Re: [Xen-users] Windows "modern.ie" Network Problem

[Wanderson Camargo <wandersonwhcr@xxxxxxxxx>]

Hi,

I reinstalled the box and network keeps unrecognized.

About your questions:

I removed the "type=ioemu" from configuration file and installed this MSI in guest.

Xen log:

$ tail -n10 /var/log/xen/qemu-dm-ie9-win7.log

As you said, I don't have a "-emu" now.

The "vif4.0-emu" is my Windows 7 Home, it works like a charm.

About my NAT question: I don't know, it looks like Xen is trying to create my Windows box with NAT and others with bridge. It's crazy, I know.

I don't remember which driver I installed, I tried a lot of them! Haha!

I'll try to convert and run the box again, without drivers.

But I have another boxes from modern.ie, clean, with the same problem.

Give me 1 hour, I'll check if it works.

OK, that's good thanks.

What does "brctl show" show?

You may need "ifconfig -a" to see it, if it isn't up. That would
indicate an issue with your hotplug scripts.

What are they? They might be interesting.

(network-script network-bridge)
(vif-script vif-bridge)

means you are using bridged and not NAT. In any case I don't think this
will be related to the problem you are seeing.

Ah, I've just noticed that your qemu log shows:
> Unknown PV product 2 loaded in guest
> PV driver build 1

Which indicates you have some PV drivers in your guest, which ones are
they? In general these drivers will unplug the emulated path as part of
switching to the PV path, i.e. vifX.Y-emu will disappear (as you've
observed) leaving you with just vifX.Y, however "type=ioemu" requests
that there be no PV path created. Try removing "type=ioemu" from your
vif config and I think the PV path should work.

If for some reason you want to use emulation and not PV drivers, then
remove or disable the in guest drivers. You will almost always want to
use PV drivers though, emulation can be rather slow.

Ian.
