This patch adds feature for lxc containers to inherit namespaces. This is very similar to what lxc-tools or docker provides. Look for "man lxc-start" and you will find that you can pass command args as [ --share-[net|ipc|uts] name|pid ]. Or check out docker networking option in which you can give --net=container:NAME_or_ID as an option for sharing namespace. >From this patch you can add extra libvirt option to share namespace in following way. <lxc:namespace> <lxc:sharenet type='netns' value='red'/> <lxc:shareipc type='pid' value='12345'/> <lxc:shareuts type='name' value='container1'/> </lxc:namespace> --- docs/drvlxc.html.in | 18 +++ docs/schemas/domaincommon.rng | 42 ++++++ src/Makefile.am | 4 +- src/lxc/lxc_conf.c | 2 +- src/lxc/lxc_conf.h | 15 +++ src/lxc/lxc_container.c | 236 +++++++++++++++++++++++++++++++++- src/lxc/lxc_domain.c | 164 ++++++++++++++++++++++- src/lxc/lxc_domain.h | 1 + tests/lxcxml2xmldata/lxc-sharenet.xml | 33 +++++ tests/lxcxml2xmltest.c | 1 + 10 files changed, 507 insertions(+), 9 deletions(-) create mode 100644 tests/lxcxml2xmldata/lxc-sharenet.xml diff --git a/docs/drvlxc.html.in b/docs/drvlxc.html.in index a094bd9..d14d4c7 100644 --- a/docs/drvlxc.html.in +++ b/docs/drvlxc.html.in @@ -590,6 +590,24 @@ Note that allowing capabilities that are normally dropped by default can serious affect the security of the container and the host. </p> +<h2><a name="share">Inherit namespaces</a></h2> + +<p> +Libvirt allows you to inherit the namespace from container/process just like lxc tools +or docker provides to share the network namespace.
