FAQ

Which virtualization technology does IONOS use?

IONOS systems are built on Kernel-based Virtual Machine (KVM) hypervisor and libvirt virtualization management. We have adapted both of these components to our requirements and optimized them for the delivery of diverse cloud services, with a special focus on security and guest isolation.

Which images can I import?

Some software images are only designed for certain virtualization systems. Without VirtlO drivers, VM will not work properly with the hypervisor. You can set the storage bus type to IDE temporarily to install the VirtlO drivers.

How do I install VirtIO drivers for Windows?

For a Windows VM to work properly with our hypervisor, VirtI/O drivers are required.

• Install Windows using the original IDE driver

  You can now install the VirtIO drivers from the ISO provided by IONOS.

• Add a CD-ROM drive to your server

• Select the windows-virtio-driver.iso ISO

• Boot from the selected ISO to start the automatic installation tool

  You can now switch to VirtIO.

For more information, see Install Windows VirtIO drivers.

Can I run a virtualization platform on a Dedicated Core Server?

Our hypervisor informs the guest operating system that it is located in a virtualized environment. Some virtualized systems do not support virtualized environments and cannot be executed on an IONOS Dedicated Core Server. We generally do not recommend using your virtualization technology in virtual hosts.

Can I connect one storage device to multiple servers?

It is not possible to connect multiple servers to one storage device, but you can connect multiple servers in a network without performance loss.

How do I change the Availability Zone of a storage device?

Once a storage device is provisioned, it is not possible to change its Availability Zone. You could, however, create a snapshot and then use it to provision a storage device with a new Availability Zone.

For more information, see Availability Zones.
