Ø Check if not only root can write on the nfs share (specially libvirt user).
It doesn’t look like permissions issue to me. Just to be doubly sure, I “touched” a file, in that folder, edited and deleted the file. All operations worked w/o error. As I have listed below, several files got created with correct user/group settings. In fact, “instance-00000005” folder itself was created with correct permissions. mandar@ubuntu-dev-mandar:/nfs_shared_instances_path/instance-00000005$ ll total 10944 drwxrwxr-x 2 mandar libvirtd 4096 2012-04-03 05:42 ./ drwxrwxrwx 4 root root 4096 2012-04-03 05:42 ../ -rw-rw---- 1 mandar libvirtd 0 2012-04-03 05:42 console.log -rw-r--r-- 1 mandar libvirtd 6291968 2012-04-03 05:42 disk -rw-rw-r-- 1 mandar libvirtd 4731440 2012-04-03 05:42 kernel -rw-rw-r-- 1 mandar libvirtd 1067 2012-04-03 05:42 libvirt.xml -rw-rw-r-- 1 mandar libvirtd 2254249 2012-04-03 05:42 ramdisk I also moved the mount point from “/” to my home folder – still didn’t help -Mandar On Tue, Apr 3, 2012 at 6:43 PM, Mandar Vaze / मंदार वझे <[email protected]<mailto:[email protected]>> wrote: I saw an old question posted here : https://answers.launchpad.net/nova/+question/164689 But I am not trying live migration.
