To run PVMs, a machine with the Protected Virtualization feature, as
indicated by the Ultravisor Call facility (stfle bit 158), is
required. The Ultravisor needs to be initialized at boot by setting
-`prot_virt=1` on the host's kernel command line.
+``prot_virt=1`` on the host's kernel command line.
Running PVMs requires using the KVM hypervisor.
-If those requirements are met, the capability `KVM_CAP_S390_PROTECTED`
+If those requirements are met, the capability ``KVM_CAP_S390_PROTECTED``
will indicate that KVM can support PVMs on that LPAR.
-----------------------------------
To run a PVM you will need to select a CPU model which includes the
-`Unpack facility` (stfle bit 161 represented by the feature
-`unpack`/`S390_FEAT_UNPACK`), and add these options to the command line::
+``Unpack facility`` (stfle bit 161 represented by the feature
+``unpack``/``S390_FEAT_UNPACK``), and add these options to the command line::
-object s390-pv-guest,id=pv0 \
-machine confidential-guest-support=pv0
Adding these options will:
-* Ensure the `unpack` facility is available
+* Ensure the ``unpack`` facility is available
* Enable the IOMMU by default for all I/O devices
* Initialize the PV mechanism
components (kernel, initrd, cmdline), the stage3a loader and
metadata. In case this boot method is used, the command line
options -initrd and -cmdline are ineffective. The preparation of a PVM
-image is done via the `genprotimg` tool from the s390-tools
