Description of problem:

virt-v2v fails to convert a vm from vmware to rhev if the disk name has a space.

Version-Release number of selected component (if applicable):
Red Hat Virtualization 4.0.5

How reproducible:
100 %

Steps to Reproduce:

1. Create a vm with a space in Disk name on VMware environment. 

2. Try to import this vm to the rhevm environment by connecting to a vmware environment OR by using already added vmware external environment.

Actual results:

Import of the vm fails with below error in the engine.log

"CanDoAction of action 'AddDisk' failed for user admin@internal. Reasons: VAR__ACTION__ADD,VAR__TYPE__VM_DISK,VALIDATION_DISK_ALIAS_INVALID"

Expected results:

Import of the vm should succeed regardless of the space in the disk name OR there should be a option to change the disk name while importing the vm.

Additional info:

Below workaround was used following which vm was imported sucessfully.
Removed the space in the disk name from Vmware environment.

Below are the engine.log when the import of the vm failed.

VMname: SERBVIDOR NOC-007
VM disk name: SERBVIDOR NOC-007.vmdk
