i tried to add the subnet to a hetzner root server (tried this: http://wiki.hetzner.de/index.php/Proxmox_VE and other tutorials) without success
no ping from host to guest and vice versa is possible. proxmox version 2.1-1
x.x.x.13 = main ip
y.y.y.120/29 = additional subnet
host (debian):
uname -a:
/etc/network/interfaces
sysctl config
guest 1 (ubuntu 12.04)
uname -a:
/etc/network/interfaces
a network restart on guest 1 will result in
ping of the host (inside guest)
any ideas abount this problem?
