[Qemu-devel] [Bug 318824] Re: DHCP/NAT: Vista fails to get IP from DHCP engine

[Ryan Harper]

What version of qemu is this?

Upstream qemu uses e1000 by default.  Checking guest config after
booting 32-bit Vista shows that e1000 adapter acquires an ip address
from userspace networking, however, I wasn't able to connect to
anything.  Switching the nic to rtl8193 allowed Vista VM to connect to
the internet.

Status in QEMU: Incomplete

Bug description:

Problem: When I use userspace networking - i.e. Qemu NAT engine with DHCP -
Vista 32-bit VM guest fails to recognize it.

The only way for Vista VM 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.

./qemu -hda WindowsVista-32-mypc.qcow2 -m 512 -snapshot -name Vista-32-mypc

btw: NAT itself works - after IPs are manually configured. Emulated NIC is
Realtek RTL8139. Same problem also exists with Intel E1000 NIC.
