I could resolve this issue by adding my user to kvm and libvirtd groups.
$ sudo adduser `id -un` kvm $ sudo adduser `id -un` libvirtd
I believe the installer either should suggest adding the user to these groups or virt-manager should become root by asking credentials at startup.
After adding myself to groups, I got stuck at the following reported problem: https://bugs.launchpad.net/ubuntu/+source/virt-manager/+bug/920853
