Test win2012-64 guest hit the same issue. Tit this issue on win8-64bit guest under q35. But met anther bug 920924 about '-drive...-global...' method fail to detect them correctly when add two floppies, that's the global problem, so i will open a new bug to tracking it. Best Regards. RHEL7 guest also has this problem. Attach a floopy "-drive file=floppy-1440K.vfd,if=none,id=drive-fdc0-0-0,format=raw,cache=none -global isa-fdc.driveA=drive-fdc0-0-0". In guest, there is no the device file /dev/fd0. The cmdline is as following: /usr/libexec/qemu-kvm -M q35 -cpu SandyBridge -enable-kvm -m 2048 -smp 4,sockets=2,cores=2,threads=1 -name rhel7 -uuid 6afa5f93-2d4f-420f-81c6-e5fdddbd1c83 -drive if=none,id=drive-disk,cache=none,file=rhel7.raw,format=raw,aio=native -device virtio-blk-pci,ioeventfd=on,drive=drive-disk,id=disk,scsi=off,config-wce=off,x-data-plane=on -netdev tap,id=hostnet0,vhost=on,queues=8 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=00:1a:4a:42:0a:00,vectors=17,mq=on -monitor stdio -spice port=5900,disable-ticketing -vga std -drive file=floppy-1440K.vfd,if=none,id=drive-fdc0-0-0,format=raw,cache=none -global isa-fdc.driveA=drive-fdc0-0-0 -qmp tcp:0:12345,server,nowait The kernel of host and guest is kernel-3.10.0-11.el7.x86_64. qemu-kvm is qemu-kvm-1.5.2-4.el7.x86_64. As most unattended Windows guest installation people would use floppy to store the answer file, this blocks it, raise to urgent/urgent and add testblocker Regards, Xiaoqing Per mail discussed, Q35 is a Tech Preview for RHEL7.0, removing the 'TestBlocker' keyword. Regards, Xiaoqing. RHEL7 guest should manually modprobe floppy. Then could recognize floppy inside guest correctly. So I think RHEL7.0 guest doesn't have this issue. Removed the Blocker+ since Q35 is a tech-preview. Created attachment 826586 [details]

Which versions of windows require floppy? Can the unattended install use CDROM instead? According to: http://technet.microsoft.com/en-us/library/dd349348(v=ws.10).aspx "Windows 7 Setup (Setup.exe) will begin automatically. By default, Windows Setup will search the root directory of all removable media for an answer file called Autounattend.xml." Since this is related to the new XML based answer file which is available starting with Windows 2008, I assume this is truth for every Windows version since then. *** Bug 1044878 has been marked as a duplicate of this bug. *** (In reply to Cleber Rodrigues from comment #13) > According to: > > http://technet.microsoft.com/en-us/library/dd349348(v=ws.10).aspx > > "Windows 7 Setup (Setup.exe) will begin automatically.

Hi Cleber, How about when using virtio-scsi-pci based devices ? a scsi-cd/scsi-hd itself needs vioscsi.* to drive, or use full virtualized cd-rom devices instead(ide/ahci) ? Yes, using a fully virtualized CDROM is exactly what I'd do. Here you can find a quick hack to virt-test to use a CDROM instead of a floppy.
