DHCP interrupting remote install on Idrac

[gvmsf]

I am trying to install px ve 8.3 on a couple of Dell machines using Idrac's virtual CD option. This works fine when Idrac is on a dedicated port. However, some of the machines use a shared Idrac port. On those machines the Idrac / virtual CD connection is lost when px installer probes the network interfaces for an IP address. By the time the connection has recovered the installer has crashed with either a Dell Red Screen of Death or a kernel panic. I can bypass the issue by inserting a usb key with the installer and using that as installation source, but of course that's not really a remote install.
I could confirm the behaviour on Idrac versions 8 and 9
So - Is there an option, possibly using grub, to keep px installer from probing the network interfaces?

I already had this problem 10 years ago. I didn't looked forward.
Today, as a workaround, you can look at this : https://pve.proxmox.com/wiki/Automated_Installation

Thanks for the suggestion, but for me that's actually more effort than plugging in USB keys in those locations

I am surprised the devs did not look into this. I assume that a lot of people are using virtual ISOs to install on Dell, and a certain percentage of them will not have dedicated Idrac networks
