Re: [Users] clone vm from snapshot problem in 3.2
Hi all, I am facing the same problem regarding the VM clone viewing the details from snapshot as Gianluca has described in this current thread. The single problem I am facing now, is that your thread is from 3 months old, I am using el6 stable repository on a CentOS 6.3 installation and my rpm list below looks like: ovirt-engine-sdk-3.2.0.10-1.el6.noarch ovirt-engine-webadmin-portal-3.2.1-1.beta1.el6.noarch ovirt-engine-setup-3.2.1-1.beta1.el6.noarch ovirt-engine-userportal-3.2.1-1.beta1.el6.noarch ovirt-engine-dbscripts-3.2.1-1.beta1.el6.noarch ovirt-engine-3.2.1-1.beta1.el6.noarch ovirt-engine-cli-3.2.0.11-1.el6.noarch ovirt-engine-tools-3.2.1-1.beta1.el6.noarch ovirt-engine-genericapi-3.2.1-1.beta1.el6.noarch ovirt-engine-backend-3.2.1-1.beta1.el6.noarch ovirt-engine-restapi-3.2.1-1.beta1.el6.noarch As I can see, there were some revision set updates on the ovirt engine core rpms, that I suppose, it should include this as well: http://gerrit.ovirt.org/#/c/11254/ Can someone provide me some piece of advice on how to fix things ? Thanks you. Alex.

Thanks, Liron. Hello, so I rebuilt with the patch. I built as in this thread: http://lists.ovirt.org/pipermail/users/2013-February/012702.html directly on engine server and with engine stopped: sudo rpm -Uvh --force $(ls -1|grep -v all) with $ ls -1|grep -v all ovirt-engine-3.2.0-4.fc18.noarch.rpm ovirt-engine-backend-3.2.0-4.fc18.noarch.rpm ovirt-engine-config-3.2.0-4.fc18.noarch.rpm ovirt-engine-dbscripts-3.2.0-4.fc18.noarch.rpm ovirt-engine-genericapi-3.2.0-4.fc18.noarch.rpm ovirt-engine-notification-service-3.2.0-4.fc18.noarch.rpm ovirt-engine-restapi-3.2.0-4.fc18.noarch.rpm ovirt-engine-setup-3.2.0-4.fc18.noarch.rpm ovirt-engine-tools-common-3.2.0-4.fc18.noarch.rpm ovirt-engine-userportal-3.2.0-4.fc18.noarch.rpm ovirt-engine-webadmin-portal-3.2.0-4.fc18.noarch.rpm and then reboot the engine Results: OK, for the snapshot details pane. It seem the patch fixes this too. Until now I was never able to see snapshot details, Instead now I can see disk and nic details. See: https://docs.google.com/file/d/0BwoPbcrMv8mvQmlCZTZBYjBadmc/edit?usp=sharing OK, if I clone a VM from a snapshot of a running VM (CentOS 5.6) I start the clone and no problem at all. well done! Corner cases and problems 1) OK, if I clone a powered on VM from a snapshot with two disks and here you can find clone in action with webadmin gui and iotop on node that shows they are cloning in parallel.. well! https://docs.google.com/file/d/0BwoPbcrMv8mvZ3lzY0l1MDc5OVE/edit?usp=sharing The VM is a slackware 14 32bit with virtio disk that I obtained from a virt-v2v from CentOS 6.3+Qemu/KVM The problem is that the cloned VM recognizes the disks in reversed order See these images where sl1432 is master slcone is the clone disk layout in details pane seems equal with boot disk the one that appears as the second, but the master boots ok, the slave no.

Hi Gianluca, Regarding the second item you mentioned - failure of the clone vm from snapshot, the engine log indicates that the following error occurred Volume Group not big enough - suggesting you might check if you have enough free space. Yes, you are right. I thought I had selected a storage domain with sufficient free space but probably it was not so. I just repeated the operation, creating a snapshot and then a clone of the same VM and selecting an SD with sufficient free space, and it completed correctly with the cloned VM able to boot. I take the occasion to suggest oVirt to at least behave this way: 1) pre-calculate necessary space and in case of problems don't start the clone operations but send a warning message impeding it If during 1) all was ok and in the mean time went KO (unexpected new storage allocated that made impossible clone completion) 2) notify the user with the actual problem (insufficient space) and not those crypic messages see the already pointed link: https://docs.google.com/file/d/0BwoPbcrMv8mvaW9OVW84WVI1dkU/edit?usp=sharing Thanks, Gianluca ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Hi Gianluca, Regarding the second item you mentioned - failure of the clone vm from snapshot, the engine log indicates that the following error occurred Volume Group not big enough - suggesting you might check if you have enough free space. Yes, you are right. I thought I had selected a storage domain with sufficient free space but probably it was not so. I just repeated the operation, creating a snapshot and then a clone of the same VM and selecting an SD with sufficient free space, and it completed correctly with the cloned VM able to boot. I take the occasion to suggest oVirt to at least behave this way: 1) pre-calculate necessary space and in case of problems don't start the clone operations but send a warning message impeding it If during 1) all was ok and in the mean time went KO (unexpected new storage allocated that made impossible clone completion) 2) notify the user with the actual problem (insufficient space) and not those crypic messages see the already pointed link: https://docs.google.com/file/d/0BwoPbcrMv8mvaW9OVW84WVI1dkU/edit?usp=sharing Those are indeed great improvement suggestions for a better user experience. It will be great if you could add it in bugzilla (as RFE) so it can be followed and managed there: https://bugzilla.redhat.com/enter_bug.cgi?product=oVirt Thank you!
