Android Studio 2.3 utilisant l'émulateur depuis la console, "périphérique/dev/kvm: autorisation refusée" pour l'utilisateur root

J'essaie de démarrer un périphérique Android virtuel que j'ai créé avec le gestionnaire d'avdmanager de Android Studio 2.3 (via la ligne de commande)

toutes les commandes sont exécutées en tant que utilisateur root

quand j'essaie de démarrer l'émulateur via $ ~/Android/Sdk/tools/./emulator @Nexus_5X_Api_23_x86, la sortie est:

emulator: ERROR: x86_64 emulation currently requires hardware acceleration! Please ensure KVM is properly installed and usable. CPU acceleration status: This user doesn't have permissions to use KVM (/dev/kvm)

J'utilise un serveur Ubuntu 16.04 avec 64 bits, Android Studio est lancé via un transfert x11; mon environnement de bureau est donc utilisé (ce qui est un Ubuntu 16.04, 64 bits aussi!)

quand je tape $ kvm-ok cela me donne:

INFO: /dev/kvm exists KVM acceleration can be used

Pour prouver que le fichier .avd auquel j'essaie d'accéder existe:
$ ~/Android/Sdk/tools/bin/./avdmanager list avd 

donne le résultat:
März 15, 2017 4:30:53 NACHM. Sun.util.PropertyResourceBundleCharset$PropertiesFileDecoder decodeLoop INFO: Invalid or unmappable UTF-8 sequence detected.

plus loin les permissions pour /dev/kvm sont:

root@h2627852:~# ls -l /dev/kvm crwxrwxrwx 1 root kvm 10, 232 Mär 15 10:48 /dev/kvm root@h2627852:~# groups root root : root kvm libvirtd libvirt

effectuer emulator-check me donne:

Je ne sais vraiment plus quoi faire, j'ai cherché dans tout le forum, mais je n'ai pas trouvé de réplique de ce problème pour mon système. Les correctifs du même problème sur d'autres systèmes ne fonctionnaient pas pour moi. purger et réinstaller tous les paquets qemu, libvirt, libvirtd et kvm sans succès. 

Toute aide est appréciée !!

Essayez simplement ceci ... c'est un travail pour moi

$ Sudo chown username -R /dev/kvm

parfois, vous devez aussi exécuter ce code

$ cd Android/Sdk/emulator/lib64/libstdc++
$ mv libstdc++.so.6 libstdc++.so.6.bak
$ ln -s /usr/lib64/libstdc++.so.6

Cela a fonctionné pour moi (je ne sais pas si vous avez toujours le problème)

Install Qemu-KVM and cpu-checker

apt-get install qemu-kvm cpu-checker

Check if KVM is available (as jenkins user

$ kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used

Create group kvm and add <your_user> to this group

addgroup kvm
usermod -a -G kvm jenkins

Change group ownership for /dev/kvm

chgrp kvm /dev/kvm

Create udev rule

$ Sudo nano /etc/udev/rules.d/60-qemu-kvm.rules
KERNEL=="kvm", GROUP="kvm", MODE="0660"

Reboot

Essayez ces étapes:

Installez qemu-kvm comme suit

Sudo apt install qemu-kvm

Ajoutez un utilisateur au groupe kvm à l'aide de la commande suivante:

Sudo adduser <username> kvm

Si vous obtenez autorisation refusée, essayez la commande suivante

Sudo chown <username> /dev/kvm

Cela a fonctionné pour moi dans Ubuntu 18.04
