[edit] Server Details

The server is a Debian Lenny KVM (QEMU) within a Debian Squeeze/Sid host server.


[edit] Host Hardware

  • (8) 2GHz Processors (E5405)
  • 4 Gig RAM
  • 750G SATA (ST3750330AS)
  • (3) 30G SCSI RAID-0


[edit] Guest Hardware

Virtual, of course. :)

  • 4 CPU
  • 1 Gig RAM
  • Disk: 
$ df -h

[edit] Daemons

[edit] apache2

No modperl, modphp, etc. installed. Other than that, total stock install.


[edit] rsync

Stock Debian Lenny. 

$ cat /etc/rsyncd.conf

[repository.maemo.org]
  path = /var/www/repository.maemo.org
  comment = Extras Repositories for Maemo 5 (Fremantle)
  read only = yes
  use chroot = yes
  max connections=256
  list = yes
  uid = nobody
  gid = rsync
  dont compress = *.gz *.tgz *.zip *.z *.rpm *.deb *.iso *.bz2 *.tbz

cat /etc/default/rsync  # relevent tidbit:
RSYNC_ENABLE=true
  • I added group "rsync" as Debian doesn't come stock with a group nobody. Don't think it matters "too" much.


[edit] Guest inital setup

This is quite crude, but gives you an idea: 

After install, log in as root via VNC

apt-get install git-core
apt-get install openssh-server openssh-client

then ssh in remotely as jebba

# faster way to do this but wtf
jebba@espejo:~$ ssh localhost
jebba@espejo:~$ logout

jebba@donald:~$ scp -p .ssh/id_rsa.pub espejo.freemoe.org:.ssh/authorized_keys

jebba@donald:~$ ssh jebba@espejo.freemoe.org

topo:~$ cat /etc/.gitignore 
ld.so.cache
prelink.cache
*.swp

adjtime

setup  new drives in startup script and POWEROFF (not reboot--need to restart script to read in new drives)


sudo fdisk /dev/vdb
sudo fdisk /dev/vdc
sudo fdisk /dev/vdd

and give them one fat partition

sudo /sbin/mkfs.ext3 -j -m0 /dev/vdd1

mkdir -p /var/www/repository.maemo.org/extras /var/www/repository.maemo.org/extras-testing /var/www/repository.maemo.org/extras-devel

add them to fstab
sudo mount -a

chown them to jebba:jebba
sudo chown jebba:jebba /var/www/repository.maemo.org/extras /var/www/repository.maemo.org/extras-testing /var/www/repository.maemo.org/extras-deveel

rsync over from topo what you already downloaded:
rsync -ault --rsh=ssh /HUGE/mirrors/repository.maemo.org/ espejo.freemoe.org:/var/www/repository.maemo.org/


sudo apt-get install reprepro

add rsyncd conf
turn of fucking portmap ? why that starting.
sudo /usr/sbin/update-rc.d -f portmap remove
sudo /usr/sbin/update-rc.d -f mountnfs.sh remove
sudo /usr/sbin/update-rc.d -f mountnfs-bootclean.sh remove
sudo /usr/sbin/update-rc.d -f x11-common remove


turn on rsyncd

set up vsftpd

sudo apt-get install reprepro gpgsm inoticoming

 reprepro -vv --basedir=/var/www/repository.maemo.org/


[edit] Host Server

[edit] Initial setup

  • Latest kernel with virtio etc. (Include relevant kernel .config).
  • Create disk images:

Example: 

qemu-img create -f qcow2 -o cluster_size=2097152,preallocation=metadata /HUGE/kvm/espejo/espejo-FOO.qcow2 50G


[edit] Daily Use

  • Start kvm on boot via good ol' rc.local: 
/usr/local/bin/kvm-start-espejo >> /tmp/espejo-kvm-err 2>&1 &

Startup script: 

$ cat /usr/local/bin/kvm-start-espejo 
#!/bin/sh

/usr/local/bin/qemu-system-x86_64 \
       -drive \
        file=/HUGE/kvm/espejo/espejo.qcow2,index=0,if=virtio,cache=writeback,boot=on \
       -drive \
        file=/HUGE/kvm/espejo/espejo-extras.qcow2,index=1,if=virtio,cache=writeback \
       -drive \
        file=/HUGE/kvm/espejo/espejo-extras-testing.qcow2,index=2,if=virtio,cache=writeback \
       -drive \
        file=/HUGE/kvm/espejo/espejo-extras-devel.qcow2,index=3,if=virtio,cache=writeback \
       -drive \
        file=/HUGE/kvm/espejo/espejo-pool.qcow2,index=4,if=virtio,cache=writeback \
       -drive \
        file=/HUGE/kvm/espejo/espejo-maemo.qcow2,index=5,if=virtio,cache=writeback \
       -cpu kvm64 \
       -m 1024 \
       -vnc :6 \
       -daemonize \
       -enable-kvm \
       -name espejo \
       -net nic,vlan=0,model=virtio \
       -net user,hostfwd=tcp:63.247.92.156:22-:22,hostfwd=tcp:63.247.92.156:80-:80,hostfwd=tcp:63.247.92.156:873-:873,hostfwd=tcp:63.247.92.156:20-:20,hostfwd=tcp:63.247.92.156:21-:21 \
       -smp 4 \
       -runas jebba &

[edit] TODO

  • Could set up separate partitions for /tmp and such, but probably not worth it.
  • Build latest/greatest kernel on guest to take advantage of latest virtio code to improve disk performance.
  • Set up puppet for configs (worthwhile?).
