hi, You are right, TARGET cannot be set in the image template, but you can set the DEV_PREFIX, that should be enough to achieve a working deployment file. I investigate more on the subject, finally the conclusion is that Xen in HVM mode can't handle more than 4 devices, that's why it worked with xvdc or xvdd.

Re: [one-users] Changes in 3.0 template network syntax
Hi Steve, On Wed, Sep 14, 2011 at 4:39 PM, Steven Timm t...@fnal.gov wrote: So two questions--why did they change the syntax? It is easier for users to remember the name of the network than the ID of the network particularly since users now can't do onevnet list, and it renders all of our existing templates (dozens of them) broken and we will have to change them. Some users requested to let new resources use repeated names. This makes sense in deployments with a large number of users, or in a multi-tenant scenario. The drawback is that users are forced to use the ID in VM templates, but it seemed a reasonable requirement. Users can still use the 'onevnet list' command. By default, they can list their vnets with the 'm' (mine) option, and the vnets in their group with 'g' (group). If you need all users to be able to list any existing vnet with the 'a' (all) option, like users in the oneadmin group can do, then you need to set the following ACL: $ oneacl create * NET/* INFO_POOL+INFO+USE And second, why can not the user pick the network they want.. is there some ACL that has to be set now? If so, where? Users can list, show and use by default any vnet they own, and any public vnets in their group. You can also set an ACL rule with the INFO+USE permission for any other vnet; more information is available here [1]. You can forget about ACL and permissions if all users are in the default users group, and create all resources in that group (not in oneadmin group). Steve Timm Best regards.

After building it I have installed it using install.sh as follows: # ./install.sh -u oneadmin -g cloud Everything went well and I ended up with a fresh OpenNebula install. I have configured the MySQL databases credentials in /etc/oned.conf and started oned.

So far so good, everything works as expected. What I want to do next is to update the debian image (apt-get update apt-get upgrade) and save it as a new image. Said and done. I first start the Debian VM, update it and then using onevm saveas I want to save the VM disk with ID 0 under a new name. # onevm saveas 5 0 debian-upd1 I mention that I ran the above command while the Debian VM was on. As far as I understand from documentation this is not a problem but the contents of the image are only created after the VM is shutdown gracefully (using onevm shutdown). So I did just that. # onevm shutdown 5 # onevm list ID USER GROUPNAME STAT CPU MEMHOSTNAME TIME 5 oneadmin oneadmin one-5shut 0 0K node02 00 00:09:18 I verify if the image is created using oneimage. I have double checked listing the SOURCE and it is there. # oneimage show 2 IMAGE 2 INFORMATION ID : 2 NAME : debian-s-upd1 USER : oneadmin GROUP : oneadmin TYPE : OS REGISTER TIME : 09/15 16:15:06 PUBLIC : No PERSISTENT : No SOURCE : /var/lib/one/images/b92349a9f4ad479facf95f6706777d11 SIZE : 721 STATE : rdy RUNNING_VMS: 0 IMAGE TEMPLATE DEV_PREFIX=hd NAME=debian-s-upd1 SOURCE=- The problem. The Debian VM is gone, it is not listed anymore. onevm returns empty list. The Debian VM was the only one active. Is this normal behavior if you save the only disk the VM has?

Re: [one-users] Opennebula DB upgrade issues:
Hi,
The sequel gem should be installed by the install_gems script [1].
Did you get any error message during the installation?
Regarding the Mysql error, it is a bug. I have opened a ticket [2].
Please change in /usr/lib/one/ruby/onedb/2.0_to_2.9.80.rb the following:
- @db.fetch(SELECT COUNT (ip) FROM old_leases WHERE (oid=#{oid} AND
used=1)) do |r|
- total_leases = r[:COUNT (ip)]
+ @db.fetch(SELECT COUNT(ip) FROM old_leases WHERE (oid=#{oid} AND
used=1)) do |r|
+ total_leases = r[:COUNT(ip)]
It looks mysql doesn't like the space before the parenthesis.
I have also found a typo in /usr/lib/one/ruby/onedb/onedb_backend.rb , and
onedb restore won't work with mysql unless you change:
create_cmd = mysql_cmd+-e 'CREATE DATABASE IF NOT EXISTS #{@db_name};'
- rc = system(create_cnd)
+ rc = system(create_cmd)
if !rc
raise Error creating MySQL DB #{@db_name} at #{@server}.
end
Thank you for the feedback, it will be solved in the final release.
Carlos.

I tried to upgrade Mysql db from V2.0 to 2.9.80 using onedb upgrade –v
command for updating db to support Opennebula 3. But ran in into issues
described below
Does it need some more mysql component or some fix in onedb upgrade process
?
Thanks

[one-users] IMAGE_REPOSITORY_PATH and OpenNebula 3
Hi All, With ONE 2.2, we used the IMAGE_REPOSITORY_PATH config value to point to a separate store for image files that was outside of the $ONE_LOCATION/var/ directory. It appears that with the new ONE_IMAGE MAD, this config value is gone, so we can't now add new images into the system as we had before. Right now we are using symlinks to fix this, but that's not a great solution. What is the appropriate upgrade in ONE 3 to match this functionality from ONE 2? Thanks, Rob -- Robert E.

Re: [one-users] IMAGE_REPOSITORY_PATH and OpenNebula 3
Hi, OpenNebula 3.0 features a new image repository based on drivers. Currently we are shipping one based on files (images supported by a regular file). You can take a look at it under: $ONE_LOCATION/var/remotes/image/fs There you will see scripts for the repo operations, to copy (cp), move (mv), delete (rm) and create (mkfs). There is also a configuration file $ONE_LOCATION/var/remotes/image/fs/fsrc Modify IMAGE_REPOSITORY_PATH to point to your repo directory. You may be also interested in the other scripts to fine tune your deployment Cheers Ruben On Thu, Sep 15, 2011 at 6:35 PM, Robert Parrott parr...@seas.harvard.eduwrote: Hi All, With ONE 2.2, we used the IMAGE_REPOSITORY_PATH config value to point to a separate store for image files that was outside of the $ONE_LOCATION/var/ directory.
