Instalacja i konfiguracja hosta KVM z libvirt i Open vSwitch na Ubuntu 14.04 Trusty Tahr. Poni\u017csze kroki najlepiej wykona\u0107 zaraz po zainstalowaniu systemu operacyjnego.<\/p>\n

1) Instalujemy wymagane pakiety:<\/p>\n

root#server:\/# apt-get install openvswitch-switch qemu-kvm libvirt-bin<\/strong><\/pre>\n
2) Usuwamy domy\u015blny bridge i tworzymy bridge oparte na Open vSwitch:<\/p>\n
<\/p>\n
root#server:\/# virsh net-destroy default<\/strong><\/pre>\n
root#server:\/# ovs-vsctl add-br ovsbr0\r\n<\/strong>root#server:\/# ovs-vsctl add-br ovsbr1<\/strong><\/pre>\n
W katalogu \/etc\/libvirt\/qemu\/network<\/span> tworzymy 2 pliki konfiguracyjne:<\/p>\n
root#server:\/# touch .\/ovsbr0.xml\r\n<\/strong>root#server:\/# touch .\/ovsbr1.xml<\/strong><\/pre>\n
i wklejamy do nich poni\u017csze konfiguracje, do ovsbr0.xml:<\/p>\n
<network>\r\n<name>ovsbr0<\/name>\r\n<forward mode='bridge'\/>\r\n<bridge name='ovsbr0'\/>\r\n<virtualport type='openvswitch'\/>\r\n<\/network><\/pre>\n
do ovsbr1.xml:<\/p>\n
<network>\r\n<name>ovsbr1<\/name>\r\n<forward mode='bridge'\/>\r\n<bridge name='ovsbr1'\/>\r\n<virtualport type='openvswitch'\/>\r\n<\/network><\/pre>\n
Po zapisaniu plik\u00f3w tworzymy oba bridge w oparciu o powy\u017csz\u0105 konfiguracj\u0119:<\/p>\n
root#server:\/# virsh net-define ovsbr0.xml<\/strong>\r\nroot#server:\/# virsh net-define ovsbr1.xml<\/strong><\/pre>\n
3) Docelowo usuwamy konfiguracj\u0119 poprzedniego bridga i ustawiamy automatyczny start nowo skonfigurowanych mostk\u00f3w:<\/p>\n
root#server:\/# virsh net-undefine default\r\n<\/strong>root#server:\/# virsh net-autostart ovsbr0\r\n<\/strong>root#server:\/# virsh net-autostart ovsbr1<\/strong><\/pre>\n
4) Ustawiamy konfiguracj\u0119 sieci dla obu mostk\u00f3w w pliku \/etc\/network\/interfaces<\/span>, poprzez dodanie odpowiednich wpis\u00f3w identycznie jak w przypadku standardowych interfejs\u00f3w:<\/p>\n
auto ovsbr0\r\niface ovsbr0 inet static\r\n   address 192.168.10.1\r\n   network 192.168.10.0\r\n   netmask 255.255.255.0\r\n   broadcast 192.168.10.255\r\n\r\nauto ovsbr1\r\niface ovsbr1 inet static\r\n   address 192.168.20.1\r\n   network 192.168.20.0\r\n   netmask 255.255.255.0\r\n   broadcast 192.168.20.255\r\n<\/pre>\n
Mo\u017cemy te\u017c ustawi\u0107 konfiguracj\u0119 dla ipv6:<\/p>\n
iface ovsbr0 inet6 static\r\naddress 2001:xxxx:xxxx:1::1 netmask 64<\/pre>\n
5) Dodajemy fizyczne interfejsy do bridga:<\/p>\n
root#server:\/# ovs-vsctl add-port ovsbr0 eth0<\/strong>\r\nroot#server:\/# ovs-vsctl add-port ovsbr1 eth1<\/strong><\/pre>\n
6) Uruchamiamy ponownie komputer i sprawdzamy czy oba mostki zosta\u0142y uruchomione:<\/p>\n

Przydatne polecenia do testowania:<\/p>\n<\/div>\n
