Hi everyone
I'm having a problem with UEFI PXE boot in VM environment.
I'm trying to create a PXE Server, so i've created a VM with Ubuntu 24, installed isc-dhcp-server and tftp-hpa. Compiled iPXE for both legacy and UEFI, and placed the files (undionly.kpxe and ipxe.efi) on the root folder of tftp (/tftproot/).
Then i've created another vm without any OS installed, to see if it would boot from pxe.
I've tried to boot using "SeaBios" and "OVMF".
If i boot with "SeaBios", it works.... but if i try to boot using "OVMF" i get the following message :
Already tried attaching an "EFI disk" and a "VirtIO RNG", but the result is always the same.
Can someone please help ??
I'm posting here the config files of the Ubuntu VM
/etc/netplan/50-cloud.init.yaml
/etc/default/isc-dhcp-server
The second interface (enp6s19) is there only to have internet so i can install packages
/etc/dhcp/dhcpd.conf
/etc/default/tftpd-hpa
I'm running both VM's on an isollated network.
The config files of the VM itself are :
PXEServer :
/etc/pve/nodes/proxmox/qemu-server/190.conf
and the vm for testing the pxeboot:
/etc/pve/nodes/proxmox/qemu-server/999.conf
Sorry for the big post, but i wanted to be as accurate as possible.
Thanks
Edit : forgot to attach a capture done with "tcpdump -w output.pcap port 67 or port 68 or port 69 or port 4011"
