tap et virtualBox

neowdj

bonjour à tous,

j'ai voulu créer un pont reseaux (pour virtualbox) (eth0 et tap0) en suivant ce tuto

http://forums.fedora-fr.org/viewtopic.php?id=25865

ayant besoint d'un autre pont reseaux pour ma 2 second machine virtuel j'ai installé une 2emme carte reseaux (eth1) et j'ai repris le tuto en modifiant eth0 par eth1, br0 par br1, et tap0 par tap1. maintenant quand je lance ma premiere machine virtuel je suis obligé de faire

service network restart

pour avoir access à internet sur ma machine hote et le tap1 marche une fois sur deux

voici mon ifcfg-eth0

# VIA Technologies, Inc. VT6102 [Rhine-II]
DEVICE=eth0
BOOTPROTO=none
BROADCAST=192.168.1.255
HWADDR=00:18:F3:0A:EC:EC
IPADDR=192.168.1.101
NETMASK=255.255.255.0
NETWORK=192.168.1.0
ONBOOT=yes
GATEWAY=192.168.1.1
TYPE=Ethernet
USERCTL=yes
PEERDNS=yes
IPV6INIT=no
NM_CONTROLLED=yes

voici mon ifcfg-eth1

# 3Com Corporation 3c905B 100BaseTX [Cyclone]
DEVICE=eth1
BOOTPROTO=dhcp
HWADDR=00:04:76:91:8B:93
ONBOOT=yes
DHCP_HOSTNAME=fixF8
TYPE=Ethernet
USERCTL=yes
PEERDNS=yes
IPV6INIT=no
NM_CONTROLLED=no

et mon ifconfig

et je n'ai plus internet sur mon hote

phenix01

Tu n'est pas obligé de créer un deuxième pont br1, je pense qu'en créant simplement un 2ème interface tap2 qui tu ajoutes au bridge br0 ca devrait suffire.

merci j'ai fait

brctl addif br0 tap1

et ca marche
une petite question

vbox est il bon pour faire de la virtualisation de serveur ?
