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.
It turns out that the previous attempt at this doesn't work well
in the case of hotplug. We need qemuCheckPciHostDevice() to
disallow the reset affecting devices already attach to the guest,
but we still need to avoid double locking the virDomainObjPtr.
This is all getting messy, I've a better idea.
This reverts commit 6318808270 and
c106c8a18c.
* src/qemu_driver.c, src/pci.[ch], src/xen_unified.c,
src/libvirt_private.syms: revert a bunch of stuff.
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.
