I'm running REDHAWK 1.10 on a CentOS6.5 VM. I have the connection set to bridged and can locate the USRP by its IP address using: uhd_find_devices --args="addr= <ip address>"
I have a usrp2 with serial E5R1AS2UP
Here are the steps I take:
$ sudo $OSSIEHOME/bin/cleanomni
$ nodeBooter -D -debug 5
$ nodeBooter -d <location to USRP_UHD node>.xml -debug 5
I have also run these commands as requested by the USRP:
sudo sysctl -w net.core.rmem_max=50000000
sudo sysctl -w net.core.wmem_max=1048576
Relavant Console output thus far:

- In the IDE, I click connect to REDHAWK_DEV, and start the device running under the custom node that I created.
By monitoring the ports of the USRP_UHD device, I see that my dataFloatTX_IN / dataShortTX_IN is 0 E/s as well as the rest of the columns, all of the other rows and columns are blank. This is strange since I want to RX and not TX; I had the FRONTEND::tune_allocation settings set to:
center freq = 9.91e7
bandwidth = 1.0e6
sample_rate = 1.0e6
tuner_type = RX_DIGITIZER
So then I tried using the steps outlined by pwolfram here: USRP_UHD source and sink for redhawk
I now have a waveform that contains a dataConverter as the assembly controller, AMFMDEMOD (2), and dataWriter (3). Running the waveform gives the error:
2014-08-22 14:46:25 ERROR ApplicationFactory_impl:1463 - Error in application creation; Failed to satisfy 'usesdevice' dependencies DCE:0dd76dd3-b44e-4e6a-b44a-896980682972for application 'USRP_Wave_234_134622508'
I saw that this was in the usesdevice line so I double checked to make sure that the usesdevice id is equal to the ID of the USRP_UHD device, and that the frontend ID and USRP ID both match the DCE in the properties view.

Solution:
Next step is to make sure your GPP is running. The spd of the waveform needs to be edited as such:
<usesdevicedependencies>
<propertyref refid="DCE:<default value>" value="FRONTEND::TUNER"/>
The ::TUNER part needs to be added as it appears in your USRP_UHD properties tab.
Afterwards, you will have to adjust the values that you tune to based on whichever USRP you are using. The waveform then needs to be exported to the target sdr and then it can be launched. Using a trace on the node will tell you if your values need to be adjusted. I also removed the datawriter from the waveform because of how large the generated files were.
