Re: [ovirt-users] Hosted engine already imported

[Jamie Lawrence]

I’m wondering if I can do this a different way. Since it is already imported, I 
can create VMs, and the only other warning I’m getting in the logs is 
unrelated, I’m thinking that the problem here is that something didn’t get 
properly set in the DB, and I should be able to fix that manually.

In looking at the code 
(https://github.com/oVirt/ovirt-engine/blob/master/backend/manager/modules/bll/src/main/java/org/ovirt/engine/core/bll/storage/domain/ImportHostedEngineStorageDomainCommand.java),
 it to my (not very deep) read that the setSucceeded call failed, even though 
AttachStorageDomainToPool worked.

  if (getSucceeded()) {
AttachStorageDomainToPoolParameters attachSdParams =
new AttachStorageDomainToPoolParameters(
addSdParams.getStorageDomainId(),
addSdParams.getStoragePoolId());
setSucceeded(getBackend().runInternalAction(
VdcActionType.AttachStorageDomainToPool,
attachSdParams,
getContext()).getSucceeded());
}

setActionReturnValue(heStorageDomain);
 
Is there a way to call setSucceeded without hacking together a custom utility? 
Not seeing it in vdsClient --help, which doesn’t surprise me. In looking over 
the stored procedures, I’m also not finding a likely candidate, but that is 
probably because there are so many that I’m just missing it.

Does anyone know what the relevant SP is, or in some other way clue me in on 
the right direction here?  

I realize this is not supposed to be the way to do things. But I’m not finding 
a better solution, and attempting to find a “right” way via questions to this 
isn’t working either. And of course I take full responsibility when Ovirt  
kills my pets and drinks all my liquor.

Thank you Barak !

I will position Bacchus as a protection solution, not only for backups but
also replication. SDK would be a better decision in that way.

[ovirt-users] Trouble Adding Gluster Host in oVirt Manager

[Langley, Robert]

Hello oVirt Community,

This may be my first time writing in. Although, I've been reviewing and playing 
with oVirt for the past 3 years. My name is Robert Langley and I work for a 
local Government in Southern California. My agency (with me as the primary/lead 
IT person) has been using VMWare vSphere to host our server environment for 6 
years. I have a few different reasons I want to jump the VMWare ship and I've 
been pleased with the progression oVirt has been making. I do not care to jump 
from VMWare to Microsoft's Hyper-V, so this had lead me to look into Xen for a 
while, then dropped anchor with oVirt. I'm determined to see this 
implementation through.

I have moved over from the test (workstation class) environment, where I was 
really just getting familiar with the commands and UI, and now I am working on 
implementation with server class hardware.
I have the engine up and running. I'll get into more specifics below.
I'm running into an issue where I have not been able to add my Gluster hosts or 
add the Storage Domain (I had tried adding the storage domain first).
For my new oVirt and GlusterFS hosts I have the following:
*   I want to first mention that I do have a DNS server for the 
separated/private networks and those are configured and working properly 
(forward & reverse).
Dell PE R830 and I would like this to be a failover server housed in a separate 
building where we have an Emergency Operations Center and Datacenter (server 
room).
-   Has bonded gigabit (2 port) network that is connected to our main 
network & internet, configured to be used for ovirtmgnt. Name = gsaov08.ent...
o   As far as all the various names, oVirt Hosted Engine Deployment 
complained that the Main network name was seen on more than one interface, or 
something to that effect.
o   I did originally have DNS for the separated/private networks configured 
for forwarding DNS from our main network DNS servers. Which has been removed 
and the Hosted Engine Deployment stopped complaining at that point. I was going 
to use the forwarding DNS for another private network I use for some management 
traffic, but that is not as important or an absolute need either.
-   Has 2nd bonded gigabit (4 port) network (separate/private) for engine 
storage. Name = gsaov08e.engine.local
-   Has 3rd bonded 10G (2 port) network (separate/private) for VM Guest 
storage. Name = gsaov08s.stor.local
-   Will have a 4th network (separate/private) configured for security 
related devices that are managed by a couple of our VM guests.
As far as storage in this same server.
-   I have split up the local storage to be hosted by GlusterFS and this 
host is a peer with the other two dedicated GlusterFS storage servers. That is 
for the failover piece.
o   Engine volume (currently being used for the Hosted Engine) and setup as 
a replica 3 with the two dedicated GlusterFS storage servers.
o   VM Guest "Data" volume. The volume is created, configured and started. 
Setup as a replica 3 with the two dedicated GlusterFS storage servers.
So far, this is the only host I have hosting the engine. Now, onto the other 
host I am about to run Hosted-Engine -Deploy on.
Dell PE R730 - It has the same network setup as the R830. Storage is a bit 
different. I would like to run another VM Guest GlusterFS volume from here, 
along with 2 other hosts I have. They are currently serving as the vSphere ESX 
hosts and have the same total size of storage to create another replica 3.

The Dedicated GlusterFS Hosts are custom AMD Opteron G2 builds with ASUS server 
motherboards. Strictly designed to be dedicated storage servers.
-   I'm using the onboard NICs to connect to my management network only for 
the purpose of getting updates. So, internet is served to these hosts via a NAT 
router. Since I figured they don't otherwise need access to our main network. 
The primary names = gsa-stor1 & gsa-stor2
-   They both have a bonded (4 port) gigabit network for the Engine storage 
network. Names = gsa-stor1e.engine.local & gsa-stor2e.engine.local
-   They both have a bonded (2 port) 10G network for the VM Guest storage 
network. Names = gsa-stor2s.stor.local & gsa-stor2s.stor.local
As far as storage in these servers.
-   It is the same as the R830, as these servers are the peers to the R830.

First, I added an ISO Storage Domain (NFS). That was successful. Next, I was 
trying to add the GlusterFS VM Guest Data Storage Domain. I receive an 
Operation Canceled: Error while executing action AddGlusterFsStorageDomain: 
Error creating a storage domain.
When I try to add the Gluster hosts as hosts in the oVirt Manager, I get a 
message stating that SSH has failed, verify that the host is reachable (IP 
address, routable address etc.) You may refer to the engine.log file for 
further details.
I can otherwise communicate with the hosts and the engine.log does not appear 
to have specifics to this particular failure.

Well, it was made specifically to make building backup tools easier. But
I guess its up to you to decide if it helps you or not.
I'm not sure, but maybe the SDK supports it as well.

In any case, great work!

Hi Barak,

I was not aware of backup api hence used Python SDK. Is there any specific
reason that I should use the backup api ?



ps. I have just deployed the demo system at http://demo.bacchus.co

It was imported automatically. The chain of events was install HE, wait for the 
emails saying it was done cogitating, create the regular Gluster SD, import it. 
Shortly thereafter, the HE domain was imported, and things (storage, hosts, 
clusters) all appear correct in the GUI, but the error persists.

Re: [ovirt-users] Ovirt 4, the missing python sdk

[Ben De Luca]

ok this works.

docker run --rm -v ${PWD}:/local swaggerapi/swagger-codegen-cli generate \
-i /local/swagger.json \
-c /local/config.json \
-l python \
-o /local/out/


where config looks like

{"packageName": "overt",

I'm using the curl wrapper from the python sdk4, but it misses a lot of high 
level wrappers and helpers. That's what I'm doing, writting code like:

@wrapper(writer_class=StorageDomainWriter, type_class=StorageDomain, 
service_class=StorageDomainService)
class StorageDomainWrapper(ObjectWrapper):
pass


@wrapper(service_class=StorageDomainsService, service_root="storagedomains")
class StoragesDomainWrapper(ListObjectWrapper):
pass


That allows to pack some functions that the sdk splitted or made difficult to 
find. It should allows to write simpler code for end user :

lister = StoragesDomainWrapper(api=...)
sd = lister.get(name="sd1")
print sd.status
sd.export()

Re: [ovirt-users] Ovirt 4, the missing python sdk

[Ben De Luca]

I just generated the python API with the cmdline tools.

I tend to use docker with random things like this from the internet, but
with docker installed this will generate a python version of the api.

docker run --rm -v ${PWD}:/local swaggerapi/swagger-codegen-cli generate \
-c /local/swagger.json \
-l python \
-o /local/out/

to a folder called local/out

The oVirt API has a formal specification, defined in this project:

  https://github.com/oVirt/ovirt-engine-api-model

The skeleton of the server, the documentation, and the SDKs are
automatically generated from that specification.

There is also an experimental Swagger/OpenAPI specification, available here:

  https://jhernand.fedorapeople.org/ovirt-engine-api-model/swagger.json

However this seems to be too big for Swagger tools (1 MiB, 17000 lines).
Every time I tried to load it into Swagger editor or Swagger UI it just
burns the CPU of the browser and never finishes loading. If you have
some Swagger expertise would be nice if you can take a look and pinpoint
what is the problem.

Re: [ovirt-users] change Memory Ballooning setting

Hello oVirt gurus,

When activating/deactivating memory balloning on VM, this will
change /usr/libexec/qemu-kvm command line on host on vm startup (you can
see it using "ps aux").
So I understand a vm reboot is needed to take this change into account.


Right. That option controls the presence of the virtio-balloon device which
is not hotpluggable


But when activating/deactivating memory balloning on Cluster (plus MoM Sync
on host) I do not really understand what happens "under the hood"


This controls the actual behavior, inflating and deflating of those
balloons. That can be done in runtime as it is external to the VM, managed
by MOM demon.


- Is there a mechanism on host which controls "memory balloning" globally?
- Is it able to change it's behaviour "on the fly" with "MoM Sync" ?


Yes. You can change the policy/behavior.

HTH,

Yes,

In fact the python/java/ruby sdk are just wrappers to calling this api.

[ovirt-users] Ovirt 4, the missing python sdk

[Fabrice Bacchella]

I have started to write a custom sdk/cli in python for Ovirt 4. It provides 
helpers and wrapper for the rather raw level sdk4 provided.

It's still a work in progress, but a big improvement from my previous version, 
made for ovirt 3.

It allows to write simple commands on shell :

$ ./ovcmd host -n hostname maintenance
$ ./ovcmd host -n hostname activate

It also allows to do fine exports:

$ ./ovcmd vm -n vmname export os type
rhel_6x64

$ ./ovcmd capabilities -n 4.1 export cpu_types name
Intel Conroe Family
Intel Penryn Family
Intel Nehalem Family
Intel Westmere Family
Intel SandyBridge Family
Intel Haswell-noTSX Family
Intel Haswell Family
Intel Broadwell-noTSX Family
Intel Broadwell Family
Intel Skylake Family
AMD Opteron G1
AMD Opteron G2
AMD Opteron G3
AMD Opteron G4
AMD Opteron G5
IBM POWER8

Or to get a display console on a mac os:

$open $(./ovcmd vm -n vmname console )


It can be found at https://github.com/fbacchella/ovirtcmd/tree/sdk4
It's still works in progress, I need to finish to remove sdk3 code.

Some example of object written to sdk4 can be found at:

In the mean time I have opened this:

Feel free to add any comment.

I would test your suggestions. It seems I already tried them with a
"fenceuser" user, but they didn't work, but it was late in the night and
possibly I missed something... ;-)

It has been very nice in less than a day to make a "poor man" P2V of a
physical 2-nodes RHCS running cluster into oVirt and be able to reproduce
and solve a problem we had during maintenance windows with clvmd not
starting due to timeout issues.
And also with both production and intracluster networks of the virtual
cluster based on OVN, without having to spend time waiting for network
support, due to time constraints we had, as the next maintenance window
will be today...

thanks to all

It should work adding 'UserRole' to 'admin@internal'. The issue is that
the fence agent uses the 'Filter: true' header, thus it drops its
super-user privileges to do the query, and won't get the VM unless it
has explicitly granted permissions. To check it you can do the
following, for example:

---8<---
#!/bin/sh -ex

url="https://yourengine/ovirt-engine/api;
user="admin@internal"
password="..."

curl \
--verbose \
--cacert "/etc/pki/ovirt-engine/ca.pem" \
--user "${user}:${password}" \
--request GET \
--header "Version: 3" \
--header "Filter: true" \
"${url}/vms?search=name%3Dmyvm"
--->8---

That should return the details of the VM, or nothing if the user doesn't
have permission to see that VM.

No, it shouldn't be necessary. Actually, as you are using the 'internal'
domain, it is easy to add a new dummy user without SuperUser privileges.
You can give that user permissions (with 'UserRole') only for the VMs
that are nodes of the cluster. That should be enough.
