[libvirt-users] virt-install: failed to initialize KVM: Permission denied
As a regular user, member of the libvirt group, I run this command to create a basic VM: virt-install --connect qemu:///system --name=test --ram 2048 --cpu host-model-only --os-variant=win7 --disk /myVM/test --boot cdrom,hd --virt-type kvm --graphics spice --controller scsi,model=virtio-scsi --cdrom=/drawer/myIso/w8.iso It returns an error : --------------------------------- Starting install... ERROR internal error: process exited while connecting to monitor: Could not access KVM kernel module: Permission denied failed to initialize KVM: Permission denied --------------------------------- $ getfacl /dev/kvm # file: dev/kvm # owner: root # group: kvm user::rw- user:martinus:rw- group::rw- mask::rw- other::--- The command return seems to indicate rights are correct. $ lsmod return kvm & kvm_intel are loaded. If I run the virt-install with qemu:///session, I do not have this issue and can create the VM. I found many entries about the KVM permission issue, but with no clear answer to solve it.

$ getfacl /dev/kvm

It depends on how your libvirt was built (configured), what's the default user/group under which the machines are ran. Let's say it's being ran under qemu. Check that user qemu is in the group kvm and if not, adding it there should fix it for you. Whether the user should be in that group (by default) or not depends on the configuration of other packages in your system as well. I think on my system the qemu package adds qemu user, kvm group and adds qemu user into the kvm group, but this is just a guess from my side. Your system may be using some *Kit and other things to set that. I'm just trying to say that even if my solution helps you, it might not be what your distribution packagers had in mind and the root cause is somewhere else. Martin P.S.: You can also change the default user/group under which qemu will be started in /etc/libvirt/qemu.conf, but I guess that's not what you want.
The command return seems to indicate rights are correct. $ lsmod return kvm & kvm_intel are loaded.
If I run the virt-install with qemu:///session, I do not have this issue and can create the VM.
