[Users] issue with conversion of ESXi 5 centos VM to fedora19 ovirt host

[Madhav V Diwan]

hmm 

 well NFS says its open to the world


 exportfs
/var/lib/exports/iso-20131223154119
		0.0.0.0/0.0.0.0
/localstorage/nfs
		<world>
/var/lib/exports/iso
		<world>

this is what mount says 

server3.decllc.biz:/localstorage/nfs
on /rhev/data-center/mnt/server3.decllc.biz:_localstorage_nfs type nfs
(rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=10.0.8.106,mountvers=3,mountport=892,mountproto=udp,local_lock=none,addr=10.0.8.106)


 and its owned by vdsm adn group kvm 
 which is                            uid 36 and gid 36

[root at server3 ~]# ls -l /localstorage/
total 4
drwxr-xr-x  3 vdsm kvm    74 Dec 26 19:07 nfs


[root at server3 ~]# grep kvm /etc/group
kvm:x:36:qemu,sanlock
[root at server3 ~]# grep vdsm /etc/group
sanlock:x:179:vdsm
qemu:x:107:vdsm,sanlock
[root at server3 ~]# grep vdsm /etc/passwd
vdsm:x:36:36:Node Virtualization Manager:/var/lib/vdsm:/sbin/nologin


Does the NFS MOUNT itself need to be owned and operated by vdsm/kvm?
because i did not set up the mount .. ovirt-engine and vdsm do that

It looks like a problem with the permissions on your NFS export storage
domain. The machine running virt-v2v must be able to mount the storage
domain and write to it as uid:gid == 36:36.
