lxc / docker containers gives option to inherit the
namespaces. Example lxc-start has option [ --share-[net|ipc|uts] name|pid ]
where --share-net name|pid means Inherit a network namespace from a
name container or a pid.
This patch tries to add the similar option to libvirt lxc. So to inherit namespace from
name
container c2.
add this into xml.
<lxc:namespace>
<sharenet type='name' value='c2'/>
</lxc:namespace>
And to inherit namespace from a pid.
add this into xml.
<lxc:namespace>
<sharenet type='pid' value='10245'/>
</lxc:namespace>
And to inherit namespace from a netns.
add this into xml.
<lxc:namespace>
<sharenet type='netns' value='red'/>
</lxc:namespace>
Similar options for ipc/uts.
<shareipc /> , <shareuts />
The reasong lxc xml namespace is added because this feature is very specific to lxc.
Therfore wanted to
keep it seperated from actual libvirt xml domain.
So the final vrish xml file would look like
<domain type='lxc'
xmlns:lxc='http://libvirt.org/schemas/domain/lxc/1.0'>
<name>cn-03</name>
<memory>327680</memory>
<os>
<type>exe</type>
<init>/sbin/init</init>
</os>
<lxc:namespace>
<sharenet type='netns' value='red'/>
</lxc:namespace>
<vcpu>1</vcpu>
<clock offset='utc'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>destroy</on_crash>
<devices>
<emulator>/usr/lib/libvirt/libvirt_lxc</emulator>
<filesystem type='mount'>
<source dir='/var/lib/lxc/u1/rootfs'/>
<target dir='/'/>
</filesystem>
<console type='pty'/>
</devices>
