Re: [lxc-users] Difference in using network namespace via ip command and lxc

Thanks @serge for the reply. So we cannot create a namespace without binding it to a process then ? On Fri, Jun 27, 2014 at 10:49 PM, Serge Hallyn wrote: > Quoting Ajith Adapa (ajith.ad...@gmail.com): >> Hi, >> >> I am quite new to network namespaces and just making my hands dirty >> using ip co

Re: [lxc-users] Setting a limit on the disk size that a container can use

On second thought, DON'T use scst/LIO in loopback configuration. Or any other inititator-target configuration in the same host where both initiator and target are in-kernel (this includes nfs). Using these kind of setup can lead to memory allocation deadlock. It should be fine for testing/migratio

Re: [lxc-users] Packet flow from application running in container to physical NIC transmission

Dear Mohit, you're welcome. The LXC project is a "meta project" which has bundled and is based on a couple of other work, e.g. from the teams of the kernel or the cgroup developers. From that, no all userland stuff is LXC-aware yet. The LXC team know about, point this out to other package maint

Re: [lxc-users] Packet flow from application running in container to physical NIC transmission

Thanks a Lot Jäkel, it clarifies a lot of doubts for me. What will be output of dmesg from the container? Is it same as host output or it will show the container bootup sequence. On Fri, Jun 27, 2014 at 5:21 PM, Jäkel, Guido wrote: > Dear Mohit, > > Please look out for some slide shows or blog

[lxc-users] Difference in using network namespace via ip command and lxc

[lxc-users] zfs snapshot point

Currently when using lxc-snapshot the snapshot point is the rootfs dataset. (so something like /lxc/foo/rootfs) I'm trying to understand why the dataset doesn't also include the config file (so /lxc/foo/). Isn't that file also needed to reconstitute a snapshot, or is that information duplicate

Dear Mohit, Please look out for some slide shows or blog articles about LXC. Maybe the following may help you to master the first hurdles, too: * The "templates" are used to set up a (more-or-less) key-ready root filesystem of some Linux distribution. They wil act as a bootstraper and will dow
