wp8.1 emulator troubleshooting – Windows Phone OS is starting OR Loading OR freezes

I had lots of issues with getting wp8.1 emulator working with visual studio 2013 update 4, although it worked fine with a physical device.
Challenge is that emulator creates virtual machines and then it is a network connection over to the virtual machine.
Looking at the hyper-v manager, I could see that the virtual machine had been created ok, and VSExpress 2013 was starting it ok (and it stopped and restarted each time I hit debug in VSExpress).
My problem was that we use F-secure as a firewall and it was blocking communication.

My fix: activated airplane mode, disabled firewalls then tried again.
2 minutes in, everything was ok – vm had been created (I was deleting them and the virtual switch before starting each run) and connection had been made.
Second time took 5 seconds to run.

I then switched firewall back on, airplane mode off. Even internet worked.
The only thing it did not seem to survive was an overnight sleep state – but that’s ok.

Note, if I use windows firewall, this already ships with the right port rules – but I could not see anything to do with VS or xde, so must be the generic hyper-v ones.

Really difficult for me to see which are the origin ports, as these are dynamically generated. But I can see that on the emulator it is port 135.

OTHER TROUBLESHOOTING
Along the way, I came across many useful sources of info…

Simple fix might be to plug in the physical LAN cable – don’t ask, just the way hyper-v virtual switches work… (something to do with sharing same MAC).

One possible reason for the behavior you are observing is corrupt Hyper-V settings. To correct that, please follow these steps:

1. Close Visual Studio.
2. Open the Hyper-V Manager.
3. Delete all Emulator virtual machines.
4. From the Virtual Switch Manager, delete all Windows Phone Emulator-related switches.
5. Start Visual Studio and try deploying to the Emulator.

When I did that I then got the error: “you do not have permission to modify internal hyper-v network adapter settings, which are required to run the emulator”

Hit retry – but then it paused on the “Windows Phone OS is starting”.

I then tried other format emulators – did not work.

I then tried launching from the command line – works, but then you do not get the connection between the two:
“c:\Program Files (x86)\Microsoft XDE\8.1\xde.exe” /name “Emulator 8.1 U1 1080P 6 inch.myusername” /displayName “Manual” /video “1080×1920”

My actual command line when executed from visual studio:
“C:\Program Files (x86)\Microsoft XDE\8.1\XDE.exe” /name “Emulator 8.1 U1 1080P 6 inch.myusername” /displayName “Emulator 8.1 U1 1080P 6 inch” /vhd “C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v8.1\Emulation\Images\flash.update1.vhd” /video “1080×1920” /memsize 2048 /diagonalSize 6 /language 409 /bootlanguage 409 /creatediffdisk “C:\Users\myusername\AppData\Local\Microsoft\XDE\8.1\dd.1080×1920.2048.60.gdr1.vhd” /snapshot /fastShutdown

I was running on a domain where I am not the admin of the domain (that’s why I think I had lots of problems with hyper-v user privileges. Even adding the domain user in via mmc did not help (note: need to be connected to the domain to do that – otherwise you can only add local users).
Good luck!
