Stai visualizzando una vecchia versione di questo article. Visualizza la versione più recente.

Installazione di base

cd /kvm
qemu-img create -f qcow2 vms/vm-centos5-i386-base.qcow2 8G
# ISO (dvd) install:
kvm -m 2047 -hda /kvm/vms/vm-centos5-i386-base.qcow2 -cdrom CentOS-5.3-i386-bin-DVD.iso -redir 'tcp:2225::22' -boot d -smp 2 -cpu qemu32,-nx -net nic,model=virtio -net user

Configurare la console seriale

(cd vms && qemu-img create -b vm-centos5-i386-base.qcow2 -f qcow2 vm-centos5-i386-serial.qcow2)
kvm -m 2047 -hda /kvm/vms/vm-centos5-i386-serial.qcow2 -cdrom CentOS-5.3-i386-bin-DVD.iso -redir 'tcp:2225::22' -boot c -smp 2 -cpu qemu32,-nx -net nic,model=virtio -net user -nographic

Aggiungere a /boot/grub/menu.lst:

serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
terminal --timeout=3 serial console

Aggiungere in menu.lst alla riga del kernel (dopo aver cancellato `quiet splash'):

console=tty0 console=ttyS0,115200n8

Aggiungere il prompt del login alla console seriale:

cat >>/etc/inittab <<END

# Console seriale
S0:2345:respawn:/sbin/agetty -h -L ttyS0 19200 vt100

Creare un account.

useradd buildbot
# Password is disabled by default in Centos5.
usermod -a -G wheel buildbot
# Decommentare la riga "%wheel        ALL=(ALL)       NOPASSWD: ALL"
# Commentare questa riga:
# Defaults    requiretty

# Mettere in public la chiave ssh per il proprio account e l'account di buildbot
# Notare che Centos5 richiede .ssh/authorized_keys chmod go-rwx.
su - buildbot
mkdir .ssh
chmod go-rwx .ssh
cat >.ssh/authorized_keys
# Paste the key, see above.
chmod go-rwx .ssh/authorized_keys
