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.
Some of our operation denied messages are outright stupid; for
example, if virIdentitySetAttr fails:
error: operation Identity attribute is already set forbidden for read only access
This patch fixes things to a saner:
error: operation forbidden: Identity attribute is already set
It also consolidates the most common usage pattern for operation
denied errors: read-only connections preventing a public API. In
this case, 'virsh -r -c test:///default destroy test' changes from:
error: operation virDomainDestroy forbidden for read only access
to:
error: operation forbidden: read only access prevents virDomainDestroy
Note that we were previously inconsistent on which APIs used
VIR_FROM_DOM (such as virDomainDestroy) vs. VIR_FROM_NONE (such as
virDomainPMSuspendForDuration). After this patch, all uses
consistently use VIR_FROM_NONE, on the grounds that it is unlikely
that a caller learning that a call is denied can do anything in
particular with extra knowledge which error domain the call belongs
to (similar to what we did in commit

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.
