I did a fresh install of solus 4.0 and installed virtual machine manager from the Software Center. After starting and enabling libvirtd, it still gave me the following error" The host does not support virtualization" or something similar when I tried to create a new VM.
Tried to run QEMU directly on the terminal -the following 2 libraries needed to be installed for QEMU to run:
Spice
virglrender
QEMU & Virtual Machine Manager ran fine after the installation of those libraries. The packaging needed to be fixed.
