Commit 4c82f09e added a capability check for qemu per-device io throttling, but only applied it to domain startup. As mentioned in the previous commit (98cec05), the user can still get an 'internal error' message during a hotplug attempt, when the monitor command doesn't exist. It is confusing to allow tuning on inactive domains only to then be rejected when starting the domain. * src/qemu/qemu_driver.c (qemuDomainSetBlockIoTune): Reject offline tuning if online can't match it. (cherry picked from commit 13f9a19326a7727e07ab689ea5392255fbd5cd4f)
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.
