Multiple IPs and Vms - Connection problems

[Profundus]

Hello,

I'm running a Proxmox Virtual Environment 4.2-2. Additional I have installed three VM with Centos 7.2.1511

Everything is fine. I can reach my servers and ping from host to proxmox works too. The problem is, that I cant ping from an vm to another vm. Errorcode: No Route to Host.

My configuration looks like:

# Loopback device:
auto lo
iface lo inet loopback

# device: eth0
auto  eth0
iface eth0 inet static
  address   xxx.xxx.56.100
  netmask   255.255.255.255
  pointopoint   xxx.xxx.56.65
  gateway   xxx.xxx.56.65
  up route add -net xxx.xxx.56.64 netmask 255.255.255.192 gw xxx.xxx.56.65 eth0

iface eth0 inet6 static
  address 2a01:4f8:172:1163::2
  netmask 64
  gateway fe80::1


auto vmbr33
iface vmbr33 inet static
    address xxx.xxx.56.100
    netmask 255.255.255.255
    bridge_ports none
    bridge_stp off
    bridge_fd 0
    bridge_maxwait      0
    up route add -host xxx.xxx.143.33/32 dev vmbr33
    down route add -host xxx.xxx.143.33/32 dev vmbr33

auto vmbr34
iface vmbr34 inet static
    address xxx.xxx.56.100
    netmask 255.255.255.255
    bridge_ports none
    bridge_stp off
    bridge_fd 0
    bridge_maxwait      0
    up route add -host xxx.xxx.143.34/32 dev vmbr34
    down route add -host xxx.xxx.143.34/32 dev vmbr34

auto vmbr35
iface vmbr35 inet static
    address xxx.xxx.56.100
    netmask 255.255.255.255
    bridge_ports none
    bridge_stp off
    bridge_fd 0
    bridge_maxwait      0
    up route add -host xxx.xxx.143.35/32 dev vmbr35
    down route add -host xxx.xxx.143.35/32 dev vmbr35

For details:
xxx.xxx.56.100 is my host (Proxmox)
xxx.xxx.56.65 the gateway
xxx.xxx.143.33 to 35 my vms

Thanks for any help.

Still no solution from my side.

Do I have to call it "up IP route add ..." ?

Hi,

I do not understand why you make for each VM an extra bridge?
May be this helps
