Vytvareni virtual serveru KVM

virt-builder (pokud jiz neni predpripraveny)

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

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

virt-builder debian-9 --size=6G --format qcow2 -o /vps/debian9-XXXX.qcow2 \
   --hostname XXXX \
   --network \
   --timezone Europe/Prague \
   --firstboot-command "dpkg-reconfigure openssh-server"

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

Verejna IP

IP koupit na hetzneru (ikonka je spatne videt a je v sekci servers → vyber serveru → v pravo dole)
musi byt v xenbr10
musi se nechat vygenerovat nova MAC adresa
server nutne vypnout a zapnout, reboot nenacte novy hw

  <interface type='bridge'>
      <mac address='00:50:56:0c:a5:80'/>
      <source bridge='xenbr10'/>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
    </interface>

Zvetseni image

qemu-img resize tzdebian.img +10G

<graphics type='vnc' port='*' autoport='no' listen='ipdpddr' passwd='x'>
<listen type='address' address='ipaddr'>

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

   <graphics type='vnc' port='*' autoport='no' listen='ipdpddr' passwd='x'>
   <listen type='address' address='ipaddr'>

odstranit image compression radek

* ipaddr je adresa hlavniho serveru napr. 88.198.64.144

pripojim se pak pres virsh console nebo vncviewer

   vncviewer 88.198.64.144:59181

musim na novem terminalu, ne kdyz jsem prihlasen na nemeckem serveru
