[one-users] Need Help please
Dear Sir/ Madam, I am new to the OpenNebula, and i have downloaded the OpenNebula 2.0 and i would like to use it to build my own cloud, also i would like to know more about the public and the hybrid clouds in order to know how to work with them easily. So would you tell me or even pass me the manual documentation for the codes required to build such cloud(s). And if there are any tutorials to learn me step be step to do so, this will be fine to me. Thank you, And i would be grateful if you replied me back. Mohab Hassan ElNaggar. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

Re: [one-users] Express Installation Script.
Hi, The scripts under /usr/lib/one/remotes are reponsible for the VMM and IM actions. You have to copy them because they are by default copied to /tmp which is generally not persistent after reboot. The default path of these scripts has been changed to /var/tmp in order to avoid this issue and in the upcoming 2.0.1 that will be fixed. If you don't want to wait to the next release follow this thread where we previously discussed this problem: http://lists.opennebula.org/htdig.cgi/users-opennebula.org/2010-October/003102.html regards, Jaime On Wed, Nov 10, 2010 at 1:32 PM, KING LABS kinglabs...@gmail.com wrote: Thats a good thing to know, Once again thanks Daniel for helping me with immediate solution.

Re: [one-users] Express Installation Script.
I am sorry. I haven't said that 755 are the wrong permissions. Just that being new using opennebula i have encountered some permission denied errors and by making the folder world-writable i have avoided them. I have just mentioned as a quick fix to give everybody access to /var/lib/one. I assume my problem originated from the oneadmin user being created without necessary access rights. Because oneadmin also needs write permissions and i think(excuse me if i am wrong) 755 means read-only for anyone other than root. So my oneadmin user created from the install script does not have write access needed for every opennebula operation as the one.db and virtual machines files are there(images and deployment files). But i insist, this might just be due to an incorrect installation process performed by me and not due to incorrect access rights. Regards, Daniel Hello, thank you both for reporting these issues.

Re: [one-users] tm_common.sh.... typo??
I have made a change in 0eb75b414fe0bc6a829b8b24b0f59b80ed1513e7
(branch bug-389) that sets $SED variable with different values for
linux or anything else. Tell me if that seems correct, I think it is
the most straightforward way to fix the problem.
On Wed, Nov 3, 2010 at 6:30 PM, Tiago Batista tiagosbati...@gmail.com wrote:
During normal operation, the error is not triggered but when I was
experimenting with zfs-fuse I was able to trigger it.
I will try to demonstrate the problem with an interactive shell...
If i use the following function (note the \+ escaping) it works as
expected:
function fix_dir_slashes {
dirname $1/file | sed -e 's/\/\+/\//g';
}
If however I use the -E switch, for some reason it fails as the
equivalent gnu switch is -r I think.
$ function fix_dir_slashes { dirname $1/file | sed -e 's/\/\+/\//g'; }
$ fix_dir_slashes /usr/bin//drunk
/usr/bin/drunk
$ function fix_dir_slashes { dirname $1/file | sed -E 's/\/\+/\//g'; }
$ fix_dir_slashes /usr/bin//drunk
sed: invalid option -- E
(...)
I later found out that this is implementation dependent.
The behavior above is from sed 4.1.5 on a scientific linux (rhel based)
system.
On my gentoo desktop, using sed 4.2.1 I do not get an error, but a
silent fail to perform the substitution (unless I remove the \+
escaping, efectively using the regexp from the file):
$ function fix_dir_slashes { dirname $1/file | sed -E 's/\/\+/\//g'; }
$ fix_dir_slashes /usr/bin//drunk
/usr/bin//drunk
$ function fix_dir_slashes { dirname $1/file | sed -E 's/\/+/\//g'; }
$ fix_dir_slashes /usr/bin//drunk
/usr/bin/drunk
$ function fix_dir_slashes { dirname $1/file | sed -e 's/\/\+/\//g'; }
$ fix_dir_slashes /usr/bin//drunk
/usr/bin/drunk
At the moment this does not qualify as a bug for me, as all the linux
systems I know do not fail when paths with multiple slashes are used,
and the problem with the -E was never triggered with the default tm_nfs
scripts.
After searching some more and comparing the bsd and the gnu versions of
sed, I think I may have a solution that works on both platforms (in fact
the one above!) As I do not see the need for extended regular
expressions to perform such a simple replacement when escaping the +
char would solve it...
While at it, I propose that the usage of the $SED variable set above,
therefore defining the function as:
function fix_dir_slashes { dirname $1/file | $SED -e 's/\/\+/\//g'; }
Can you try this on BSD sed as I do not have a BSD shell at the moment?
Tiago

Hello,
We are using -E as BSD version needs that parameter for this regexp to
work and in our tests was working also on linux. Can you tell us what
is the error. Is it sed that does not recognize that command or does
not perform the intended task?

Hello all
From tm_common.sh:
# Takes out uneeded slashes. Repeated and final directory slashes:
# /some//path///somewhere/ - /some/path/somewhere
function fix_dir_slashes
{
dirname $1/file | sed -E 's/\/+/\//g'

Should this be (notice the sed argument)?
# Takes out uneeded slashes. Repeated and final directory slashes:
# /some//path///somewhere/ - /some/path/somewhere
function fix_dir_slashes
{
dirname $1/file | sed -e 's/\/+/\//g'
}
I have looked for it, but found no documentation on the -E argument.
Note that with the tm_nfs drivers this is not an issue (i think...),
but for some reason, when building transfer driver similar to that
found in
http://mperedim.wordpress.com/2010/09/26/opennebula-zfs-and-xen-%E2%80%93-part-2-instant-cloning/
this becomes visible as I do call this code...

[one-users] Creating VMs images in CentOS
Hello, I'm using opennebula with CentOS 5.5 + Xen but i am not sure about the right way of creating images. Example, if i want to create a VM to run CentOS, which steps should i do? I saw that to create Xen domU you can use, for example: virt-install \ --paravirt \ --name webserver01 \ --ram 512 \ --file /vm/example.img \ --file-size 10 \ --nographics \ --location http://mirrors.kernel.org/centos/5.3/os/x86_64/ Is this the correct way of creating it? Them after installing via xm console i should transfer this to frontend and create a configuration file for image, deploying it at opennebula?

Re: [one-users] Making scheduler allocation aware
Hi Javier
Thanks for the inputs but I came across another problem while testing:
If opennebula receives multiple vm requests in a short span of time, the
scheduler might take decisions for all these vms considering the host
monitoring information available from the last monitoring cycle. Ideally,
before processing every pending request, fresh host monitoring information
has to be taken into account as the previous set of requests might have
already changed the host’s state. This can result in over committing when
host is being used close to its full capacity.
*Is there any workaround which helps the scheduler to overcome the above
problem ?*
steps to reproduce the problem scenario:
Host 1 : Total memory = 3GB
Host 2 : Total memory = 2GB
Assume Host1 and Host2 have same number of CPU cores. ( Host1 will have a
higher RANK value )
VM1: memory = 2GB
VM2: memroy = 2GB
Start VM1 and VM2 immediately one after the other. Both VM1 and VM2 will
come up on Host1. ( Thus over committing )
Start VM1 and VM2 with an intermediate delay of 60sec. VM1 will come up on
Host1 and VM2 will come up on Host2. This is true because opennebula would
have fetched a fresh set of host monitoring information in that time.

Hello,
It looks fine to me. I think that taking out the memory the hypervisor
may be consuming is key to make it work.

Yes we are using KVM and OpenNebula 1.4.
We have been having this problem since a long time and we were doing all
kinds of validations ourselves before submitting the request to
OpenNebula.
(there should be enough memory in the cloud that matches the requested
memory there should be atleast one host that has memory requested
memory
) We had to do those because OpenNebula would schedule to an arbitrary
host based on the existing logic it had.
So at last we thought that we need to make OpenNebula aware of memory
allocated of running VM's on the host and started this discussion.
Thanks for taking up this issue as priority. Appreciate it.
Shashank came up with this patch to kvm.rb. Please take a look and let us
know if that will work until we get a permanent solution.
$mem_allocated_for_running_vms=0
for i in `virsh list|grep running|tr -s ' ' ' '|cut -f2 -d' '` do
$dominfo=`virsh dominfo #{i}`
$dominfo.split(/\n/).each{|line|
if line.match('^Max memory')
$mem_allocated_for_running_vms += line.split(
)[2].strip.to_i
end
}
end
$mem_used_by_base_hypervisor = [some xyz kb that we want to set aside for
hypervisor]
$free_memory = $total_memory.to_i - ( $mem_allocated_for_running_vms.to_i
+
$mem_used_by_base_hypervisor.to_i )

Hello,
Sorry for the delay in the response.
It looks that the problem is OpenNebula calculating available memory.
For xen = 3.2 there is a reliable way to get available memory that is
calling xm info and getting max_free_memory attribute.
Unfortunately for kvm or xen 3.2 there is not such attribute. I
suppose you are using kvm as you tell about free command.
I began analyzing the kvm IM probe that gets memory information and
there is a problem on the way to get total memory. Here is how it now
gets memory information:
TOTALMEMORY: runs virsh info that gets the real physical memory
installed in the machine
FREEMEMORY: runs free command and gets the free column data without
buffers and cache
USEDMEMORY: runs top command and gets used memory from it (this counts
buffers and cache)
This is a big problem as those values do not match one with another (I
don't really know how I failed to see this before). Here is the
monitoring data from a host without VMs.
--8--
TOTALMEMORY=8193988
USEDMEMORY=7819952
FREEMEMORY=7911924
--8--
As you can see it makes no sense at all. Even the TOTALMEMORY that is
got from virsh info is very misleading for oned as the host linux
instance does not have access to all that memory (some is consumed by
the hypervisor itself) as seen calling a free command:
--8--
total used free sharedbuffers cached
Mem: 81939887819192 374796 0 64176
7473992
--8--
I am also copying this text as an issue to solve this problem
http://dev.opennebula.org/issues/388. It is masked to be solved for
2.0.1 but the change will be compatible with 1.4 as it seems the the
only changed needed is the IM problem.
I can not offer you an immediate solution but we'll
