Does libvirt support lvm thin > provisioning and thin snapshots? libvirt does not support storage pools containing thin pools. Since commit 4132dede0652b7f0cc83868fd454423310bc1a9c (http://libvirt.org/git/?p=libvirt.git;a=commit;h=4132dede0652b7f0cc83868fd454423310bc1a9c) at least the thick provisioned volumes in such a pool can still be used. Previously, libvirt would just refuse to start the pool. However, you can assign any thin provisioned volume to a VM manually and it will work. On the hardware/software combination that I tried it on (desktop SATA drives in RAID1 on Ubuntu 13.10) it was abysmally slow though. Proper support for LVM thin provisioning would probably need a new storage pool type, and I haven't found any hints that anybody was working on that.
