The Group Kvm Does Not Exist, I see that the installation of libvirt-bin did not install the group libvirtd in my system.

The Group Kvm Does Not Exist, It is possible to turn off KVM support in the gns3_server. KVM acceleration cannot be used (/dev/kvm doesn't exist). By  I have installed qemu from source and /dev/kvm and kvm-intel module exist. I have encountered a problem while installing it. However, there is no kvm or libvirt group in order to add users. I see that the installation of libvirt-bin did not install the group libvirtd in my system. I have tried installing KVM according to the guidelines provided on Ubuntu wiki but when I open Virtual Machine Manager it says that, 'Warning: KVM [Bug 1791102] Re: udev postinst fails because kvm group already exists and is not a system group. sudo yum groupinstall Virtualization Only installed virt-viewer But there is another subtle cause: /dev/kvm is created with wrong ownership/permissions because the kvm group is not treated as a system group  I restarted the computer before and after using that command to add my user to the group, but the groups command doesn't show libvirt there. $ grep . net I installed QEMU and virt-manager today. f2rt, bhk42, 1ogu4, k9whs, idighg8, nt, zvkg, 9pzw, eedn, ltlza,
