Hi,

Without the E1000 model, does the VM boot? If so, does it recognise
the NIC if you install the vmware tools?

This may be of help:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1001805

I suggest approaching the problem by creating a Windows VM in VMware
that recognises the NIC, and afterwards creating the same VM through
OpenNebula.

Regards,

-Tino

 Hi Neelaya,

  the frontend and the nodes must share /var/lib/one/datastores. Any
 node can export this share, preferably a NAS system, but if you don't have
 been, you can export it from the frontend.

[cmcc.dylan]

Hi.
  I don't use >= 4.0. But I think the code has a little problem, that is, we 
should add a lock for "get_interfaces" not for "create_bridge".

Hi,


not sure I follow, but given that the rules are idempotent if the bridge 
doesn't exist it will be created, and if it does, it won't.


Have you tried this with ONE >= 4.0 and still fails?

Jaime

Hi，Jainme.
 
  I think curruent codes don't have solved the bug complelely. The key problems 
the the following snippets are executed  parallel.
class OpenNebulaHM < OpenNebulaNetwork
XPATH_FILTER = "TEMPLATE/NIC[VLAN='YES']"
def initialize(vm, deploy_id = nil, hypervisor = nil)
super(vm,XPATH_FILTER,deploy_id,hypervisor)
@bridges = get_interfaces

so bridges variable maybe have the same name bridge. because bridge is a ruby 
instance variable，not a ruby class variable.

Hi everyone！
 
   I find a problem when we create two or more instances on one host at the 
same time，we meet the error "device onebr alreay exists can't create bridge 
with the same name".
   The reason is that instances all try to create their bridge，although they 
check whether or not their birdge is existed. because it's at the same time, 
they all get a result that their bridge is not existed, and then they create it.
   But when they really create, the same bridge has already been created by 
other instances.
 
Has the problem been fixed now？ I use opennebula-3.8.1.
 
   Look forward your answers!

Re: [one-users] Ceph and thin provision

[Campbell, Bill]

Yes, Dumpling supports format 2 images (I think Bobtail 0.56 was the first 
release that did). 

I'll be submitting my modified driver to the development team for 
inclusion/modification (ideally we should be able to select which format we 
want to use, so further modifications would be necessary) and hopefully it 
would be included in the next version. 

In the interim, I can share with you the drivers we are using, but be advised 
this would be UNSUPPORTED by the OpenNebula development/support team. It has 
been working rather well for us though.

Re: [one-users] upload image error

[Tino Vazquez]

Hi,

To upload a VMware image through Sunstone, since it potentially has
more than one file, it has to be contained in a directory. This
directory then needs to be compressed (with tar.gz or bzip2), and then
uploaded to Sunstone.

Is this the process you are currently followed?

Regards,

-Tino

Kenneth, 
The allocation of images consuming the total image size looks to be a bug in 
Ceph:

They've identified, but doesn't look like there's been any movement on it since 
the bug was opened.

I haven't tested much on non-persistent image as I have no use on them unless 
on experiments. Also, I haven't tried any volatile image, sorry. 

A not persistent image is writeable? 

Short answer: NO 

Long answer: Yes, sort of. When you instantiate a non persistent image, nebula 
create a "another disk" in the background temporarily. You can check that on 
when you issue "rbd ls -p one". You'll see something like this. 

one-34 ---> this is the non persistent image disk 
one-34-73-0 > this is the "temporary clone" of the disk when you 
instantiate a VM 
one-34-80-0 -> another VM which uses the non persistent image one-34 

This is why you can instantiate two or more VMs using a non-persistent image. 
If I'm not mistaken, the temporary disk will be destoyed once you shutdown the 
VM from nebula sunstone. But as long as the VM is running, the data is there. 
You can even reboot the VM with non-persistent disk and still have data. You 
lose the data once Nebula destroys VM disk, that is, when you SHUTDOWN or 
DELETE the VM from nebula sunstone. 

As for thick and thin provision, all of my images in ceph are thick, because my 
base image is 25 GB disk from a KVM template and then I imported it in ceph (it 
was converted from qcow2 to rbd). It consumes whole 25GB on my ceph storage. I 
just clone that "template image" every time I deploy a new VM. 

I haven't tried creating a thin or thick provision in ceph rbd from scratch. So 
basically, I can say that a 100GB disk will consume 100GB RBD in ceph (of 
course it will be 200GB in ceph storage since ceph duplicates the disks by 
default).

In several virtualization systems you can have a virtual disk drive:

the virtual machine fills it. 

So I can have a real hdd of 250gb with inside ten virtual thin disks of 1000gb 
each, if they are almost empty. 
I have checked again and ceph rbd are "thin". 

BTW: I thank you for you explanation of persistent/not persistent, I was not

Hi, 

Can you elaborate more on what you want to achieve? 

If you have a 100GB image and it is set to persistent, you can instantiate that 
image immediately and deploy/live migrate it to any nebula node. Only one 
running instance of VM of this image is allowed. 

If it is a 100GB non persistent image, you'll have to wait for ceph to "create 
a copy" of it once you deploy it. But you can use this image multiple times 
simutaneously.

If the DS path does not exist (/var/lib/one/datastores/109), the scheduler
will use the storage reported by the host in /var/lib/one/datastores.

The storage that the scheduler is considering can be seen with   onehost
show 0 -x | grep FREE_DISK.
sched.log should also contain the MB that the VM is requesting from the
system DS.

> Shouldn't the directory be created automatically?

The first deployment will create the dir. From that point, the monitored
storage will be reported in the onedatastore output.

Regards.

[one-users] Opennebula 4.4 - System Datastore cannot be used

[Pascal Petsch]

Hello,

I'm facing a problem when creating a new VM since the update from One 
4.2 to 4.4.

The sched.log tells me the following:

Thu Dec 12 12:24:31 2013 [SCHED][D]: VM 573: Local Datastore 109 in Host 
9 filtered out. Not enough capacity.
Thu Dec 12 12:24:31 2013 [SCHED][I]: VM 573: No suitable System DS found 
for Host: 9. Filtering out host.


Everything worked fine before and there is more than enough space left 
on the disk.

I followed the instructions of the documentation to create a system ds.
This is my configuration of the DS:

DATASTORE 109 INFORMATION
ID : 109
NAME   : system_01
USER   : oneadmin
GROUP  : oneadmin
CLUSTER: Cluster_01
TYPE   : SYSTEM
DS_MAD : -
TM_MAD : shared
BASE PATH  : /var/lib/one/datastores/109
DISK_TYPE  : FILE

...

DATASTORE TEMPLATE
SHARED="YES"
TM_MAD="shared"
TYPE="SYSTEM_DS"

The setup is a single host running one and sunstone.
Shouldn't the directory be created automatically?

I hope you can help me!

Kind Regards

Yes, that is possible. But as I said, all my images were all
preallocated as I haven't created any image from sunstone.

 Yes. It is a basic requirement that all the nodes (frontend +
 hypervisors) should have a oneadmin account, and they should be able 
 to ssh
 passwordlessly from any node to any other node.

Re: [one-users] Ceph and thin provision

[Michael]

This doesn't appear to be the case, I've 2TB of images on Ceph and 380GB 
data reported by Ceph (760G after replication). All of these Ceph images 
were created through the Opennebula Sunstone template GUI.

I see, I misunderstood your question.
The Scheduled Actions table in Sunstone shows two times:
TIME is the requested time
DONE is when the scheduler actually executes the action. But since the
action is asynchronous, the scheduler doesn't know when the snapshot
process ends, just when it is started.

[one-users] Booting stopped VMs a second time after an error cause problem with CDROM link

[Daniel Dehennin]

Hello,

On ONE 4.2, testing why the stop did not work[1]:

1. start a non persistent VM
2. stop it => successfully copied to frontend datastores/0
3. resume the VM, transfer failed => the VM state is back to STOPPED
4. fix the transfer problem[2]
5. resume the VM =>

[TM][I]: Command execution fail: /var/lib/one/remotes/tm/ssh/context

Maybe a clean should be done on host before resuming from STOPPED?

 Hi,

 Please reply to the mailing list as well.

 Yes. It is a basic requirement that all the nodes (frontend +
 hypervisors) should have a oneadmin account, and they should be able to ssh
 passwordlessly from any node to any other node.

 cheers,
 Jaime

Re: [one-users] Ceph and thin provision

[Kenneth]

 

I haven't tested much on non-persistent image as I have no use on
them unless on experiments. Also, I haven't tried any volatile image,
sorry. 

_A not persistent image is writeable?_ 

Short answer: NO


Long answer: Yes, sort of. When you instantiate a non persistent
image, nebula create a "another disk" in the background temporarily. You
can check that on when you issue "rbd ls -p one". You'll see something
like this. 

one-34 ---> this is the non persistent image
disk
one-34-73-0 > this is the "temporary clone" of the disk
when you instantiate a VM
one-34-80-0 -> another VM which uses
the non persistent image one-34 

This is why you can instantiate two or
more VMs using a non-persistent image. If I'm not mistaken, the
temporary disk will be destoyed once you shutdown the VM from nebula
sunstone. But as long as the VM is running, the data is there. You can
even reboot the VM with non-persistent disk and still have data. You
lose the data once Nebula destroys VM disk, that is, when you SHUTDOWN
or DELETE the VM from nebula sunstone. 

As for thick and thin
provision, all of my images in ceph are thick, because my base image is
25 GB disk from a KVM template and then I imported it in ceph (it was
converted from qcow2 to rbd). It consumes whole 25GB on my ceph storage.
I just clone that "template image" every time I deploy a new VM. 

I
haven't tried creating a thin or thick provision in ceph rbd from
scratch. So basically, I can say that a 100GB disk will consume 100GB
RBD in ceph (of course it will be 200GB in ceph storage since ceph
duplicates the disks by default).

 Thanks a lot for your reply. I have one more doubt. Should I have to

 that it has to be done for the hosts.

Re: [one-users] device onebrxxxx alreay exists can't create bridge with the same name

[Jaime Melis]

Hi,

not sure I follow, but given that the rules are idempotent if the bridge
doesn't exist it will be created, and if it does, it won't.

Have you tried this with ONE >= 4.0 and still fails?

Jaime

Re: [one-users] Ceph and thin provision

[Mario Giammarco]

In several virtualization systems you can have a virtual disk drive:

-thick, so a thick disk of 100gb uses 100gb of space;
-thin,  so a thin disk of 100gb uses 0gb when empty and starts using space
when the virtual machine fills it.

So I can have a real hdd of 250gb with inside ten virtual thin disks of
1000gb each, if they are almost empty.

I have checked again and ceph rbd are "thin".

BTW: I thank you for you explanation of persistent/not persistent, I was
not able to find it in docs. Can you explain me also what a "volatile disk"
is?
A not persistent image is writeable?
When you reboot a vm with a not persistent image you lose all datda written
to it?

Thanks again,
Mario
