Well I doubt this is a solution to this, anyway, if you want to check if it's a permission error due to not correctly configured selinux you could do: grep avc /var/log/auditd/auditd.log and configure your selinux correctly, no need to disable it. But I doubt that the VM can spoof the ip

Here's a workaround: define one logical network per vm assign IPs to these networks from a central instance assign one broadcast domain per logical network. so in other words: do correct subnetting. if you got a router who can't get spoofed you should be fine. HTH Am 25.06.2014 04:16, schrieb
