Re: [Lxc-users] Using VMware as a test-bed for hosting lxc containers. [SOLVED]
Greetings, Apologies for being a bonehead. the routing table in the container was problem #1, plus it turns out that I also forgot to turn on ip routing inside the vm. DOH! Anyway, thanks so much for your help. Have a good day. Date: Fri, 7 Sep 2012 11:35:06 +0700 Subject: Re: [Lxc-users] Using VMware as a test-bed for hosting lxc containers.

If you use latest ubuntu it'll work out of the box. I've also got iptables configured to do the masquerading for the br0 device: I usually just let lxc or libvirt create lxcbr0/virbr0, with the necessary rules. Much simpler that way.

[Lxc-users] lxc staging branch on github
Hello everyone, As you probably noticed Serge and I have been trying to keep up with all the changes going to the lxc-users and lxc-devel mailing lists with some varying success. For quite a while now Serge has been maintaining a separate git branch on github where he'd merge the changes that we're using in Ubuntu and then regularly ask Daniel to review the branch and merge into the master branch on sourceforge. To try and make this all a bit more official, I took ownership of the lxc project on github at: https://github.com/lxc We now have an lxc repository at: https://github.com/lxc/lxc With the main branch being called staging and containing what used to be in Serge's tree. This should now make it pretty easy to contributors to branch and send over pull requests. We'll continue monitoring the mailing-lists and merging the changes proposed on there as soon as it seems we reached an agreement. It'd be great if anyone who submitted changes on the mailing-list or through any other mean could check that their changes are in the staging tree and if not, re-submit the change so we can include it. @Daniel: Please let me know if you have a github account so I can add you to the project admins. -- Stéphane Graber Ubuntu developer http://www.ubuntu.com signature.asc Description: OpenPGP digital signature -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Lxc-users] Ephemeral disk space redux: adding --overlaydir option to lxc-start-ephemeral?

Maybe I'll add an argument --overlaydir PATH for where to store the files; if that's set, setup_container() will use that rather than doing OVERLAY_DIR=`mktemp -d /tmp/lxc-lp-XXX` sudo mount -t tmpfs none $OVERLAY_DIR For safety, I would create a subdirectory inside the specified directory, and use that for $OVERLAY_DIR. That would let me clean up that directory before and after runs without worrying about accidentally destroying the host system if the user makes a typo. Kinda like the attached patch. (It's a little dirty. I'll try to send a clean one once I've actually used it in production for a while.) Hi Dan, Sorry for not replying to this e-mail earlier. I have now pushed lxc-start-ephemeral to the github staging branch as a python3 script using the new LXC API rather than as a shell script. I'll add myself a todo item to port your change to the python version. Looking at it, it shouldn't be too difficult to do, though I'm not sure how that option should work when you have more than one overlayfs (when you have bind mount entries in the source container's fstab). -- Stéphane Graber Ubuntu developer http://www.ubuntu.com signature.asc Description: OpenPGP digital signature -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Woot! I'll add myself a todo item to port your change to the python version. Looking at it, it shouldn't be too difficult to do, though I'm not sure how that option should work when you have more than one overlayfs (when you have bind mount entries in the source container's fstab). Another wrinkle: I have since discovered that badly behaved client systems can produce overlay directories that are hard to clean up (e.g. it takes too long to delete the million fifos one left behind in /tmp), so I may change the script to create a filesytem using loopback mount on a file. This is getting kind of complex, especially the cleanup! - Dan -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
