Hi All,
     I am trying to do a hotplug of a disk from VDSM (which uses
libvirt to get things done).
I hit the below error "operation failed: open disk image file
failed" comign from virDomainAttachDevice.

Some background:

1) The qemu-img create  cmd I use (inside vdsm) to create the file
being hotplugged is

/usr/bin/qemu-img create -f qcow2 -F qcow2 -b /rhev/data-center/000065de-04b8-42e2-986c-2de664708be7/11112d24-4cda-4200-8f6d-a1d8362c70fd/images/22224c45-6504-4ea1-bd24-12340017dd32/3333017d-1278-4bfb-8129-62bded257399
/var/run/vdsm/3333017d-1278-4bfb-8129-62bded257399' (cwd
/var/run/vdsm)

I even tried using the rel. backing path instead of abs. path as below..

/usr/bin/qemu-img create -f qcow2 -F qcow2 -b ../../../rhev/data-center/000065de-04b8-42e2-986c-2de664708be7/11112d24-4cda-4200-8f6d-a1d8362c70fd/images/22224c45-6504-4ea1-bd24-12340017dd32/3333017d-1278-4bfb-8129-62bded257399
/var/run/vdsm/3333017d-1278-4bfb-8129-62bded257399' (cwd
/var/run/vdsm)

but hit the same error during hotplug operation

2) qemu-img info /var/run/vdsm/3333017d-1278-4bfb-8129-62bded257399

What does this show

    qemu-img info  /rhev/data-center/000065de-04b8-42e2-986c-2de664708be7/11112d24-4cda-4200-8f6d-a1d8362c70fd/images/22224c45-6504-4ea1-bd24-12340017dd32/3333017d-1278-4bfb-8129-62bded257399
