troubles copying qcow2 VM images

[jurgen.depicker at let.be]

Dear all,

I'm facing a weird situation, trying to migrate from one storage pool (on 
VLET1, SWRAID1,SATA) to another (on VLET3, HWRAID1,SAS)
(all servers VLET1,2,3 on ubuntu 10.10)

1. I stop all running VM instances
2. On VLET3, I have an NFS share of VLET1 mounted
3. On VLET3, I issue: cp /mnt/nfs/VM1.qcow2  /srv/VMs/
4. I reconfigure VM1 to use the newly created copied /srv/VMs/VM1.qcow2

-> it gets mounted read-only apparently; it doesn't work.  When using 
rsync instead of cp, there's no difference...  I really don't understand 
what's going on...  Who has a clue please??

Kind regards,
Jürgen
