4.4 Container no connected to another nodes

[tato]

I made a environment with 3 proxmox 4.4 local vmware machines and one machine with proxmox 4.4 in another physical machine.

Local machines have configuration: 1 gigabyte RAM and 50 gigabytes of hard-drive. Each machine is a node and each node I created one container (LXC).

I configured by example one container in one vmware local machine:

Private static ip: 192.168.1.196/24
Gateway IPv4: 192.168.1.1

These container can access with web console vnc. Almost always cannot access with these console vnc. Another problem is ip static of container cannot access from another nodes. (I used nmap with -Pn). It seems a network failure or it could be miss configuration?

What information is needed to debug this problem?
Are there any suggest or opinion to solve or workaround this problem?

Thank you in advance,
Daniel

Private static ip: 192.168.1.196/24
Gateway IPv4: 192.168.1.1

The virtual host @ vmware can be accessed via ssh-console?

If yes, the container (in the following example "111")can be attached by

lxc-attach -n 111

and the internal settings can be checked, e.g.

ifconfig
route -n

These container can access with web console vnc. Almost always cannot access with these console vnc. Another problem is ip static of container cannot access from another nodes. (I used nmap with -Pn). It seems a network failure or it could be miss configuration?

follow the ip packets within the virtual network by

tcpdump -e -n -i eth0

etc. in order to figure out where the get lost.

I accessed from vmware host and attached to container with:

lxc-attach -n 111

I made a ping from container to host vmware and it success:

20:14:42.309775 fe:a2:23:a9:61:29 > 00:0c:29:12:86:a1, ethertype IPv4 (0x0800), length 98: 192.168.1.197 > 192.168.1.193: ICMP echo request, id 1991, seq 23, length 64

But when I throw same test inside container to another node vmware throw one failure:

20:05:03.501807 fe:a2:23:a9:61:29 > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 42: Request who-has 192.168.1.191 tell 192.168.1.197, length 28

How can I solve it?

Thank you Richard,

Question is: where is 192.168.1.191 and does the ARP request arrive there?

You mentioned "vmware" - a typo? Do you mean "Proxmox host"?
