Version-Release number of selected component (if applicable):
RHEL 7.1 (default installation) as hypervisor
RHEV-M 3.5.3.1-1.4.el6ev deployed as self-hosted engine

How reproducible:
Create a VM with Russian letters. The creation process fails on disk creation stage if Russian characters are used in Disk Name Field. If manually change the Russian characters to English in Disk Name Field, a VM will be created, but can not be started.

Steps to Reproduce:
1. Create a new VM with Russian characters in Name Field. 
2. The creation process fails on disk creating stage with Russian letters.
3. If manually change Disk Name Field to English letters, a VM will be created, but can not be started.

Actual results:
A VM can not be created and started if Russian characters are used in VM Name Field. 

Expected results:
A VM can be created if Russian characters are used in VM Name and Disk Name fields.
