[Libguestfs] Virt-v2v conversion issue

Hi, I am running virt-v2v under CentOS 7, I use the new libguestfs-1.27.48-1.1, and when I try to import my Windows 2008 (running perfectly using virt-manager) in my cloud oVirt, I encounter this issue : ........ libguestfs: trace: mkdir_p = 0 libguestfs: trace: case_sensitive_path "/Windows/system32/drivers/viostor.sys" libguestfs: trace: case_sensitive_path = "/Windows/System32/drivers/viostor.sys" libguestfs: trace: cp "/usr/share/virtio-win/drivers/amd64/Win2008/viostor.sys" "/Windows/System32/drivers/viostor.sys" libguestfs: trace: cp = -1 (error) libguestfs: trace: hivex_close libguestfs: trace: hivex_close = 0 virt-v2v: error: libguestfs error: cp: cp: cannot stat '/sysroot/usr/share/virtio-win/drivers/amd64/Win2008/viostor.sys': No such file or directory If reporting bugs, run virt-v2v with debugging enabled and include the complete output: virt-v2v -v -x [...] libguestfs: trace: close libguestfs: trace: internal_autosync libguestfs: trace: internal_autosync = 0 The virtio-win folder is present and viostor.sys also. Can you help me to debug this issue ? Thank you and have a nice day Alain ________________________________ Alain VONDRA Charg? d'exploitation des Syst?mes d'Information Direction Administrative et Financi?re +33 1 44 39 77 76 UNICEF France 3 rue Duguay Trouin 75006 PARIS www.unicef.fr<http://www.unicef.fr/> [cid:urgence_ebola258bf0]<http://www.unicef.fr> ________________________________
