No ethernet interface found for seeding global EID. You will have to set it manually

As stated , you would need to do that in udev and reboot before anything that expects eth0 to be there would work.

likely something like

sed -i ‘s/venet0/eth0/’ /etc/udev/rules.d/70-persistent-net.rules

That way , the kernel still sees the venet0 interface but the os will refer to it as eth0

EDIT . . .

You would then of course need to adjust your

/etc/sysconfig/network-scripts/ifcfg-*

scripts to concur with the new name. Perhaps easiest to just

cp /etc/sysconfig/network-scripts/ifcfg-vnet0 /etc/sysconfig/network-scripts/ifcfg-eth0

but check to make sure.
