Yes, this is the correct option.

But note that deleting an image on nfs means 3 unlink operations per volume.
If you have an image with one snapshot, that means 2 volumes, and 6
unlink calls.

If unlink takes 70 seconds (timing out with current 60 seconds
timeout), deleting
the image with one snaphost will take 420 seconds.

On the engine side, engine wait until deleteImage finish, or until vdsTimeout
expired (by default 180 seconds), so you may need to increase the engine
timeout as well.

While engine wait for deleteImage to finish, no other spm operation can run.

So increasing the timeout is not the correct solution. You should check why your
storage needs more then 60 seconds to perform unlink operation and change
your setup so unlink works in a timely manner.

As a start, it would be useful to see the results of nfsstat on the
host experiencing
the slow deletes.

In master we perform now the delteImage operation in a background task, so
slow unlink should not effect the engine side, and you can increase
process_pool_timeout
as needed.
See 
https://github.com/oVirt/vdsm/commit/3239e74d1a9087352fca454926224f47272da6c5

We don't plan to backport this change to 3.6 since it is risky and
does not fix the root
cause, which is the slow nfs server, but if you want to test it, I can
make a patch for 3.6.

Well it will increase the time to 3 minutes and takes effect after restarting 
vdsm and supervdsm - If that is enough that might depend on your setup.

Well I might be wrong, but from what I can see that is the right value to

Thanks Vinzenz,

maybe my question was not 100% correct. I need to know, if this parameter 
really influences the described timeout behaviour. The best value of the

[ovirt-users] Still not possible to resize hosted engine disk?

Hi, I'm using 3.6.2 pre and using hosted engine over iscsi. The 
appliance provisioned a 10GB virtual disk, even if the LUN is 100GB. How 
can I extend the vm disk? From the gui it doesn't seem to be possible

Hi,

What I did from the beginning of this affair :

2)  Don’t try to run it from shell


3)  Up to now,  I may avoid to play with custom properties.
( BTW,  do you know how , within myhook.py , one may retrieve this custom 
property
   that will indicate if the hook has to be go further or must exist without 
doing anything ?)

What’s remaining :

1) debug the .py
2) check wether, by migrating the Guest , the hook is also called on the target 
host  ( maybe you know the answer ?)

That’s all.

Hi, 

There aren't too many thin clients out there which support oVirt/RHEV. 

I did a few VDI projects with oVirt and RHEV and I can recommend the Igel UD5 
Thin Client: 
https://www.igel.com/en/products/igel-thin-clients/ud5-series.html 

It's not the cheapest one and not the smallest one, but has good performance 
and the management software for these thin clients is great.

This is documented on the hooks wiki page and in github. The basic idea is to 
add a custom property to a VM with specific text, and check for it in the hook. 
If you detect it, apply hook to VM, if not - pass

1) debug the .py
2) check wether, by migrating the Guest , the hook is also called on the target 
host  ( maybe you know the answer ?)

before_vm_migrate_source and before_vm_migrate_destination - also documented in 
the wiki.

Generally, just follow an existing hook, it should have everything

That’s all.

Hi Nathanaël,

Are you looking for specific information?
The planning is, as always has been, in Bugzilla and while many work
on 3.6.x still, there has been some work on 4.0 items already (mainly
in the mast branch of oVirt).
I'm using [1] as a Bugzilla query to look at all open RFEs. Those with
4.0.0 are the ones currently targeted for 4.0 - but I assume more will
be added/removed to the list.

Which meetings and reports are you missing?

I've just restarted libvirtd on all nodes and now it seems to work

Libvirt is the latest from RH7.2 update and qemu-kvm-ev from ovirt repo.

Is the NFS connection healthy (can be seen with nfsstat)
Generally, delete on NFS should be a pretty quick operation.

Hi Yaniv,

we usually have no problems with our NFS server. From our observations we 
only have issues when deleting files with many extents. This applies to all 
OVirt images files. Several of them have more than 50.000 extents, a few 
even more than 300.000.

Our XFS is mounted with:

/dev/mapper/vg00-lvdata on /var/nas4 type xfs 
(rw,noatime,nodiratime,allocsize=16m)

Why we use allocsize=16M? We once started with allocize=512MB. This
led to sparse files that did not save much bytes. Because a single byte written
resulted in a 512MB allocation. Thin allocation of these files resulted in long 
runtimes
for formatting disks inside the VMS. So we reduced to 16MB as a balanced config

This works quite well but not for remove operations.

Better ideas?

[ovirt-users] vdsm hook issues

Hi,

1)  is it enough to add a hook.py in  /usr/libexec/vdsm/hooks/before_vm_start 
directory , and then shut down and reboot a guest to
see this hook.py invoked ?

2) when running manually my hook.py, I got following error :
 ImportError: No module named hooking

Do I have to install anything to solve this issue ?

Thanks for help.

So, to make is work, you need to chown 36:36 and chmod +x for 36:36 of course.

As for logging, since the hook is run under the vdsm context, you can tap right 
into the logging of vdsm, or you can write your own log file, whatever you 
prefer to code.

See 
https://github.com/oVirt/vdsm/blob/master/vdsm_hooks/vmfex/before_vm_start.py 
line 197 - sys.stderr.write will actually dump into the vdsm log.

yup. Now add the sys.stderr.write line somewhere, with a marker you can
grep for, and try, then check the vdsm.log file for the marker. I'd also
add an external log dump for the development testing, and comment it out
before going into production

Which DC are you trying to attach the Storage Domain?
From the attached print screens it looks like the DC you have permissions on 
are infra and local.
Also, Which oVirt version are you using?
If it is possible can you please send print screens with the permissions of the 
user and the permissions on the Data Center?

Thanks,

Re: [ovirt-users] vdsm hook issues

2016-01-12 Thread Dan Yasny

OK, so the hooking module is included in the vdsm package itself. Please
make sure you have /usr/share/vdsm/hooking.py on the host.

The manual run fails, because it is not running in the vdsm context, and so
the modules imported are the python site-packages and not the submodules
under vdsm.

To make a hook work, you need to place it on the host, make it accessible
to vdsm:kvm, and maybe define a custom property, if you don't want the hook
to just run on every started VM.

[ovirt-users] Ovirt supported thinclient appliance

2016-01-12 Thread RK RK

Hi all,

I am planning to setup oVirt 3.6.1 Virtualization setup for 100 desktop
users in my software development company.

Anyone please suggest me a good and cost-effective thinclient
appliance(available in india) to use with my oVirt environment with support
for SPICE protocol.

Re: [ovirt-users] vdsm hook issues

2016-01-12 Thread Dan Yasny

So, to make is work, you need to chown 36:36 and chmod +x for 36:36 of
course.

As for logging, since the hook is run under the vdsm context, you can tap
right into the logging of vdsm, or you can write your own log file,
whatever you prefer to code.

See
https://github.com/oVirt/vdsm/blob/master/vdsm_hooks/vmfex/before_vm_start.py
line 197 - sys.stderr.write will actually dump into the vdsm log.

Re: [ovirt-users] vdsm hook issues

2016-01-12 Thread Jean-Pierre Ribeauville

Hi,

/usr/share/vdsm/hooking.py  is present on my host.

I placed my test_hook.py  in /usr/libexec/vdsm/hooks/before_vm_start

As I want to have it invoked for every started VM ,  I don’t need custom 
property ; Am I right ?

Remains the point “make it accessible to vdsm:kvm”  what do you mean ?

BTW , are vdsm hooks log infos located in /var/log/vdsm/vdsm.log  ?

Thx for help.

OK, so the hooking module is included in the vdsm package itself. Please make 
sure you have /usr/share/vdsm/hooking.py on the host.

The manual run fails, because it is not running in the vdsm context, and so the 
modules imported are the python site-packages and not the submodules under vdsm.

To make a hook work, you need to place it on the host, make it accessible to 
vdsm:kvm, and maybe define a custom property, if you don't want the hook to 
just run on every started VM.

[ovirt-users] API Importing a VM from an export domain fails

2016-01-12 Thread Tim Bielawa

Hello virt folks,

Background:

I'm using the REST API to import a VM from an attached export domain. The
VM was imported using the virt-v2v tool. I've tried this with cURL and with
the python SDK, both yield the same error message.

RHEVM Version: 3.5.6.0-1
Python SDK Version: 3.5.6.0-1

According to the documentation, importing should follow this syntax:

> POST /ovirt-engine
/api/storagedomains/{storagedomain:id}/vms/{vm:id}/import

With a small  body attached. In theory (by the documentation and
bug tracker [1]) either of these XML documents (both in the same paste)
should work:

http://fpaste.org/309944/52627148/

However, this fails with the following error message (full response in [2])

> Cannot import VM. Storage Domain type not specified.


Steps to reproduce:

1. Import a VM into an export storage domain
2. Create an XML document with an action like this (filling in the correct
values for the ID variables)


>   
>   
> export
>   
>   True
>   
> IMPORTED_VM
>   
> 


3. POST to the import location (again, substitute the correct ID variables
in the location)

/ovirt-engine/api/storagedomains//vms//import



Where is this storage domain type supposed to be defined, if not inside of
the storage_domain element as demonstrated in the documentation?

I would appreciate any advice you can offer or pointers to useful
resources/documentation.

Thanks!

This is documented on the hooks wiki page and in github. The basic idea is
to add a custom property to a VM with specific text, and check for it in
the hook. If you detect it, apply hook to VM, if not - pass

before_vm_migrate_source and before_vm_migrate_destination - also
documented in the wiki.

Generally, just follow an existing hook, it should have everything
