[CentOs] Problem ze zmostkowaniem interfejsów [pusty mostek]

Witam

Chciałem zmostkować na CentOs7 wirtualny interfejs virbr0 z istniejącym enp1s2 zgodnie z opisem na [url]https://server-world.info/en/note?os=CentOS_7&p=xen[/url]  niestety po wykonaniu polecenia usuwającego fizyczny interfers i restarcie sieci następuje odcięcie dostępu przez internet na serwerze. Przerobiłem już kilka opisów włącznie z ręcznym ustawianiem parametrów tak jak tutaj [url]https://www.itzgeek.com/how-tos/mini-howtos/create-a-network-bridge-on-centos-7-rhel-7.html[/url]l interfejsów i ciągle przy końcu konfiguracji rozłącza. Szukam działającego opisu.


To wynik z obecnie funkcjonującego systemu. Niestety w wirt-managerze dostępny mam tylko  br10 z komunikatem " br10 pusty mostek"

Kod:

Chciałbym zmostkować virbr0 z enp1s2 ale przy takiej konfiguracji jak poniżej nie odpowiada 192.168.11.52

ifcfg-enp1s2

Kod:

DEVICE=enp1s2
TYPE=Ethernet
BOOTPROTO=none
ONBOOT=yes
NM_CONTROLLED=no
BRIDGE=virbr0

ifcfg-virbr0

Kod:

DEVICE=virbr0
TYPE=Bridge
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.11.52
NETMASK=255.255.255.0
GATEWAY=192.168.11.254
DNS1=192.168.11.11
USERCTL=no
