1. virt-builder (pokud jiz neni predpripraveny)

pokud jiz je, tak jen “cp debian-9_<heslo>.img ../images/nazev_zakaznika.img

1. virt-intall –ram xxxx –vcpu yyyy podle objednavky
2. koupit verejnou ip adresu - zmenit MAC a uvnit vps /etc/network/interfaces
3. pripadne zaradit do xenbr40 a pridelit 10.0.40.xx
4. zmenit vnc na verenou IP a port 59000 + posledni cislo IP napr. 59020
5. hotovo :)

virt-builder debian-9 --size=6G --format qcow2 -o /var/lib/libvirt/images/debian9-XXXX.raw --hostname XXXX --network --timezone Europe/Prague

Typicky vystup vypada takto pozor je zde heslo, vystup docasne uchovat

kdyz mam ip od hetzner dam request separate mac address ve virsh edit mac address pastecertus

• odstranit image compression radek

 * ipaddr je adresa hlavniho serveru napr. 88.198.64.144

pripojim se pak pres virsh console nebo vncviewer
