Re: [Users] Ovirt Node install to USB stick - required 70GB disk space?

2013-01-08 Thread Alexandru Vladulescu

Hi,

I have 2 hypervisors running on 2 usb 3.0 sticks and the a swap daemon running 
on a NFS share export.

The daemon only creates swap space when needed, so I have not used the swap 
partition during the os install on the usbs.

Each physical server has 32gb of ram.

So far i did not experienced any performance degradation.

Regards,
Alex

 Hi,
 
 has anybody installed ovirt-node on a bootable usb stick? If the

 is less than 1GB in size, why does installation require 70GB of disk

 It would be perfect to run nodes from usb without any disks.

 Sorry for not asnwering to the list, here are my previous post:
 
 How much memory do you have? It seems that it's calculating how much
 swap it will need and turns that needs at least 70 GB disk space.
 
 There is a thread in this forum that has the calculations that ovirt
 does for it. You can change this values on the boot options.
 
 Alex
 Those values are also shown on the installer screen right before entering 
 the password and can be changed
 
 As sometimes searching the list can be a pain, I'll just repost it:
 
 You can do this with 2 different methods, both of which are on the kernel 
 command line during boot. Simply hit TAB when you're selecting the install 
 option and add one of the options below to the command line.
 
 1.  You can set  storage_vol=:XXX   where XXX is the desired size of 
 the SWAP partition in MB.  It has a minimum size of 5MB.
   This lets you set a static size for swap.
 
 2.  You can set mem_overcommit=0.  This will change our calculation to not 
 add any swap for overcommit.  It will still calculate a value based on the 
 amount of RAM, but not as large as with the overcommit.
 
 The swap size is calculated at mem_overcommit*RAM + BASE_SWAP
 
 BASE_SWAP is calculated using this formula:
 
 if MEM_SIZE  4GB:
 BASE_SWAP = 2GB
 elif MEM_SIZE  16GB:
 BASE_SWAP = 4GB
 elif MEM_SIZE  64GB:
 BASE_SWAP = 8GB
 else:
 BASE_SWAP = 16GB
 
 
 We are planning to expose these option in the TUI installer, just not there 
 yet.

[Users] Best practice to resize a WM disk image

2013-01-08 Thread Ricky
Hi,

If I have a VM that has run out of disk space, how can I increase the
space in best way? One way is to add a second bigger disk to the WM
and then use dd or similar to copy. But is it possible to stretch the
original disk inside or outside oVirt and get oVirt to know the bigger
size?

 have a MacPoolManager infrastructure which holds a pool of Mac

 one for production and one for testing, you will get collisions?

[Users] OS-independent ovirt-engine distribution archive

2013-01-08 Thread Jiri Belka
Hello,

I'm very slowly working to make ovirt-engine running on a BSD system.
My problem is that I do it for fun and as my time resources are not big
I could not choose building ovirt-engine from sources as it would push
me to port (make packages) for all java dependencies. Yes, during
build maven cannot download Internet and build dependencies (for
security reasons).

Would be possible to have (another) distribution archive of
ovirt-engine which would be OS/distro-independent, so I could just
extract and copy it to filesystem for local jboss? (RPM packages can be
extracted with 'rpm2cpio' but their owners decided to make life very
complicated [many symlinks etc.]).

OS/distro-independent distribution archive (.zip, .tgz) would make life
much easiers for people wanting to have ovirt-engine running on a
non-RPM based Linux distro or on a BSD/Solaris system.

  the

 This is what I would like but it should be done by ovirt team itself.
 BSD port systems (are generally just Makefiles) can _only_ download
 official archives and build them locally.

When using maven the whole concept of official archive is different.
BSD ports build from source, so it should download sources, and sources do not 
include any of the external dependency nor binaries.
Am I right so far?

The problem with maven is that it downloads dependencies during source build, 
which is invalid approach as far as build methodology is concerned... but it is 
what it is.

The Fedora project added wrapper to force maven to use local repository and for 
maven artifacts to be installed at this local repository. This is healthy 
solution as you build dependencies as standard packages, then maven will fetch 
and use these local packages. 

What you seek is binary distribution so ports will use binaries, is that 
matches *BSD policy?

 
  Of course help will be appreciate, we are planning to solve the

  issue by rewriting it to match otopi infrastructure it will be one
  step closer to be able to customize it to different distributions.

Re: [Users] Best practice to resize a WM disk image

2013-01-08 Thread Rocky
Its just a theoretical question as I think the issue will come for us
and other users.

I think there can be one or more snapshots in the WM over the time. But
if that is an issue we can always collapse them I think.
If its a base image it should be RAW, right?
In this case its on file storage (NFS).

[Users] libvirt dependency vs. a way to have Solaris hosts in ovirt-engine

2013-01-08 Thread Jiri Belka
Hi,

as you know Solaris (Open Indiana) has qemu-kvm although they don't use
libvirt (in fact libvirt tighted to much to Linux specifics).

If vdsm whould interact with qemu-kvm without libvirt it would open a
way to have Solaris hosts in ovirt-engine.

libvirt is another abstraction after vdsm layer, or if vdsm could use
plugins to interact with qemu-kvm (libvirt, native, solaris-style),
it could use current mode, bypass libvirt and use solaris tools to talk
to their qemu-kvm.

you can't move a cluster while it associated to a DC, you need to delete

Hi Gianluca,

You could try the following:

- Create new datacenter and cluster
- Set VLAN for ovirtmgmt network in new DC
- Delete localhost from Default cluster
- Configure VLAN tagging on host manually
- Join localhost to new cluster using oVirt Admin Portal

Before joining localhost to the new cluster, comment out rebooting in
vds_bootstrap_complete.py:

$ vi /usr/share/vdsm-bootstrap/vds_bootstrap_complete.py
#deployUtil.reboot()

René

 2) put CL1 in DC2
 3) edit ovirtmgmt in DC1

The Server is a single machine and i want to use them with the all-in-one 
plugin from ovirt. 

I do some tests with: 
Fedora 17, CentOS6.3, Oracle Linux 6.3 
latest kernel, qemu-kvm and libvirt from repos. No extras or advanced 
configurations. Only a simple standard Server. 

I install yum groupinstall virtualization + virt-manager and some other. 
I configure iommu, modul blacklist and some other. 

Then i starting a Windows Server 2003 and assign the parallel adapter to the 
running server. I look in the device manager and found the adapter card. 
The dongle work finde and the Datev Lizenz Service are online. 

.. so far so good 

but when i install on the same Server ovirt. With same kernel qemu-kvm and 
libvirt! 
And i attach the adapter card to the windows server 2003 look in the device 
manager and found the card with a error device cannot be start (code 10) 

I am now looking for several days after the error and have diverse tried but I 
can not keep going. 

can someone help me?

 The memAvailable field can be negative and considers a set of values from 
 different sources to compose its result (free memory, cached memory, resident 
 set size from qemu processes, committed memory from running vms and host 
 reserved memory

 Hi Alex,

 You can already group VMs using tags or search filters...

Re: [Users] Best practice to resize a WM disk image

2013-01-08 Thread Yeela Kaplan
So, first of all, you should know that resizing a disk is not yet supported in 
oVirt.
If you decide that you must use it anyway, you should know in advance that it's 
not recommended,
and that your data is at risk when you perform these kind of actions.

There are several ways to perform this.
One of them is to create a second (larger) disk for the vm, 
run the vm from live cd and use dd to copy the first disk contents into the 
second one,
and finally remove the first disk and make sure that the new disk is configured 
as your system disk.
The second, riskier, option is to export the vm to an export domain,
resize the image volume size to the new larger size using qemu-img and also 
modify the vm's metadata in its ovf,
as you can see this option is more complicated and requires deeper 
understanding and altering of the metadata...
finally you'll need to import the vm back.

 Its just a theoretical question as I think the issue will come for us
 and other users.
 
 I think there can be one or more snapshots in the WM over the time.
 But
 if that is an issue we can always collapse them I think.
 If its a base image it should be RAW, right?
 In this case its on file storage (NFS).

  Hi Ricky,
  In order to give you a detailed answer I need additional details
  regarding the disk:
  - Is the disk image composed as a chain of volumes or just a base
  volume?
  (if it's a chain it will be more complicated, you might want to
  collapse the chain first to make it easier).
  - Is the disk image raw? (you can use qemu-img info to check)
  - Is the disk image on block or file storage?

[Users] local variable 'volPath' referenced before assignment

2013-01-08 Thread Frank Wall
Hi,

I've updated my oVirt engine and node from version 3.1.0-2 to the
more recent 3.1.0-4. As far as I can tell from the update log, the
engine update went fine by following these instructions:
https://www.rvanderlinden.net/wordpress/ovirt/engine-installation/engine-upgrade/

Now I'm unable to start a VM through the Admin Portal. It fails with
the following error message:

VM test_srv is down. Exit message: local variable 'volPath' referenced before 
assignment.

What's wrong? It seems this message is related to this bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=843387
But apparently there is no solution.

What is the fix or workaround to get VMs working again?


Thanks

2013-01-08 Thread Yeela Kaplan
Hi Frank,
It looks like the same issue as in the bug,
the bug also references a Change-Id for a fix: 
I8ad50c3a3485812f57800bbe6b7318a90fe5b962
and you can also access this patch in the following link: 
http://gerrit.ovirt.org/#/c/6794/2

Can you tell if the vdsm version installed on your host includes this patch?
(you can check under /usr/share/vdsm/clientIF.py).
If it's in there please send the full logs (engine+vdsm) and the bug might need 
to be reopened,
otherwise you can just upgrade vdsm and hopefully it would solve the problem.

Regards,
Yeela

 Alexandru Vladulescu :
 
  Dear Shu,
 
 
  Exactly what I was saying, in that section we can only change in
  the
  Advanced Parameters the NFS version, the Retransmissions and the
  Timeout.
 Sorry, was not seeing these. I am afraid you can not append other
 options, for neither ovirt engine nor VDSM accepts other options than
 Retransmissions and the Timeout.

Hi, 

first, please open an RFE for it: 
https://bugzilla.redhat.com/enter_bug.cgi?product=oVirt
second, you can set it in vdsm.conf configuration file (/etc/vdsm/vdsm.conf).

as for how to do it, check out sample config file distributed with the rpm:

/usr/share/doc/vdsm-4.9.6/vdsm.conf.sample

make sure to restart vdsmd service on each hypervisor afterwards.

Haim

 
 
  Therefore I see exactly no field for additional mount options.
 
  As I know there is a thread on the mailing list about the new
  features
  that should be included in the 3.2 version release. I think would
  be
  useful to include this one too to the GUI, but again my question,
  how
  could this be modified in the stable 3.1 release ?
