Ok, let`s test without kvm vm. Remove VMAC add ips on host => http://docs.ovh.ca/en/guides-network...an-derivatives
Ok, look good. Start ping or ssh root@178.33.98.15 => and not work, no ping, no ssh connect to 178.33.98.13 | 178.33.98.14 | 178.33.98.15

alvaroag , no ping from VM to 149.202.201.254
Try all 4 ips, try recreate VMAC.

Can you ping your gateway?
Also, try removing the VMAC, and creating a new one.

Also, I try get tcpdump on node and get some strange ARP spam.

Today I buy test subnet /30
And start add virtual MAC (need for kvm vm)
I cant create MAC for ip 178.33.98.13). I try again and again, but
Ok, I get 178.33.98.12 with MAC 02:00:00:fd:6f:8e
Then I start install KVM VM.
On host => Change sysctl => add
On host => Change network => brigde.
Then I install VM (debian 7) and edit interfaces (my host ip 149.202.201.105 => so I use 149.202.201.254)
http://docs.ovh.ca/en/guides-network...chbang-steamos
I try ping 8.8.8.8 and suddenly it`s not work (on my other servers it`s work fine).
Ok, I check all settings again and again but I dont found a mistake.
Well, then I try Move the failover IPs (subnet) to another server (where same settings VM network -> work)
And suddenly I logout from manager, lol!
How can I fix this?
