Description of problem:

In New Virtual Machine dialog:

1)
If user assigns profile to NIC and switches DC of new VM on General tab. Profile is removed from the NIC -> that is OK

2)
If user assigns profile to NIC and switches DC of new VM in New Virtual Machine dialog on OTHER than General TAB in advanced options (e.g. Host tab) profile is not removed and error is shown:

Error while executing action:

aaaaaaa:

    The specified Logical Network doesn't exist in the current Cluster.

Version-Release number of selected component (if applicable):
Red Hat Enterprise Virtualization Manager Version: 3.3.0-0.32.beta1.el6ev

How reproducible:
100%

Steps to Reproduce:
1. Have two active DCs with cluster in each
2. Virtual Machines -> New VM -> Fill in VM name, assign rhevm profile to nic1
3. Click on Show Advanced Options
4. Go to Host tab -> switch Cluster -> Click OK

Actual results:
Error appears after confirmation of Create new VM dialog

Expected results:
Red rectangle pointing on General tab -> in general tab user is pointed to select empty profile or profile that actually exists

Additional info:
suggestion: in case default rhevm profile is selected, it might be just silently replaced with default rhevm profile of appropriate DC
