[ovirt-users] Snapshot chain inconsistency

2024-03-05 Thread Giulio Casella


Hi,
I encountered an issue in removing a snapshot. Trying to remove a 
snapshot of a VM with two disks I got an error in engine.log (and 
removal fails):


2024-03-05 15:23:10,568+01 ERROR 
[org.ovirt.engine.core.bll.MergeStatusCommand] 
(EE-ManagedExecutorService-commandCoordinator-Thread-1)

As I said VM has two disks, one of them is behaving correctly, the other 
one has some issue.


If I try (on the hypervisor):

vdsm-tool dump-volume-chains 

I get:

Virtual machine is (luckily) up and running.


Any hint to fix? Engine DB tweak?

Same here.

Furthermore Murphy's law says: "it will happen in the middle of your

[ovirt-users] Ovirt API: get guest current user

2023-11-22 Thread Giulio Casella


Hi,
is there a way to retrieve user currently logged in on a guest using API 
calls?
I see such information in database (specifically in vm_dynamic table), 
but nothing in API docs.


Any hints?

[ovirt-users] Re: Failing vm backup

2023-03-26 Thread Giulio Casella

Edit: solved!

Just as a future reference: maybe one of the backup was badly
interrupted by some external event, and vm bitmaps were broken. I
performed a full backup, and then also incremental backups are working.

Backups for other VMs are working correctly. What could it be? Somehow

I tried to migrate VM to other hypervisors, with no luck. Didn't tried
to move disks (two, one for the OS, one for data) to another data

The VM is working correctly, but Murphy's law states this machine is a

Any hint?

Is this the scenario you are facing now?

There is another question of why the snapshot removal failed
initially, and I did not get logs with this information (although it
could be due to network issues)

We've dome some tests with vProtect after the leatest Ovirt release
4.5.2.4-1.el8  but we still have problems with snapshots removal and
disks left in locked or illegal state.

To bring back a disk from illegal state we live migrate the disk(s) to
another data domain. After this the snapshots are back to legal and can
be removed from the UI. This is pratical only for VMs with small disks.
Sadly one of the VMs we have problems with has a 2.5Tb disk attached :(

Hope this get solved soon.

vProtect support tells us that the snapshot issues is in oVirt (true)

vProtect 5.1 and oVirt 4.5 is a no go solution. We are thinking going

    Hi folks,
    since some month I have an issue with snapshot removals (I have
    storware
    vprotect backup system, heavily using snapshots).
    After some time spent on a bugzilla
    (https://bugzilla.redhat.com/show_bug.cgi?id=1948599
    <https://bugzilla.redhat.com/show_bug.cgi?id=1948599>) we discovered
    that
    my issue is not depending on that bug :-(

    So they pointed me here again.

    Briefly: sometime snapshot removal fails, leaving snapshot in 
illegal
    state. Trying to remove again (via ovirt UI) keeps failing and 
doesn't
    solve. The only way to rebuild a consistent situation is live 
migrating

    affected disk to another storage domain; after moving the disk,
    snapshot
    is no more marked illegal and then I can remove it. You can imagine
    this
    is a bit tricky, specially for large disks.

    In my logs I can find:

Hi Giulio,

To get to the root cause of this problem, I think it is best to look at 
the engine and vdsm logs
from the initial failures with vprotect. You can open a new bug in BZ 
and place the relevant logs there.


Thanks,
Mark

Hi folks,

Briefly: sometime snapshot removal fails, leaving snapshot in illegal

[ovirt-users] Cannot deserialize - engine doesn't start

2022-07-13 Thread Giulio Casella


Hi guys,
I'm in big troubles.

Since last night my ovirt engine is unavailable (won't correctly start).
Process ovirt-engine is running, and systemd doesn't complain (systemctl 
status is ok).

Digging in engine.log I can find an error:

During the night there was a job that was moving a disk (2.5TB) from a 
storage domain to another. I think it's related.


Any ideas?

[ovirt-users] Unable to migrate VMs to a newly upgraded Ovirt node host

2021-12-16 Thread Giulio Casella


Hi guys,
I just faced a problem after updating a host. I cannot migrate VM to 
updated host.

Here's the error I see trying to migrate a VM to that host.

Dec 16 10:13:11 host01.ovn.di.unimi.it systemd[1]: Starting Network 
Manager Script Dispatcher Service...
Dec 16 10:13:11 host01.ovn.di.unimi.it libvirtd[5667]: Unable to read

file or directory

Dec 16 10:13:11 host01.ovn.xx.x.it kvm[35663]: 0 guests now active

Instead I can start VM on that host, and migrate away VM from that host.

Rolling back to ovirt-node-ng-4.4.9.1-0.20211207.0+1 via host console 
restores full functionality.


The affected version is ovirt-node-ng-4.4.9.3-0.20211215.0+1 (and also 
previous one, I don't remember precisely, it was another async release).



Any ideas?

[ovirt-users] ovrt node kernel

2021-07-07 Thread Giulio Casella

Hello everybody,
using ovirt node many of the drivers to access storage are not in the
kernel drivers (anymore).
For example I have a bunch of (old) hypervisors (50+), with infiniband
nics, used to access storage. For all those hypervisors I abandoned
ovirt node, in favor of a base CentOS stream distro, with ovirt repo and
using kernel-plus repo (conatining all the needed stuff).
Obviously this is not a step I liked, I definitely prefer ovirt node.

Now my proposal: why don't include kernel-plus in ovirt-node, instead of
traditional kernel?

I know this would be a big change, and maybe @Sandro and all RH guys
(they have a more general perspective) can see some drawback I don't,
but... hey, I just tried! :-)

Thank you in advance,
Giulio

Thanks Shani, this did the trick. I managed to tweak the database and
then correctly remove the snapshot.

In the meanwhile, in bugzilla

Ok, that is the relevant part of the output:

image:2fd9b340-14ce-42cd-a880-8f75eb3b72e7

   status: OK, voltype: LEAF, format: COW, legality: LEGAL,
type: SPARSE, capacity: 53687091200, truesize: 27917287424

So I have on storage two images, first one is a snapshot, second one is
Active VM.

Being the VM up and running I think I could say that on storage the
situation is consistent.

That's the point: engine (database) sees 3 images, whilst vdsm sees only 2.

And this is output of:

select
image_guid,parentid,imagestatus,vm_snapshot_id,volume_type,volume_format,active
from images where image_group_id='image-group-id';

  image_guid  |   parentid

So there is in the database an image (the one with image-guid
"6180c2e8-141a-4126-bcb1-5af5caa98175") not existing on storage.

I think it could not be enough, I think I should adjust parentship
relations in "images" table.

Just looking at that table it seems not so difficult, but: is it
sufficient? Is it safe?

[ovirt-users] Re: Cannot delete snapshot

2021-04-21 Thread Giulio Casella

I tried, with no luck. Giving "disk snapshot id" as a parameter to that
psql procedure nothing happened. Giving the "vm_snapshot_id" as found in
the "images" table made the snapshot disappear from the gui, but not
from the "images" table.

SO I decided to look into DeleteSnapshot procedure, that resolve as:

DELETE FROM snapshots WHERE snapshot_id = v_snapshot_id;

It only acts on the "snapshots" table, and not on the "image" table,
where the parentship between snapshots is still wrong.

How safe is to manually modify "images" table and set correct parentship?

Hi Nir,
in bugzilla I see it could be a bug, so I'm waiting for software update
to fix it.
In the meanwhile is there some fix I can do on the database? The VM is
working fine, but I cannot operate with snapshots, and my backup is stuck...

TIA,

[ovirt-users] Cannot delete snapshot

2021-04-12 Thread Giulio Casella

Hi,
I'm having (another) issue working with snapshots.

Since a few days my backup system (storware vprotect) cannot delete a
snapshot. Message reported by SPM is:

HSMGetAllTasksStatusesVDS failed: value=Volume does not exist:
('6180c2e8-141a-4126-bcb1-5af5caa98175',) abortedcode=201

Other snapshots from other VMs are working fine (created and deleted as
needed).

I verified it, I can reach on SPM filesystem other snapshots from the
same VM, but that one doesn't exist.

I suspect that during normal backup management that snapshot has been
correctly removed from file system, but still live in ovirt database.

I'm pretty sure vProtect use ovirt API to operate, it doesn't directly
interact with ovirt database. That's why I'm talking to you and not to
storware guys.

Is there a (safe) way to get rid of that snapshot?

TIA

2021-02-03 Thread Giulio Casella

Hi,
I tried unlock_entity.sh, and it solved the issue. So far so good.

But it's still unclear why disks were locked.

Let me make an hypothesis: in ovirt 4.3 a failure in snapshot removal
would lead to a snapshot in illegal status. No problem, you can remove
again and the situation is fixed.
In ovirt 4.4 a failure in snapshot removal leave the whole disk in
locked state (maybe a bug?), preventing any further action.

Does it make sense?

Hi Shani,
no tasks listed in UI, and now "taskcleaner.sh -o" reports no task (just
before I gave "taskcleaner.sh -r").
But disks are still locked, and "unlock_entity.sh -q -t all -c"
(accordingly) reports only two disk's uuid (with their vm's uuid).

Time to give a chance to unlock_entity.sh?

[ovirt-users] Locked disks

2021-02-03 Thread Giulio Casella

Since yesterday I found a couple VMs with locked disk. I don't know the
reason, I suspect some interaction made by our backup system (vprotect,
snapshot based), despite it's working for more than a year.

I'd give a chance to unlock_entity.sh script, but it reports:

CAUTION, this operation may lead to data corruption and should be used
with care. Please contact support prior to running this command

Do you think I should trust? Is it safe? VMs are in production...

it should. After a fresh CentOS install ("minimal install") I enable
Mellanox repo, dnf install mlnx-ofed-basic -y, and I can see ib0 device
(and I can get IP via DHCP for example).
I still didn't try to use real infiniband functionalities (in our
scenario NFS over IP over IB), but I'm quite confident about this.

[ovirt-users] ovirt node 4.4 and infiniband

2020-05-25 Thread Giulio Casella

Hi all,
I have in production a 4.3.9 setup of ovirt, based on a standalone
engine, not HE.
I have 3 datacenters (an 3 clusters). One of these clusters is composed
of many tenth of HP blades, accessing storage via InfiniBand (used as
normal NICs, via ipoib). They're not the state of the art, but I cannot
renew the entire hardware.

After a setup of ovirt node 4.4 I cannot see ib0 nic.

I managed to see it installing CentOS 8, enabling Mellanox repo
(https://linux.mellanox.com/public/repo/mlnx_ofed/latest/rhel8.1/mellanox_mlnx_ofed.repo)
and installing package "mlnx-ofed-basic".

In Ovirt Node it's not possible, that package require dependencies from
CentOS 8 repos, not present in ovirt repo.

Is there any chances to have infiniband NICs working in ovirt?

TIA,

[ovirt-users] Re: Bridge not forwarding frames on node.

2020-05-14 Thread Giulio Casella

Maybe you can check the vm network filter.
Take a look at Network -> vNic profile -> and
choose edit. If "Network Filter" has the default value
"vdsm-no-mac-spoofing", it can prevent bridge normal behaviour. Maybe
"No network filter" can do the magic.

HTH.

Hi to all!

I'm having an issue with networks bridges on ovirt node.

It's look like this bug:

On VM I have a bridge between a tap device and network interface.
On node side the interface is bridged with bond0 vlan 128

(bond0.128 lacp).

When I ping an host on the other side of tap device I can see this:

Arp request goes from my lan to the tap device on vm. Arp reply
return from tap vm and bridge forward this to vm networks
interface. Using tcpdump on vm interface on node I can see the arp
reply, using tcpdump on bond0.128 or on bridge I can't see the arp
reply. Arp request is forwarded from bond0.128 to vm net but arp
reply isn't forwarded from vm net to bond0.128.

Any chance that there is network filtering involved?
Please check if the related vNIC profile has No Network Filter.
If there is a Network Filter set, please shutdown the VM, set to No
Network Filter in the vNIC profile, and start the VM again and check
if the issue is gone.

Hi! No Network filter It was my first check.

[ovirt-users] Fedora 30 guest - kernel issue

2019-10-25 Thread Giulio Casella

Hi everybody,
yesterday I updated some of my fedora 30 ovirt guest, and after reboot I
wasn't able to control consoles via spice: I could see desktop, but
mouse and keyboard were not working (nor were key command in
remote-viewer menu, like ctrl-alt-F2 and so on).

Let me specify it's not strictly an ovirt issue, and the problem goes
away booting with old kernel (kernel-5.2.18-200.fc30.x86_64): the
problem arises only with fedora kernel version kernel-5.3.6-200.fc30.x86_64.

So: anyone has already faced this, before I dive into logfiles?

[ovirt-users] Re: Cloud Init static route

2019-10-09 Thread Giulio Casella

You can try adding something like this (taken from official cloud-init
docs):

network:
  version: 1
  config:
- type: route
  destination: 192.168.24.0/24
  gateway: 192.168.24.2
  metric: 2

to "custom script" field in the "initial run" section of the "Run once"
dialog.

Or in the analog part of the VM properties if you want to make it permanent.

In both cases cloud-init must be present (and automatically executed at
boot) in guest.

[ovirt-users] storware vProtect

2019-06-05 Thread Giulio Casella

Hi everyone,
I'm evaluating some datacenter backup solution, and finally I'm going to
give a chance to storware vprotect for my ovirt DC (2 clusters, 3+32
hypervisors, about 100+ VMs).

How many of you are using it? Any suggestion? Any caveat not immediately
visible? Hints? Drawbacks?

For example I have some problem mounting backup of some VM (pfsense
firewalls), based on UFS filesystem. And I couldn't browse mounted
backup from WebUI (NFS problems between server and node).
I know these are problems I can easily get around, but I'm more
concerned about issue I can't see right now.

[ovirt-users] VM info after upgrade to 4.3.2

2019-03-22 Thread Giulio Casella

Hi guys,
I noticed a strange behaviour after updating (part of) my setup to 4.3.2
(previously 4.3.1).
In detail I have the engine (stand alone, not hosted engine) version
4.3.2, and hosts (ovirt-node-ng) are 4.3.2 and 4.3.1.

In admin portal, VMs running on 4.3.2 hosts report incomplete
informations: some of them report no IP address and uptime, none of them
report memory, CPU and network usage.
Also a couple of VMs stay in "Powering up" state indefinitely
(nevertheless the VM is up and running). In this state I can't even
migrate the VM.

VMs running on 4.3.1 hosts, instead, are fine, reporting correct
informations.

For completeness: VMs are a mix of CentOS 7, Fedora, Windows 10, Windows
server, ..., with ovirt-guest-agent installed, but the OS seems to make
no difference.

Any ideas?

Correct. So the solution to use more than one ISO domain to logically
organize groups of ISOs cannot be accomplished, I'd like to see all my
ISOs at the same time.

That's why I think subfolders could be a nice enhancement for ISO
storage domains.

AFAIK you can have one ISO domain, one export domain and many data

"foo/bar.iso"), I'd expect to be able mount them.

I also filed a bug
(https://bugzilla.redhat.com/show_bug.cgi?id=1671046), if the answer
will be NOTABUG, I'll try with a RFE.

Thanks,
gc


TL;DR

The scenario I'm trying to implement is a DVD video store, provided by
images in ISO domain, automatically mounted on VM on demand, via a
backend python script. That's why in this case a hyerarchical structure
would be much better than a flat one.

[ovirt-users] Mounting ISO in subfolder

2019-01-30 Thread Giulio Casella

Hi,
I noticed that if I create a directory in root of ISO domain and put an
image in it, you can see it in admin portal image list (listed as
"foo/bar.iso"), but mounting that iso in a VM ("change CD") fails

"Error while executing action Change CD: Drive image file could not be
found"

I can easily reproduce this behaviour in ovirt 4.2.8 and rhv 4.2.7.

Is it a bug?

Cheers,

2018-11-14 Thread Giulio Casella

It's due to a update of collectd in epel, but ovirt repos contain also
collectd-write_http and collectd-disk (still not updated). We have to
wait for ovirt guys to release updated versions in
ovirt-4.2-centos-opstools repo.

I think it'll be a matter of few days.

[ovirt-users] Re: cloud-init behaviour after reboot and growpart

2018-10-23 Thread Giulio Casella

Maybe you can try disabling unused data sources. In /etc/cloud/cloud.cfg
of el7 vm:

datasource_list: ["NoCloud", "ConfigDrive"]

If I remember correctly ovirt use ConfigDrive to pass data to VM cloud-init.

Hope this helps.

[ovirt-users] IPoIB broken with ovirt 4.2.6

2018-09-03 Thread Giulio Casella

Hi,
latest ovirt node stable (4.2.6 today) introduced a bug in kernel: IP
over infiniband is not workingh anymore after an upgrade, due to kernel
3.10.0-862.11.6.el7.x86_64.

You can find some detail here:

https://bugs.centos.org/view.php?id=15193

dmesg is full of "failed to modify QP to RTR: -22", and the networking
stack (in my case used to connect to storage) is broken. The interface
can obtain an address via DHCP, but also a simple ICMP ping fails.

Does someone have news about a fix for this issue?

TIA,
Giulio

Fixed!
It was a problem independent from ovirt/ovirt agent.
It was a problem in writing to /var/run/utmp, causing /usr/bin/users 
(used by ovirt-guest-agent) to show an emtpy list of connected users.

OK, that makes sense. I think this is a bug in the server then. If the
users are not oVirt users we should just not report them, or maybe
report just the user name and domain, if available. But returning 404
and failing in that case isn't correct, in my opinion. I have opened the
following bug to track this issue:

  Don't fail with 404 if session user doesn't exist in the database

Great, thank you Juan.
My preference is for reporting username and domain, instead of not 
reporting at all.


Thank you again.

No problem, find attached a snippet of server.log.

Thanks, that helps. What the engine isn't finding is the user, not the
virtual machine. Can you provide more information about that user? I
mean, take the virtual machine and find via the GUI which user is using
it. Then go to https://.../ovirt-engine/api/users and find that user.
Share the definition of that user that you get there, if possible.

Giulio, you should never get a 404 error from that URL, unless the
virtual doesn't exist or isn't visible for you. What user name are
you
to create the SDK connection? An administrator or a regular user?



I tried with a regular domain user (with superuser role assigned) and
admin@internal, with same result.


Also, please check the /var/log/ovirt-engine/server.log and
/var/log/ovirt-engine/engine.log when you send that request. Do
you see
there something relevant?

Then share that log file so that we can check what the server is
returning exactly. Make sure to remove your password from that log
file
before sharing it.


Find attached produced log (passwords purged).

BTW: VM is a Fedora 24, with guest agents correctly installed (I

[ovirt-users] Desktop virtualization and thin clients

2017-04-04 Thread Giulio Casella


Hi,
I'm evaluating some thin client to connect to ovirt VMs, used as desktop 
workstations.
I really don't care about native client support, I distribute via PXE a 
custom linux OS launching remote viewer.

I'd like to have good multimedia performance, at a reasonable price.

Googling a little, I focused on a couple of vendor: https://www.igel.com 
and https://www.10zig.com/.


Anyone has already tested those vendor products? which model? which is 
the (approx.) price?

Obviously any hint on other vendors are welcome.

The scenario is composed of about 1500 VMs, running on ovirt (RHV to say 
the truth), distributed over 3 datacenters, currently accessed using old 
(5-7 years) PC, that I'm planning to renew.


TIA,
Giulio

[ovirt-users] ovirt 4 reboot behaviour

2017-01-17 Thread Giulio Casella


Hi,
I noticed a different behaviour after upgrading my entire setup from 
rhev 3.6.9 to rhev 4.0.5.
A virtual machine reboot changes the host where the VM is running, also 
if the VM was started in "run once" mode with a payload specifying a 
placement policy. In version 3 the VM didn't change host across a 
reboot; and continued running in run once mode, keeping the same payload 
given at start time.
Is there a way to keep the VM running on the same host across a reboot, 
excluding the obvious (but time consuming) way of migration after reboot?


If not (but this is a request for enhancement), is it possible to 
introduce a payload for reboot (just like for "start") to specify the 
placement policy?


Thank you in advance,

Hi Giulio,

Indeed it seems that there's an inconsistency between the storage and
the database.
Somehow the template's disk was removed from the storage. Your logs
don't tell how and when.

This is what needs to be done in order to get rid of the stale entries -
run in the database:

Delete from vm_device where device_id =
'6949d47a-0d38-468e-ad4e-670372841174';
Delete from images where image_group_id =
'6949d47a-0d38-468e-ad4e-670372841174';
Delete from base_disks where disk_id =
'6949d47a-0d38-468e-ad4e-670372841174';
Delete from vm_static where vm_guid =
'6ec76d42-98a6-4094-a76c-af1b639c5b30';


If it happens again, please file a BZ with the full logs of engine and

Feel free to ask anything if you got further questions.

The sysprep logic is only triggered once, the first time you start the

start it, basically repeat the steps that I suggested.


Yes, but the VMs belongs to a freshly created pool, never started before.


There were some bugs around this behaviour, some still not fixed in 3.5,
and it wasn't clear when the VM will use or not use sysprep, so we have
introduced a flag to explicitly force use of sysprep.

Please try to use this flag:

action = params.Action(use_sysprep=True)
vm.start(action)



Nice, use_sysprep=True did the trick!
I noticed also the flag use_cloud_init, I guess with same logic. I have 
to update my code accordingly.

Previously (ovirt 3.5) I directly wrote power management parameters into 
PowerManagement structure (and everything was working fine), but 
starting from 3.6 this is not possible.


This is what I do now:

agent = params.Agent()
agent.set_options(params.Options())
agent.set_type("ilo3")
agent.set_username("admin")
agent.set_password("mysecret")
agent.set_address("172.20.20.1")

agents=params.Agents()
agents.add_agent(agent)

pm=params.PowerManagement()
pm.set_agents(agents)
pm.set_enabled(True)

myhost=api.hosts.get("myhost")
myhost.set_power_management(pm)
try:
myhost.update()
except Exception as e:
print "Error: %s" % e

and I get:

Error:
status: 400
reason: Bad Request
detail: Cannot edit Host. Power Management is enabled for Host but no 
Agent type selected.



If I dont't enable PM (pm.set_enabled line above) I get no error, but no

Hi everybody,
I'm trying to enable power management on a host using python, but I'm stuck.

Previously (ovirt 3.5) I directly wrote power management parameters into
PowerManagement structure (and everything was working fine), but
starting from 3.6 this is not possible.

This is what I do now:

agent = params.Agent()
agent.set_options(params.Options())
agent.set_type("ilo3")
agent.set_username("admin")
agent.set_password("mysecret")
agent.set_address("172.20.20.1")

agents=params.Agents()
agents.add_agent(agent)

pm=params.PowerManagement()
pm.set_agents(agents)
pm.set_enabled(True)

myhost=api.hosts.get("myhost")
myhost.set_power_management(pm)
try:
myhost.update()
except Exception as e:
print "Error: %s" % e

and I get:

Error:
status: 400
reason: Bad Request
detail: Cannot edit Host. Power Management is enabled for Host but no
Agent type selected.


If I dont't enable PM (pm.set_enabled line above) I get no error, but no
agent is added.

In 3.6 fencing agents have been converted into a sub-collection of the
host entity:

   https://.../ovirt-engine/api/hosts/{host:id}/fenceagents

This means that the recommended way to add/remove/update fencing agents
now in Python is now this:

---8<---
# Find the host:
host = api.hosts.get(name="myhost");

# Enable power management:
host.get_power_management().set_enabled(True)
host.update()

# Add the fencing agent:
agent = params.Agent()
agent.set_options(params.Options())
agent.set_type("ilo3")
agent.set_username("admin")
agent.set_password("mysecret")
agent.set_address("172.20.20.1")
agent.set_order(1);
host.fenceagents.add(agent)
--->8---


This piece of code is working, thanks! But only if host.update() is 
called after adding an agent (e.g moving host.update() at the bottom). I 
don't have any fence agent configured before, and setting enabled=True 
and calling update, lead to the 400 HTTP error.




You can use this as a workaround. However the mechanism used in 3.5
should continue working in 3.6. If it doesn't it is a bug. The script
that you shared is the one you used in 3.5?



In 3.5 I used:

myhost=api.hosts.get("myhost")
pm=params.PowerManagement(type_="ilo3",enabled=True,address="172.20.20.1",username="admin",password="mysecret")
myhost.set_power_management(pm)
myhost.update()

not working in 3.6 (according to bug 
https://bugzilla.redhat.com/show_bug.cgi?id=1118329, marked CLOSED 
WONTFIX, there is no backward compatibility).


Anyway I reached my goal, thank you!

Is the operating system of the set to one of the Windows variants? If it

The problem is that using non persistent payloads isn't currently
supported, so basically your payloads element is silently
ignored. You
have currently two alternatives:

1. Use persistent payloads:

vm = vms.get(name=myvm)
vm.set_payloads(paylaods)
vm.update()
vm.start(params.Action())

You may also want to remove the payloads once the machine is
configured,
but this isn't strictly required, as Windows will not try to locate
the
sysprep floppy in subsequent boots. The only minor inconvenient is
that
the users of the VMs will see the floopy and its content attached.



Yes, this is exactly the workaround I'm currently using, and I have to
hide floppy via AD group policy (sysprep.inf contains administrator
password).


2. Use the builtin sysprep files (they are in
/usr/share/ovirt-engine/conf/sysprep):

vm = vms.get(name=myvm)
initialization = params.Initialization()
vm.set_initialization(initialization)
vm.update()
vm.start(params.Action())

This has the advantage that the sysprep floppy will be attached to the
VM only the first time it is booted. In subsequent boots it won't be
attached.



Great hint, I'll take a look into those syspreps to see if they fit for
my setup.


In 3.5 you will also be able to use sysprep support with your custom
file:

   vm = vms.get(name=myvm)
   initialization = params.Initialization(
 custom_script=The text of your sysprep file
   )
   vm.set_initialization(initialization)
   vm.update()

Thanks Juan,
this clearify a lot of things. So starting a VM is always a synchronous 
task in the backend, isn't it?
But in some condition (heavy load of hypervisors) this task takes long

Maybe I should submit a feature request...

The async parameter that you are passing to the REST API is only a
hint. It means that *if* the action performed by the backend has
associated async tasks then the REST API will not wait for them to
finish. In this particular case, the action performed by the backend
doesn't have async tasks, so the parameter is just ignored.
