The emulator process for AVD was killed

I just installed Android Studio and created a new AVD. However whenever I try to run it, I get an error message saying the process was killed, and the emulator will close. When running the emulator from cmd I get this message. What is going wrong?
emulator: Android emulator version 30.5.3.0 (build_id 7196367) (CL:N/A)
Warning: Quick Boot / Snapshots not supported on this machine. A CPU with EPT + UG features is currently needed. We will address this in a future release.

Make sure you have enough space in c: drive - Minimum has 20GB free space
If you have already created AVD then go to following location in your windows machine, from command line enter "emulator -list-avds".
C:\Users\username\AppData\Local\Android\Sdk\emulator>emulator -list-avds

Enter emulator #Pixel_2_API_29

You can see emulator launching.
It worked for me - other result found in internet didn't worked for me.

I installed Android Studio and installed HAXM, also I turn off all virtual machines running. When I try to launch the emulator it gives me these errors. What could be the problem? Could it have something in the background virtual machines that are working and I don't know, or could it be SDK path or something in the system environment variables?

I face same error msg.
After reading 'shtolik' advice, then I run command line.
(Thank you very much for your advice ^^)
C:\Users\myname\AppData\Local\Android\Sdk\emulator>emulator -verbose -avd Galaxy_Nexus_API_25
and I found endless of "VCPU shutdown request".
So I search in google.
It seems there is bug at
'Intel® Hardware Accelerated Execution Manager (Intel® HAXM)'
For more details, please see this one.

Facing issue while launching Emulator in Android studio

I have installed Android studio on my system (Windows 10/64 bit).

I am getting this error:

Please help in resolving this.

Android emulator eats large part of your RAM. I would suggest you to use GenyMotion which is very fast and wasy to use.Here is the download link for that
Geny motion.

Please reduce RAM size of your emulator from Android Virtual Device Manager.

UPDATE AFTER CHECKING WITH HAXM 6.0.5
Adding: Intel HAXM 6.0.5 not compatible with windows screenshot:

Please use 6.0.5 HAXM it solved for me. I have i7 and similar issues with 6.0.4

I just wanted to share that I am experiencing the same problem as well with my new Windows 10 computer. How do you add the switch -accel off -verbose to the x86/x64 image? Running an ARM image is extremely slow.

Dealing with the same issue. Something to do with haxm on 7th gen processors as the arm image works.
UPDATE: Confirmed to be a HAXM issue on Kaby Lake, nothing we can do until we get an HAXM update from Intel. Best workaround at this stage is to use the physical device or create a Linux partition. I haven't tested genymotion on a 7th gen processor...can anybody confirm if that works?
