Public bug reported:
qcow2 [virtio-scsi] devices when mapped to the guest shows as 0MB
irrespective of the volume size.
Kernel Version: 3.10.0-rc5+
Libvirt Version: 1.0.6
Qemu Version: 1.5.50
Steps to reproduce the issue:
1. Create a qcow2 voulme using the command qemu-img create -f qcow2 virtio-scsi11.img 10G
2. Add the virtio-scsi controller
<controller type='scsi' index='0' model='virtio-scsi'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</controller>
3. Attach the qcow2 device to the guest, virsh attach-disk rhel64-64
/home/images/virtio-scsi11.img --persistent sdr --cache writethrough
4. Run the scan commnad echo ' - - - ' >
/sys/class/scsi_host/host#/scan, if the attached volume doesn't get
recognize.
5. Check the dmesg for the added volume.
6. Run fdisk -l command
Disk /dev/sdl: 0 MB, 197120 bytes
1 heads, 1 sectors/track, 385 cylinders, total 385 sectors
Units = cylinders of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
And observe that the 10G qcow2 volume shows as 0MB.
This is not seen with the raw image.
Disk /dev/sdm: 10.7 GB, 10737418240 bytes
64 heads, 32 sectors/track, 10240 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Expected Result:
The volume size for the qcow2 volumes should be shown correctly inside
the guest to avoid confusion.

I tried booting with the qemu and observed the same thing.
qemu-system-x86_64 /home/images/rhel64-64.qcow2 -drive
if=none,id=hd,file=/home/images/virtio-scsi11.img -device virtio-scsi-
pci,id=scsi --enable-kvm -device scsi-hd,drive=hd -m 2000
After creating the filesystem tried running the iozone and noticed disk
out of space issue.

Title:
qcow2 [virtio-scsi] devices when mapped to the guest shows as 0MB
irrespective of the volume size
Status in QEMU:
New
Status in Fedora:
New
Bug description:
qcow2 [virtio-scsi] devices when mapped to the guest shows as 0MB
irrespective of the volume size.
Kernel Version: 3.10.0-rc5+
Libvirt Version: 1.0.6
Qemu Version: 1.5.50
Steps to reproduce the issue:
1. Create a qcow2 voulme using the command qemu-img create -f qcow2 virtio-scsi11.img 10G
2. Add the virtio-scsi controller
<controller type='scsi' index='0' model='virtio-scsi'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</controller>
3. Attach the qcow2 device to the guest, virsh attach-disk rhel64-64
/home/images/virtio-scsi11.img --persistent sdr --cache writethrough
4. Run the scan commnad echo ' - - - ' >
/sys/class/scsi_host/host#/scan, if the attached volume doesn't get
recognize.
5. Check the dmesg for the added volume.
6. Run fdisk -l command
Disk /dev/sdl: 0 MB, 197120 bytes
1 heads, 1 sectors/track, 385 cylinders, total 385 sectors
Units = cylinders of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
And observe that the 10G qcow2 volume shows as 0MB.
This is not seen with the raw image.
Disk /dev/sdm: 10.7 GB, 10737418240 bytes
64 heads, 32 sectors/track, 10240 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Expected Result:
The volume size for the qcow2 volumes should be shown correctly inside
the guest to avoid confusion.

qemu-system-x86_64 -enable-kvm -m 1024 -cpu host,+x2apic \
-device virtio-scsi-pci,id=virtio-scsi0 \
-drive if=none,cache=none,file=test2.qcow2,format=qcow2,id=drive0 \

Works fine in qemu.git/master with a RHEL6.4 guest.
What happens when you run "blockdev --getsize64 /dev/sdb" in your guest?
Please also post the output of "qemu-img info
/home/images/virtio-scsi11.img" on the host.

Title:
qcow2 [virtio-scsi] devices when mapped to the guest shows as 0MB
irrespective of the volume size
Status in QEMU:
New
Status in Fedora:
New
Bug description:
qcow2 [virtio-scsi] devices when mapped to the guest shows as 0MB
irrespective of the volume size.
Kernel Version: 3.10.0-rc5+
Libvirt Version: 1.0.6
Qemu Version: 1.5.50
Steps to reproduce the issue:
1. Create a qcow2 voulme using the command qemu-img create -f qcow2 virtio-scsi11.img 10G
2. Add the virtio-scsi controller
<controller type='scsi' index='0' model='virtio-scsi'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</controller>
3. Attach the qcow2 device to the guest, virsh attach-disk rhel64-64
/home/images/virtio-scsi11.img --persistent sdr --cache writethrough
4. Run the scan commnad echo ' - - - ' >
/sys/class/scsi_host/host#/scan, if the attached volume doesn't get
recognize.
5. Check the dmesg for the added volume.
6. Run fdisk -l command
Disk /dev/sdl: 0 MB, 197120 bytes
1 heads, 1 sectors/track, 385 cylinders, total 385 sectors
Units = cylinders of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
And observe that the 10G qcow2 volume shows as 0MB.
This is not seen with the raw image.
Disk /dev/sdm: 10.7 GB, 10737418240 bytes
64 heads, 32 sectors/track, 10240 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Expected Result:
The volume size for the qcow2 volumes should be shown correctly inside
the guest to avoid confusion.

You created a qcow2 file but told libvirt it's type='raw'. Therefore
the guest sees a raw file and not a qcow2 file. The qcow2 file is only
196 KB on disk (qemu-img output shows this), this matches with the
blocksize --getsize64 output inside the guest.
Change type='raw' to type='qcow2' in your XML and the issue will be
resolved.

4. Run the scan commnad echo ' - - - ' >
/sys/class/scsi_host/host#/scan, if the attached volume doesn't get
recognize.
5. Check the dmesg for the added volume.
6. Run fdisk -l command
Disk /dev/sdl: 0 MB, 197120 bytes
1 heads, 1 sectors/track, 385 cylinders, total 385 sectors
Units = cylinders of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
And observe that the 10G qcow2 volume shows as 0MB.
This is not seen with the raw image.
Disk /dev/sdm: 10.7 GB, 10737418240 bytes
64 heads, 32 sectors/track, 10240 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Expected Result:
The volume size for the qcow2 volumes should be shown correctly inside
the guest to avoid confusion.

Thanks Stefanha.
If we use the commad virsh attach-disk rhel64-64 /home/images/virtio-
scsi11.img --persistent sdr --cache writethrough the qcow2 images will
also gets added as raw which is by default. Hence we should use
"virsh attach-disk rhel64-64 /home/images/virtio-scsi11.img --persistent
sdr --cache writethrough --sourcetype file --driver qemu --subdriver
qcow2".

Title:
qcow2 [virtio-scsi] devices when mapped to the guest shows as 0MB
irrespective of the volume size
Status in QEMU:
Invalid
Status in Fedora:
New
Bug description:
qcow2 [virtio-scsi] devices when mapped to the guest shows as 0MB
irrespective of the volume size.
Kernel Version: 3.10.0-rc5+
Libvirt Version: 1.0.6
Qemu Version: 1.5.50
Steps to reproduce the issue:
1. Create a qcow2 voulme using the command qemu-img create -f qcow2 virtio-scsi11.img 10G
2. Add the virtio-scsi controller
<controller type='scsi' index='0' model='virtio-scsi'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</controller>
3. Attach the qcow2 device to the guest, virsh attach-disk rhel64-64
/home/images/virtio-scsi11.img --persistent sdr --cache writethrough
4. Run the scan commnad echo ' - - - ' >
/sys/class/scsi_host/host#/scan, if the attached volume doesn't get
recognize.
5. Check the dmesg for the added volume.
6. Run fdisk -l command
Disk /dev/sdl: 0 MB, 197120 bytes
1 heads, 1 sectors/track, 385 cylinders, total 385 sectors
Units = cylinders of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
And observe that the 10G qcow2 volume shows as 0MB.
This is not seen with the raw image.
Disk /dev/sdm: 10.7 GB, 10737418240 bytes
64 heads, 32 sectors/track, 10240 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Expected Result:
The volume size for the qcow2 volumes should be shown correctly inside
the guest to avoid confusion.
