Hi,

since file system are usually sparse by default, we use RAW which 
provides better performance than COW.




How i can change the default vm disk from RAW to QCOW2 ??


i thought I saw samples on how to do this via the API/CLI earlier in the 
thread:

http://lists.ovirt.org/pipermail/users/2014-September/027147.html



I am using the below :-
Ovirt :- 3.4.3
Glusterfs :- 3.5

Thanks,

Well yeah, that works somehow, but why can't I open
a bug on these docs? they are available to the public
anyway.

Everybody can investigate them for errors, but I need
a red hat guy to make a report if I find an error? really?

I think I just won't report any doc bugs anymore, because
red hat doesn't seem to want that.


for now, for lack of a better option, I suggest opening them on
ovirt docs.

Hi All,

The disks IDs provided by following two APIs will be same or different?

* SERVER:PORT/api/vms/VM_ID/snapshots/ID**/disks**

[ovirt-users] Ovirt / RHEV interoperability

[John Gardeniers]

Just curious and I'm not currently in a position to try it myself. Is 
there any interoperability between Ovirt and RHEV? In other words, can 
an Ovirt hypervisor work with a REV engine or can a RHEV hypervisor work 
with a RHEV engine?

[ovirt-users] OVirt Guest Agent Service service could not be started

[Richard Long]

I am trying to install ovirt-guest-agent in a windows 7 sp1 vm with all current 
updates applied. This is a new install for  of oVirt Engine Version: 
3.4.3-1.fc19. Both host are running FC20.
 Besides searching the list and google I have followed the instructions here: 
http://www.ovirt.org/OVirt_Guest_Agent_For_Windows.  
I tried many different things to no avail and this install is on a clean win 7 
vm.
During the creation of the service I am getting this warning:  

The following modules appear to be missing
['Carbon', 'Carbon.Files', '_scproxy', 'dummy.Process', 'simplejson', 
'test_port ', 'win32com.gen_py']. 
I do not know if these are needed are  not and have not been able to locate 
them.

After copying the files created in the python build ,per the instructions I ran 
the following :

C:\Program Files (x86)\Guest Agents\oVirt Guest Agent> OVirtGuestService.exe 
-instal
C:\Program Files (x86)\Guest Agents\oVirt Guest Agent> net start 
OVirtGuestService

and get

The OVirt Guest Agent Service service is starting.
The OVirt Guest Agent Service service could not be started.

 A service specific error occurred: 1.

More help is available by typing NET HELPMSG 3547.

Which gives: A service specific error occurred: ***.


Looking at the windows system event log gives:

The description for Event ID 10 from source OVirtGuestService cannot be found. 
Either the component that raises this event is not installed on your local 
computer or
 the installation is corrupted. You can install or repair the component on the 
local computer.

If the event originated on another computer, the display information had to be 
saved with the event.

The following information was included with the event: 

Traceback (most recent call last):
  File "OVirtGuestService.pyc", line 63, in __init__
  File "logging\config.pyc", line 70, in fileConfig
  File "logging\config.pyc", line 106, in _create_formatters
  File "ConfigParser.pyc", line 607, in get
NoSectionError: No section: 'formatters'


And 

The OVirt Guest Agent Service service terminated with service-specific error 
Incorrect function..

As I said I have scoured the internet for a resolution for 2 days, one hinted 
at the serial driver:

I device manager the VirtIO-Serial Driver is listed and "This device is working 
properly."

I'm not sure what to try now.

Richard

Re: [ovirt-users] VM File System expansion

[Punit Dambiwal]

Hi Rich,

I read this article :-

and used below set of commands :-

Virtual Machine File System expansion


oVirt 3.4 disks can be online expansion, but for the disk within a file
system requires a separate support for Linux and Windows lists commonly
used method in this expansion.

*Linux file system expansion (libguestfs)*

For details, please refer to libguestfs site

 .

   1. View disk

  # Virt-filesystem --all --long -h -a hda.img


   1. Expansion disk copy to be created, while the expansion of 10G
   (Assuming the original disk size is 10G)

For RAW format:

  # Truncate -r hda.img hda-new.img
 # Truncate -s + 10G hda-new.img

For QCOW2 and other compressed formats:

  # Qemu-img create -f qcow2 -o preallocation = metadata hda-new.img 20G


   1. Extended partition size

Ordinary extended partition, / boot partition expansion 200M, all the rest
to the / partition:

  # Virt-resize --resize / dev / sda1 = + 200M --expand / dev / sda2

LVM partition expansion, expansion lv_root logical volume:

  # Virt-resize --expand / dev / sda2 --LV-expand / dev / vg_livecd /
lv_root hda.qcow2 hda-new.qcow2

Re: [ovirt-users] How to backup/restore the rhevm-VM in hosted-engine ?

[Groten, Ryan]

In 3.4 there is a backup/restore utility called engine-backup.  You can use 
this to backup the RHEV-M database(s) as well as restore.  Of course this won't 
backup the Guest OS itself.
My DR strategy is to simply copy off these engine-backup files to another 
location.  If the hosted-engine needs to be restored for some reason I will 
just recreate the OS and restore the engine database.

Check this link for documentation:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.4/html/Administration_Guide/chap-Backups.html

Hi,All
 As the mauual, I can't find anyway to backup/restore the rhevm-VM in 
the hosted-engine. The I just try to backup the storage of rhevm-VM (using cp 
-prf  to make a copy of folder). Then I make some change and replace the origin 
RHEVM-VM content with my backup folder (of course I shutdown the rhevm-vm 
first).  At last the vm can be up,but the status is NOT health but as below:


Status up-to-date  : False
Hostname   : 193.168.195.248
Host ID: 1
Engine status  : unknown stale-data
Score  : 2400
Local maintenance  : False
Host timestamp : 1409743461
Extra metadata (valid at timestamp):

 host-id=1
 score=2400
 maintenance=False
 state=EngineUp

=

So are there some proper way to backup the rhevm-vm?

it sounds like the host network is not configured correctly,
when you go to the host in the webadmin, select the network subtab
you should see there the host nic and the network it is attached to, i assume 
it will be blank,
where the vm nic is assigned to the cluster network, ovirtmgmt (as it should..)

try to use setup networks (in that host' network subtab) to fix that (i think 
its just drag and drop the network on the nic)

As far as I can see, only the management network is listed and looks like it's 
working.
ovirtmgmt has 10.0.0.1 as ip address so it has one.

I can't see it in the output, but maybe it's the display network?
if you got one, it _must_ have an ip assigned, I opened a bug about
this not very informative error message and I guess it's already fixed
in master.

Make sure all cluster wide defined networks are available on your host.

Can you run it again with the -v flag and paste the output?
Also, why are you using iso uploader for an ova instead of image uploader?

As I said I am not a cloud-init expert, so I don't really know what is
the meaning or effect of this script. But I think that you need to use
the "runcmd" option. For example:


  ...
  
...

  


If you use this it should run the "touch /iwashere" command, and you can
check that it did verifying that the "/iwashere" file exists.

As I said I didn't test this, so I may not work. I'd appreciate if you
can test it, and once it works update the wiki with the correct
instructions:

Re: [ovirt-users] Passing custom script to cloud init using api

[Shanil S]

Hi Juan,

Okay.. Thanks for your update. Also i found some sample cloud init scripts
from here https://github.com/number5/cloud-init/tree/master/doc/examples
and i tried the following scripts

- type: foo/wark
filename: bar
content: |
This is my payload
hello
- this is also payload
- |
multi line payload
here
-
type: text/upstart-job
filename: my-upstart.conf
content: |
Test file contents

And run the start vm using the above script using cloud init and api, Could
you please tell me where i can find the result of the above script ?
I think the above script will create a file like my-upstart.conf

You can deploy files using cloud-init, and the run them using the custom
script. Something like this:

  
...

  

  

  

  
  

  

But I'm not a cloud-init expert, and I didn't test this, so I don't
really know if the custom_script will run before or after the files are
deployed. It makes more sense to run the scripts after deploying the
files, but you will have to test it yourself.

The content of the files and the scripts has to be embedded in the XML
document that you send to the RESTAPI server, there is no way to send an
XML document and a separate file. Building this kind of XML document
shouldn't be complicated if you use the CDATA syntax like in the example
above.

Another thing that you may consider, if you have to run a complicated
script or set of scripts, is to have them pre-installed in the template
that you use to create the VM, then you just need to run them.

Which article?

virt-resize can only be used for offline expansion of disks.

If you used virt-resize, what precise commands did you type and
what exact errors did you see?
