it looks like it is looking up 'lo' inside the guest,
you might try to add 127.0.0.1 as a separate 'nodev'
entry to the guest, or to disable the hide_netif flag

you might also try to 'change' the configuration of
that pxe server to _not_ use 127.0.0.1 (and use localhost
or the first assigned ip instead)

CAP_NET_BROADCAST is not used, so it's unlikely you need
that one ... but it doesn't hurt either :)
