Hi, 
The package virtualbox-websrv does not contain a firewalld service defination. 
This makes is very hard to allow traffic through the firewall using YaST. 

Using the following commands created the defination. 

```
firewall-cmd --permanent --new-service=vboxweb
firewall-cmd --permanent --service=vboxweb --set-description="service to
remotly manage VirtualBox"
firewall-cmd --permanent --add-port=18083/tcp --zone=internal --service=vboxweb
firewall-cmd --permanent --set-short="vboxweb" --service=vboxweb
```

This created the file 

```
cat /etc/firewalld/services/vboxweb.xml
<?xml version="1.0" encoding="utf-8"?>
<service>
  <short>vboxweb</short>
  <description>service to remotly manage VirtualBox</description>
  <port port="18083" protocol="tcp"/>
</service>

```

I can't figure out how to submit this to the packaging system as an issue, so i
thought I should log it here.
