages/viewpage.act ... d=75202968

Code: Select all

Asus

Most commonly: F2.

Alternatively: Delete or Insert key, and less commonly F10.
Turn ON the System.
Press F2 key at startup BIOS Setup.
Press the right arrow key to Advanced tab, Select Virtualization Technology and then press the Enter key.
Select Enabled and press the Enter key.
Press the F10 key and select Yes and press the Enter key to save changes and Reboot into Windows.
.....

But on PC BIOS I couldn't find "Virtualization Technology" on Advanced menu. Neither I can find AMD-V on searching.

Please help. Thanks

Edit

I found following warning at the bottom of "Virtual Machine Manager"

Code: Select all

Invalid settings detected

System: Acceleration page:
The hardware virtualization in enabled on the Acceleration setion of the System Page although it is not supported by the host system.  It should be disabled in order to start the virtual system

System -> Acceleration
Paravitualization Interface: Default
Hardware Virtualzation: [v] Enable Nested Paging
[Cancel] [Ok] (grey-out)

I can uncheck "Enable Nested Paging" but I can't click [OK] which is always grey-out

The FAQ I directed you to said nothing about nested paging, so I don't know why you want to discuss that.

Also, your original post did not say that the VMs were previously working on this host. If that is true then something has changed, and you have not provided enough information to say what. Either the BIOS setting has been reset, or you upgraded VirtualBox from v5 and was relying on a feature (software virtualization) which has been discarded in v6, or you have another VM platform running.

Sorry, I just found that warning after posting my original post.

I just found all VMs unable to start. Besides I use the VMs for testing only not for daily working. Neither I have made any change on BIOS

or you upgraded VirtualBox from v5 and was relying on a feature (software virtualization) which has been discarded in v6,

I have upgraded to V6.1 about one week ago. But no problem was found after upgrade.

or you have another VM platform running.

Sorry I don't follow. I have only one VM VirtualBox Manager running. However I have several new groups created because I have about 30 VMs installed but not running at the same time. Please see attached photo.

I'll supply more information upon receipt of your request. Thanks

I have upgraded to V6.1 about one week ago.

6.1.x now requires VT-x/AMD-V/SVM to be enabled for all guests. 6.0.x & earlier don't require this setting.

But on PC BIOS I couldn't find "Virtualization Technology" on Advanced menu.

You'll have to find it or go back to 6.0.x. AMD also calls it SVM. Get your motherboard's manual, it should show how to enable the setting.

Yes, your're right. It is named SVM.

On BIOS after having SVM enabled VMs are now working.

Lot of thanks for your help.

Great! Glad you're up and running.
