Xen / KVM CentOS-5 How To Document
by gene.poole＠macys.com 16 Jul '10

16 Jul '10

Does anyone have any idea where I can locate a 'GOOD' how-to document on implementing Xen and/or KVM on a CentOS-5.3 system? I'm currently running VMware Server 2.0.2, but I would like to make the move to the open source virtualization - if possible. What I found is somewhat short on the networking piece. It doesn't matter if it's TUI or GUI. Thanks, Gene Poole gene.poole(a)macys.com

Error message downloading latest Spamassassin data files via sa-update
by Gilbert Sebenste 16 Jul '10

16 Jul '10

Hello everyone, When I type "sa-update" to get the latest files for Spamassassin, I see this error: ]# sa-update Argument "1.39_01" isn't numeric in subroutine entry at /usr/bin/sa-update line 83. My Google-fu came up with nothing when searching for this error. Am I the only one getting this to happen, or are any of you seeing it as well?

Subject=Re:CentOS Simple solution for small network in school
by Paul Schoonderwoerd 16 Jul '10

16 Jul '10

Hello, I would use some (old) pc's as thin clients and have them boot over the network from the server, or from cd. Then, have them make a connection to the server with the NX protocol. Thinstation.org provides all this. Just install FreeNX on the server (yum install) and manage the accounts as local accounts. Can't have it any simpeler than that in my opinion, also for management.

Disks for virtualization
by David Dyer-Bennet 16 Jul '10

16 Jul '10

I'm not looking to move virtual machines between physical platforms; just want some protection between applications sharing a physical server. They'll all be using local disk in one form or another. Much the easiest to manage is just having the virtual machine use a file in dom0 as its disk. Without pre-allocating, this lets me over-commit somewhat to cover unknown future needs, for example. The alternative seems to be LVM partitions. Those are easy to throw around too, but after enough creation / destruction you can end up with your free-space fragmented so you can't use it, right? But I imagine there's a performance benefit to LVM partitions over dom0 files. For things like foswiki for internal use by a development team, and Nagios monitoring for about a dozen systems, do i need that extra performance? Does anybody have a rule-of-thumb for the difference? -- David Dyer-Bennet, dd-b(a)dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info

Problems getting my wireles connection to work

I have an Everex laptop (ick, but it was super cheap) that has an Atheros wireless NIC in it, but I can't seem to get it to connect to my wireless in-home LAN.

DomU install failure for Centos 5.5 using the "RHEL 5.4 and greater" OS option
by David Dyer-Bennet 15 Jul '10

15 Jul '10

Had some trouble getting Centos x64 installed as a guest in my new Centos 5.5 x64 server using Xen (thanks again for all the help getting the hardware virtualization turned on and confirmed yesterday!). When I chose OS Linux, and whatever they called the detailed OS subtype I chose the Red Hat Enterprise 5.4 and greater, and then tried to install Centos 5.5, the install started and I got into the graphics installer, but when it was supposed to start installing individual packages the whole virt-manager and console window hung. Three times, at that same point. (I was monitoring web traffic to the install files it was working from, and it wasn't fetching files, either). When I selected just "RHEL 5", it installed (and I'm now running the package updater, and it may have hung there; we'll see). I would have expected the rhel 5.4 and greater option to be the right one for Centos 5.5. Anybody have similar experiences? Or, even more interesting, contrary experiences? -- David Dyer-Bennet, dd-b(a)dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info
