Re: [one-users] LVM / shared datastores running OS inside a USB stick

[Jaime Melis]

Hi Pablo,

LVM provides a few advantages in some scenarios, but generally a shared
file system like NFS fits more uses cases.

In a nutshell the difference between these two datastores is:
* lvm: images are registered into LV. When a VM is instantiated, the LV is
cloned to another LV in the same VG. The drawback is that it takes up a lot
of space
* fs_lvm: images are stored as files. When a VM is instantiated, the file
is dumped into an LV in the VG with the name vg-one-

In either case, the system datastore is a file-based datastores:. Take a
look at the table in this section:
http://docs.opennebula.org/4.6/administration/storage/sm.html#planning-your-storage
Only shared and ssh can be system datastores (and vmfs for VMware).

cheers,
Jaime

[one-users] Rentalia - Experiences with OpenNebula and Bacula

[Tino Vazquez]

Dear OpenNebula users,

We thought you might find interesting this post [1] where Rentalia
folks explain how they integrate OpenNebula and Bacula to keep a
backup of all the VM images. We know this integration is widely
demanded, so if you want to try it out and extend the integration,
this is the perfect post to start with!

If you want to report your success story with OpenNebula, please send
us a line to  so we can take it to the
OpenNebula blog.

[one-users] How use $UNAME

[Alexandr Baranov]

Hi,

I'm trying to setup kerberos login to log into VMs with kerberos username
matching ONE username. I'm going to use UNAME variable and ONE
documentation states it as pre-defined. So the question is: do I need to
manually specify UNAME inside the VM template, or is it automatically
defined and passed to contextualization scripts?

Re: [one-users] How use $UNAME

[Valentin Bud]

Hi Alexandr,

It is defined but not automatically included. You have to configure it
in the template.

CONTEXT=[
UNAME="$UNAME"
]

You can, of course name the variable inside the CONTEXT as you wish.

I am using ONE 4.4 and the above applies to this version, I don't know if
4.6 includes the pre-defined variables by default.

Best,
Valentin

Hi Alexandr,

Can you post your template please. Have you somehow defined two CONTEXT
arrays inside the template?

Bad Request : "[VirtualMachineAllocate] Error allocating a new virtual

The above makes me think you did.

[one-users] onevm migrate/suspend and checkpoint files

[Steven Timm]

When OpenNebula creates a checkpoint file either as part
of a onevm migrate or onevm suspend, what libvirt function
is it calling to do the checkpoint?

We are seeing some issues on our new Ivy Bridge hardware
that sometimes in the process of a (non-live) migration,
the clock can get confused in such a way that when the
virtual machine starts from the checkpoint file
it will be hung and the kvm process uses 100% of cpu for
a day or more, and then usually resolves itself.  In some
cases we see the clock jump very far into the future (2598),
which in itself can confuse a linux vm enough to hang it.

Any clues on what OpenNebula /libvirt are doing under the covers?
Is there any reason to suspect that on Ivy Bridge hardware,
in which there are some 60 different cpu frequencies available
for cpu scaling, the rapidly fluctuating clock speeds might
get us into trouble--i.e. suspending the machine on one clock
frequency and bringig it back on a different clock frequency?

Does anyone have experience in migrating between hardware
generations... Ivy Bridge -> Westmere and vice versa?

Finally, has anyone run a successful combination of kernel 3.10
or greater and RHEL6/Centos 6/Sci. Linux 6?
(In particular do the stock versions of libvirt and qemu-kvm
play nice with the 3.10 kernel)?
The 2.6.32 kernel that comes with RHEL6/Centos6/Sci Linux 6 is just not
up to dealing with virtualization on Ivy Bridge machines and it
has some trouble on Sandy Bridge too.

Thanks

Steve Timm

 Your "working" screenshot shows a VNC session to a VM deployed in the same

 trying to open connections to VMs in a different host (10.2.2.2). My

Re: [one-users] DHCP

[kerryhall .]

Valentin,

Thank you for the help!

Yes, AFAIK the DNS server is configured with a dynamic zone that is updated
from the DHCP server.

It sounds like the DHCP server in use is Microsoft DHCP. I would like to
avoid using the DHCP API if possible, just because I have no experience in
that area, and seems like a messy solution.

Thinking about this more, here are the desired steps:
1. User spins up vm via web interface.
2. Contextualization sets "DHCP_HOSTNAME" to vm name.
3. DHCP server gives vm an IP address.
4. Sunstone sets the correct IP information in its database.

I can basically do all this manually by
1. Spin up vm
2. edit ifcfg-eth0, setting BOOTPROTO and DHCP_HOSTNAME
3. restart networking

So it sounds like I can write a bash script that takes care of 2. and 3.,
something that runs when the vm is spun up.

However, I don't know how to manually tell Sunstone what the new, correct
IP is. Do you know how I could accomplish that?

I can write a bash or perl script that fixes this manually in MySQLbut
that seems like a Really Bad Idea. :)

I'm surprised that OpenNebula doesn't support DHCP out of the box. Seems
like a common use case. I wonder if I should make a feature request.

Thanks!
Kerry

[one-users] Upgrade 4.6 to 4.8 (beta) - onedb fsck report an error

[Anandharaj Subramaniam]

Hi,

I have followed the documentation to upgrade my test OpenNebula from 4.6.2 to 
the 4.8 (beta 1).  When I run the onedb fsck, I got an error.

[oneadmin@opennebula ~]$ onedb upgrade -v -u oneadmin -d opennebula
MySQL Password:
Version read:
Shared tables 4.6.0 : OpenNebula 4.6.2 daemon bootstrap
Local tables  4.5.80 : OpenNebula 4.6.2 daemon bootstrap

MySQL dump stored in /var/lib/one/mysql_localhost_opennebula.sql
Use 'onedb restore' or restore the DB using the mysql command:
mysql -u user -h server -P port db_name < backup_file


>>> Running migrators for shared tables
Database already uses version 4.6.0

>>> Running migrators for local tables
  > Running migrator /usr/lib/one/ruby/onedb/local/4.5.80_to_4.7.80.rb
  > Done in 0.27s

Database migrated from 4.5.80 to 4.7.80 (OpenNebula 4.7.80) by onedb command.

Total time: 0.27s


[oneadmin@opennebula ~]$ onedb fsck -S localhost -u oneadmin  -d opennebula
MySQL dump stored in /var/lib/one/mysql_localhost_opennebula.sql
Use 'onedb restore' or restore the DB using the mysql command:
mysql -u user -h server -P port db_name < backup_file


undefined method `[]' for nil:NilClass
Error running fsck version 4.6.0
The database will be restored
MySQL DB opennebula at localhost restored.
