Mounting the NFS exports with no_root_squash solved the problem! In fact, I was able to successfully blockpull from one NFS mountpoint to another with only these steps (without making it transient): virsh snapshot-create-as --domain <vm_name> --disk-only --atomic --no-metadata --diskspec vda,snapshot=external,file=/path/to/nfs1/<vm_name>.qcow2 virsh blockpull --domain <vm_name> --path /path/to/nfs2/<vm_name>.qcow2 Since this works in libvirt 1.0.2 I imagine it will work just as well in libvirt 1.2.7 as well.
