There was a build on koji for Fedora 21 but nothing for centos in over a year. There are problems in the build due to a large number of dropped packages. I've been working with the virtualization tool in centos and ovirt in particular. There are good reasons to look at it as a replacement for ltsp. It greatly separates the user environment and the spice client makes the remote session feel local. There's much work to be done to make it as good for school use as k12ltsp has been. There will still need to be a pxeboot setup and the base install on the clients will need to be modified to connect to a remote vm.

With cloned vm and memory ballooning it's no more disk little more ram use than ltsp and can scale across multiple servers. It also totally isolates each user vm from others. So a fork bomb only crashes one vm and not all thin clients. Middle school found out how to do that. Fixing it in ltsp was a challenge. In vm, it's only their problem. Or have you done it in a > multiuser X environment too? Used ltsp in Atlanta for 7 school build out of 2000 clients on 33 servers in 2006-2007. That hard coded clients to a server. It that server was down, all computer use stopped. With the ovirt process, the VMs can run on a different server automatically until the down server is restored and clients migrated live.

I was hoping maybe this had been resolved by now. It appears lightdm will not build on centos 6 client chroot.I was going to give this a try, to do away with ldm but no joy. it requires the systemd piece which Ubuntu, Debian has. I simply cannot figure out what the ldm,or ssh is not able to decypher users located on server? A while back i did setup authorized_keys for root on server,,,a standard user could get a successful login on a thin client,but once logged in the user is now root. No good. :( Note. I never did try doing the nbd setup. possibly this may work? I've never had to use this before.

Thanks, Barry _______________________________________________ K12OSN mailing list K12OSN at redhat.com https://www.redhat.com/mailman/listinfo/k12osn For more info see Johan, ## For the following to work you need an existing, running, working LTSP/CentOS 6.x server. Prerequisite: 1) On new CentOS 7 server install the ltsp-5.repos rpm same as you do for CentOS 6 server and "yum -y install ltsp-server" this of course install the server peices for ltsp workings. 2) No need to do the client insall. 3) You will need to setup your dhcp server after this of course and enable tftp server and copt exports same as centOS 6. To get a working LTSP setup on CentOS 7, you can simply rsync the /var/lib/tftpboot & /opt/ltsp directories from your working ltsp server to your new CentOS 7 server. rsync -avz /var/lib/tftpboot newserver:/var/lib/ rsync -avz /opt/ltsp newserver:/opt/ It's really that simple.. usb sticks, sound works. This is a pretty rough way of making things work,,but it does work. Hopefully someone will debug what is killing the ldm logins currently on an CentOS install of ltsp...:( Take Care, Barry
