Daniel P. Berrangé 1939bcd539 rpc: always pass "-T -e none" args to ssh
Way back in the past, the "no_tty=1" option was added for the remote
driver to disable local password prompting by disabling use of the local
tty:

  commit b32f429849
  Author: Daniel P. Berrange <berrange@redhat.com>

    Added a no_tty param to remote URIs to stop SSH prompting for password

This was done by adding "-T -o BatchMode=yes -e none" args to ssh. This
achieved the desired results but is none the less semantically flawed
because it is mixing up config parameters for the local tty vs the
remote tty.

The "-T" arg stops allocation of a TTY on the remote host. This is good
for all libvirt SSH tunnels as we never require a TTY for our usage
model, so we should have just passed this unconditionally.

The "-e none" option disables the escape character for sessions with a
TTY. If we pass "-T" this is not required, but it also not harmful to
add it, so we should just pass it unconditionally too.

Only the "-o BatchMode=yes" option is related to disabling local
password prompts and thus needs control via the no_tty URI param.

Libvirt API for virtualization

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.

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 2.1 (or later). See the files COPYING.LESSER and COPYING for full license terms & conditions.

Installation

Libvirt uses the GNU Autotools build system, so in general can be built and installed with the usual commands. For example, to build in a manner that is suitable for installing as root, use:

$ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
$ make
$ sudo make install

While to build & install as an unprivileged user

$ ./configure --prefix=$HOME/usr
$ make
$ make install

The libvirt code relies on a large number of 3rd party libraries. These will be detected during execution of the configure script and a summary printed which lists any missing (optional) dependencies.

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:
