KVM : install CentOS 5.6 as a guest with kicksart

KVM host

# tail -1 /etc/lsb-release DISTRIB_DESCRIPTION="Ubuntu 11.04" # uname -r 2.6.38-10-server

[ preparation ]

- kickstart file
- ISO image
- httpd

I used the following kickstart file.

# cat centos5-6-kvm-ks.cfg #platform=x86, AMD64, or Intel EM64T # System authorization information auth  --useshadow  --enablemd5 # System bootloader configuration bootloader --append="console=ttyS0,115200n8 console=tty0" --location=mbr # Partition clearing information clearpart --all --initlabel # Use text mode install text # Firewall configuration firewall --disabled # Run the Setup Agent on first boot firstboot --disable # System keyboard keyboard jp106 # System language lang ja_JP # Installation logging level logging --level=info # Use network installation url --url=http://192.168.10.15/centos # Network information network --bootproto=static --device=eth0 --gateway=192.168.10.254 --ip=192.168.10.161 --nameserver=192.168.10.15 --netmask=255.255.255.0 --onboot=on # Reboot after installation reboot #Root password rootpw --iscrypted $1$o4BvPEzq$CmfSLIJLfURGbGrLlTnOc1 # SELinux configuration selinux --disabled # Do not configure the X Window System skipx # System timezone timezone --isUtc Asia/Tokyo # Install OS instead of upgrade install # Disk partitioning information part / --bytes-per-inode=4096 --fstype="ext3" --size=5000 part swap --bytes-per-inode=4096 --fstype="swap" --size=512 %packages @development-libs @development-tools @editors

When specifying kickstart file with virt-install , you need to specify http://xxx.
So you need to prepare httpd.
I prepared both CentOS ISO and httpd on the KVM host.

mount ISO image

# mkdir /var/www/centos # mount -t iso9660 -o loop /var/disk1/ISOs/CentOS-5.6-x86_64-bin-DVD-1of2.iso /var/www/centos

start httpd and copy ks file under http document root. ( in my case , /var/www )

# apache2ctl start # cp centos5-6-kvm-ks.cfg /var/www/

confirm you can get ks file.

# wget http://192.168.10.15/centos5-6-kvm-ks.cfg

[ install CentOS 5.6 as a guest VM with virt-install ]

install kvm-pxe if you have not installed.

# apt-get install kvm-pxe # dpkg -L kvm-pxe /. /usr /usr/share /usr/share/qemu /usr/share/qemu/pxe-rtl8139.bin /usr/share/qemu/pxe-pcnet.bin /usr/share/qemu/pxe-virtio.bin /usr/share/qemu/pxe-ne2k_pci.bin /usr/share/qemu/pxe-e1000.bin /usr/share/doc /usr/share/doc/kvm-pxe /usr/share/doc/kvm-pxe/copyright /usr/share/doc/kvm-pxe/changelog.Debian.gz

build a VM

# virt-install --connect qemu:///system -n centos5-1 -r 512 –dis k path=/var/disk1/centos5.5-1.img,size=6 --vcpus=1 --os-type linux --os-variant rhel5.4 --nographics --location http://192.168.10.15/centos --extra-args='ks=htt p://192.168.10.15/centos5-6-kvm-ks.cfg ksdevice=eth0 console=tty0 console=ttyS0, 115200n8' --keymap ja --network bridge=br0 –nographics

the installation has been processed automatically.
