Text content

hvm

Indicates that the operating system needs full virtualization.

Selected attributes

arch=s390x

Specifies the system architecture.

machine=s390-ccw-virtio | <machine-type>

Specifies the machine type. If you specify the alias machine type s390-ccw-virtio, libvirt replaces this value by the current machine type, which depends on the installed QEMU release on the host or on the hypervisor release. Use this value unless you intend to migrate to a host with an earlier hypervisor release.

If you intend to migrate the virtual server to a destination host with earlier hypervisor release than the source host, specify the machine type reflecting this earlier release.

To display the available machine types, enter:

# qemu-kvm --machine help

Usage

• Definition of a virtual server on different hosts using the same configuration-XML
