Part 1
The popup about permission was the reason to write part-2, but later I realized there are many more.
After completing activities on Part 1, I now hit the run button to got a pop up saying.
You were previously added to the Hyper-V Administrators security group, but the permissions have not taken effect. Please sign out of your computer for the permissions to take effect.
Yes, this is something related to permission, I read the “sign out of your computer” as “restart the computer“.
When I came again after restarting.
I hit the run button to see the output on 5” Kitkat (4.4) Virtual device.
Again popup episode started.
Popup-1 : Microsoft Visual Studio
The emulator requires an Internet connection to start. Do you want to configure the emulator to connect to the Internet?
Your computer might lose network connectivity while these changes are applied. This might affect existing network operations.
—————————
Yes No
I clicked on Yes
Popup-2 appeared : Visual Studio Emulator for Android
Click “Retry” to run the emulator in elevated mode.
You do not have permission to modify internal Hyper-V network adapter settings, which are required to run the emulator
[Retry] [Close]
I retried and see emulator phone screen, saying “OS starting..”
Output Window Progress…

OMG, It stuck again and displayed me another popup.
The emulator is unable to verify that the virtual machine is running:
Something happened while starting a virtual machine: ‘VS Emulator 5-inch KitKat (4.4) XXHDPI Phone.lima’ failed to start. (Virtual machine ID 618636A2-0A76-46A5-A5BA-0CD352B1BEE5)
‘VS Emulator 5-inch KitKat (4.4) XXHDPI Phone.lima’ could not initialize. (Virtual machine ID 618636A2-0A76-46A5-A5BA-0CD352B1BEE5)
Not enough memory in the system to start the virtual machine VS Emulator 5-inch KitKat (4.4) XXHDPI Phone.lima with ram size 2048 megabytes. (Virtual machine ID 618636A2-0A76-46A5-A5BA-0CD352B1BEE5)
I ran dxdiag and ensured that my system has 4GB RAM (4096 MB), it was double then requirement of 2048 megabytes.
Now what, am I in a war zone between Google and Microsoft? should I gave up or keep trying, lets give it a last try. This time we will run the Visual Studio in elevated mode via “Run as Administrator” option.
I have failed today, following is the output of my work on post 1 and this post.
Visual Studio is saying:
Visual Studio Emulator for Android
The emulator is unable to verify that the virtual machine is running:
Not enough memory is available in the system to start an emulator that uses 2048 MB of startup RAM. Please close other applications and try to launch the emulator again.
If closing other applications doesn’t help, please follow the instructions on this KB article: http://support.microsoft.com/kb/2911380/en-us
The suggested work around is to add a guaranteed MemoryReserve in Registry for Virtualization. Guaranteed means when You run emulator this amount of memory should be always free. I added 1024 as decimal .
Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.
To work around this problem in a system that is running many programs that are using lots of memory, try to close those programs and then restart the emulator.
If the emulator still does not start, you can disable the Hyper-V runtime memory monitoring functionality by adding a MemoryReserve registry. To do this, follow these steps:
- Start Registry Editor.
- Locate the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization
- Right-click the Virtualization folder, point to New, and then click DWORD Value.
- Type MemoryReserve, and then press Enter.
- Double-click MemoryReserve, enter 2048 in the Value data box, select the Decimal option, and then click OK.
- Close Registry Editor.
In systems that experience this problem and that have fewer than 8 GB of RAM installed, a MemoryReserve value of 2048 (2 GB) is recommended. A value of zero (0) causes this registry setting to be ignored.
Note You must restart the computer for this registry setting to take effect.
To close the chapter, I added the desired DWORD MemoryReserve.
When I came again after restarting, the same out of memory story.
I modified the MemoryReserve in Registry for Virtualization to Zero, still , the same out of memory story.
It seems that we need 8 GB of RAM to run default emulator.
Then I decided to create an Galaxy AVD, this time it was a success.
1>Build succeeded.
1>Deploy successfully on AVD_for_Galaxy_Nexus_by_Google.
