Original GitHub issue: https://github.com/retspen/webvirtmgr/issues/417

Hello. I have logical pool type with underlying LVM volume group:

<pool type='logical'>
<source>
<device path='/dev/md2'/>
<name>svg</name>
<format type='lvm2'/>
</source>
<target>
<path>/dev/svg</path>
<permissions>
<mode>0755</mode>
<owner>-1</owner>
<group>-1</group>
</permissions>
</target>
</pool>

When I change configuration of block device of my VM from

<disk type='block' device='disk'>
<driver name='qemu' type='raw' cache='none' io='native'/>
<source dev='/dev/svg/testlv'/>
<target dev='vda' bus='virtio'/>
</disk>

to

<disk type='volume' device='disk'>
<driver name='qemu' type='raw' cache='none' io='native'/>
<source pool='pool0' volume='testlv'/>
<target dev='vda' bus='virtio'/>
</disk>

I get

OOPS!
Internal Server Error

Are storage pools with volume disk types supported?
