        Actually, I believe I am still running 0.9.10, because once I had it
going, I figured "if it ain't broke don't fix it".  Regardless, I too have
the yellow exclamation point on the devices you are wanting to be hidden,
and simply don't worry about it.  I haven't experienced the issue you were
posting a solution too, I was only posting my thoughts regarding the change
you made vs everything else I have seen while keeping up with the GPLPV
drivers in the list because I was under the impression that you had made the
rtl8139 not show up to Windows.  Regardless, my disk config is (and always
was, including before GPLPV):
disk = [ 'phy:/dev/sdc,hda,w' ]
and the log information is:
[2009-09-09 12:44:06 2506] INFO (XendDomainInfo:1458) createDevice: vbd :
{'uuid': '6dc4c0b8-e283-0196-ae7e-a48f1ee8cf60', 'bootable': 1, 'driver':
'paravirtualised', 'dev': 'hda', 'uname': 'phy:/dev/sdb', 'mode': 'w'}

AFAIK GPLPV drivers since version don't have xenhide.sys, but I
don't know how this drivers functionality was replaced. After installation
of newest GPL PV drivers ( or my windows HVM on Xen 3.2
(debian lenny) still has two not working (yellow exclamation mark) devices
(rtl8139 and intel PCI BUS IDE). Do you have any tips to force this devices
to be hidden?

During windows installation I had such disc configuration:
disk = [ 'phy:/dev/xenvg/sbs,ioemu:hdc,w' ]
and after installation of GPL PV drivers I removed ioemu:
disk = [ 'phy:/dev/xenvg/sbs,hda,w' ]
This leads to such informations in logs:
[2009-10-07 18:33:26 2359] INFO (XendDomainInfo:1514) createDevice: vbd :
{'uuid': '0b8b11fb-f002-a92a-9752-0825c308a23f', 'bootable': 1, 'devid':
768, 'driver': 'paravirtualised', 'dev': 'hda', 'uname':
'phy:/dev/xenvg/sbs', 'mode': 'w'} 
which should by correct in my opinion. Could you check your logs?

Temat: RE: [Xen-users] SOLUTION: GPL PV xen net settings

        The vbd type is news to me.  You shouldn't have to do that, as the
GPLPV drivers should hide the rtl8139.  In the past, there was occasionally
an issue where the drivers wouldn't hide the HVM HD, causing corruption
because of parallel hard disks, but I don't recall such an issue with
networks at all.  Assuming the vbd type means pv only, then if there were a
type=vbd option for disk drives as well, that would prevent such a disaster,
and possibly (with a different installation procedure) allow for a
functional HVM CD-Rom drive in versions prior to 3.4.x (type=vbd on HD but
not CD-Rom, potentially along with a different, not necessarily existent
boot.ini setting).  I don't know whether or not the type option even exists
for HDs, or whether my theory is accurate regardless, but the thought is out
there now if anyone wants to mess with it.

I wasted a lot of time digging internet for how to make GPL PV xen net
drivers working on domU win2k3-sbs (xen-3.2). My problem was loosing IP
configuration because of parallel devices rtl8139 and xen net. After
vif = [ 'bridge=eth0,mac=00:16:3e:4a:0c:f4,type=vbd' ]
this problem has disappeared. Now windows sees only one network device.

Sorry for making noise if this is obvious for some of you.
