Host needs to be reinstalled after configuring power management
by Andrew DeMaria
Hi,
I am running ovirt 4.3 and have found the following action item immediately
after configuring power management for a host:
Host needs to be reinstalled as important configuration changes were
applied on it.
The thing is - I've just freshly installed this host and it seems strange
that I need to reinstall it.
Is there a better way to install a host and configure power management
without having to reinstall it after?
Thanks,
Andrew

migration infinite loop
by Renaud RAKOTOMALALA
Hi,
I switch an host in "PreparingForMaintenance" state to prepare an
upgrade. In this stage the host migrating all VM but failed on one due
to a network's congestion.
Because the host try to migrate this VM and the constant failure of
the migration, we enter in an infinite loop.
How can I stop this loop ? I’m not able to cancel the mainteance mode
with the WebUI.
Any idea ?
Thanks

Cinderlib RBD ceph template issues
by Sketch
This is on oVirt 4.4.8, engine on CS8, hosts on C8, cluster and DC are
both set to 4.6.
With a newly configured cinderlib/ceph RBD setup. I can create new VM
images, and copy existing VM images, but I can't copy existing template
images to RBD. When I do, I try, I get this error in cinderlib.log (see
below), which sounds like the disk already exists there, but it definitely
does not. This leaves me unable to create new VMs on RBD, only migrate
existing VM disks.

no snaphot but engines complains there is one when trying to remove disk
by Nathanaël Blanchet
Hi all,
A colleague launched this morning a snapshot creation, there was no
error message but he wasn't able to start the vm anymore, with this
issue : VM PSI-SYB-DEV is down with error. Exit message: Unable to get
volume size for domain a5be6cae-f0c8-452f-b7cd-70d0e5eed710 volume
109fac1e-c2e3-4ba6-9867-5d1c94d3a447..
I tried many things but nothing works: it is impossible to remove this
disk, or copy it, or clone the vm :
Cannot detach Virtual Disk. The disk is already configured in a
snapshot. In order to detach it, remove the disk's snapshots.
There is no snaphost listed into webui or api (so not snapshot id),
while disk_snapshots exists into the associated storage domain.
So I tried to remove disks snapshot direvctly with API followind the
DELETE method
|DELETE /api/storagedomains/{storage_id}/disksnapshots/{image_id}|
[Cannot remove Disk Snapshot. VM\'s Snapshot does not exist.]
In conclusion: vm_disks can't be removed because of the non existent
associated vm's snapshot id.
I tried to remove vm_snapshots disks references directly into the
postgres DB but I didn't find the correct table.
What can I do now?
Your precious help is welcome.
