This is actually a qemu bug: $ qemu-img create -f qcow2 -b /tmp/nosuchfile /tmp/overlay qemu-img: /tmp/overlay: Could not open '/tmp/nosuchfile': Could not open '/tmp/nosuchfile': No such file or directory: No such file or directory (That was with Fedora qemu-img-2.1.0-6.fc22.x86_64, but the same probably happens with qemu-kvm-rhev since they are very similar versions). I will add a workaround to libguestfs so it checks the file exists before running qemu-img. (In reply to Richard W.M. Jones from comment #2) > I will add a workaround to libguestfs so it checks the file exists > before running qemu-img. This will be fixed in virt-v2v 1.27.44. It now says: $ virt-v2v -i libvirtxml /tmp/bad.xml -o local -os /tmp [ 0.0] Opening the source -i libvirtxml /tmp/bad.xml virt-v2v: error: access: No such file or directory: /home/rjones/d/libguestfs/tests/guests/no-such-disk.img (In reply to Richard W.M.

But while i updated virt-v2v to latest version: libguestfs-1.27.58-1.1.el7.x86_64 virt-v2v-1.27.58-1.1.el7.x86_64 qemu-kvm-rhev-2.1.2-1.rwmj1.el7.x86_64 Getting the same result with bug description. steps: # virt-v2v -i libvirtxml rhel6.6-pv-x64-test.xml -o local -os /tmp [ 0.0] Opening the source -i libvirtxml rhel6.6-pv-x64-test.xml [ 0.0] Creating an overlay to protect the source from being modified qemu-img: /var/tmp/v2vovl32b9ad.qcow2: Could not open '/var/lib/xen/images/rhel6.6-pv-x64-test.img': Could not open '/var/lib/xen/images/rhel6.6-pv-x64-test.img': No such file or directory: No such file or directory virt-v2v: error: qemu-img command failed, see earlier errors If reporting bugs, run virt-v2v with debugging enabled and include the complete output: virt-v2v -v -x [...] so please help check whether there is something missed in the new version, thanks. I've added a workaround in virt-v2v 1.27.44. However the original bug still exists in qemu-kvm-rhev, therefore the component is correct. Reproducer: $ qemu-img create -f qcow2 -b /tmp/nosuchfile /tmp/overlay qemu-img: /tmp/overlay: Could not open '/tmp/nosuchfile': Could not open '/tmp/nosuchfile': No such file or directory: No such file or directory Hi,Ademar
This bug is now "MODIFIED",please help to add the fixed version for qemu-kvm-rhev component.
thanks

The bug is really in qemu (bug 1151043). We tried to work around the qemu bug in libguestfs, however doing that caused another problem, so I reverted the workaround. It has to be fixed in the proper place, and we cannot work around it in libguestfs / virt-v2v. |
