##### SUMMARY
<!-- Explain the problem/feature briefly -->
We found a Bug into the PR #3819. Sometimes hypervisor (Linux, KVM) detect the partitions on the attached disk. This leads to additional paths. Since we only check the path of the disk in the XML of the virtual machine and compare them with the "/dev/disk/by-path" we find additional paths.
```
lrwxrwxrwx. 1 root root 10 Jul 17 16:52 /dev/disk/by-path/ip-10.24.50.230:3260-iscsi-iqn.2010-01.com.solidfire:nhjj.root-1540.1750-lun-0 -> ../../sddm
lrwxrwxrwx. 1 root root 11 Jul 17 16:52 /dev/disk/by-path/ip-10.24.50.230:3260-iscsi-iqn.2010-01.com.solidfire:nhjj.root-1540.1750-lun-0-part1 -> ../../sddn1
```
```
<disk type='block' device='disk'>
<driver name='qemu' type='raw' cache='none'/>
<source dev='/dev/disk/by-path/ip-10.24.50.230:3260-iscsi-iqn.2010-01.com.solidfire:nhjj.root-1540.1750-lun-0'/>
<backingStore/>
<target dev='vda' bus='virtio'/>
<serial>154b1f1d2c5d476cae31</serial>
<alias name='virtio-disk0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>
</disk>
```
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.
-->
<!-- Paste example playbooks or commands between quotes below -->
~~~
1. use a managed storage like Solidfire
2. use "partprobe" to make partitions visible, look into "/dev/disk/by-path" -> "-lun-0-part1"
3. start a virtual machine, or try to start them
4. wait for the cleanup job which kill the disk of the virtual machine
~~~
<!-- You can also paste gist.github.com links for larger files -->
##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
dont look for other paths than the correct one in the XML, dont logout other paths
~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
~~~
logging out the disk from virtual machines they are running
