# dcosup

This setup creates a nested VM using libvirt. It then installs Virtualbox and

Vagrant in the VM to use with minidcos](https://minidcos.readthedocs.io).

> NOTE: Currently libvirt only. Support for VirtualBox will be available soon

## Requirements

Install qemu-kvm, libvirt, vagrant-libvirt, and ansible

### Fedora

```

sudo dnf -y install qemu-kvm libvirt vagrant-libvirt ansible

```

You will also need to have kubectl on your system. You can install it by going

to https://kubernetes.io/docs/tasks/tools/install-kubectl/ .

### CentOS

* Run the following:

```

sudo yum install epel-release

sudo yum install qemu libvirt libvirt-devel ruby-devel gcc qemu-kvm ansible

```

* Install Vagrant: https://www.vagrantup.com/downloads.html

* Install the libvirt plugin for vagrant:

```

vagrant plugin install vagrant-libvirt

```

### Nested VM support

Modprobe options:

```

options kvm_intel nested=1 enable_apicv=n

options kvm ignore_msrs=1

```

Reboot the host, and then run the following commands.

```

# want Y to be returned

$ cat /sys/module/kvm/parameters/ignore_msrs

# want N to be returned

$ cat /sys/module/kvm_intel/parameters/enable_apicv

# want Y to be returned

$ cat /sys/module/kvm_intel/parameters/nested

```
