Description of problem: 82599EB pf driver inside win7sp1-32 guest can install as normal but not work. Download this driver from: https://downloadcenter.intel.com/Detail_Desc.aspx?lang=eng&changeLang=true&DwnldId=18713 Version-Release number of selected component (if applicable): qemu-kvm-rhev-1.5.3-21.el7.x86_64 3.10.0-61.el7.x86_64 How reproducible: always Steps to Reproduce: 1.Boot win7sp1-32 guest with 82599EB pf. # /usr/libexec/qemu-kvm -S -M pc-i440fx-rhel7.0.0 -cpu SandyBridge -enable-kvm -m 2G -smp 2,sockets=2,cores=1,threads=1 -name juli -uuid 355a2475-4e03-4cdd-bf7b-5d6a59edaa68 -rtc base=localtime,clock=host,driftfix=slew -device virtio-scsi-pci,bus=pci.0,addr=0x5,id=scsi0 -drive file=/home/juli/win7sp1-32.qcow2_v3,if=none,id=drive-scsi0-0-0,media=disk,cache=none,format=qcow2,werror=stop,rerror=stop,aio=native -device scsi-hd,drive=drive-scsi0-0-0,bus=scsi0.0,scsi-id=0,lun=0,id=juli,bootindex=0 -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 -k en-us -boot menu=on,reboot-timeout=-1,strict=on -qmp tcp:0:4488,server,nowait -spice port=5969,disable-ticketing -vga qxl -global qxl-vga.revision=3 -monitor stdio -monitor unix:/tmp/monitor1,server,nowait \ -device vfio-pci,host=05:00.0,id=hostnet_PF 2.Download pf driver and install it inside guest. Actual results: this pf driver can not works as well. The driver give the following info: This device cannot start. (Code 10) Expected results: win7sp1-32 pf driver can works well. Additional info:
Was the win7sp1-32bit guest fully updated? I don't have an 82599EB, but I was able to assign an X540-AT2 PF to a win7sp1 guest. The driver initially would not install saying it didn't detect and Intel adapter. After ~400MB of Windows Update, it installs and works as expected.

After win7sp1-32 guest update, can not install 82599 pf driver still. It will give warning: "Can not install drivers. No Intel(R) Adapters are present in this computer.".

Can a system with this configuration be made available for debug? We have no systems with 82599EB in the development lab and X540 has not reproduced the issue.
Reproduced. Testing various versions of the Intel driver I find: 18.4: Works 18.5: Works 18.6: Works 18.7: Works 18.8.1: Fail 19.0: Fail In all working cases the device is found and listed in device manager as an X520 and the Intel driver utilities available through device manager appear to work. I can't do any network testing since the provided test system does not have link. And the smoking gun, from the 18.8.1 release notes (http://downloadmirror.intel.com/23684/eng/readme.txt): Intel 10GbE Network Adapter Notes ================================= Release 18.7 is the last release in which Intel 10GbE Network adapters support 32-bit Microsoft Windows. Starting with Release 18.8, Intel 10GbE Network adapters do not support the following operating systems: * Microsoft Windows 7 (32-bit) * Microsoft Windows 8 (32-bit) * Microsoft Windows 8.1 (32-bit) QED
