@wido Thanks for working on this, awesome!
I was testing this PR and found that the SSVM and CPVM systemvms do not
start properly. This is the error:
```

Here is the channel dir:
```
[root@kvm1 channel]# ls -al /var/lib/libvirt/qemu/channel/
total 12
drwxr-x---. 3 qemu qemu 4096 Oct 28 09:55 .
drwxr-x---. 7 root root 4096 Oct 28 12:39 ..
drwxr-x---. 2 qemu qemu 4096 Sep 15 14:03 target
```
The `target` folder was empty.
I've installed the rpm package that I've built from this branch. The agent
seems to run as root:
```
root 9815 0.4 3.1 4815960 255916 ? Sl 10:17 0:41
/usr/lib/jvm/jre/bin/java -Xms256m -Xmx2048 <cut>
```
It was tested on a KVM hypervisor on CentOS 7. Ping me if you need more
details.
