[one-users] [Fwd: Re: Opennebula development question]

[Daniel . MOLDOVAN]

Thanks to all for the answers.

And i have a question for opennebula developement. Why in
/one/tm_commands/ssh/tm_context.sh, the temporary directory is
TMP_DIR="$ONE_LOCATION/var/$DST_HASH" ? Should not be /tmp/$DST_HASH?
Because usually oneadmin does not have access to create folders in var in
the case opennebula is installed system wide as in my case(as a result
from express install).

Regards,
Daniel

Re: [one-users] Source RPM package

[Pham Kim Long]

Actually I was asking for the source package, as I need to fix some issues I 
found with the VMware driver.

Thanks

Re: [one-users] VM Templates

[Ruben S. Montero]

Hi Luca,

DRIVER attribute is not included in the last release of OpenNebula 2.0 It is
in the one-2.0 branch. You can download it form the fir repo, the fix will
be distributed in the next maintenance release (at the end of this month)

Cheers

Re: [one-users] VM Templates

[Luca Lorenzini]

@Upendra Moturi: the setting of the vnc port is based on the VMID and it's
unique. Also i havent any other applications or vms using vnc.

I think i found the problem: I'm using qcow2 image format to save disk space
and I noticed that the DRIVER attribute is discarded in deployment file
creation and i'm not able to use qcow2 format for my images. Without this i
cant use images created with backing_file either. I put the  by hand in the deployment file and deploy it
manually and the image boot.
To do this i left my "not-booting-vm" running so the link to the image wasnt
deleted, i change few things in the deployment.0 file (the name, the vnc
port, and i've add the driver tag) and used "virsh create deployment.0"
command. The vm works fine and use the image with backing_file option.

I hope this feature will be fixed asap!

Here my template, deployment file generated by opennebula, the correct one,
and the virsh dumpxml output.

I guess you have tried including the ip in the NIC section of the VM
template? And had a look
to http://opennebula.org/documentation:rel2.0:vgg

NIC = [
  network = "name_of_the_virtual_network",   #Optional, XEN, KVM
  ip  = "ip_address",#Optional, XEN, KVM
  bridge  = "name_of_bridge_to_bind_if", #Optional, XEN, KVM
  target  = "device_name_to_map_if", #Optional, KVM
  mac = "HW_address",#Optional, XEN, KVM
  script  = "path_to_script_to_bring_up_if"] #Optional, KVM

You might need to use the contextualization feature as well:

Another way may be to configure your guests directly with the fixed IP
address you want, but this is not so elegant as letting opennebula do it
for you, of course.

Not too difficult but it can get tricky the first time. You may need to
look on
http://wiki.libvirt.org/page/Networking
if you're using kvm, to check that libvirt is correctly setup for that.

Good luck,

[one-users] Virtual Machine Static IP Address

[Daniel . MOLDOVAN]

Hy,

Is there any method of assigning a fixed/static IP to a virtual machine? I
have tried anything, even creating a virtual network with only one IP as
lease like below and assign this network to the virtual machine in the vm
template.

NAME = "VM2_net"
TYPE = FIXED
BRIDGE = virbr0
LEASES = [IP=192.168.122.23]

Nomather what i try, the virtual machine will always get a random IP
located in the subnet of the virbr0 bridge. Although using onevm show, the
IP i have requested is reported as assigned, inside the virtual machine
things are different.

Can there be issues regarding the host/guest OS? I am running CentOS as
host and currently experimenting with Ubuntu JeOs and Desktop editions as
guest systems.The network configuration inside the hosts states that the
IP is assigned by DHCP.

P.S. And just of curiosity(i am new to bridging/networking) how difficult
it is to perform some bridging or connection in order to be able to ping 
the virtual machine from any opennebula node or client, not just from the
current host of the virtual machine?

Thank you,
Daniel

The Requirements and rank expressions are given in the VM description file
(template), so  they can be configured per VM instance. However when using a
cloud interface, the user can not specify these attributes and so are
defined by the cloud administrator per VM type.

Both scenarios can be implemented.

[one-users] Match-making scheduler question

[Adrian Muresan]

Hi,

I'm writing a survey on Clouds for research purposes. I have some questions 
related to the match-making scheduler that OpenNebula uses:

1. it's not clear for me if the placement policies can be configured per VM 
type or per VM instance, could you clarify this?

2. are the placement policies configurable per cloud client or for the whole 
cloud platform?

3. is it possible to configure the policies in such a way as to distribute a 
client's VMs across the physical hosts in such a way as to reduce the 
probability of platform failure as a result of hardware failure? Is this 
do-able without modifying the source code of OpenNebula?


Thanks very much,

Adrian Muresan

[one-users] Source RPM package

[Pham Kim Long]

Hi

Is there a source RPM package available for ONE 2.0? I looked at
http://dev.opennebula.org/projects/packages/files
and found only 2.0 beta source.

Thanks OpenNebula team for the great work.

Re: [one-users] VM Templates

[Upendra Moturi]

Can you check libvirt logs of host.
Generally the below message comes when there is address already in use(vnc
port).
error: monitor socket did not show up.: Connection refused
If change the vncport and try.

Re: [one-users] VM Templates

[Daniel . MOLDOVAN]

Hy,

I have encountered the same problem. Do not specify Kernel because this is
mainly used in conjunction with the XEN hypervisor and it indicates the
physical path to the HOST kernel used to boot the virtual machine, not of
the kernel inside the VM. So if the Host is using Ubuntu, only the Ubuntu
distributions can be loaded by using the Kernel attribute.

And about the no bootable device found, i have avoided it only by:
- defining also Image disk
 example: DISK = [type=cdrom ,
source=/home/utcn/Downloads/jeos-8.04.3-jeos-i386.iso, target=hdb]
- stating that ROOT=hdb and booting from the cdrom. From it i could
install the linux distribution on the "disk" device and then use it as a
normal boot device.


I think that because the virtual disk was not created by opennebula( i
used AQUEMU GUI), it did not recognized it properly in order to boot from
it.

P.S. If anywone has a more elegant solution to this "no bootable device
problem" problem fell free to share.

Thanks,
Daniel

Try to comment the "GRAPHICS " stuff Do it works for this case??
