Description of problem:
virt-filesystems outputs a non-existing device:

# virt-filesystems --partitions --long -a /usr/kvm/keys.qcow 
Name       Type       MBR  Size        Parent
/dev/sda1  partition  83   254803968   /dev/sda
/dev/sda2  partition  05   1024        /dev/sda
/dev/sda5  partition  8e   1889533952  /dev/sda

Notice above it outputs /dev/sda5

However when I try to resize it, virt-resize says that /dev/sda5 does not exist. It finds only these two partitions:

2 partitions found
/dev/sda1:
        [..]
/dev/sda2:
        [..]

Here is the full output when trying to resize:

# virt-resize -d --expand /dev/sda5 --LV-expand /dev/keys/var /usr/kvm/keys.qcow /var/keysnew.qcow2

virt-resize: error: /dev/sda5: partition not found in the source disk 
image (this error came from '--expand' option on the command line).  
Try running this command: virt-filesystems --partitions --long -a 
/usr/kvm/keys.qcow

If reporting bugs, run virt-resize with the '-d' option and include the 
complete output.
