This patch introduces a common function to verify if the availability of the so-called Secure Guest feature on the host has changed in order to invalidate the qemu capabilities cache. It can be used as an entry point for verification on different architectures. For s390 the verification consists of: - checking if /sys/firmware/uv is available: meaning the HW facility is available and the host OS supports it; - checking if the kernel cmdline contains 'prot_virt=1': meaning the host OS wants to use the feature. Whenever the availability of the feature does not match the secure guest flag in the cache then libvirt will re-build it in order to pick up the new set of capabilities available.

It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor. For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users. Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP. Further information about the libvirt project can be found on the website: https://libvirt.org License ======= The libvirt C API is distributed under the terms of GNU Lesser General Public License, version 2.1 (or later). Some parts of the code that are not part of the C library may have the more restrictive GNU General Public License, version 2.0 (or later).

Installation ============ Instructions on building and installing libvirt can be found on the website: https://libvirt.org/compiling.html Contributing ============ The libvirt project welcomes contributions in many ways. For most components the best way to contribute is to send patches to the primary development mailing list. Further guidance on this can be found on the website: https://libvirt.org/contribute.html Contact ======= The libvirt project has two primary mailing lists: * libvirt-users@redhat.com (**for user discussions**) * libvir-list@redhat.com (**for development only**) Further details on contacting the project are available on the website: https://libvirt.org/contact.html
