Summary: DHCP/NAT: Vista fails to get IP from NAT engine

Initial Comment:

Host: Fedora7/x64, KVM-83, Intel Core 2
Guest: Windows Vista 32-bit

Problem: When I use userspace networking - Qemu NAT engine with DHCP - Vista VM fails to reconginze it.

The only way for Vista to work is to manually set IP address:
IP: 10.0.2.2
Gateway: 10.0.2.15
DNS: 10.0.2.3

This problem does not happen with Windows XP VM.
It happens with older KVMs too... tested since KVM-75...

./qemu-kvm -hda /isos/disks-vm/alexeye/WindowsVista-32-mypc.qcow2 -m 512 -snapshot -name Vista-32-mypc

Message:
I've found this problem is common (but not consistent) on both Vista and
Windows 7 guests, using kvm-82 and kvm-83, with rtl8139, e1000 or virtio.
There's something about these specific Windows releases that breaks with
KVM/QEMU DHCP.

Since this also happens with -no-kvm , I opened a similar bug in Qemu

Message:
Same happens with -no-kvm (Qemu) and with e1000 NIC (instead of RTL8139).

Message:
btw: NAT itself works - after IPs are manually configured. Emulated NIC is
RTL8139.
