[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

Hi Eran,

Could you lauch "lspci" command on guestOS to see whether there is a new
pci device hot-plug in?

On the other hand, the guestOS need to  be configured with "CONFIG_VIRTIO_PCI", otherwise it can not
contain the driver to monitor the virtio-pci device.

Thanks

[Pierce Liu]

If configure guest kernel correctly, it seems that virtio for block is OK!
Could you help or send me your configure file to have a second check

Thanks


======== version info ===============
QEMU 0.14.50 monitor 
host kernel: 2.6.39 
guest kernel: 2.6.32  


======== config file for kernel  info ===================
See attachment

=========Doing on qemu monitor ================
QEMU 0.14.50 monitor - type 'help' for more information
(qemu) pci_add auto storage file=/dev/ram0,if=virtio
OK domain 0, bus 0, slot 3, function 0


=========Doing on guest console ===============
1.  ---see the disk on guest
root@qemux86-64:~# dmesg | grep 'vda'
[  245.440217]  vda: unknown partition table
root@qemux86-64:~# fdisk -l

Disk /dev/sda: 2147 MB, 2147483648 bytes
255 heads, 63 sectors/track, 261 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sda doesn't contain a valid partition table

Disk /dev/vda: 16 MB, 16777216 bytes
16 heads, 63 sectors/track, 32 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

Disk /dev/vda doesn't contain a valid partition table

2. --- write content to virtio disk

root@qemux86-64:~# echo 'helloHypervisor' > /dev/vda  
root@qemux86-64:~# head /dev/vda 
helloHypervisor


=========Doing on host console =============

[root@oc8440477808 linux-2.6.39]# head /dev/ram0
helloHypervisor


========= conclusion ====================
Host get the data which is passed through virtio device on guest. The data is "helloHpervisor"

So, the kernel version 2.6.32 can support virtio block device with correct
config, especially the following must be choosen:


CONFIG_VIRTIO=y
CONFIG_VIRTIO_RING=y
CONFIG_VIRTIO_PCI=y
CONFIG_VIRTIO_BALLOON=y
CONFIG_VIRTIO_BLK=y

Did you remember to load PCI hotplug modules into the guest?
sudo modprobe acpiphp
sudo modprobe pci_hotplug

this is vikas pandey,

1:would u please give me ur kernel and initrd source to me ..am also
trying to add pci and usb device in guest os ..

2:
i am using qemu and i am abe to run some of kernel image  and initrd which is available on qemu site for testing purpose.
now my ami is to connect the host usb and access the content after running  iso image or specifing kernel and initrd image on qemu .

for this task i have followed some procedure which is inlined....

[T. Huth]

The "pci_add" command has been removed since QEMU 2.3.0, so I guess we
can close this bug ... if you still can reproduce the problem with the
latest version, please feel free to open this ticket again.
