Description of problem:
When trying to install OS on VM , it is paused .

Probably related to RHEL7 , because when switched to RHEL6.5 host, the problem disappeared !
 
Version-Release number of selected component (if applicable):
Red Hat Enterprise Virtualization Manager Version: 3.5.0-0.11.beta.el6ev
vdsm-4.16.3-3.el7.beta.x86_64
libvirt-client-1.1.1-29.el7_0.1.x86_64

How reproducible:
Happens sometime. 

Steps to Reproduce:
setup: I've tested it on 2 setups:
- 1 RHEL7 host, 1 iSCSI SD, and 1 VM 
- 1 RHEL7 host, 1 nfs   SD, and 1 VM
    
1. Create new VM with a thin provisioning disk.
2. Run it .
3. open consol , and chose RHEL 6.5 on cobller menue .
4. continue with the installation.

Actual results:
5. the console freeze at some point (12% of package installation for me).
6. On Admin GUI , the VM is paused.
7. errors on logs, see in additional info below


Expected results:
5. in the console, the installation should end correctly with an active login to the server.

Nir, don't we already have a BZ for this issue (an LVM issue, IIRC)?

Gal, what would help to solve the original bug, is to get the selinux lable of the volume, when you start the installation, and after the error.

Please do this:
1. Create the vm disk
2. Find the the directory where the volume lives
3. Start the vm
4. Run this command

while true; do ls -lZ /path/to/directory >> ls-lz.out; sleep 30; done
  
When the vm pauses, stop this command and upload the ls-lz.out file to the original bug.
