hello michal,
Yes, both paths are correct and working on the source host since the VM starts and works
correctly on source host. Nevertheless I have checked with fdisk and mount to assure that
these devices are indeed reachable.
Please understand that my setup is the following:
source host : KVM (hosting the VM to migrate)
target host : oVirt 4.0.4 (patched)
The error "no storage vol with matching path '/dev/sdc'" is returned by
the target host script /usr/lib/python2.7/site-packages/vdsm/v2v.py.
This almost seems normal since the device /dev/sdc is not mounted on target host (where
script is running) but only on source host.
Can this be the source of the error ?
cordialement, regards,

hello,
any news on this issue ?
Hi, Shahar is out on vacation for few weeks
can I do anything to help ?
hm...looking at the error, can you please confirm those paths
('/dev/mapper/vg_00-lv_sys’, /dev/sdc) are mounted/correct on the source host?
Seems like the patch works and adds those disks all right, but further queries fails
indicating those disks are not reachable.
Thanks,
michal
