[one-users] Hadoop Master/Slave image from MarketPlace

[Manuel Parra]

Hello, I'm trying to deploy images of Hadoop Master/Slave from MarketPlace.
I have create a lot of templates for those images, but when deploy on VMs,
I can't do ssh / ping, etc.

Do those images have a special template with IP address range, or something
??

Thanks in advance!

Maybe the problem is with the nomenclature.

You said you wanted to report the VM is stopped. To OpenNebula that means
that the VM disks and the memory state have been saved back to the system
datastore, plus the networking is cleaned up, etc. That's something that
the VM can't do by itself, so we don't consider the option to report that
from the poll info.

If by stopped you mean that the VM was shut down, then the drivers can
report 'd', and the core will move it to the poweroff state.
In any case, a VM in the suspended or poweroff states can be deleted
without having to resume it first.

At least that's how it works for 4.10, it may be a bit different in 4.6.

 The '-' character indicates a monitoring unexpected error, like when
 the monitoring probes could not parse the output. In this case OpenNebula
 does nothing, the current VM state is kept.
 A state='d' (disappeared) indicates that the monitoring could be done
 (hypervisor is up), but the VM was not found in the list of VMs. In this
 case OpenNebula will set the VM to unknown.

[one-users] Two servers configuration

[Roberto Majadas Lopez]

Hello people:

I've been testing opennebule over few months ago and it's a really
cool solution. I've been testing just in one server but now i'm
testing with two servers. I want to check the possibilites of running
opennebula in something like this:

* Server1:
   - Opennebula Frontend + worker1
   - exports by NFS /var/lib/one

* Server2:
   - Opennebula worker2

In the field of storage there are some different possibilities:
   - Both workers using the server 1 datatastore. Worker1 using
/var/lib/one and worker2 using the exported by NFS
   - Create in both servers a glusterfs and use it as datastore
   - etc etc

Anyone has experience with a similar configuration? any idea or comment?

Thanks :)

Roberto

PD: Please, forget the other incomplete email, gmail betrayed me ;)

[one-users] Duplicate Information from onehost CLI

[Rhesa Mahendra]

Guys,

We use Opennebula 4.10 and we have 8 nodes.
I have problem with sunstone in hosts tab, if i access hosts tab, the 
sunstone is always loading.

if i try use command line, i get duplicate information like this :

MONITORING INFORMATION
ARCH="x86_64"
ARCH="x86_64"
CPUSPEED="2400"
CPUSPEED="2400"
HOSTNAME="node003"
HOSTNAME="node003"
HYPERVISOR="kvm"
HYPERVISOR="kvm"
MODELNAME="Intel(R) Xeon(R) CPU   E5620  @ 2.40GHz"
MODELNAME="Intel(R) Xeon(R) CPU   E5620  @ 2.40GHz"
NETRX=""
NETRX=""
NETTX="x"
NETTX="xxx"
RESERVED_CPU=""
RESERVED_MEM=""

I think this is problem so, the sunstone cannot show the information 
from hosts tabs, from 8 nodes, we have problem in 3 nodes, please help 
me, thanks.
