Hi,

I assume you are following Boris' installation instructions.

First Step

Bring up local Apache Server to create HTTP installation source.

# chkconfig httpd on
# service httpd start
# mount -o loop f11.iso /var/www/html/f11

To create an ISO image of your Fedora 11 Linux 64-bit DVD, run the following command:

# dd if=/dev/sr0 of=/home/user/f11.iso

OR

# dd if=/dev/hdc of=/home/user/f11.iso

OR

# dd if=/dev/cdrom of=/home/user/f11.iso

OR

# dd if=/dev/dvd of=/home/user/f11.iso

depending on which one of the above four commands work for you.

# wget http://192.168.1.36/f11/images/pxeboot/vmlinuz
# wget http://192.168.1.36/f11/images/pxeboot/initrd.img

Replace 192.168.1.36 with the IP address of your dom0.

You don't have to execute the above 2 commands.

Just copy the kernel image file vmlinux and the initial ramdisk image file initrd.img from the directory images/pxeboot on your DVD to /home/xen as indicated in your PV guest config mentioned below.

Second Step (very important)

Turn off SELinux enforcement targeted policy.

# echo 0 > /selinux/enforce

Third Step

# xm create f11.pv

Don't use virt-manager. I am not using it.

Then following the rest of Boris' instructions here:

How can delete this 20GB disk to get back the free memory? Also tell me would i need to create a disk like this for every other vm i will create or the same will be used as a virtual disk for all the guests?

The following command creates a 20 GB disk image file for you to use as virtual harddisk for your guest operating system. This operation will take some time to execute.

Run as root:
# dd if=/dev/zero of=/path/to/guest-os-hdd.img bs=1024k seek=20000 count=0
Then you use the following disk directive in your guest os configuration:

disk = [ 'file:/path/to/guest-os-hdd.img,hda,w' ]

I did this my domU starts fine but the problem occur while it needs some disk to install fedora on. PFA screen-shot of the current issue.

I didn't use virt-manager. I had it un-installed. For PV guests configuration, please see
