[libvirt-users] Resizing lvm fails with fedora20

Hi,
I'm trying to resize a 15GB LVM root partition on a fedora20 server with 
a fedora20 guest and I'm having a problem. Is this supported on fedora20?

I recall having a similar problem (maybe even exact same problem) all 
the way back in fedora16 or fedora17, but hoped/thought it would be 
fixed by now?

What are my alternatives for resizing a root partition on LVM?

I thought this has been already fixed:

I guess updating lvm2. Seems like you won't be able to use pure vgchange 
and do thing by hand anyway.

It looks like that only applies to RHEL6?

Can you track down whether there was a fedora20 update for this?

Do you know where there is a HOWTO of some sort to do it using lvm from 
within the virtual machine? Is that even possible?

Thanks,
