Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

This new parameter allows user specifies where the client cerficate, client key, CA certificate of x509 is, instead of hardcoding it. If 'pkipath' is not specified, and the user is not root, try to find files in $HOME/.pki/libvirt, as long as one of client cerficate, client key, CA certificate can not be found, use default global location (LIBVIRT_CACERT, LIBVIRT_CLIENTCERT, LIBVIRT_CLIENTKEY, see src/remote/remote_driver.h) Example of use: [root@Osier client]# virsh -c qemu+tls://10.66.93.111/system?pkipath=/tmp/pki/client error: Cannot access CA certificate '/tmp/pki/client/cacert.pem': No such file or directory error: failed to connect to the hypervisor [root@Osier client]# ls -l total 24 -rwxrwxr-x. 1 root root 6424 Jan 24 21:35 a.out -rw-r--r--. 1 root root 1245 Jan 23 19:04 clientcert.pem -rw-r--r--. 1 root root 132 Jan 23 19:04 client.info -rw-r--r--. 1 root root 1679 Jan 23 19:04 clientkey.pem [root@Osier client]# cp /tmp/cacert.pem .

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
