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 address"
you can configure it, sure, but you should not be able
to access anything outside of the vm.
another way to set this up, is, to configure the filter
vdsm-no-mac-spoofing for each vm
and to configure your network to not allow any other ip-packages
from the given mac, and assign well known macs to each vm.
you can also add vlans and proper subnetting to the mix to make
it more secure.
