Create a Host and 4 VM Guests using XEN (not Virtual Box):
a. The Host:
i. CentOS Linux
ii. Network address should be: 1.0.0.1
iii. SSH and VNC should be enabled
iv. Should be the Gateway to the Internet in both directions for the Guests – so, you shouldn’t be able to access the guests using SSH or VNC directly, you have to access them through the Host only.
b. The Guests:
i. RedHat Linux.
ii. Network address should be: 10.0.0.1
iii. SSH and VNC should be enabled
iv. Two Guests should be installed using Para Technique, and two should use the Full Virtualization technique
v. We need to be able to use HHD for two of them, and LVM for the other two
vi. Install Apache Web Server on one of the guests – we should be able to access the web server from outside

plz. some one help me i can do this as a concept :)

i think. i can do that. OK, I am absolutely new to setting up a virtual machine. I used the command below and received an error that I have no idea what it means:

Paravirtualized guests cannot install off cdrom media.

virt-install \
> –name Fedora-12 \
> –ram 1000 \
> –file /data/vm/Fedora-12 \
> –network network:default \

I am having the same trouble as Kartil Vashishta, my vm manager does not allow me to install via CD/DVD, this is right after an install of centos in text mode then switching over to gui (because of an intel gma problem) just though I would add that although I don’t think that is what is causing it, also I am using the newest release 5.4 I think.

Hi, Im running a centos 5 64bit +cpanel with about 15 hosting accounts running in it. There are few of them wanted windows hosting to run asp vb and etc. So i cant get a dedi or vps just for 2 or 3 accounts, so i have heard about using xen to run multiple vps on it, my questions are :

1) can i install xen to run windows without interupting cpanel and other hosting accounts?

2)Can i do all these installation from command prompt? how about windows OS? without CD?

Thanks

The option to install the virtual host via CD/DVD is grayed out for me, the only options I have is to install via the internet. Did I miss some step to add the dvd drive to the virtual machine. Please help.

it is a fantastic tutorial!!!!!!!! right to the point!

i wound suggest to include a note to edit the /etc/grub.conf and change the ‘default=0′ or it will start the old kernel.

cheers!

Nice howto. Maybe not very thorough but gives an idea what to look for ( for noobs like me :)

wrt professionals with no gui… go read the source hackers ;p

Vivek, Can you please add stuff like:
Installation of XEN on non GUI system (with virt-console may be….)
How to create a VM and change resources .. etc…

Would be helpful ……….

Thanks in Adv!

this is a really poor and incomplete guide.

first of all, it only works for those lucky few who get to use a graphical interface. professionals in the field, who must conserve resources and minimize infrastructure, have absolutely no use for virt-manager.

second… there simply has to be more to it.

What would have been helpful is if you had:
a) included more information than “follow on screen instructions” such as a idea what sort of information we should be putting in a particular field. For example, if I wanted to install ubuntu-server, what would the URL be?
b) Included the instructions for installing off local media – as far as I know, you can’t install directly off dvd or cd but can off nfs so if you export the cd/dvd via nfs and then use the url for the nfs share you’d be sweet.

Scott,

I’m sorry to hear it didn’t work out for you. These instructions are only tested on CentOS 5.0 and Fedora 7. I’ve already mentioned the fact.

“Now just follow on screen instructions to setup new guest operating systems (VPS oses). ”

You’re kidding, right? How unfortunate this topic got indexed in Google, because here’s what gets glossed over:

Try installing a VM from a regular DVD. Go ahead. Please.

Under Install Media URL, I’ve tried
/media/Fedora 8 x86_64 DVD
/media/Fedora8 (which I ln -s to ‘Fredora 8 x86_64 DVD’)
file:///media/Fedora8
/dev/scd0 (the DVD device)

/dev/scd0 does spin the drive, but then vaguely complains it can not find what it needs…

It appears you

OK, pop in a Fedora 8 DVD
