Info on python SDK variable definition
by Gianluca Cecchi
Hello,
suppose in a .py using sdk I have
my_var1 = 'prefix'
then in the workflow I get at runtime another my_var2 that for example has
the attribute
my_var2.name that equals "suffix"
Then I want to define a new variable my_var3 with value "prefix_suffix",
where the string "suffix" is known only at runtime, how can I get it?
my_var3 = ???
Can I use something similar to what I do when using the print function?
print ("My storage domain is %s..." % sd.name)
?
Thanks,

oVirt Python SDK and monitor export as OVA task
by Gianluca Cecchi
Hello,
sometimes I have environments (typically with Oracle RDBMS on virtual
machines) where there is one boot disk and one (often big, such as 500Gb or
more) data disk.
The data disk has already its application backup (typically RMAN) and I
want to complement it with a backup of only the boot disk of the operating
system and VM configuration.
I'm almost done completing a script using oVirt Python SDK and sharing for
comments.
I could be wrong, but I didn't find any ansible module to do this with
Ansible playbooks: I can only save all the VM, that in my case wouldn't be
necessary and instead time and storage wasting.
The basic steps are:
- make a snapshot of the target vm, composed only by the boot disk
- clone the snapshot
- export the clone as OVA
- delete clone
- delete snapshot
There are some things to discuss about, probably when I will share the
overall job (such as the name to give to the boot disk, if not using the
bootable flag, the way to import the OVA in case of actual need, where you
will have to comment out some fs entries related to missing disks, ecc.).
The only thing missing is how to monitor the export to ova task that, as
with Ansible, it completes almost immediately, while the export is actually
altready running.
I need to monitor it, so only at its real end I can run the last 2 steps of
the above list of tasks.
Can you give me any hint? Not found very much in guide or docs on the web.
I'm currently using a sleep because my boot disk is about 20Gb in size and
I know that in less than 2 minutes it normally completes.
The export as ova is very similar to what found in the examples and they
don't contain a monitor for it but only the connection.close() call:
cloned_vm_service.export_to_path_on_host(
host=types.Host(id=host.id),
directory = export_as_ova_dir,
filename = cloned_vm.name + '.ova'
)
Thanks in advance,
Gianluca

EqualLogic SAN controller switchover
by Chris Adams
How well does oVirt handle an EqualLogic SAN controller switchover
event? IIRC that can result in a short iSCSI "pause" (can't remember
how long it takes) - I'm not sure what oVirt's threshold before VMs
(including the hosted engine) get paused for storage timeouts.
I've got a small setup where the active SAN controller's battery has
gone bad, so I need to switch to the other controller, and I'm trying to
figure out the impact - do I need to shut all VMs (including the engine)
down first, will they just briefly pause and then continue, etc.

oVirt 4.3.8 ovn vms doesn't ping
by Gianluca Cecchi
Hello,
I have an environment with oVirt 4.3.8.
All seems ok from a configuration point of view, but if I use OVN based
interfaces on two VMs, they are not able to ping, both if I put them on the
same host and if I put on different hosts.
At this point they are both running on the same host and their only vnic is
on ovn172 network (defined as 192.168.172.0/24).
I have this
manager
# ovn-nbctl show
switch fc2fc4e8-ff71-4ec3-ba03-536a870cd483
(ovirt-ovn192-1e252228-ade7-47c8-acda-5209be358fcf)
switch 87012fa6-ffaa-4fb0-bd91-b3eb7c0a2fc1

port aaddc425-3a38-49bf-bfc7-9eaeab82906e
addresses: ["00:1a:4a:19:01:58 dynamic"]
The two macs correspond to what I see for VMs in web admin gui and at os
level of the two VMs.
On the host where VMs are running I have:
# ovs-vsctl show
f1a41e9c-16fb-4aa2-a386-2f366ade4d3c
Bridge br-int
fail_mode: secure
Port "ovn-b8872a-0"
Interface "ovn-b8872a-0"
type: geneve
options: {csum="true", key=flow, remote_ip="10.4.192.34"}
Port br-int
Interface br-int
type: internal
Port "vnet0"
Interface "vnet0"
Port "ovn-1dce5b-0"
Interface "ovn-1dce5b-0"
type: geneve
options: {csum="true", key=flow, remote_ip="10.4.192.32"}
Port "vnet1"
Interface "vnet1"
ovs_version: "2.11.0"
So apparently I see the vnet0 and vnet1 ports associated with the two VMs
How can I check more in depth the reason why they don't ping?
Both VMs are CentOS 8.1 but I don't know if it is relevant.
Thanks,
Gianluca

oVirt 4.3.8 and almost unpredictable export as ova duration
by Gianluca Cecchi
Hello,
on a test oVirt environment I have export as ova task that, based on same
disk size (20Gb) it could last 35 seconds or 11 minutes....
During the long lasting test I see on host that almost all and only I/O (in
the measure of 6-7 MB/s) is done by a [loop0] process that has ppid 2 and
apparently (with "fuser" command on /dev/loop0 file) is uses by noone.
Is it implicitly used by the "qemu-img convert " command of the export as
ova?
Why so great difference in elapsed time? The disk is the same of the same
VM.
The oVirt env has almost nothing running only 2 CentOS 8.1 VMs doing
nothing.
Same host used for export as ova in the two runs in a 20 minutes timeframe.
As the path for OVA I'm temporarily using a connected export domain
subdirectory, using
directory='/rhev/data-center/mnt/10.4.192.69:_export_ovirt/dump'
Donna if it can have a role in the problem...
Thanks,
Gianluca

Re: Huge increase of CPU load on hosted engine VM after upgrade to 4.3.8 and cluster compatibility version
by Florian Schmid
Hi,
no, fortunately, the bug didn't came back.
It looks like, that the engine needs its time to settle after changing the cluster compatibility version. After about 2 hours, the CPU load was as low as before.
The time to load the VM UI takes a little bit more time, but I think this is also normal, because all VMs still have the orange triangle and need a reboot.
Sorry for the false positive, but I was really afraid about the high load.

Caution External Mail: Do not click any links or open any attachments unless you trust the sender and know that the content is safe.
Hi,
I have upgraded yesterday one of our ovirt environments from 4.2.8 to 4.3.8.
We have a hosted engine, 25 hosts and about 150 VMs running there.
After upgrading the cluster compatibility version from 4.2 to 4.3, I have seen a huge increase of CPU load on the engine VM.
The engine had 4 cores (16GB mem) and never had load issues, but after the upgrade, the system has a load of 6 and more. I have increased the CPUs to 8, because working in the UI was impossible.
I have noticed, that the load always increase, when I load the VM UI tab, where now all VMs have the orange triangle with pending changes: Custom compatibility version
The problem I have, is, that I can't reboot now all VMs, maybe in the next 3 or 4 weeks.
Working now with the UI is quite problematic, because of the slowness.
The engine VM was already rebooted, but didn't solve the problem.
What logs do you need and is there a workaround available? I have some more oVirt environments to upgrade, all with even more VMs.
BR Florian

oVirt Storage quota questions
by Vrgotic, Marko
Dear oVirt,
My platform is running SHE oVirt version 4.3.8.
Why is my StorageQuota consumption still showing “ 0 out of 3700” ? Did I forget something?
[A screenshot of a cell phone Description automatically generated]
I have setup storage quota “StorageQuota” for one of domains.
It has 4400GB actual storage.
* Quota is set to 3700GB.
* Treshold for Quota is 85% and Grace is set to 110%.
* Datacenter Quota is set to Enforced
* The template image has been changed from Default to StorageQuota
* I see that Vms created from Template are automatically assigned StorageQuota
To present the following situation in screenshots:
* Actual Quota:
[A screenshot of a social media post Description automatically generated]
* VMs (more than on the screenshot) which have the StorageQuota assigned:
[A screenshot of a social media post Description automatically generated]
* Templates which have the StorageQuota assigned
[cid:image004.png@01D5ED57.6C02ACF0]
Kindly awaiting your reply.
Additionally – is there an easy&safe way to update all running VMs quota?
