vm PXE not working

[oldgeek]

Hi guys, I'm pretty new to proxmox. I'm having troubles in start a vm with pxe boot.
My version is:
root@clsproxmox:~# pveversion -v
proxmox-ve: 6.3-1 (running kernel: 5.4.73-1-pve)
pve-manager: 6.3-2 (running version: 6.3-2/22f57405)

I'm setup my pxe server as I usually set for the physical servers and I create a PXE file:
vi 'gethostip -x myserver'

default RHEL8.4
label RHEL8.4
kernel vmlinuz8 console=ttyS0,115200
append initrd=initrd8.img ks=nfs:nfssrv01://u2/sysadmin/images/kickstart/rh8.4.vm.ks.cfg inst.repo=nfs:nfssrv01:/u2/sysadmin/images/rhel-8.4-x86_64-dvd.iso console=ttyS0,115200n8 console=tty0

when I start the vm I get the address given by the dhcp server (with dhcp parameter: filename "PXE/pxelinux.0") correctly, then:

Filename: PXE/pxelinux.0
Nothing to boot: No such file or directory (http://ipxe.org/2s03e13b)
No more network devices

I'm using tftp pointing to PXE/pxelinux.cfg directory where are my PXE files (like above).

Could someone give me some advice?

Thank you

No more network devices

How is the VM configured? Especially what kind of type is the NIC? Maybe try another model?
