How to Install Xen from http://www.xenproject.org/ on OpenSUSE Latest

Xen is an open-source virtualization platform that provides a powerful and efficient means of creating and managing virtual machines. In this tutorial, we will guide you on how to install Xen on OpenSUSE latest.

Prerequisites

Before we proceed, make sure that you have the following:

• OpenSUSE version latest installed on your system.

Step 1: Update the System

The first thing you need to do is to update your system.

sudo zypper update

This command will update your system's package repository, and you will have the latest available packages.

Step 2: Install Xen

To install Xen, run the following command in the terminal:

sudo zypper install xen

This command will install the Xen hypervisor and its associated tools on your system.

Step 3: Configure the Xen Hypervisor

Before we start using the Xen hypervisor, we need to configure it by setting the default kernel, bootloader, and other parameters. Run the following commands in the terminal:

Set the default kernel:

sudo sed -i 's/GRUB_DEFAULT=.*/GRUB_DEFAULT=0/g' /etc/default/grub

Update the bootloader:

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

Set the parameters for the Xen hypervisor:

sudo sed -i 's/#kernel=k/k/g' /etc/xen/xend-config.sxp
sudo sed -i 's/#(hd0)/\1/g' /etc/xen/xend-config.sxp
sudo sed -i 's/^[# ]*xend-http-server.*$/xend-http-server = no/g' /etc/xen/xend-config.sxp
sudo sed -i 's/^[# ]*xend-unix-server.*$/xend-unix-server = yes/g' /etc/xen/xend-config.sxp

After running these commands, Xen hypervisor is now configured on your system.

Step 4: Create a Virtual Machine

Now that we have installed and configured Xen, we can create virtual machines. To create a virtual machine, we can use the virt-install command.

For example, to create a virtual machine with 1GB RAM, 10GB disk space, and 2 CPUs, run the following command:

sudo virt-install \
    --name=myvm \
    --ram=1024 \
    --disk path=/var/lib/libvirt/images/myvm.img,size=10 \
    --vcpus=2 \
    --os-type=linux \
    --os-variant=rhel7 \
    --network network=default \
    --graphics=vnc \
    --console=pvc \
    --boot=hd \
    --extra-args='console=tty0 console=ttyS0,115200n8'

Replace myvm with your desired virtual machine name, and adjust the memory, disk space, and CPU according to your requirements.

Conclusion

In this tutorial, we have demonstrated how to install Xen on OpenSUSE latest and create a virtual machine. With the power of Xen, you can easily manage and deploy multiple virtual machines on your system.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
