[libvirt] [PATCHv3 0/4] Support filesystem limits for containers

[Guido Günther]

Hi,
the following patches are a third stab at filesystem limits for
containers. With these patches space limits in openvz containers are
printed in the domain config as:

<filesystem type='template' accessmode='passthrough'>
      <source name='debian'/>
      <target dir='/'/>
      <space_hard_limit unit="MiB">1153024</space_hard_limit>
      <space_soft_limit unit="MiB">1048576</space_soft_limit>
</filesystem>

The can also be set from the domain xml. I left out inode limits for now
since the unit "Bytes" wouldn't fit there well and I didnt' get around
to update the unit parsing code yet. Changes since last time:

* Add the version we introduced this feature to formatdomain.html.in
* Move the patch that makes virDomainParseMemory use
  virDomainParseScaledValue to the front of the queue
* Fix safe_node -> save_node typo
* Make output format consistent with what's used in storage_conf.c
  ('bytes' not 'B')
* openvz: Check for overflow when parsing DISKSPACE out of the container
  config
* openvz: Fix logic that only sets the hard limit when no soft limit is
  given and rejects config that only specify a soft limit

Cheers,
 -- Guido
