I already installed qubes it's booting to gui but i can't start any domain i keep getting this error. i have amd 5600x with amd-v enabled. i think it got something to do with csm being enabled which i believe will disable some virtualization feature but if i disable csm i can't boot into qube or reinstall the os
this happens in second phase of installtion (after first reboot configuration) 
sudo cat /var/log/libvirt/libxl/libxl-driver.log 
You mention that you have CPU Virtualization enabled, amd-v. What you don't say is if you have IOMMU support enabled. And from this AMD processor guide, I don't think the 5600x has IOMMU support. I don't see it in the feature list.
Qubes-OS is heavy on the virtualization requirements.
You can test whether this is the case by converting sys-usb and sys-net to Para Virtualization (PV). Then see if sys-net comes up and if you are able to launch other VMs.
From:
https://www.qubes-os.org/doc/installation-troubleshooting/
You can change the virtualization mode by bringing the Qubes Manager from Qubes Tools. Right click on the sys-net VM. Chose Settings, then the Advanced tab, then in the dialog there is Virtualization, change it from HVM to PV.
If you are using a non-UEFI BIOS, your grub2 mkconfig command line will be "sudo grub2-mkconfig -o /boot/grub2/grub.cfg".
