In linux? `/var/log` maybe? Or https://stackoverflow.com/questions/19784877/how-to-find-the-logs-on-android-studio — OneCricketeer, Jun 19 '17 at 16:56

Changed permissions in the /home/folder/Android/Sdk/emulator/ folder

chmod 777 -R /home/folder/Android/Sdk/emulator/

Permissioned denied to which user? 777 seems excessive – OneCricketeer Jun 19 '17 at 19:49
From android studios all users even root could not access most of the files in the Sdk folder. Instead of 777 which level is best, 555(r-x)? – Minathe Jun 24 '17 at 14:54
Ubuntu 18 'sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils' – rafaelphp May 23 '18 at 18:45

The only items you need to change are `chmod 775 ~/Android/Sdk/emulator/emulator* ~/Android/Sdk/emulator/qemu/linux-x86_64/qemu-system-*` If you try running the emulator from the command line `~/Android/Sdk/emulator -avd (your avd name)` you can easily see any errors (use -list-avds to find your avd name). Seems strange that the emulator files are not executable by default? – Victor Rendina Jun 22 '18 at 02:20

I also had this problem, and was able to fix it by using:

sudo chmod 777 /dev/kvm

In my case the error was because the user has not enough permission to /dev/kvm. So the solution is giving permission,i.e.,

chmod 777 /dev/kvm

You need to be part of the kvm group

Try this:

sudo adduser $USER kvm

Then relaunch android studio or unlog / relog user
