hello, i solved this problem.
For all that have this problem with read only file system and nfs.
For me , the problem was the NFS configuration (/etc/exports).
I just need to put no_root_squash in NFS option like above:
/var/lib/one/datastores 192.168.0.5(rw,sync,no_subtree_check,no_root_squash)

Assunto: [one-users] Opennebula read only VM root file system
Hello.
I´m using opennebula 4.2 and xen 4.2 with shared datastore. It´s all ok, but the vm file system is mounted iwth readonly.
I try the same image used by opennebula just with xen , and it works ok.
The NFS is all ok in client (xen) and server (opennebula).
But i saw some thing: my opennebula datastores is rwx for all (777) , but when opennebula create the vm image, it is 422 like above:
Does anybody knows how can i change this permissions in opennebula ?
