Good day all,

I just migrated from ESXi to Proxmox a Windows server VM, acting as a PXE server for both other VMs on the server, and physical computer connected to the server.
Migration went fine and I got the Windows server VM starting and running fine.
When I attempt o get a physical computer booting from the VM, I have a PXE error saying "no valid offer received".
I know however the network works, because an IP address is given to the computer by the DHCP role of the virtual server.
In the management panel of the virtual server, I have however a warning saying "DHCP service does not process any DHCP V4 client because no active network interface has a static IP V4 address configured".
On the virtual server, the network interface is actually configured with a static IP address.
On the management interface of the Proxmox server I see a vmbr0 interface for the server VM.
This vmbr0 interface is seen active with a slave (ens1f0np0) in the physical Proxmox server management tab.

I'm stuck, and would take with thanks any hints.

Regards to you all
