[Qemu-devel] [Bug 591666] [NEW] broken "pci_add auto storage"

[Eran Rom]

Public bug reported:

Doing:
(qemu) pci_add auto storage  file=/dev/ram0,if=virtio
Results in:
OK domain 0, bus 0, slot 5, function 0

However no device is actually added to the guest.
QEMU: Latest git code (June 9) from 
git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git
(seems to be broken from 0.12.1.2)
KVM: Compiled from git://git.kernel.org/pub/scm/virt/kvm/kvm-kmod.git
checked out (refs/remotes/origin/stable-2.6.32)

Both guest and host are Ubuntu 9.10 with 2.6.32 kernel.
Guest kernel has ACPI enabled (specifically, the PCI slot detection driver)

Guest executed with the following parameters:
 -boot c -drive 
file=/home/eranr/kvm_images/ubuntu-9.10-2.6.32-perf.img,if=ide,boot=on -m 4096 
-net nic,model=virtio -net tap,ifname=qtap0,script=no -vnc :0 -smp 
1,cores=1,threads=0 -monitor tcp:localhost:6001,server,nowait
