XEN 4.4 如何在 Debian Jessie(OVH)上为 dom0 和 domu 配置不同的 IP 子网

XEN 4.4 如何在 Debian Jessie(OVH)上为 dom0 和 domu 配置不同的 IP 子网

请帮助配置 dom0 网络。dom0 主机是 Debian jessie。我需要配置 domu 以接受来自 OVH 中的 ip main(dom0)的不同子网。这是我的网络拓扑:

A.B.C.254 ---- A.B.C.81
(Gateway)       (br0/dom0)
               X.Y.X.150 ---- X.Y.X.144 - X.Y.Z.149 (domu)
                (br1/dom0)

这是我的 dom0 /etc/network/interface:

auto eth0
iface eth0 inet manual

auto br0
iface br0 inet static
   bridge_ports eth0
        address A.B.C.81
        netmask 255.255.255.0
        network A.B.C.0
        broadcast A.B.C.255
        gateway A.B.C.254
   bridge_stp on
   bridge_maxwait 0
   pre-up /sbin/ipset restore < /etc/ipset.up.rules
   pre-up /sbin/iptables-restore < /etc/iptables.up.rules

auto br1
iface br1 inet static
        address X.Y.X.150
        netmask 255.255.255.248
        broadcast X.Y.X.151
   pre-up brctl addbr br1

输出形式 route -v

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         A.B.C.254  0.0.0.0         UG    0      0        0 br0
A.B.C.0    *               255.255.255.0   U     0      0        0 br0
X.Y.X.144  *               255.255.255.248 U     0      0        0 br1

IP 路由的输出:

default via A.B.C.254 dev br0
A.B.C.0/24 dev br0  proto kernel  scope link  src A.B.C.81
X.Y.X.144/29 dev br1  proto kernel  scope link  src X.Y.X.150

brctl show 的输出

# brctl show
bridge name     bridge id               STP enabled     interfaces
br0             8000.e03f49e8149b       yes             eth0
br1             8000.feffffffffff       no              vif3.0

从 dom0,我可以 ping br1 和 br1,但不能 ping domu,并出现错误“您想 ping 广播吗?然后 -b”。只能使用 -b 选项

# ping X.Y.Z.144 -c 2 -b
WARNING: pinging broadcast address

rtt min/avg/max/mdev = 0.127/0.145/0.163/0.018 ms

从 domu,我可以 ping 通 br1 和 br0,但无法 ping 通互联网(8.8.8.8)从外部,我可以 ping 通 br0 和 br1,但无法 ping 通 domu。

真诚地感谢 Manu Purba

我将 domu ip 从 XYZ144 更改为 XYZ145。我无法使用 XYZ144 从外部进行网络 /29 ping:

>ping x.y.z.145

Pinging x.y.z.145 with 32 bytes of data:
Reply from x.y.z.145: bytes=32 time=276ms TTL=50
Reply from x.y.z.145: bytes=32 time=270ms TTL=50
Reply from x.y.z.145: bytes=32 time=288ms TTL=50
Reply from x.y.z.145: bytes=32 time=269ms TTL=50

Ping statistics for x.y.z.145:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 269ms, Maximum = 288ms, Average = 275ms
