i'm not sure it's possible with virtio-blk. 

virtio-scsi seem to support it in qemu git. 

I'll make some tests today with .raw files to see what is possible.



BTW, I would like to implement resize of volume in proxmox for the future, could you describe how to resize an lvm device ?

Hello list, 

is online resizing of virtio blk devices supported? It seems Redhat 
itself supports it: 
https://bugzilla.redhat.com/show_bug.cgi?id=648594 

I've resized the LVM block device outside of the VM but inside the VM 
i've no idea how to get the new size.
