7.74 Oracle VM Server NIC Fails to Get IP Address if Configured for DHCP

In some cases, when you configure a network interface for Oracle VM Server to retrieve IP addresses via DHCP, and then bring up that interface, it cannot retrieve an IP address and the following error occurs:

Determining IP information for interface_name... 
failed; no link present. Check cable?

This issue can be caused when the time it takes the network interface to come up is greater than the time set for the LINKDELAY environment variable.

Workaround: Set the value of the LINKDELAY to a value of 10 or higher in the /etc/sysconfig/network-scripts/ifcfg-eth* file, as in the following example:

DEVICE=eth3
BOOTPROTO=dhcp
HWADDR=00:00:00:00:00:00
ONBOOT=yes
LINKDELAY=10
