[Dnsmasq-discuss] pxe server uefi

[Robert]

Hi
i have a pxe server on rhel by which we install legacy bios client without
any problems.
Because soon we 'll have servers with only uefi , i'm trying to configure
pxe server to use also uefi.
Before to have bare servers I 'm using vm woth efi firmware on ESX 5.1
hosts.
I have used
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/s1-netboot-pxe-config.html
guides and many other howto.
My conf for legacy bios is

log-queries
no-resolv
no-hosts
localise-queries
addn-hosts=/etc/dnsmasq.hosts
log-dhcp
dhcp-authoritative

dhcp-range=my_net,192.168.1.10,192.168.1.100,255.255.255.0,12h
dhcp-option=net:my_net,6,192.168.1.2
dhcp-boot=net:my_net,pxelinux.0,pxe.intranet.fc,192.168.1.2

## TFTP
enable-tftp
tftp-root=/mnt/lib/tftpboot

In my uefi test I change
dhcp-boot=net:my_net,pxelinux.0,pxe.intranet.fc,192.168.1.2
with
dhcp-boot=net:my_net,bootx64.efi,pxe.intranet.fc,192.168.1.2

where bootx64.efi is recovered from a rhel 6.5 image and is put in
/mnt/lib/tftpboot.

At vmware vm boot I see that pxe server send answer to client but then no
more traffic, client does not request tftp files:

From tcpdump same results, clinet after answer from pxe server does not
make other calls to pxe for tftp files..
