[one-users] How opennebula use vmware drivers addon to manage esx/esxi4.1?

[张光鹏]

Hi:
The VMware Drivers Addon enables the management of an OpenNebula cloud based on 
VMware ESX and/or VMware Server hypervisors. 

Is VMware Server means vCenter server?

I read the document(http://www.opennebula.org/documentation:rel3.0:evmwareg ), 
i found it introduced the configuration of esx. But my esx&esxi hosts are 
managed by vCenter server , should it work if i follow the comment -"When using 
VMware Server, the connection string set under LIBVIRT_URI needs to have its 
prefix changed from esx to gsx." I mean some more configuration of how connect 
to vCenter server should be metioned.
 
How could I configure this file-"/etc/one/vmwarerc" to connect to vCenter ?

Could someone give me some guidance?

Thanks All !
Best Regards

[one-users] x509 sunstone

[Faarooq Lowe]

It appears that the x509 authentication doesn't work with sunstone.  We 
we had to change :core_auth" to cipher as opposed to x509.  Is there a 
way to patch this.

[one-users] core_auth in sunstone

[Faarooq Lowe]

What is the core_auth setting for in sunstone-server.conf?  There isn't 
any reference to it in the documentation.


Also when we launch sunstone-server there is reference to a user.  Which 
user is used for sunstone and where is that user set?

Check the permissions on the folder of the image repository, as far as 
I know, at least oneadmin:cloud should be able to write there.

Re: [one-users] error status on disk image

[Carlos Martín Sánchez]

Hi,

I assume you are using the 3.1 development version.
This is a new security feature to prevent users from registering any file
readable by oneadmin.

/var/lib/one is by default a restricted directory, you can configure the
behaviour in /var/lib/one/remotes/image/fs/fsrc, check the Image Repository
documentation for more info [1].

You can also check the new features and main changes in the compatibility
guide [2]

Regards.

Register the hard disk image in the image repository (with

I'm using shared.

But if I use the image repository, it will *copy* my image at least once, right?
My images are very big.>500GiB.


Yes, it will be copied, unless you use NFS or any other shared 
storage for the images repository. Using a registered image is 
the only chance for OpenNebula to know that a certain image is 
being used by a VM. This will be updated in the images table in 
the database. OpenNebula does not care about a more then once 
used path to a disk in the VM template.

Re: [one-users] Problem in network from fresh install opennebula 3

[Carlos Martín Sánchez]

Hi,

It looks like for some reason the LEASES attributes weren't processed. If I
create a vnet from this template:

$ cat fixed
BRIDGE=virbrCLOUD
LEASES=[ IP=84.21.173.192, MAC=02:fe:54:15:ad:C0 ]
LEASES=[ IP=84.21.173.194, MAC=02:fe:54:15:ad:C2 ]
NAME=red1
TYPE=FIXED

The xml shows the two LEASES inside VNET/TEMPLATE/ and VNET/LEASES [1].
Can you reproduce this error? Is there anything in your template file that
might cause the parser to fail?

sunstone
ERROR   


TIMESTAMP   Mon Dec 12 14:07:32 2011
MESSAGE 	Error copying image in the repository: Not allowed to copy

oneadmin is the owner of /var/lib/one/templates/ directory.

[one-users] Instantiating Multiple VMs from Template with Name

[Stefan Dietrich]

Hi,

I`m running an OpenNebula 3.0 installation build from source on 
Scientific Linux 6.1 x64.
I have a problem instantiating multiple VMs from a template with the 
name set:


1) Instantiating multiple VMs from templates within Sunstone adds a 
number after the name of the VM, e.g. 'test_01', 'test_02', 'test_03'. 
Is it possible to change the suffix from the underscore to a normal dash 
(test_01 -> test-01)?


2) If I try to instantiate multiple VMs from CMD line with 'onetemplate 
instantiate 3 -m 2 -n test' every VM gets the name 'test' and not 
'test_01', 'test_02'.

This behaviour differs from Sunstone, which I had not expected.
Is this a bug or a feature?

I hope somebody has a solution for this :)

Regards,
Stefan

[one-users] iscsi target as a guest disk

[Tengvall, Ilkka (NSN - FI Espoo)]

Hi,

I'm new to Open Nebula, and have some questions. First one would be
about iscsi support. I can't find any reference from oned documents
itself about iscsi. Is it possible to configure guests  using iscsi lun
from remote server as a os block device?

I have done it using libvirt, so it works, but how to map this to oned
configs?

another way which would also work would be booting kernel directly or
via ipxe and give it iscsi as a root device. Both of those work too.

Is there a way to do this in oned?

I found an old related posting here, but I don't know if it ever led to
anything:

Re: [one-users] Announce 3.0 packages for SUSE

[Jaime Melis]

Hello Robert,

thanks a lot for updating the packages, and thanks a lot for developing the
new systemd scripts, we will include them in OpenNebula's source code.

Regards,
Jaime

[one-users] Scheduler and required memory/cpu

[Tomáš Nechutný]

Hello,

My computer has 4GB of physical RAM (+swap). This computer is also
only OpenNebula host. I created 3 VMs with 2GB specified in template
(without REQUIREMENTS). However the scheduler deploys only 1 VM. This
page http://www.linux-kvm.org/page/Memory sates:

> The qemu/kvm process runs mostly like a normal Linux program. It allocates

I think that it should be possible when there is no ohter host.

This is probably related to http://dev.opennebula.org/issues/846.

Re: [one-users] Opennebula 3.0 accounting tools problem on ubuntu 10.04

[Javier Fontan]

Hello,

Can you check that oneacctd is running?

Also we are having some problems with oneacctd daemon and mysql
databases and we are working to solve this. Meanwhile it would be
better that you use a sqlite database to keep the accounting records.

Bye
