PXE boot to the K2000 using EFI in VSphere
Hello,
Is anyone able to successfully PXE boot EFI images in vSphere? Our workstations are able to PXE and bring down the image using efi with no problem, but virtual images we are not. We were able to capture images with ease using legacy bios in VMware but not with efi. If anyone has any information on this issue it would be much appreciated.
Thank you,
VMware 6.5
K2000 6.0.425

--I can't Edit my original Answer--
So I decided to spin up an Ubuntu 14 VM, and installed that ISC DHCP, got it working for both Legacy and UEFI at the same time. :)
Tested with VMWare devices, BIOS and EFI, all good. KACE SDA version 6.x.
Here is my conf file, I will write up an Article about it:

Where 192.168.46.5 is the KACE SDA IP.

It is perfectly possible, first make sure your DHCP for that VM Network is configured to handle UEFI PXE requests:
https://support.quest.com/kace-systems-deployment-appliance/kb/217556/dhcp-configuration-for-bios-and-uefi-pxe
Probably the Scope where those VMs are stored, doesn't have the Options set for UEFI, check your DHCP.
Also make sure the Network Adapter type is E1000, not E1000E or VMXNET3.

Thank you for the response. DHCP is configured correctly and the VMs are in the same scope. Anytime I go to boot to the EFI Network on the VM I receive >>>Start PXE over IPv4. It does not proceed any further. - agahlbeck 5 years ago

That means the VM is unable to find a DHCP in charge of routing UEFI requests.
If BIOS works fine, then it is a DHCP\Compatibility issue, again make sure the NIC type is E1000.
What type of DHCP do you have? - Channeler 5 years ago-
NIC is set to E1000
DHCP type is ISC 4.3.5
I agree it does seem like a compatibility issue . - agahlbeck 5 years ago -
Linux?, Could you post the current configuration? - Channeler 5 years ago

New PXE boot for KASE
next-server 172.30.10.50;
filename "ipxe.efi";
option tftp-server-name "172.30.10.50";
option bootfile-name "ipxe.efi"; - agahlbeck 5 years ago -
Try to follow this method:
option k2000-option244 code 244 = ip-address;
option k2000-option244 172.30.10.50;
next-server 172.30.10.50;
filename "ipxe.efi";

Do you know if that ISC can be deployed to Ubuntu Workstations OS, or is that for Ubuntu Servers only? - Channeler 5 years ago

All our workstations are windows and can pxe boot using efi with no problem. Its only when I create images using efi in vsphere that I have the problems. - agahlbeck 5 years ago
-
Are those workstations using that same DHCP? - Channeler 5 years ago
-
I will try that method and let you know the result, thanks. - agahlbeck 5 years ago

Correct the workstations use the same dhcp. - agahlbeck 5 years ago

Will the config file work for Windows servers? - agahlbeck 5 years ago
-
it should work with anything, iPXE does not care about what OS is being executed.
It's a deal between the BIOS and the TFTP server.
I am able to iPXE and load KBEs to machines that don't have a HDD/SSD installed.
NOTE: if you are talking about using that Config file with a Windows DHCP Server, then no, that is only for Linux. For Windows, read this article:
