How to set up a VM with KVM qemu without VitualBox using Vagrant

Question

I want to use KVM/qemu with Vagrant and the VM managed GUI instead of VirtualBox. So I installed Vagrant ver. 1.9.1. So I read upon it and found that I require vagrant-libvirt for KVM to work with it. So, I installed it next:

$ vagrant plugin list
vagrant-libvirt (0.0.37)
vagrant-share (1.1.6, system)

Next, I to add a CentOS(7) box using vagrant box add "centos/7" and selected libvirt, when prompted. After which, I ran vagrant init and didn't encounter any errors:

After that I added CentOS(7) box in vagrant box using add centos/7 and selected vagrant-libvirt. Then I ran vagrant init without any errors.

$ vagrant init centos/7
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

But vagrant up seems to give error:

$ vagrant up
No usable default provider could be found for your system.

Vagrant relies on interactions with 3rd party systems, known as
"providers", to provide Vagrant with resources to run development
environments. Examples are VirtualBox, VMware, Hyper-V.

The easiest solution to this message is to install VirtualBox, which
is available for free on all major platforms.

If you believe you already have a provider available, make sure it
is properly installed and configured. You can see more details about
why a particular provider isn't working by forcing usage with
`vagrant up --provider=PROVIDER`, which should give you a more specific
error message for that particular provider.

This is the provider section in vagrantfile

config.vm.provider :libvirt do |domain|
    domain.driver = "qemu"
    domain.memory = 512
    domain.cpus = 1
end

I tried changing it to:

config.vm.provider :libvirt do |domain|
    domain.driver = "kvm"
    domain.host = 'localhost'
    domain.uri = 'qemu:///system'
    domain.memory = 512
    domain.cpus = 1
end

And I tried vagrant up --provider=kvm, vagrant up --provider=qemu, and vagrant up --provider=libvirt too, but that too didn't seem to work.

Is there anything here that I'm doing wrong or something that i might have missed.

Edit: After the adding centos/7 using vagrant, it shows up when running vagrant box list.

$ vagrant box list
centos/7 (libvirt, 1611.01)

Start the vagrant box using:

vagrant up --provider=kvm

But maybe your issue is caused by the vagrant ver you're using. It says that vagrant-libvirt plugin is comaptible with vagrant 1.5 to 1.8.
