Strace of client-glusterfs process during the creation of guestos.

Description of problem: 
Unable to create a guestOS using KVM on a glusterfs mount. The same works for the nfs mount

Version-Release number of selected component (if applicable):
glusterfs 3.3.0qa17

How reproducible:


Steps to Reproduce:
1. Create a volume with replica 2-> vm_replica
2. Mount to volume(vm_replica) from client (Ex: mount-type:glusterfs, mountdir:/mnt/vmstore) 
3. Create a new guestOS using virt-manager. 
4. Select the storage location /mnt/vmstore while creating guestos. 
5. Complete the all steps for creting new guest. Final stage, reports an error. 
  
Actual results:

Unable to complete install: 'internal error Process exited while reading console log output: char device redirected to /dev/pts/2
qemu-kvm: -drive file=/mnt/vmstore/cent.img,if=none,id=drive-ide0-0-0,format=raw,cache=none: could not open disk image /mnt/vmstore/cent.img: Invalid argument
