Since 76b644c when the support for RAM filesystems was introduced, libvirt accepted the following XML: <source usage='1024' unit='KiB'/> This was parsed correctly and internally stored in bytes, but it was formatted as (with an extra 's'): <source usage='1024' units='KiB'/> When read again, this was treated as if the units were missing, meaning libvirt was unable to parse its own XML correctly. The usage attribute was documented as being in KiB, but it was not scaled if the unit was missing. Transient domains still worked, because this was balanced by an extra 'k' in the mount options. This patch: Changes the parser to use 'units' instead of 'unit', as the latter was never documented (fixing persistent domains) and some programs (libvirt-glib, libvirt-sandbox) already parse the 'units' attribute. Removes the extra 'k' from the tmpfs mount options, which is needed because now we parse our own XML correctly. Changes the default input unit to KiB to match documentation, fixing: https://bugzilla.redhat.com/show_bug.cgi?id=1015689 (cherry picked from commit 3f029fb5319b9dc9cc2fbf8d1ba4505ee9e4b1e3)
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.
