I enable virtualization in my bios. And can click add VM, but after doing that the create button does nothing. 

Need more info... Diagnostics file for the system possibly?  Also, enabling virtualization is not enough, With Intel you probably enabled VT-x technology or on AMD, you probably enabled AMD-V technology... But you also need to enable for Intel VT-d or AMD VT-d... This enables hardware passthrough and fixes some other issues... I belive KVM/Qemu requires this to be enabled...  Your BIOS may label this several different things, but it usually will be separate from the basic "Enable Virtualization"

I found out what the problem was. Inside settings/vm Manger I which the default iso file location from mnt/user/iso to my media folder mnt/user/media/james/iso

Same with the domain folder 

 

I can still post the diagnostic file if you want it 

Hello,

I am getting the same problem, diagnostics attached if someone could take a look.

Thx
