OK, this is the perfect sequay for me :-) Assuming you only want Linux, and at that CentOS Linux - which are both the case for me - what Config Management system would you use? What is out there? A few months ago I sort of had a similar thread going and got the following : Slackmaster - looks like this is from google chef - have not looked it up yet puppet - got a test bed going and just bought the book because have not found much on line in terms of complex configs and how to actually use it to manage your environments bcfg2 - have not looked for it yet CF Engine - am vaguely familiar with it. thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

Virtualization - what do You recommend?
by Rafał Radecki 06 Feb '10

06 Feb '10

Hi All. I plan to use virtualization in my production environment. I plan to use one of the following options: - KVM; - VMWare Esxi; - VMWare Workstation. I plan to install Windows 2008 as a guest. I want to use something like LVM snapshots for backups. Stability is also very important, the guest will be used as a production server. Which option could You recommend and why? Thank You very much in advance :) With regards, R.

gdm-simple-greeter, redux
by m.roth＠5-cent.us 06 Feb '10

Does *anyone* have a clue where gdm-simple-greeter stores the usernames it presents? I know that it is not getting it out of /etc/passwd. based on users who can log in, since I have several machines where one user, who's rolled off, is still showing, even though /etc/passwd has him as having a shell that doesn't exist. mark

Using XEN to install Windows XP as guest on CentOS 5 as host ?
by Hadi Motamedi 06 Feb '10

06 Feb '10

Dear All I want to use XEN to install Windows XP as guest on CentOS 5 as host . I tried as the followings : #yum install xen virt-manager kernel-xen #chkconfig xend on #reboot Then I booted my CentOS server using XEN kernel . I tried as the followings : #virt-manager & But when continuing to create the virtual machine , under Installation Method menu , I cannot select 'local install media (cdrom)' and just the Network install tree is highlighted . So I tried to reach the desired one , by issuing as the followings : #virt-install --paravirt --name WindowsXP --ram 128 --file /vm --location /mnt/cdrom But it didn't get through as well . Can you please let me know how can I do it correctly ? Thank you Hotmail: Trusted email with powerful SPAM protection.

XEN
by Matt 06 Feb '10

06 Feb '10

I have a fairly high disk i/o intensive email server I am thinking of upgrading. I was thinking of upgrading it to CentOS 5.x 64bit. I was also thinking of running it as a guest under XEN. Would this allow me to more easilly transfer it to faster hardware in the future? Or would running as a guest seriously hurt disk i/o?

VMWare ESXi & CentOS5.4
by Thom Paine 05 Feb '10

05 Feb '10

I have a brand new Dell Poweredge T310 server with 4G ram and 1TB raid-5 hard drive in it. I Really only need to be able to run a copy of CentOS 5.4 on it, but I'm wondering if in the build process should I stick on ESXi 4 and then run CentOS as a vm? This would give me the options to roll out other VM's if I want over the life of the server (which I likely won't need) but the convenience of having them might be there. I'm only thinking of doing this because ESXi is free, and won't add any cost to this server. This server is going to be a domain controller for 5 workstations which will run Windows XP, as well as host 1 website with email. It will setup a few shares for samba, and have one network printer attached to it. Any thoughts to this, or should I just put on CentOS 5.4 and be done with it? I know it's like asking what everyone's favourite colour is, but maybe a few replies will give me some ideas. Thanks. -- -=/>Thom
