[one-users] blktap xen 4.2 and opennebula 4.2

[kenny . kenny]

Hello, i need to use blktap instead of default disk drive.
 
i changed /var/lib/one/remotes/vmm/xen4/attach_disk and /etc/one/vmm_exec/vmm_exec_xen4.conf , but when take a look at deployment.0 , it always with "file:".
What i need to do to change that ?
 
I will change it beacuase with file i can run just 8 vm per node.
 
 
thank

I could be wrong, I'm new to OpenNebula myself, but from what I've seen,
the management node isn't a particularly heavyweight process.

I had it running semi-successfully on an old server here (pre
virtualisation-technology).  I say semi-successfully; the machine had a
SCSI RAID card that took a dislike to Ubuntu 12.04, so the machine I had
as the master would die after 8 hours.

I was using SSH based transfers (so no shared storage) at the time.

Despite this, the VMs held up, they just couldn't be managed.  This
won't be the case if your VM hosts mount any space off the frontend
node: in which case a true HA set-up is needed.  (And lets face it, I
wouldn't recommend running the master node as a VM if you're going to be
mounting storage directly off it for the hosts.)

Based on this it would seem you could do a HA setup with some shared
storage between the nodes, either a common SAN or DR:BD to handle the
OpenNebula frontend.

Seeing as OpenNebula will want to control libvirt on the hosts (being
that you're also suggesting making these run the OpenNebula-managed VMs
too, this might have to be a KVM process managed outside of libvirt.
Not overly difficult, just fiddly.

But, as I say, I could be wrong, so take the above advice with a grain
of salt.

Re: [one-users] More ipv6 network questions

[Steven Timm]

A followup--I did find an example in the documentation but it is only for 
"RANGED" IPv6 network.  I need a FIXED IPv6 network.


I saw that when I set an IP6_GLOBAL PREFIX in the network
file it would then append the ipv6-ified mac address of the
machine and construct an IP6_GLOBAL for me.  But that's not what I want.

Would like to do something like this:
LEASES = [ IP="131.225.41.182", MAC="54:52:00:02:0B:01", 
IP6_GLOBAL="2001:400:2410:29::182" ]
LEASES = [ IP="131.225.41.183", MAC="54:52:00:02:0B:02", 
IP6_GLOBAL="2001:400:2410:29::183"]
LEASES = [ IP="131.225.41.184", MAC="54:52:00:02:0B:03", 
IP6_GLOBAL="2001:400:2410:29::184" ]
LEASES = [ IP="131.225.41.185", MAC="54:52:00:02:0B:04", 
IP6_GLOBAL="2001:400:2410:29::185" ]
LEASES = [ IP="131.225.41.186", MAC="54:52:00:02:0B:05", 
IP6_GLOBAL="2001:400:2410:29::186" ]


But this doesn't work.  the IP6_GLOBAL in the LEASES field is ignored.

Is there any IPV6-related field that is accepted in the LEASES
field of a fixed-network network template?  This is of some urgency.
(I promised my users who depend on ipv6 cloud vm's I would have them
up this morning local time and it is now quitting time today).

It's puzzling because in the "leases" database table there

3) Do the contextualization rpms as distributed with ONE4.0 and greater

If so, what fields should we put in the CONTEXT section
to set these values?

Any help is appreciated as getting the ipv6 VM's up and running

the ipv6 addresses by hand once the VM is up.

Re: [one-users] Fault Tolerance and shared storage

[Tino Vazquez]

Hi,

Thanks for the info.

The hook for host error in OpenNebula 4.4 allows to define one, and only
one, of the "-r" and "-d" flags:

   * -r will "delete --recreate" the VM in the failed host, this will go
through the epilog_delete phase, and it should erase the sym links and
launch the VM again. This is probably what you want, please come back if
the problem does not go away

  * -d will "delete" the VM in the failed host, but won't launch the VM
again.

These two are mutually exclusive.

Regards,

-Tino

[one-users] Fault Tolerance and shared storage

[Nuno Serro]

  
  
Hello,

We've started using a system datastore whith a shared
  storage in a clustered fs, so we could start testing the live
  migrate functionality. The live migrate is working as expected,
  but when testing the fault tolerance using the host_hook, we
  noticed the following error:

[TM][I]:  ln -s "/dev/vg-nebula/lv-one-144"
  "/var/lib/one/datastores/109/393/disk.0"" failed: ln: failed to
  create symbolic link `/var/lib/one/datastores/109/393/disk.0':
  File exists
[TM][E]: Error linking /dev/vg-nebula/lv-one-144

I understand the error. When I kill one node and host_hook
  kicks in, being the storage shared between nodes, the symlinks to
  the images are already there.

My question is regarding the hook definition:

HOST_HOOK = [
    name  = "error",
    on    = "ERROR",
    command   = "ft/host_error.rb",
    arguments = "$ID -r",
    remote    = "no" ]

  Is it possible to configure the hook to delete the VM, and
  afterwards creating it? We tried combining "-d" and "-r" flags but
  only one flag seems to be used.
  
  Thanks in advance.

Re: [one-users] Problem boot VM template with opennebula

[Javier Fontan]

Let's try taking out a couple of parameters. KERNEL_CMD, swap disk,
device_model and VNC. I'm using the template you provided in a
previous email:

NAME   = Encourage7
MEMORY = 4096
CPU= 1
OS=[ KERNEL = "/boot/vmlinuz-2.6.32-279.el6.x86_64", INITRD =
"/boot/initramfs-2.6.32-279.el6.x86_64.img", root = "xvda1" ]
DISK =[ DRIVER="file:", IMAGE_ID="27", TARGET="xvda1" ]
NIC = [ NETWORK_ID = 3 ]

In case this works you can start adding some other parameters. I'll
start with the swap disk.

Can you send us the deployment file generated by OpenNebula? Just to check if 
there is something too different to your deployment file. It should be located 
in you frontend at
/var/lib/one/vms//deployment.0

Doesn't `apt-get purge ` remove the package *and* its config files?

That followed by an `apt-get autoremove` since the deps will have
nothing requiring them to stick around.

Re: [one-users] ceph+flashcache datastore driver

Hi Shankhadeep,

Cheers for the heads up, I will have a look.  What are you using to
implement the SAN and what sort of VMs are you using with it?

One thing I'm finding: when I tried using this, I had a stack of RBD
images created by OpenNebula that were in RBD v1 format.  I converted
them to v2 format by means of a simple script: basically renaming the
old images then doing a pipe from 'rbd export' to 'rbd import'.

I had a few images in there, most originally for other hypervisors:
- Windows 2000 Pro image
- Windows XP Pro image (VMWare ESXi image)
- Windows 2012 Standard Evaluation image (CloudBase OpenStack image)
- Windows 2008 R2 Enterprise Evaluation (HyperV image)
- Windows 2012 R2 Data Centre Evaluation (HyperV image)

The latter two were downloaded from Microsoft's site and are actually
supposed to run on HyperV, however they ran fine with IDE storage under
KVM under the out-of-the-box Ceph support in OpenNebula 4.4.

I'm finding that after conversion of the RBDs to RBDv2 format, and
re-creating the image in OpenNebula to clear out the DISK_TYPE attribute
(DISK_TYPE=RBD kept creeping in), the image would deploy but then the OS
would crash.

Win2008r2 would crash after changing the Administrator password (hang
with black screen), Win2012r2 would crash with a CRITICAL_PROCESS_DIED
blue-screen-of-death when attempting to set the Administrator password.

The other images run fine.  The only two that were actually intended for
KVM are the Windows 2012 evaluation image produced by CloudBase (for
OpenStack), and the Windows 2000 image that I personally created.  The
others were all built on other hypervisors, then converted.

I'm not sure if it's something funny with the conversion of the RBDs or
whether it's an oddity with FlashCache+RBD that's causing this.  These
images were fine before I got FlashCache involved (if a little slow).
Either there's a bug in my script, in FlashCache, or I buggered up the
RBD conversion.

But I will have a look at bcache and see how it performs in comparison.
 One thing we are looking for is the ability to throttle or control
cache write-backs for non-production work-loads ... that is, we wish to
prioritise Ceph traffic for production VMs during work hours.
FlashCache doesn't offer this feature at this time.

Do you know if bcache offers any such controls?

Re: [one-users] use of image CACHE attribute in images

Hi Olivier,

You need to update the VM Template, not the IMAGE. You can find the CACHE
attribute in the Storage (DISK) section under advance.

Cheers

[one-users] use of image CACHE attribute in images

[Olivier Sallou]

Hi,
I have opennebula 4.2 over KVM and was trying to use the CACHE attribute
to set it to  'writeback' (according to
http://archives.opennebula.org/documentation:archives:rel4.2:template#i_o_devices_section).
I indeed face very slow disk I/O though using ext3 filesystem and virtio.

I have tagged my image with a tag CACHE, but I do not see it in
generated template. I have the DEV_PREFIX (used for virtio), but no CACHE.

Any idea of what is going wrong ? There is no eror in the logs

Thanks

Olivier

Re: [one-users] Request for comments: Sunstone dashboard

[ML mail]

Hi Carlos,

I think it would be nice to to see some more "white labeling" features/options 
where one does not need to directly modify the code of sunstone. For example 
the "OpenNebula App Market" title on the app market page does not make sense 
when someone uses its own appmarket server. Just some small details... 
functionality, easy-of-use, and speed are of course more important.

Regards
M.L.

Dear community,


As you may know if you tried the beta release, we are doing a facelift to 
Sunstone. We are now improving the refresh mechanism to improve the performance 
and alleviate the load Sunstone puts on OpenNebula.

To remove as many refresh calls, we are going to simplify the dashboard. Right 
now it shows aggregated historic graphs for the VM network speed, and the Host 
CPU and Memory.

We will change it to show only the instantaneous number of VMs in each state, 
and the instantaneous cpu and memory usage. Plus the existing storage, users, 
and network stats. Possibly, we will also add the current quota usage.

The information shown by the graphs we are going to remove will be still 
accessible for each VM/Host in the individual info view.


We'd appreciate your comments on what information you would like to see in the 
dashboard, for both admins and regular users.

Best regards,
Carlos
