[libvirt-users] Libvirtd running as root tries to acces s oneadmin (OpenNebula) NFS mount but throws: error: ca n’t canonicalize path

Hey All,

I've an issue where libvirtd tries to access an NFS mount but errors out with: can't canonicalize path '/var/lib/one//datastores/0 . The unprevilidged user is able to read/write fine to the share. root_squash is used and for security reasons no_root_squash cannot be used.

On the controller and node SELinux is disabled.

[oneadmin mdskvm-p01 ~]$ virsh -d 1 --connect qemu:///system create /var/lib/one//datastores/0/38/deployment.0
create: file(optdata): /var/lib/one//datastores/0/38/deployment.0
error: Failed to create domain from /var/lib/one//datastores/0/38/deployment.0 error: can't canonicalize path '/var/lib/one//datastores/0/38/disk.1': Permission denied

I added some debug flags to get more info and added -x to the deploy script. Closest I get to more details is this:

2016-04-06 04:15:35.945+0000: 14072: debug : virStorageFileBackendFileInit:1441 : initializing FS storage file 0x7f6aa4009000 (file:/var/lib/one//datastores/0/38/disk.1)[9869:9869] 2016-04-06 04:15:35.954+0000: 14072: error : virStorageFileBackendFileGetUniqueIdentifier:1523 : can't canonicalize path '/var/lib/one//datastores/0/38/disk.1':


Comment is: "The current implementation works for local
storage only and returns the canonical path of the volume."

But it seems the logic is applied to NFS mounts. Perhaps it shouldn't be? Anyway to get around this problem? This is CentOS 7 .
