then service libvirtd restart
adduser <youruser> libvirt
adduser -aG <youruser> libvirt
To create the vm run the command
```
ansible-playbook main.yml
```
## Troubleshooting
```
net.ipv4.ip_forward = 1 ?
```
```
modprobe kvm_intel
```
If running in `/root` may need to edit config
```
# edit /etc/libvirt/qemu.conf
user = "root"
group = "root"
$ service restart libvirtd
