Hi Dan,
Even with Glusterfs 4.3.2, we still need some extra steps to make
native integration with QEMU work, you can find more details from
http://www.gluster.org/community/documentation/index.php/Building_QEMU_with_gfapi_for_Debian_based_systems
As for the qcow2 image importing, you can do it in two ways:
(1) The FUSE approach:
mount -t glusterfs //brickServerIp/volumeName /mnt
qemu-img convert -f raw -O qcow2
path-to-the-source-raw-image-file /mnt/imageName.qcow2
(2) The native approach, e.g., qemu-img convert -f raw -O qcow2
path-to-the-source-raw-image-file
gluster://brickServerIp/volumeName/imageName.qcow2
Good luck!
Best Regards,
Bob

Hi,
I am trying to achieve the same thing. Why did you have to
enable QEMU native integration when Glusterfs 4.3.2 already has
native QEMU support?
How did you import the qcow2 image and how did you set it up.
Thanks,
Dan

Dear All,
I am using QEMU 1.7.0 and GlusterFs 4.3.2 and have carried out
necessary configurations to enable QEMU-Glusterfs native
integration (i.e., using libgfapi instead of FUSE).
On the server side, I have configured a volume named "image"
using two bricks on two different machines "brk1" and "brk2".
And a qcow2 image centos.qcow2 has been imported to
Glusterfs.
On the client side (e.g., the KVM host), the configuration
"-drive file=gluster://brk1/image/centos.qcow2" is used
when starting a KVM VM. The VM boots successfully.
When it's running, I shut down the machine brk1 on purpose and
want to see whether the KVM VM can automatically switch to use
"-drive file=gluster://brk2/image/centos.qcow2" (i.e., IP
failover). Unfortunately, the VM crashes.
I am writing to ask whether the feature "IP failover" in
QEMU-Glusterfs native integration is supported. Thanks so much
for your kind help!
Best Regards,
Bob ZHANG
