Looks like that requires vzctl 4.1 (Debian how has 3.0.30 ). https://bugzilla.redhat.com/show_bug.cgi?id=866495 I'm curious if vzctl version can be updated before Wheezy release. Basically current vzctl can't be used in Wheezy because of the lack openvz compatible kernel.

Have a look at libvirt: Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). The library aims at providing a long term stable C API for different virtualization mechanisms. It currently supports QEMU, KVM, XEN, OpenVZ, LXC, and VirtualBox.

I can't find a way to share IP address with the host system. Here is my use cases: 1) I have bgpd running on a host server which advertises 10.7.7.5/32 10.6.6.5/32 Then I tell linux-vserver to have these IPs on eth0, eth1 whatever, and I don't need to create routes, nat, etc - packets reach the instance. 2) I have 192.168.1.2/28 and 3ffe::2/120 on the eth0 from a hoster, from there I create containers with 192.168.1.3/32 and 3ffe::3/128 which are attached to eth0 - packets reach the instance. Unfortunately I can't have such setup with LXC. If one is aware what to do, please tell me. Another question, is there a 'unofficial' linux-vserver debian repo for wheezy? If not, how it hard to have personal automated kernel build farm? Any ready to use solutions? -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

We use both KVM and VServer in our environment on hefty hardware. Not only do the lower requirements make a difference on highly virtualized systems (nothing like seeing dozens of small servers running in 8MB of RAM) but there are interesting advantages that can be gained from the shared file system and the ability to remount portions of the host file system into the guests. So we certainly see the need for both. The VServer team is incredibly talented and helpful but also very small so we are keeping our eyes closely on LXC.

This was recently discussed on -devel, and several people commented that there isn't yet good userland support for the LXC container mechanism. At present, there are no plans for vserver or openvz kernel packages in wheezy, so wheezy is not going to have any well-supported container mechanism. Many might feel that this is a problem. I think that the kernel maintainers may be short of time for supporting the other versions. Personally, I'm moving all our (non-Debian) vservers to KVM virtual machines, despite not being as lightweight, for two main reasons: one, the advantage of having distinct kernels per instance; two, the weightiness is not a problem on the newer hardware we have. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

Well, I haven't used them yet, but looking at the lxc package's filelist [1], it looks like there is a /etc/init.d/lxc script which might start the containers at boot. And indeed, downloading the package and looking at the files, /etc/init.d/lxc contains references to /etc/default/lxc (which I imagine is used to configure some stuff) and also to /etc/lxc/auto/* (which I think is the way to tell lxc what containers to auto-start at boot; looks similar to the way xen does it). 1. http://packages.debian.org/wheezy/i386/lxc/filelist -- Adrian Fita -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

linux-vserver (or equvalent) in wheezy
Hi! Could you please tell me what is the option now should be used instead of linux-vserver in wheezy? Looks like there is no kernel with linux-vserver for wheezy. I'm aware about KVM, but we understand it's not the same. I'm looking for lightweight containerization like linux-vserver which works out of the box in wheezy.
