While Xen only has a single paravirt console, UML, and QEMU both support multiple paravirt consoles. The LXC driver can also be trivially made to support multiple consoles. This patch extends the XML to allow multiple <console> elements in the XML. It also makes the UML and QEMU drivers support this config. * src/conf/domain_conf.c, src/conf/domain_conf.h: Allow multiple <console> devices * src/lxc/lxc_driver.c, src/xen/xen_driver.c, src/xenxs/xen_sxpr.c, src/xenxs/xen_xm.c: Update for internal API changes * src/security/security_selinux.c, src/security/virt-aa-helper.c: Only label consoles that aren't a copy of the serial device * src/qemu/qemu_command.c, src/qemu/qemu_driver.c, src/qemu/qemu_process.c, src/uml/uml_conf.c, src/uml/uml_driver.c: Support multiple console devices * tests/qemuxml2xmltest.c, tests/qemuxml2argvtest.c: Extra tests for multiple virtio consoles. Set QEMU_CAPS_CHARDEV for all console /channel tests * tests/qemuxml2argvdata/qemuxml2argv-channel-virtio-auto.args, tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.args tests/qemuxml2argvdata/qemuxml2argv-console-virtio.args: Update for correct chardev syntax * tests/qemuxml2argvdata/qemuxml2argv-console-virtio-many.args, tests/qemuxml2argvdata/qemuxml2argv-console-virtio-many.xml: New test file
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.

Description
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.
