CentOS 5.3

[tontod]

I just got CentOS 5.3 up and running

Any recommendations? This is a new machine too - quad core 3.0 Ghz, 8 GB RAM. Any kind of benchmarks I should run?

I'm going to get VirtualBox and install XP as a VM. How much disk space/RAM should I allocate for that?

I got this error trying to download/install virtualbox:

/tmp/VirtualBox-2.2.2_46594_rhel5-1.x86_64.rmp could not be opened, because the associated helper application does not exist. Change the association in your preferences. I'm not sure how to do that?

That should be rpm, so unless that is a typo on your part, that's your problem.

It might have been a typo. I was able to actually install it using yum, but I cant create a VM, I get this error trying to execute /etc.init.d/vboxdrv setup

[root@tonto init.d]# ./vboxdrv setup

Any help would be appreciated, thanks!

You need to install the kernel source.

 

[tontod]

Thanks, it installed fine, but same error, guess I'll try rebooting.

I found the issue - 2.6.18-128.1.6.el5.x86_64 vs. 2.6.18-128.el5, I created a symlink, works now, I get further, but now this:

/etc/init.d/vboxdrv setup
Stopping VirtualBox kernel module [ OK ]
Recompiling VirtualBox kernel module [ OK ]
Starting VirtualBox kernel module [FAILED]
(Cannot create device /dev/vboxdrv with major 10 and minor 62)

Are you sure you downloaded the correct rpm? It looks like you have the i686 kernel installed (32bit) and are attempting to install the x86_64 (64bit) virtualbox package. What is the output of uname -r?

 

[tontod]

Sweeet, tried it again, works!!!!!!

/etc/init.d/vboxdrv setup
Stopping VirtualBox kernel module [ OK ]
Removing old VirtualBox netflt kernel module [ OK ]
Removing old VirtualBox kernel module [ OK ]
Recompiling VirtualBox kernel module [ OK ]

Thanks!!

uname -r
2.6.18-128.el5

From the link you gave me, I installed this one:

kernel-devel (both 32- & 64-bit architectures)

Glad you got it. Now for your question:

Unless you really need more, 1GB RAM should be plenty.

Ok, off and running XP in a VM. How do you make the VM fill the entire screen, if I maximize it, the VM window is small and surrounded by white/greyspace instead of actually filling up the screen.

Not sure but f11 is often the toggle-fullscreen key for many applications.

Got it, had to install guest additions from the Devices Menu.

Yup... There is a pretty active forum on their site too.

I generally just RDP into my Windows guests. Having a full screen guest on a second monitor is great.
