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

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 Guido Günther (4): Introduce virDomainParseScaledValue Introduce filesystem limits to virDomainFSDef openvz: support file system quota reporting openvz: add quota argument when creating container docs/formatdomain.html.in | 14 +++ docs/schemas/domaincommon.rng | 12 +++ src/conf/domain_conf.c | 124 ++++++++++++++++------- src/conf/domain_conf.h | 2 + src/openvz/openvz_conf.c | 24 +++++ src/openvz/openvz_driver.c | 58 ++++++++++- tests/domainschemadata/domain-openvz-simple.xml | 2 + 7 files changed, 199 insertions(+), 37 deletions(-) -- 1.7.10
