[ovirt-users] oVirt 4.2 - Removed disk remains in VM OS with hooks?
I am having an issue where when I use the REST API to connect a snapshot from another VM to a Backup-Appliance-VM, after the clone when I remove the Disk and delete the Snapshot, the disk remains in the Backup-Appliance-VM as /dev/sdb ot /dev/vdb. If I reboot the Bakup-Applicance-VM the disk disappears. If I manually remove the disk by "echo 1 > /sys/block/sdb/device/delete² the disk will disappear, but if I rescan the scsi bus, it is found and shows up again in the VM OS, but the oVirt WebGUI does NOT show it as connected. I am also not able to attach any other disks as it complains of : HotPlugDiskVDS failed: internal error: unable to execute QEMU command '__com.redhat_drive_add': Duplicate ID 'drive-scsi0-0-0-2' for drive I did see that others in the past have gotten around this issue by rebooting the Backup-Appliance-VM and then continuing on with the next VM backup and looping through backup-reboot-backup-reboot-etc. Anyone have an idea on how to solve this issue and remove the hooks from the guest OS? Steps to reproduce this issue: 1. Create a backup appliance VM to be used for the backup script execution 2. Currently I have the Vms set to virtio with threaded I/O enabled. Also tried virtio_scsi with same result. 3. Using REST API make snapshot of target VM 4. Using REST API fetch vm metadata 5. Using REST API attach the snapshot/disk to the Backup-Appliance-VM 6. dd the drive to backup folder 7. Using REST API remove the disk from the Backup-Appliance-VM 8. Using REST API delete the snapshot 9. ** Check the guest OS of the Backup-Appliance-VM and the mounted drive from the backup above still appears and behaves as mentioned in comments above. A second issue is that the above wont work when I have the Vms running on MPIO iSCSI storage, so for testing I have moved to NFS4. Anyone have ideas about either issue, I¹d love to hear ;) Thanks Irc.oftc.net #ovirt zipur ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[ovirt-users] Snapshot Disk fails to connect to BackupApplianceVM - Failed to HotPlugDiskVDS
Okay, when I do a snapshot, and then mount the snapshot to a
BackupApplianceVM, all works using NFS4 as my Storage Domain for the VM
being backed up. If I change that disk storage on the VM to be backed up to
my iSCSI storage, my script breaks and I see these errors in the oVirt

Re: [ovirt-users] oVirt 4.2 WebUI Plugin API Docs?
Hi Alexander,
If I try the following:
var api = parent.pluginApi('HelloWorld');
api.register({
UiInit: function () {
api.addMainTab('FooTab','xtab123','<a rel="nofollow" href="http://foo.com/">http://foo.com/</a>');
}
});
api.ready();
I get the error in my browser console:

However if I remove the line:
api.addMainTab('FooTab','xtab123','http://foo.com/);
And replace it with something simple like:
alert(Test 123¹);
There are no errors and the alert fires as it should.
Any ideas of what I might be missing?
I am running oVirt 4.2.1 on CentOS Hosted Engine setup with 1 host for
testing.

[ovirt-users] oVirt 4.x - RestAPI - Backup - How to Image Inactive Disk
Hi All, I have created a bash script that uses curl and the REST API based on the docs that I could find. I have the script working all the way up until the VM-ToBeBackedUp-Disk is attached to the VM-RunningTheBackupScript with the mention of the Snapshot. Example: https://-myFQDN-/ovirt-engine/api/vms/-UUID-OF-VM-RunningTheBackupScript/dis kattachments/ The above results in an attached disk to my VM-RunningTheBackupScript. The question I have is how to I image that disk from the VM-RunningTheBackupScript? The VM-RunningTheBackupScript is running Debian8 and that VM cannot see the attached disk as it is Inactive. I have reviewed many of the older scripts out there and it looks trivial, however everything I have tried has no joy ;/ If anyone on the list knows of the required magic, please advise ;) * If I have to go to using python etc, I will, but trying to avoid it if possible. Either way, I need some examples of how to proceed. Some links I have reviewed: https://www.ovirt.org/develop/api/design/backup-api/ http://200.1.19.60/ovirt-engine/docs/manual/en-US/html/Administration_Guide/ sect-Backing_Up_and_Restoring_Virtual_Machines_Using_the_Backup_and_Restore_ API.html https://markmc.fedorapeople.org/rhevm-api/en-US/html-single/index.html https://github.com/voidloop/ovirt-bash-backup/blob/master/backupvm.sh https://github.com/laravot/backuprestoreapi/blob/master/example.py Thanks Zip ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

I understand why the disk is seen after it was detached (stale device), not why it comes back after rescan, which seems to suggest it is not detached properly. If I pass an API call to reboot, the VM reboots and the stale disks are still connected, however if I pass an API call to shutdown, the stale disks are removed. Is there something else that can be passed to the reboot API call to have it disconnect whatever the shutdown does? If not, is there a way to defer an API call as my backup VM is what is calling the API, it cant call to start itself if it is off due to a shutdown call?

Anyone have ideas about > either issue, I¹d love to hear ;) Same - logs would be helpful here. I will continue to dig through this issue and will post logs if stuck. I just wanted to know if there was anything obvious that I should be doing differently with iSCSI vs NFS with mounting disks/snapshots.

Re: [ovirt-users] how do you backup VM - Citrix Xen Migrate too!
Hi Peter, Have a look at my solution here. https://github.com/zipurman/oVIRT_Simple_Backup Is a full backup solution and a migration utility from Xen(Citrix) to oVirt.

Re: [ovirt-users] oVirt 4.2 WebUI Plugin API Docs?
Thanks Alexander,
This works:
api.addMainTab('oVirtTab', 'ovirt-tab', ‘http://www.something.com',
{priority: 5});
Can you advise how to get the api.addSubTab to work?
api.addSubTab('ovirt-tab', 'Test 123', 'test-123', '#’);
I tried the above and many other combinations, no errors, just doesnt work.
Maybe I am wrong on what it does?
I am looking to add a submenu – same as the current 4.2.1 UI shows Network
and then(Vnic Profiles) (Networks) as submenus.
Thanks

[ovirt-users] CORSFilter Web Admin
Is there a way to make CORSFilter work for webadmin? I have tried using the: engine-config -l | grep CORS engine-config -s CORSSupport=true engine-config -s CORSAllowedOrigins=* service ovirt-engine restart A look at: engine-config -l | grep CORS Looks like support is only for REST API? - CORSSupport: "Enables CORS (Cross Origin Resource Sharing) support in RESTAPI.² I have also tried adding to /usr/share/ovirt-engine/engine.ear/webadmin.war/WEB-INF/web.xml CORSSupport org.ovirt.engine.core.utils.servlet.CORSSupportFilter CORSSupport /* But that just ends up in Server Errors https://pastebin.com/Q1JECzSw Thanks for any help ;) Zip ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
