Centos deployment problems on KVM
 

Hi,

I'm trying to create a VM from Centos ISO file.
I've created successfully an interactive Centos 7. But when i tried creating a centos with kickstart file I've encountered some problems

This is what I ran:

1. qemu-img create -f qcow2 /opt/disk3.qcow2 20G

2. virt-install --virt-type kvm --name allotOS --ram 4096 --cdrom=/opt/OS.iso --disk /opt/disk3.qcow2,format=qcow2 --network network=default --graphics vnc,listen=0.0.0.0 --noautoconsole --os-type=linux --os-variant=rhel6

3.This is my kickstart file (just the beginning)

install
# Use DVD installation media
cdrom
lang en_US.UTF-8
#System keyboard
keyboard us
#System timezone
timezone --utc GMT

network --onboot yes --device eth0 --bootproto static --ip 11.11.11.11 --netmask 255.255.0.0 --noipv6 --gateway 11.11.0.1 --nameserver 198.168.254.2

#Root password
rootpw --iscrypted $1$R.alKkPn$kzGDYBkJKb3Tc2OcjSFu7.
#Initial user
#user --name=admin --iscrypted --password=Ce455MjL5TAqc
firewall --disabled
authconfig --enableshadow --enablemd5
selinux --disabled

bootloader --location=mbr --append="crashkernel=auto transparent_hugepage=never rhgb quiet" --driveorder=vda
#************PARTITIONING *************************
zerombr
## ignoredisk --only-use=vda
clearpart --drives=vda --all --initlabel
part / --fstype ext4 --size=20000 --asprimary --ondisk=vda
#part swap --size=8192
%include /tmp/swappart
part /opt --fstype ext4 --size=100 --grow --asprimary --ondisk=vda
#Reboot after installation
reboot --eject
#Use text mode install
#text



4. the error i recieve is: "Boot failed: Couldnt read from CDROM (codde0004)

Any advice?

Thx

A few steps that I would have tried:

Can you connect that ISO file to another virtual machine and access it from there?

And when does the error occur - before syslinux starts or after?
Are there any other messages, error or not, before "boot failed"?

I also wonder if SELinux could be involved. If your VM host has SELinux, set it to permissive.

Centos 7 now allows checking a kickstart file with the ksvalidator program (yum install pykickstart). Tried it?

it should NOT be a SE issue on the cent host

installing the KVM from yum will have set the CORRECT SE context



cent7 iso is NOT called "OS.iso"

please use the REAL name
"CentOS-7-x86_64-DVD-1503-01.iso"
or
"CentOS-7-x86_64-Everything-1503-01.iso"

Issue resolved
 

The problem was with the ISO file.
The only change made to the original ISO is the change of disks.
In original (for physical disks) the disk is sda. For virtual the disk is vda
