    LXC: Fix handling of RAM filesystem size units · 1490efc9
    Ján Tomko 提交于
    Since 76b644c3 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:
