4.6 Creating a Paravirtualized Guest Manually

To manually create a paravirtualized guest:

1.Create the root file system

2.Populate the root file system

3.Configure the guest

4.6.1Creating the Root File System

To create the root file system:

1.Create a root partition for the guest. The root partition may be a:

■Physical partition

■Logical Volume Manager-backed Virtual Block Device

■File-backed Virtual Block Device

Select one of the following options to create the root file system.

a.Using a physical disk partition

Create a disk partition for the guest root. Make a file system on the partition.

b.Using a Logical Volume Manager-backed Virtual Block Device

A particularly appealing solution is to use a Logical Volume Manager (LVM) volume as backing for a guest file system, as this allows dynamic growing and shrinking of volumes, as well as snapshots, and other features.

To initialize a partition to support LVM volumes, enter

# pvcreate /dev/sda10

Create a volume group named vg on the physical partition:

# vgcreate vg /dev/sda10

Create a logical volume of 4 Gigabytes named myvmdisk1:

# lvcreate -L4096M -n myvmdisk1 vg

You now have a /dev/vg/myvmdisk1. Make a file system on the partition:

#mkfs -t ext3 /dev/vg/myvmdisk1

c.Using a file-backed Virtual Block Device

To create a 4 Gigabyte file-backed virtual block device, enter

#dd if=/dev/zero of=vm1disk bs=1k seek=4096k count=1

Make a file system in the disk file:

#mkfs -t ext3 vm1disk

The tool requests that you confirm the creation of the file system. Enter y to confirm the creation of the file system.
