[lxc-devel] [PATCH 1/1] introduce --lxcpath cmdline option, and make default_lxc_path() return const char *
Serge Hallyn
serge.hallyn at ubuntu.com
Thu Feb 14 16:05:19 UTC 2013
For the lxc-* C binaries, introduce a -P|--lxcpath command line option
to override the system default.
With this, I can
lxc-create -t ubuntu -n r1
lxc-create -t ubuntu -n r1 -P /home/ubuntu/lxcbase
lxc-start -n r1 -d
lxc-start -n r1 -d -P /home/ubuntu/lxcbase
lxc-console -n r1 -d -P /home/ubuntu/lxcbase
lxc-stop -n r1
all working with the right containers (module cgroup stuff).
To do:
* lxc monitor needs to be made to handle cgroups.
This is another very invasive one. I started doing this as
a part of this set, but that gets hairy, so I'm sending this
separately. Note that lxc-wait and lxc-monitor don't work
without this, and there may be niggles in what I said works
above - since start.c is doing lxc_monitor_send_state etc
to the shared abstract unix domain socket.
* Need to handle the cgroup conflicts.
