Hey G!

If it was me doing this, I would make one 4x1Gb/s 802.3ad bond on filer and
hosts to KISS. Then, if bandwidth is of concern, I would set up two VLANs
for storage interfaces with addresses on separate subnets (10.0.0.1 and
10.0.1.1 on filer. 10.0.0.(2,3) and 10.0.1.(2,3) on hosts) and then on the
filer set up only two NFS exports where you try to as evenly as possible
provision your VMs. This way the network load would evenly spread over all
interfaces for simplest config and best fault tolerance, while keeping
storage traffic at max 2Gb/s. You only need one SVM with several addresses
to achieve this. We have our VMWare environment set up similar to this
towards our NetApp. We also have our oVirt environment set up like this,
but towards a different NFS storage, with great success.

Thanks for your answer, K!
So you mean to make a unique bond composed by all 4 network adapters and
put all the networks on it, comprised ovirtmgmt and such, through clans?
How do you configure 802.3ad on 4 adapters? How many switches do you have
to connect to, from these 4 adapters? Or do you use round robin bonding
(but I presume it is not supported in court this bond)?
Thanks!

There are two places you should look. One is vdsm.log on the host
performing the import. And if you have oVirt 4.1 another place to look
at is /var/log/vdsm/import where the import logs are stored.

Install virtio-win package somewhere. In it, inside
/usr/share/virtio-win directory, you will find virtio-win-*.iso file.

ok, we’re finally adding  headless VM option, but indeed for now you do not 
have any better choice for HE. But at least you do not really have to use it, 
right? You should be able to work with it over ssh.

Re: [ovirt-users] VNC console extremely slow on windows 10

2017-02-17 Thread Nelson Lameiras 
Yaniv, 

I've done some extensive investigation, and my conclusions so far bring some 
new light to this issue : 

As you have hinted, this is not a problem related to windows 10, as I was able 
to reproduce it with any laptop/system with windows 7 or 10. In fact, I do not 
find any evidence that VNC console works OK with any windows (maybe is our 
hardware?? => we use DELL). I'm not sure anymore it did work in the past... 

This is a problem related only with VNC consoles on virtual machines using 
windows client. SPICE works great under windows. VNC console works OK with 
remote viewer under centos. 

I found out something interesting : as I said, console is so slow that it 
bearebly useable (1 refresh every 10 seconds) but if I alt+tab twice (change 
focus off and on) it will refresh immediatly. This seems to me as a client 
issue... not a oVirt issue. So maybe I should take this issue with remote 
viewer team ? 

To answer your last question : "What oVirt installation needs VNC? " Indeed, 
oVirt hosted-engine installation needs a console and it proposes VNC and SPICE 
(vnc is default). SPICE console asks for a certificate configuration that I did 
not spent the necessary time to make it work as VNC works right out of the box 
(even if there is the refresh rate problem). 

any information or hint to find a solution would be appreciated. thanks

The API doesn't currently have a method to update a quota limit, so you
will have to remove the existing one and add a new one. For example, if
you want to change the storage quota of the 'mydata' storage domain to
100 GiB, you can do something like this:

---8<---
# Find the reference to the root of services:
system_service = connection.system_service()

# Find the data center and the service that manages it:
dcs_service = system_service.data_centers_service()
dc = dcs_service.list(search='name=mydc')[0]
dc_service = dcs_service.data_center_service(dc.id)

# Find the storage domain and the service that manages it:
sds_service = system_service.storage_domains_service()
sd = sds_service.list(search='name=mydata')[0]
sd_service = sds_service.storage_domain_service(sd.id)

# Find the quota and the service that manages it. Note that the service
# that manages the quota doesn't support search, so we need to retrieve
# all the quotas and filter explicitly. If the quota doesn't exist,
# create it.
quotas_service = dc_service.quotas_service()
quotas = quotas_service.list()
quota = next(
(q for q in quotas if q.name == 'myquota'),
None
)
if quota is None:
quota = quotas_service.add(
quota=types.Quota(
name='myquota',
description='My quota',
cluster_hard_limit_pct=20,
cluster_soft_limit_pct=80,
storage_hard_limit_pct=20,
storage_soft_limit_pct=80
)
)
quota_service = quotas_service.quota_service(quota.id)

# Find the quota limits for the storage domain that we are interested
# on. If that limit exists we will delete it, and create it again with
# the desired limit, in this example it will be 100 GiB.
limits_service = quota_service.quota_storage_limits_service()
limits = limits_service.list()
limit = next(
(l for l in limits if l.id == sd.id),
None
)
if limit is not None:
limit_service = limits_service.limit_service(limit.id)
limit_service.remove()
limit = limits_service.add(
limit=types.QuotaStorageLimit(
name='mydatalimit',
description='My storage domain limit',
limit=100,
storage_domain=types.StorageDomain(
id=sd.id

[ovirt-users] How to manage to update the Quota limits parameters (cpu, memory and disk)

2017-02-17 Thread Manuel Luis Aznar 
Hello there,

I want to update the quota limit parameters for vcpu, memory and disk, but
I dont find the way.

I manage to get the actual values but I am unable to manage how to update
this values.

I am doing the following (I ommit the imports and conection stuff):

  system_service = connection.system_service()

  data_centers_service = system_service.data_centers_service()

  data_center = data_centers_service.list(search='name=Prueba2')[0]

  data_center_service = data_centers_service.data_center_service(id=
data_center.id)

  quotas_service = data_center_service.quotas_service()

  quota = quotas_service.list()[0]

  quota_service = quotas_service.quota_service(id=quota.id)

  quota_cluster_limits_service =
quota_service.quota_cluster_limits_service()

  quotaclusterlimit = quota_cluster_limits_service.list()[0]

  quota_storage_limits_service =
quota_service.quota_storage_limits_service()

quotastoragelimit = quota_storage_limits_service.list()[0]

if after that I print the following:
  quotaclusterlimit.memory_limit
  quotaclusterlimit.vcpu_limit
  quotastoragelimit.limit

i see the actual values of the limits, but, I m not able to update that
values (I have been testing on how to do it). It seems that the only method
that let you update anything on a quota is using:

   quota_service.add(quota=...)

I start creating a new quota object with these new limits by doing the
following:

  new_quotastoragelimit = ovirtsdk4.types.QuotaStorageLimit(limit=100)
  new_quotaclusterlimit =
ovirtsdk4.types.QuotaClusterLimit(memory_limit=100,vcpu_limit=10)

  new_quota =
ovirtsdk4.types.Quota(quota_cluster_limits=new_quotaclusterlimit,
quota_storage_limits=new_quotastoragelimit)

  quota_service.update(quota=new_quota)

I have directly tried to edit the printed values directly and then doing
the update but I got nothing (got event in the engine but the limit did not
change)

  quotaclusterlimit.memory_limit =100
  quotaclusterlimit.vcpu_limit = 10
  quotastoragelimit.limit = 100
  quota_service.update(quota=quota) # updating quota with itself

I suppose that there would be a way on how to this, so if you can help, i
will really appreciate you.

Thanks for all in advance to all

Re: [ovirt-users] VMs are not running/booting on one host

2017-02-17 Thread Peter Hudec 
As I'm deeping into the problem, your is described here

o   Booting Linux using a console connection that is too slow to
keep up with the boot-time console-message rate.  For example,
a 115Kbaud serial console can be -way- too slow to keep up
with boot-time message rates, and will frequently result in
RCU CPU stall warning messages.  Especially if you have added
debug printk()s.

no, not in case of user initiated shutdown. The feature is intended to 
unplanned poweroffs, crashes and such.

[ovirt-users] HA and poweroff of VM

2017-02-17 Thread Gianluca Cecchi 
Hello,
after setting a VM as HA I run poweroff from inside the VM.
Is it supposed to be automatically restarted in this scenario with oVirt
4.1?

In engine I see:

VM c7service is down. Exit message: User shut down from within the guest

Apparently no restart

How to test eventually HA functionality?
Tanks,
Gianluca

Re: [ovirt-users] Change Vlan ID's which are connected to the Host/VM's

2017-02-17 Thread Matt . 
OK, I just found out that it's not possible to change the network name
when the network is attached to VM's as well. I wonder why that is
because for VM's it's only DB stuff being done.

Can't this be changed ?

Thanks,

Matt

Can you please test the fix?

# yum install centos-release-qemu-ev
# yum-config-manager --enable centos-qemu-ev-test
# yum update
