Again I followed this. In the process I got a low disk space warning (~700MB free). So I found/deleted about 7 old kernel modules from /lib/modules. Now have over 4GB free.
Readers digest version (install from bash_history):
- egrep -c ‘(vmx|svm)’ /proc/cpuinfo
- sudo apt install qemu-kvm qemu-system qemu-utils python3 python3-pip libvirt-clients libvirt-daemon-system bridge-utils virtinst libvirt-daemon virt-manager -y
- sudo systemctl status libvirtd.service
- sudo virsh net-start default
- sudo virsh net-autostart default
- sudo virsh net-list –all
- sudo usermod -aG libvirt $USER
- sudo usermod -aG libvirt-qemu $USER
- sudo usermod -aG kvm $USER
- sudo usermod -aG input $USER
- sudo usermod -aG disk $USER
After install you will have a “Virtual Machine Manager” menu item or CLI “virt-manager”
