No it def. does not succeed. Only the first nic gets a reply from a tftp
server. It shows a menu and then does:
  localboot -1

which causes to go to the next boot device (pxelinux.cfg).

It then tries to boot from the 2nd nic. But there it gets only an IP
through DHCP but no tftp details or even an answer.

PS: this was working fine with Qemu 1.4.2

With one nic i see correctly - no bootable device restart in 1 sec.
With only two nics the "screen" just turns black and nothing happens at
all after trying PXE from 2nd nic. But no message and no restart.

DHCP yes tftp service no.
