Windows guest fail to receive IP address from dhcp

[lmr]

Hi guys,

when developing a Windows test I got a lot of No DHCP lease for MAC 9a:2b:2c:2d:2e:2f or ...can't verify address... messages. Followed by can't connect to guest test failures.

The problem is 100% reproducible (on my laptop):

1. Execute any test on Windows XP
2. killall qemu-kvm, rm -f env, rm -f /tmp/address_poll*
3. Execute any test on Windows XP

There is a simple fix, login to the machine (vnc or nc with the old IP address) and run "ipconfig /renew". It returns error:
An error occurred while renewing interface Local Area Connection 5 : Access is denied. or
An error occurred while renewing interface Local Area Connection 5 : Unable to contact your DHCP server. Request has timed out.
but the IP address changes successfully and is recognized by autotest.

Funny was that by using GUI Control Panel -> Network Connections -> Local Area ... -> Support -> Repair didn't work, but cmd ipconfig /renew did.

My idea is that windows won't send dhcp request on boot when the old (previous run) address is still valid. But don't take me seriously, I don't understand Windows...

My laptop: Fedora 17, qemu-kvm-1.0.1-1.fc17.x86_64, current autotest git-next
Guest: Windows XP SP3

PS: I sometimes encounter broken bridge which requires to stop and start bridge (in virt-manager) and then everything works fine. This is not the case and bridge restart doesn't help.
