But I guess the second one is difficult to find out, as the OS in the VM and probably also the VM layer do some caching in memory and the write back to the image is delayed for a longer time. Are the steps which I followed are correct ..? I do not think, that this is really supported from ONE. You are taking an image away from a running VM (even in the state suspended), which could have an not cleanly saved state of the file system in the image. It is much better to use an OS and VM which does support ACPI and then use the 'onevm saveas ' and 'onevm shutdown ' commands. bye Fabian ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

And also there are no errors in the log file . why this cant save the VM ..? Because it could not write the file /srv/cloud/one/var//images/e0561a492c9aaac280479f2f0d85dcced9156fbf as the log file you have posted shows. Is the oneadmin user able to write into this folder? Also check your configuration, this // is not normal (but usualy should not be a problem). Eventually you have set / at the end of the paths in your oned.conf, remove it. Note: I use nfs for transferring the image . You need to have the folder /srv/cloud/one/var/images/ also available on the cluster node and there the user oneadmin (or eventually libvirtd) needs to be able to write into it. bye Fabian ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
