I want to use virt-manager to use my VMs, however I want to make sure I am correctly using kvm for native performance.
I ran:
LC_ALL=C lscpu | grep Virtualization
and it outputs:
Virtualization: VT-x
Not too sure if this is supposed to be ok or not? Currently I am noticing Windows 7 to be slow and slightly laggy but I am currently installing the OS and no drivers would be running so just making sure it is working fine?
Do you have opengl acceleration enbaled?
No idea how do I check this?
According to some video he is running this:

See that flag?
Is virtmanager also doing this?
Since qemu is a type 1 hypervisor, does this mean I have to install AMD graphics card drivers on Windows 7 to get native performance?
Well you would go into virt-manager, open your particular virtual machine’s window and click on the ‘Show virtual hardware details’ icon and go to the ‘Display Spice’ tab.
Until your post I didn’t even know you could run windows guests with KVM so I can’t really help you with that as my knowledge is limited.
This is what I see:
I thought with any OS using virt-manager/qemu it would directly use hardware?
Well yeah now you click on opengl and do what it tells you to do.
Again, I know very little about virtualisation; I’ve never run qemu from the command line.
Seem to get this issue now mate.
I watched this video it works:
Even though hardware 3D accelerationg works, it’s still quite laggy.
You’ve probably already done this but it might be a good idea to try to spin up a linux guest to see if the problem is with windows specifically, or your configuration.
