DHCP misbehaves under Vista (like bug 2519737)

DHCP misbehaves under Vista (like bug 2519737)

[Duck]

32-bit Vista (SP1) DHCP client doesn't acquire an IP address when using 
'-net user'. (Userspace networking does work if IP assigned by hand.) 
IPCONFIG /RENEW times out after a longish time.

Interestingly, DHCP worked fine after initial install of the Vista OS
(using E1000 card), but failed after the next reboot.

Hmmm. Doubting myself, I switched to RTL8139. Vista updated its drivers on
startup and DHCP worked fine again, but failed after next reboot and
hasn't worked since.

DHCP with '-net user' is working fine in XP3 guests.

Rarely use Vista so I only noticed this at kvm-82, and again with -83.

Host is 32-bit Slackware 2.6.27.7-smp with own-built kvm-83 binaries
and kernel modules.

Avi just fixed it in qemu. You can take the patch with this subject:
