When i run emulator, i get the following error:
Cannot launch AVD in emulator.
Output: Hax is enabled qemu-system-x86_64.exe: -drive if=none,index=1,id=cache,file={path_to_SDK}\SDK.android\avd{AVD_name}.avd/cache.img: could not open disk image {path_to_SDK}\SDK.android\avd{AVD_name}.avd/cache.img:
Could not open '{path_to_SDK}\SDK.android\avd{AVD_name}.avd/cache.img':
Invalid argument
Hax ram_size 0x40000000
HAX is working and emulator runs in fast virt mode. Error accepting connection, aborting
AVD specs are:
OS: Android 6.0 Google APIs
RAM: 1GB
Resolution: 1440x2560
Running on Android Studio 2.0 Beta 6, Windows 10.

Keep an eye out for a background qemu-system-i386.exe process running in the background that will be locking the cache.img file.
This might be still running from a previously failed emulator launch. Kill that using Task Manager and start again.

I had the same problem already twice since I upgraded to Android Studio 2.0 on Windows 10. I use a preferred emulator in the Run/Debug configuration. Changing the Deployment Target Options in the configuration to Target: Show Device Chooser Dialog solved it for me. After choosing the same emulator instance in the dialog it started with no problem. Then I change back to the preferred emulator setting. Until the next time it breaks...
Hoping this helps.

I faced the same problem in Windows 10.
Clearing temp and %temp% folder followed by a restart of machine solved my problem.
Hope this helps.

I had this problem, when I didn't notice that emulator is already running :)
