Re: [one-users] Is it OK for VM migration between two physical hosts when the home folders of these two hosts are different?

[Qiubo Su (David Su)]

Dear OpenNebula Community,

Thanks for your help.

If it is failed when start a VM, how to debug to sort out the cause for the
error?

Thanks,

Re: [one-users] datastore log info missing from oned.log in v4.2

[Gary S. Cuozzo]

Then it seems that this has changed since the 3.8.x series.  I use log_debug 
script function to log various messages in my drivers.  I have my log level set 
to DEBUG in conf file.  I used to see those messages, as I would expect, unless 
I changed the log level to something above DEBUG.  The messages were logged 
regardless of the outcome of the script.

It seems that if that is no longer the case, then the log facility can't be 
used for anything other than error conditions and having DEBUG, INFO, etc. is 
not very useful anymore.

Maybe I'm missing the point of the feature, but it definitely did not work this 
way before and was something I relied on for certain things.  I'm now 
overriding the log_debug function locally in my script and writing the output 
to my own log file.  That is not as nice because now the log entries are not 
intertwined with other events which are happening in the oned.log file.

IMO, any message should be written to the file based on the configured log 
level.

Let me know your thoughts.

Thanks for the reply,
gary

Attaching/Detaching using a IDE controller is not supported in VMware
ESX.This is documented in the new development documentation, platform
notes for VMware ESX [1]:

8<

to accomplish disk hotplugging and nic hotplugging (ignore the first
bullet for the latter)

disks need to be attached through SCSI, so their images should have a
DEV_PREFIX=“sd”
VM template that will permit SCSI disk attaches afterwards needs to
have an explicitly defined SCSI controller:

RAW=[TYPE = "vmware",
 DATA = ""]

to use SCSI disk based VMs, it is usually a good idea to explicitly
declare the PCI bridges. This can be accomplished with the following
added to the VM template:

 FEATURES=[PCIBRIDGE="1"]

to accomplish hot migration (through vMotion)

My hook job is ok regarding vm user_template  update, I tried with and
without VM_SUBMIT_ON_HOLD (thanks for the hint), but I have the same
issue, my user_template variables are not set in the context.sh file.

user_template is not set by itelf in the vm context file, only the
context. But in my context, I add variables that refer to USER_TEMPLATE
(but it is right that there are not set in first place, only after
hooks). So it seems that we can refer to USER_TEMPLATE var, but only if
there are predefined, not added in a hook (template not
regenerated/calculated).

the best would be to have user_template vars added to the context.sh
file in addition to the one in the vm template, AFTER the hooks.

Re: [one-users] updating TEMPLATE from hooks with onevm update

Bonjour Olivier,

I think there are two issues in your question.

First, yes, you can use the VM CREATE hooks to inject or change the
USER_TEMPLATE attributes by issuing the onevm update action. To prevent VMs
from being deployed before the hooks has run, you can set VM_SUBMIT_ON_HOLD
= "YES", and have your hook do a onevm release at the end of its execution
for the scheduler to pick and deploy the VM. This will make sure that when
the VM is deployed, the template contains all the attributes you wanted.

You can also do some extra sanitization / filtering and not allow the VM to
be deployed if contains some missing attributes, etc. by not calling the
onevm release at the end.

This works very well for us. In fact, we do some heavy stuff in the hooks,
such as attaching additional IP addresses, attaching or detaching disks,
etc. dynamically according to external sources, such as the OpenNebula user
template (but also external databases, CRM, etc.)

Perhaps that's the real problem here... I'm not very familiar with
context.sh script. Is the entire VM template available (including the
USER_TEMPLATE) or only the CONTEXT section?

[one-users] resize VM dialog is better, but there is a problem with VCPU

[Rolandas Naujikas]

Hi,

After

resize dialog works better, but for VCPU there is logic error. In 
leftmost position VCPU value should be 1 at least, 0 - is not valid 
value. Maximum value should be also bigger 16 at least.


Also 0 value is not meaningful for CPU and MEMORY.

Regards, Rolandas

P.S. Of cause all those values could be entered manually.

 Hi,

 When the VM is created, the template contents are parsed and stored
 in VM/TEMPLATE. All the extra unknown attributes are stored in
 VM/USER_TEMPLATE. You can see this with the onevm show -x command.
 The onevm update action only allows to edit the USER_TEMPLATE
 attributes, and as you described, the create hook is triggered after
 the VM has been correctly created.

 I don't see any easy way to make your work flow fit into OpenNebula.
 Could you elaborate a bit more on your use case?

We do not want to push info from VM to open nebula or other systems, but
push some local/dynamic information to the VM (at startup), via the
context, so that the VM can initialise with those dynamic data.

 I'm assuming you want those two variables to end in the context
 section of the VM. In that case the preferred way to do so would be
 to have a VM Template for each Image, and in there set the needed
 variables.

  SSH_PUBLIC_KEY="ssh-rsa.."
  XGRID_PWD="xxx"
  

  In my image template, I have set:

  SSH_PUBLIC_KEY $USER[SSH_PUBLIC_KEY]
  XGRID_PWD $USER[XGRID_PWD]


  But in the VM template, I do not see any of those variable.

  It would seem that user template attributes are created *after*
  the vm template generation.

  Any idea  ?

  Thanks

Re: [one-users] different authentication methods for different interfaces

Hi,

That is not supported, only one auth driver can be set for each user. We could consider adding 
support for more than one drivers, but that would require a bit of development and I can't think 
of any immediate workaround.


By the way, I know this is not what you asked, but x509 is also supported for 
the cli [1].
Carlos, thanks a lot for reply! Then I will probably consider the use of x509 authentication method 
for both cli and sunstone.


Best regards,

STDERR is only logged when the action is not successful, maybe that is

A basic use case is to generate a unique password for a web

a hook and send the password to the user by mail (until here, this is
fine). The generated password is also in the VM context/template so
that it appears in the context.sh of the VM. At startup, a specific

with the password provided.

The above example could be managed directly in the VM, without specific
contextualization, but there are cases where some variables could be
user dependent, so those variables would need to be set dynamically on
opennebula server side.



Olivier


I'm assuming you want those two variables to end in the context
section of the VM. In that case the preferred way to do so would be
to have a VM Template for each Image, and in there set the needed
variables.

I logged all sessions on the memcached server and no connection was made
when I started apache / tried to login ... :sessions wasn't initialized
properly. I fixen that and know it's working. I must have been sleepin'

Re: [one-users] Is it OK for VM migration between two physical hosts when the home folders of these two hosts are different?

[Carlos Martín Sánchez]

Hi,

The oneadmin home is not relevant, what is required is that the datastores
are mounted in the same location [1]. DATASTORE_LOCATION is defined in
oned.conf, and by default it is /var/lib/one/datastores.

Re: [one-users] updating TEMPLATE from hooks with onevm update

[Carlos Martín Sánchez]

Hi,

When the VM is created, the template contents are parsed and stored in
VM/TEMPLATE. All the extra unknown attributes are stored in
VM/USER_TEMPLATE. You can see this with the onevm show -x command. The
onevm update action only allows to edit the USER_TEMPLATE attributes, and
as you described, the create hook is triggered after the VM has been
correctly created.

I don't see any easy way to make your work flow fit into OpenNebula. Could
you elaborate a bit more on your use case?

I'm assuming you want those two variables to end in the context section of
the VM. In that case the preferred way to do so would be to have a VM
Template for each Image, and in there set the needed variables.

Let's try to find out the problem:
* Check in "/var/log/one/sunstone.log" that the memcache is indeed enabled.
Note that it is "memcache" and not "memcached":
 :sessions=>"memcache",
* Try removing the cookies from your browser, maybe firefox is trying to use 
the old sinatra session and sunstone-server cannot find it in memcache.

Hope this helps

Re: [one-users] Re; Snapshots ... rendering bug on Placement ...

[Daniel Molina]

Hi Gareth,

Could you send us the output of onevm show -x when this value is shown in
Sunstone. Are the server and client time synchronise?

Cheers

ssh public key is installed for root password. Are you trying to connect to 
root user with the correct private key?

Re: [one-users] different authentication methods for different interfaces

[Carlos Martín Sánchez]

Hi,

That is not supported, only one auth driver can be set for each user. We
could consider adding support for more than one drivers, but that would
require a bit of development and I can't think of any immediate workaround.

By the way, I know this is not what you asked, but x509 is also supported
for the cli [1].

Let's try to find out the problem:

Note that it is "memcache" and not "memcached":

Hi,


Could you try installing the nokogiri gem, and restarting sunstone-server after 
that

Re: [one-users] How do i know the cluster's datastore's capacity?

[Kenneth]

 

You can of course. But it is up to you to monitor. And using storage
on different hosts will cause the VMs to be copied via scp which is
pretty slow. 

Another way to have a large storage is to remove other
drives on the nodes (or use small drives in them) and then plug big
capacity drives on the main NFS node. I mean put everything on the host
A and let other have a small hard drive just enough for the OS itself.

That's because you are not using a shared folder for all hosts. A better
way to do it is to make the /var/lib/datastore/1/ folder on the sunstone
as a NFS folder and then mount it all other hosts on the same location
/var/lib/datastore/1/. This will enable you to do live migrations and
very fast deployment of vms.

Thanks for replay!
But if I use a shared folder ,such as /var/lib/datastore/1/ on host A  and 
mount it on all hosts in a cluster. the whole storage capacity is very 
small,Opennebula can't use other hosts's disk space.?

Re: [one-users] how could i move the exist vms to nebula?

[André Monteiro]

Mainly depends on the amount of VMs, but the simplest way is to import as
an Image, providing the VM disk filepath, and then build an adequate
template for it. Don't forget to make the image persistent if you want to
preserve changes.

I have two hosts in a cluster, every host has 100GB space for
