Libvirt Qemu appears as user in login screen and user switch menu

[jeremy-list]

The system user libvirt-qemu set up by libvirt has user id 64055, which causes all other software on the system to treat it as a regular user (including listing it on the login screen and other lists of users)

Status changed to 'Confirmed' because the bug affects multiple users.

Are there any updates on this bug?

I had been facing the same problem along with one more user account named "No value has been set".
For "Libvirt Qemu" tried purging "qemu-kvm" and it's configuration files. But still user account was existed. I had been trying for the solution and found one that you can also try. (I'm using linux mint 18.2 Sonya)

Go to location /etc/ as root and find a file named "passwd" and open it. Now find the line
"libvirt-qemu:x:64055:132:Libvirt Qemu,,,:/var/lib/libvirt:/bin/false" (see the image I attached not to get confused, values may vary in your case) and clear it (don't clear any other line which is not related to "libvirt-qemu"). I found that line almost at the end of the list.

If you're having one more user account named "No value has been set" then clear the line below:
"<admin name>:x:1001:1002:No value has been set:/dev/null:/dev/null" (values may vary in your case)

And now I don't have these user accounts or any other issue after removing those values: "libvirt qemu" and "No value has been set"
