Bug 1370284

Description of problem:
I was doing a deployment of:

   RHV(self hosted, 4 hosts) + OSE(3 nodes) + CFME

It got through the RHV and OSE deployment but failed in the CFME deployment with the following error:

CFME Launch failed with error ["Failed to power up a compute thistimeitwillwork-RHEV (RHEV) instance thistimeitwillwork-cfme.b.b: Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details:, The host hosted_engine_1 did not satisfy internal filter Memory because its available memory is too low (3083.000000 MB) to run the VM., The host hosted_engine_1 did not satisfy internal filter Memory because its available memory is too low (3083.000000 MB) to run the VM., The host hosted_engine_1 did not satisfy internal filter Memory because its available memory is too low (3083.000000 MB) to run the VM., The host hosted_engine_1 did not satisfy internal filter Memory because its available memory is too low (3083.000000 MB) to run the VM."]

Note, the commas after "VM.".

This is a total nit, but it does look weird.  Also, with the error showing up in a single line scroll bar it really unwieldy.   Perhaps a text field with
a few more lines would help too, because then you could put each error on a 
separate line.

Note, this is the display for the particular task being done.

Version-Release number of selected component (if applicable):
QCI-1.0-RHEL-7-20160824.t.1

How reproducible:
I think always

Steps to Reproduce:
1.  Do a RHV + OSE + CFME deployment where there is not quite enough memory 
    left on the first RHV host.

Actual results:
It fails with the error above.

Expected results:
Minimally the commas should not be after the periods.   A larger text box for the error display would be helpful.
