Python API question
by Colin Coe 16 Jan '16

16 Jan '16

Hi all I've written a Python script to take nightly snapshots of VMs which are kept for x days. After x days the snapshot is deleted. I can't work out how to wait for the snapshot deletion to complete. I know how to do it for creating the snapshot but I've not been able to get it right for the deletion. api.vms.get(VM_NAME).snapshots.add(params.Snapshot(description=SNAPSHOT_NAME, vm=api.vms.get(VM_NAME), persist_memorystate=True)) while api.vms.get(VM_NAME).status.state == 'image_locked': sleep(1) Any ideas? Thanks CC

Default profile
by Colin Coe 16 Jan '16

16 Jan '16

Hi all Is it possible to set the default profile (on the User Portal login page and for all users) to the AD domain name rather than "Internal"? Also, can the "Connect Automatically" check box (on the User Portal login page) be set to default to un-checked? Running RHEV 3.5 Thanks CC

Network interface profiles disappeared after upgrading to 3.6.1
by nicolas＠devels.es 15 Jan '16

15 Jan '16

Hi, We recently upgraded from 3.5.3 to 3.6.1. Everything went fairly smooth, however, today we realized we're facing some issues. Users cannot add network interfaces on the User Portal to their VMs. It seems that when they click on "New", the "Profile" checkbox is empty so they cannot choose any value. It's worth mentioning that we only upgraded the manager, not yet the hosts. Also, a red banner keeps popping out every few seconds with this error: (TypeError) __gwt$exception: <skipped>: Cannot read property 'r' of null It's also worth mentioning that I can add interfaces from the admin portal. I don't actually know if it's related, but in the logs I see this: 2016-01-15 17:53:35,241 ERROR [org.ovirt.engine.core.bll.GetConfigurationValueQuery] (default task-165) [] Query execution failed due to insufficient permissions. 2016-01-15 17:53:35,241 ERROR [org.ovirt.engine.api.restapi.resource.AbstractBackendResource] (default task-165) [] Operation Failed: query execution failed due to insufficient permissions. All interfaces have the "Everyone" -> "UserProfileEditor" permission. Is that some new permission that has to be granted in order to allow users see the network interfaces or is it a bug? Thanks. Nicolás

Well you can look how we do it in the ovirt-guest-agent. But we?re not reop= ening the unix domain socket - We?re basically on read failure just resched= uling the read - That causes no problems after migrations - it just continu= es Our python code for that is here: https://github.com/oVirt/ovirt-guest-agen= t/blob/master/ovirt-guest-agent/VirtIoChannel.py HTH > > Any hint is welcome . > > Thanks for help. > > > J.P.

What's going on open channel devices when migrating the Guest ?

--_000_1051EFB4D3A1704680C38CCAAC5836D292F028AEWPTXMAIL2ptxaxw_ Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Hi, I'm using a channel device between host and guest to exchange datas every 2= 0 seconds. On the Guest size , there is an open /dev/virtio file on which we read cont= inuously what's sent by the host. My question is the following : When migrating the Guest to another host , and the migrating back to the f= irst one , the Guest software doesn't receive anymore datas from the host unless I res= tart the Guest software to re-open the /dev/virtio file. Is there any way to detect in the Guest that migration has been done so we = have to reopen the file ? Any hint is welcome . Thanks for help. J.P. Ribeauville P: +33.(0).1.47.17.20.49 .

ISO Domain: How to delete an ISO
by gregor 14 Jan '16

Hi, how can I delete an ISO from the ISO Domain? There are no hints in the documentation. I found only a restricted page for RedHat Customers only, but it isn't sure if there is really a solution. Hopefully somebody can help, this can't be such a secret. regards gregor
