Is this on the roadmap?
I just bought a bunch of 4k native drives and spent a LOT of money. Now
it seems they are useless in my oVirt/RHEV environment...

python sdk v3 host nic issues
by Huan He (huhe)
Hi,
I tried the host nic and bond sample code in http://www.ovirt.org/develop/api/pythonapi/. In gui, I am able to create bond and vlan network without issues.
here is my code
if __name__ == '__main__':
url = 'https://huhe-rhev-m.cisco.com/ovirt-engine/api'
usr = 'admin@internal'
pwd = 'nbv12345'
ca_file = '/home/huhe/workspace/ansible/crt/ca.der'
api = API(url=url, username=usr, password=pwd, ca_file=ca_file, debug=True)
print api.get_product_info().name
nic0 = params.HostNIC(name = 'enp6s0', network = params.Network(), boot_protocol='none', ip=params.IP(address='', netmask='', gateway=''))
nic1 = params.HostNIC(name = 'enp7s0', network = params.Network(), boot_protocol='none', ip=params.IP(address='', netmask='', gateway=''))
nic2 = params.HostNIC(name = 'enp8s0', network = params.Network(), boot_protocol='none', ip=params.IP(address='', netmask='', gateway=''))
nic3 = params.HostNIC(name = 'enp9s0', network = params.Network(), boot_protocol='none', ip=params.IP(address='', netmask='', gateway=''))
bond = params.Bonding(
slaves = params.Slaves(host_nic = [ nic0, nic1, nic2, nic3 ]),
options = params.Options(
option = [
params.Option(name = 'miimon', value = '100'),
params.Option(name = 'mode', value = '1'),
params.Option(name = 'primary', value = 'enp6s0')]
)
)
managementNetwork = params.HostNIC(network = params.Network(name = 'ovirtmgmt'),
name = 'bond0',

override_configuration = 1,
bonding = bond)
networkName = 'my_vm_db'
clusterNetwork = api.clusters.get('my_cluster').networks.get(name = networkName)
vlanNetwork = params.HostNIC(network = params.Network(name = networkName), name = "bond0.%s" % clusterNetwork.vlan.id)
host = api.hosts.get('host-172')
host.nics.setupnetworks(params.Action(force = 0,

VM storage issue after snapshot deletion
by Ollie Armstrong
Hi everyone.
I'm having an issue with a VM after initiating a snapshot deletion.
Shortly after the deletion started the VM was paused and has not
recovered since, this was over 12 hours ago.
I've dug into the logs and here's some things that jumped out at me:
engine.log
Message: VM XXXXXX has been paused due to unknown storage error.
vdsm.log
Improbable extension request for volume
cb180795-1da8-4a4c-90a9-b42d00485018 on domain
0243ebd9-fd3f-4674-b4e7-05af734280e7, pausing the VM to avoid
corruptions (capacity: 53687091200, allocated: 5750586880, physical:
1073741824, next physical size: 2147483648)
The vdsm.log line I've quoted is repeated approximately every 2
seconds from the first occurrence and is still going. I've attached
engine.log and uploaded vdsm.log to my server [1] as it was 10M. The
VM in question has the ID 184f89f4-8427-4a28-8787-8912f5c5f038.
The VM is still paused and cannot be resumed, seemingly as a
precaution to avoid corruption.
Is there anything I can do to recover the data on the disk? All help
is greatly appreciated.
I'm running oVirt 3.6.6.2-1 on CentOS 7.
Cheers,
Ollie

Missing engine-manage-domains?!

No VMs to import
by Frank Rothenstein
Hello,
now that gluster 3.7.14 is out I was able to change the storage domains
mount from NFS back to GlusterFS. The first domain worked flawlessly
this way:
set domain to maintenance -> detach -> remove -> import Domain (this
time GlusterFS) -> import VMs
The other storage domain works too, but in the gui is no tab Import VMs
or Import Disks.
Is there any other way to rescan/reimport VMs on this storage domain?
Frank

hosted_engine on gluster storage for all the same fqdn?
by Florian Nolden
Hi,
I try to install the hosted_engine on 3 Servers which host also the gluster
data storage.
When I install now the hosted_engine, which storage path should I use?
Setup 1:
server1: server1.san:/hosted_engine
server2: server1.san:/hosted_engine
server3: server1.san:/hosted_engine
Setup 2:
server1: localhost:/hosted_engine
server2: localhost:/hosted_engine
server3: localhost:/hosted_engine
Setup 3:
/etc/hosts: 127.0.0.1 gluster
server1: gluster:/hosted_engine
server2: gluster:/hosted_engine
server3: gluster:/hosted_engine
Other Setup? What is the best practice there?

Multipath iSCSI with several IPs
by James Michels
Hello,
I want to add an iSCSI based storage domain. For that I add a domain on the
Storage tab with one of the IPs (say 10.10.10.1), but for failover purposes
I'd like to use multipath to add a failover IP so if the first one fails,
LUNs can be reached via the second (say 10.10.10.2).
How can this be done in oVirt 4.0.1? I have not seen a way how to add the
second IP for multipath purposes.
Thank you
James
