>Description:
Using virtio network driver in SmartOS' KVM, NetBSD-7 can not acquire a DHCPv4 lease ; it gives up and goes to link local address.

Because dhcpcd returns with success even if link local is configured, this causes some problem with the installer because /etc/resolv.conf is never created; therefore at the install step where /etc/resolv.conf is /bin/cp'd to /target/whatever, that command throws an error message. So , independent of the what I believe to be error in virtio driver, that part of the installer needs to be addressed.

Now, using an identical setup, I tested NetBSD-6.1.5 and it worked perfectly.

I then using an identical setup tested OpenBSD-5.8, and it also successfully acquired a DHCPv4 lease from my router.

So this seems to be very specific to NetBSD-7.0 release that I downloaded
>How-To-Repeat:
I downloaded the following ISO

ftp://mirror.planetunix.net/pub/NetBSD/images/7.0/NetBSD-7.0-amd64.iso

# cksum NetBSD-7.0-amd64.iso
3035928875 389777408 NetBSD-7.0-amd64.iso

(apologies that my smartos global zone does not have sha256 installed)
