Problem with disk mounting after installing lvm

Hello.

I honestly read all rules and try to find answer in this forum and in google.)))) But with no luck!

I wanted to try emergency password, implemented in kali 1.0.6. So, I install kali on virtualbox and select "Guided – use entire disk and set up encrypted LVM" in "Partition disks" section. After successull installing, kali loaded and tells "unable to mount 13 GB unrecognized, one or more blocks devices are holding /dev/dm-0". I have not much expereince in Linux troubleshouting, so I ask to help me troubleshoot this issue. I will be monitoring this post, sa I can quikly present the output of commands that you, I hope, will advise.

Thank to all.
