T'm trying to convert XEN virtual machine image into raw. Source file is on NFS export and destination is also on nfs export. (both exports are mounted on migration servers RW access). I'm getting permission denied.
I have RW access to both exports - I can create, delete objects on both exports from migration server. But when I copy img file onto migration server local filesystem, conversion works, from local fs to nfs export. However when I tried to run guestfish against file located on NFS - I'm getting the same erro - Permission denied .
[root@kvm01 export]# virt-v2v -i disk migr01.img -o local -os /tmp

virt-v2v: error: libguestfs error: could not create appliance through

Try running qemu directly without libvirt using this environment variable:
export LIBGUESTFS_BACKEND=direct
Original error from libvirt: internal error: process exited while
