[Vserver] LinuxTag 2006
Hi everyone, as most of you will know, we had a booth a Linuxtag 2006 which took place in Wiesbaden from May 3rd to 6th. Kudos go to DerJohn who organized the whole thing. At the booth we had some servers running VServer in a 19'' rack and a multi-seat workstation which had the individual seats running inside it's own VServer each. Bertl arrived late on Thursday and held a talk on Friday. It was supposed to be a hands-on workshop, but too few people remembered to bring their laptops with them. So Bertl shared his wide and deep knowledge and many people listened interestedly for three hours. At the booth, we had to personally answer questions to anyone who wondered what 'Linux-VServer' might be, as we yet have to develop nice pictures to hang inside such a booth that will explain what this does. Nonetheless, we had lots of opportunity to demonstrate VServer in it's simplicity and potency and many people seemed ti be genuinely interested to try it out. The aforementioned multi-seat workstation was devised by Zeng. It had three graphics adaptors (or was it four?) and as many keyboards, mice and speakers. The displays were connected to a graphics adater each, the KMS were connected via USB. It was easily possible to work on all three seats, even gaming was fun at these machines. But the best thing was to demonstrate what VServer will do for a multi-seat: do a kill -9 -1 in root-context and you only kill the seat you got root for. This setup was the piece of attraction at our booth, even Mark Shuttleworth called it 'amazing technology'. Zeng said he is determined to follow this through. Next time, he'll need his own booth for the Linux VDesktop Project :) Another new thing we could show was a web-management application that a friend of Ben_ wrote for VServer. The thing is able to manage multiple host servers and their respective guest servers. A lot of suit and tie-types specifically asked for management interfaces and it would be a good thing to see this prototype come to a release. Through social networks (i.e. someone knew someone who ...), we had Mark Shuttleworth visit our booth. Luckily, Zeng had set up his multiseat with Ubuntu and Kubuntu. Mr. Shuttleworth seemed deeply impressed. All in all we had a very good time and we hopefully able to attract many new users to VServer. Kudos go to: DerJohn for organizing the whole thing. Zeng for his zany demonstration object 'VServer Multiseat' The author of the web-interface for the demo prototype. All of those who manned or wisited the booth: Bertl, morrigan, cehteh, Gonzo, Loki|muh, cemil, BenBen, Doener, Hollow, dschingen, _are_, zeng, Milf All of those who bough trays of Jolt cola: Gonzo, _are_, Sven, Milf Gonzo for providing webcam services :) So much for this show. But as most germans will know: 'After the game is before the game', we should also look at things which can be done better next time. We were able to improvise little cards to hand out with the wiki's URL, but some fact sheets with information might have been better. Bertl provided some banners made from A4-paper (which in turn, cehteh and Milf puzzled together). But before we had those, our booth looked pale. _are_ provided his own slides to explain the combination of drbd and VServer, but apart from that, we had no cool pictures to show, so we had to explain everything in words. So to hopefully do better next time, here are some wiki topics: http://linux-vserver.org/linuxtag2006 - please add your thoughts about the show http://linux-vserver.org/Dates+and+Planning - please add any dates concerning VServer that you might know: talks, releases, tradeshows ... http://linux-vserver.org/Work+Retreat - we might want to get together and do some work and socialize. Linuxtag was great for socializing, but it just wasn't really possible to do any work. http://linux-vserver.org/VisualAids - We need pictures!

I've got an Ldap directory inside one vserver and a postfix that use ldap in another vserver. I search the best way to connect to the ldap server with the maximum of security. you can simply use the 'network' connection between them, as it will not leave the host system (it will go over the loopback lo interface, and cannot be sniffed by other guests, given that you use a secure setup which is default) use your ldap and postfix like any other network servers (forget vserver technology for a minute) and use SSL connection - ldaps:// or stunnel4 the best way is IMHO using SSL connection independent on vserver technology ... that will do also, of course trading performance for flexibility when you move the guests apart ...

It is not very good to make kernels with reduced ammount of drivers - because they will not be portable across different hardware.

[Vserver] Re: Basic Question
Thanks, its working now. But I'm not quite sure I understand the basic infrastructure of vservers. The following is taken from the Short Introduction, can someone please explain it to me: Resource sharing: Since vservers can share binaries and libraries without interfering, a second vserver generally cost 40-100 megs of disk space only. Most of this space is a copy of the packaging database. Independent updates: Vservers are updated independently even if they share binaries with other vservers. Does this mean, that as I install programs (like sshd, and other packages) on my vserver that are already installed on my host server, the binaries will be shared?
