The nodes will not PXE boot. I see the standard install loads the Realtek r8169 driver. Based on past experience, my hardware requires the r8168 driver.

Can the NIC driver be changed in qlustar?

Do I execute the following commands at the root@cl-head~# prompt. Or from a different location?

apt-get install r8168 -dkms
rmmod r8169
lspci -s 3:00.0 -vv (verifies the r8168 driver is loaded)
reboot

thanks
