Disk devices in QEMU have two parts, the guest device and the host backend driver. Historically these two parts have had the same "unique" name. With the switch to using -device though, they now have separate names. Thus when changing CDROM media, for guests using -device syntax, we need to prepend the QEMU_DRIVE_HOST_PREFIX constant * src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Add helper function qemuDeviceDriveHostAlias() for building a host backend alias * src/qemu/qemu_driver.c: Use qemuDeviceDriveHostAlias() to determine the host backend alias for performing eject/change commands in the monitor
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.
