Birdlab je hypervisor, který vytváří on-demand testovací prostředí pro Birda.
Podle definičního souboru vytvoří a spustí sadu virtuálních strojů, spojí je do
sítí podle definice a nastaví příslušným rozhraním IP adresy.
Celé prostředí sídlí v ROOT=/var/lib/virt, definice prostředí v $ROOT/etc/virtlist.
S ohledem na malý počet členů týmu návrh systému neřeší kolize mezi jednotlivými uživateli.

####################### Konec konfigurace ###########################
Manipulaci s virtuály zajišťuje příkaz vctl.
vctl prepare: vytvoř potřebná rozhraní, spusť potřebné daemony
vctl status: vypiš stav všech virtuálů
vctl cleanup: zruš rozhraní a vypni daemony, ukliď po sobě; nevypíná virtuály
vctl start <host> [args...]: nastartuj virtuál <host>; argumenty navíc se předají přímo Qemu.
vctl ssh <host>: připoj se na terminál <host>ovi
vctl mon <host>: otevři monitorovací socket Qemu
vctl stop <host>: vypni virtuál <host>; pokouší se o to několika způsoby, poslední je sigkill.
Virtuály běží v Qemu a jejich síťová rozhraní jsou připojená do openVswitche
(s tím se dá povídat přes ovs-vsctl, základní příkaz je ovs-vsctl show).
Linky a sítě jsou vytvořené jako jednotlivé VLANy v OVS, tag se generuje hashovací funkcí z definice sítě.
Každý virtuál má k dispozici /mnt/nfs, kam se namontuje $ROOT/nfs. Při startu se spustí /mnt/nfs/rc.local.
V základu se tímto skriptem nastaví sítě. Adresář $ROOT/nfs/net obsahuje další
důležité soubory definující nastavení sítě v závislosti na MAC adrese
virtuálního rozhraní.
Je-li tedy třeba po startu také přeložit Birda a spustit jej se správným
configem, $ROOT/nfs/rc.local je správné místo pro zavolání takové věci.
