[one-users] newbie how-to configure network to connect to the vm

[Nikolaj Majorov]

Hello,


I install open nebula 4.8 on centos 7 as described in quickstarts and confiture my private network as it was showed in example:

NAME = "private"

BRIDGE = br0

AR = [
    TYPE = IP4,
    IP = 192.168.0.100,
    SIZE = 3
]

Starting vm I have got IP 192.168.0.100, but  I can’t connect to the VM over ssh and even ping it. 
What should I do with network to access the VM ( add route/gateway  ) ?
I’m really newbie in the networking  , so please give some hints ..


So my network configuration is :

ifconfig -a

br0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 46.4.99.35  netmask 255.255.255.255  broadcast 46.4.99.35

and routing looks like this:

$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         46.4.99.33      0.0.0.0         UG    0      0        0 br0
46.4.99.33      0.0.0.0         255.255.255.255 UH    0      0        0 br0
169.254.0.0     0.0.0.0         255.255.0.0     U     1003   0        0 br0
192.168.122.0   0.0.0.0         255.255.255.0   U     0      0        0 virbr0

Many thanks for any hint !
