• hack /usr/local/scripts/netfilter/local/chains/vms/kvm_0231_chain.sh on host to allow gateway conns
• first hd is /dev/vda
• default gentoo handbook install with lvm setup on vda3 and one large lv_root
• install lvm2 so you can build a lvm initramfs
  • if you skip this you will have tons of fun loading lvm in the initramfs shell: lvm vgscan --mknodes && lvm lvchange -a ly vg01/lv_root
• kernel build with: genkernel --install --lvm --menuconfig all (do not use --virtio, activate them in menuconfig instead, I had heaps of fun hunting down all the modules)
  • actually genkernel --install --lvm --kernel-config=/root/kernel.config all since lazy me hates using a ui
  • the --virtio switch seems screwed due to some oldconfig changes with the VIRTIO_MMIO system, but i haven't looked into that more
• remember to also set GRUB_CMDLINE_LINUX="dolvm" in /etc/default/grub (as i said before, a ton of fun)
• more things to install on new machines: emerge dev-vcs/git vim
• now for puppet: USE="augeas vim-syntax" emerge puppet
• before using puppet: emerge eix && eix-update
• clone puppet tree: git clone https://github.com/purplehazech/purplehazech-orcatamer.git /etc/puppet/environments/development
• install librarian: gem19 install librarian-puppet
• load puppet modules: cd /etc/puppet/environments/development && librarian-puppet install
• workaround some TODOs: ln -s /etc/puppet/environments/development/ /vagrant && mkdir /usr/local/portage && touch /usr/local/portage/make.conf && ulimit -n 2048 && emerge sudo && emerge dev-ruby/rgen --autounmask-write && dispatch-conf && emerge dev-ruby/rgen
• test if puppet is useable: puppet apply --environment=development --modulepath=/etc/puppet/environments/development/modules/:/etc/puppet/environments/development/manifests/ -e 'notify{"test":}' --pluginsync
• run puppet like so to find the first batch of stuff to fix: puppet apply --environment=development --modulepath=/etc/puppet/environments/development/modules/:/etc/puppet/environments/development/manifests/ -e 'include ::role::puppet::master' --pluginsync --noop
• let puppet rip: puppet apply --environment=development --modulepath=/etc/puppet/environments/development/modules/:/etc/puppet/environments/development/manifests/ -e 'include ::role::puppet::master' --pluginsync
• after running the last command until all the errors where fixed i can try to run in agent mode: puppet agent --test --server=`hostname -f`
  • i still need to figure out why the --server flag is needed at this stage, somehow the agent is consulting DNS rather than /etc/hosts

now for some hacking that i did to test some concepts:

• setup openldap tooling: emerge openldap
• search for machine: ldapsearch -D 'cn=Manager,dc=stoney-cloud,dc=org' -w admin '(&(objectClass=sstVirtualizationVirtualMachine)(sstNetworkHostname=kvm-0231))'
• open ldap port in fw: ldap_pub_out="10.1.130.13" and openTcpPortOut "${chains_out[pub]}" "$ldap_pub_out" "636"
  • i also need to configure ldaps_int_in="${ip_int[vm-test-02]} ${ip_int[vm-test-03]} 192.168.140.136" in /usr/local/scripts/netfilter/local/chains/vm-test-01/vm-test-01_chain.sh for the above to work.

TODOs

• replace silly headers in orcatamer with block chars with something that most tools dont bork on (ie. some ascii art)
  • I removed this on Puppetfile and Modulefile to get librarian to run
• use github https URLs through out, they are simply proxy friendlier everywhere
• refactor role and profile things into proper modules and use proper puppet:// data urls
• dont' depend on /usr/local/portage/make.conf
• figure out why the betagarden overlay needs ulimit -n 2048 to clone
• figure out why layman-add from betagarden needs sudo
• install rgen for puppet parser future at some sensible part of bootstrapping
• figure out what going on here: Feb 22 22:30:01 vm-test-01 ulogd[30493]: p_kvm-0231_0_in Denied dst:: IN=vmbr0 OUT=vmbr0 MAC=01:00:5e:00:00:12:00:00:5e:00:01:03:08:00 SRC=192.168.140.2 DST=224.0.0.18 LEN=56 TOS=10 PREC=0x00 TTL=255 ID=33458 DF PROTO=112 MARK=0
