Re: [one-users] How to exit SHUTDOWN_POWEROFF?

[Ruben S. Montero]

Hi

This is probably because OpenNebula is waiting for a result of the shutdown
operation. The driver has not answered back, and the VM is stuck in that
state.

About the fix, I am afraid that 3.8.3 requires modifying the DB and set the
state manually. This has to be done in the XML document describing the VM.
Since OpenNebula 4.0, oned offers you a onevm recover API call to fix these
kind of issues.

Cheers

Ruben

Yes it is configured by default. You have to enable it in the hypervisors,
though

Note that you have to do onehost sync to propagate the changes (or copy
manually the new probes). And then wait for the hosts to be monitored. This
approach should work without modifying the scheduler.

Re: [one-users] Network addressing and IP recognition in ONE

[Andreas Calvo Gómez]

Jaime,

Thanks, I’ll try to have some script that reads from one end and feeds the
other end.

 

However, do you foresee useful to have some kind of daemon inside the VM
that will update the IP address shown in ONE?

For instance, a VM is configured with a context that has the IP and port of
a REST service on ONE.

Once the ONE daemon inside the VM has started and it gets a valid IP
address, it pushes that information to ONE, so the IP address shown in the
WEBUI is valid.

I assume there will be some other dependencies – VMID, for instance – but it
could be a nice feature to deploy VMs in a mixing environment, or to have a
centralized network server.

 

It may not work with all network drivers, as it stills requires to have a
virtual network assigned with VLAN tagging – not having a virtual network or
some tagging at layer 2 would mean defining manually the MAC-IP pairs.

 

Thanks!

Re: [one-users] Network addressing and IP recognition in ONE

Dmtri,
It helps but still keeps the same behaviour: you have to define beforehand
the relation between MACs and IPs – either in ONE or in your DHCP server.

I don't know if this helps - when you create a VM you can request specific

Check if /sys/fs/cgroup/cpu/libvirt/qemu/ exists and it's contents, if

I didn't touch the scheduler, just patched the reporting script.
On my system it exists in ~oneadmin/remotes/im/kvm.d/kvm.rb and is
copied by ON (idr when exactly - restart?)  to /var/tmp/one/im/kvm.d/ on
every host in cluster.
I just added above lines near the end of script - before printing,
copied it manually and about minute later changes were visible in chart.

Use firefox's developer console to see what the problem is. It could be:
- web socket not available outside (use proxy that supports websockets
or make helper app listen on outside interface)
- sunstone running in https connection and trying to load non-secure web
socket (change wss = only in config)
- self signed certificate (add CA to browser or paste link from console
in browser (with port like 29876) and accept certificate also there)
or a combination.

You need to forward web sockets or reconfigure (I think I've seen such
option somewhere) noVNC to emulate WebSockets in http requests or just
allow websocketproxy.py to listen on outside interface. I've chosen the
last option.

Re: [one-users] @connecting vlan to host bridge

[Jaime Melis]

Hi Anagha,

if you're not familiarized with openvswitch I recommend you use linux vlan
tagging:
http://opennebula.org/documentation:rel4.2:hm-vlan

If you start a VM with two interfaces, each one in a differente vnet, then
you will have connectivity between the two networks. You will probably need
to define routes properly though.

Another thing that is worth mentioning is that in OpenNebula we don't
recommend the use of the libvirt network.

cheers,
Jaime

Hi,

I'm wondering what are the minimum (and maximum supported?) version
requirements for ruby packages on oned/sunstone. I would like to install
(ubuntu) packages instead of  doing a "gem install". It would make
package mangement easier for me. Currently I've installed the following
gems on a sunstone/oned/host test setup:

# gem list

*** LOCAL GEMS ***

amazon-ec2 (0.9.17)
curb (0.8.4)
daemons (1.1.9)
eventmachine (1.0.3)
json (1.8.0)
mysql (2.9.1)
net-ldap (0.3.1)
nokogiri (1.5.9)
rack (1.5.2)
rack-protection (1.5.0)
sequel (4.1.1, 3.47.0)
sinatra (1.4.3, 1.4.2)
sqlite3 (1.3.7)
thin (1.5.1)
tilt (1.4.1)
uuidtools (2.1.4)
xml-simple (1.1.2)

Thanks,

Stefan

[one-users] vnc via proxy web server

[Wojciech Giel]

Hello,
I'm trying to configure opennebula 4.2 sunstone with lighttpd as a proxy 
on the same server on Centos 6.4. web proxy works fine unfortunately vnc 
doesn't.


I have firewalls down on hypervisors and management server, qemu is 
configured with vnc. I can connect directly to guest on hypervisors with 
virt-manager or vncviewer and vnc is working. without proxy vnc is 
working as well but with web proxy it doesn't.


What should I do to get it working?
thanks
Wojciech

Re: [one-users] Some questions about overcommitment in OpenNebula 4.2 using KVM

[Gerry O'Brien]

Hi,

Do you know if the CPU parameter has any effect on the amount of 
real cpu used, e.g. if I set the CPU parameter to 0.1 will this limit 
the actual cpu usage?


Also, can the monitor driver be  configured to report multiples of 
memory and allow memory overcommitment in the same way?

I just configure the monitor driver to report 2x the cpu than it normally

for a 16 core cpu, I configure the monitor to report 3200 or some other
multiplier. I find scheduling with cgroups a bit hairy, I do use cpusets to
jail vms to specific numa nodes and avoid cross memory domain traffic but
that's about it.

 Am I correct in believing that by default cgroups are not enabled and
that the only use of the CPU parameter is to guide the scheduler? If
cgroups are not enabled and the CPU paramter is set very low, say 0.1, for
a VM then can the cpu share actually used by the VM can be much larger than
0.1?

 What is the correct interpretation of the "used CPU" value on the
Sunstone Virtual Machines view?

 Can balloon drivers be used with KVM in OpenNebula? If so, is there
any way around the fact that the MEMORY parameter seems to stop the
allocation of VMs to a host once the total sum of all MEMORY parameters
exceeds the physical memory available on the host?

 Is there any good reason why the scheduler only uses 90% of available
memory by default?

 I've tried searching the documentation and threads but cannot find any
answers to these questions so any help would be much appreciated.

 Regards,
 Gerry

Sorry for the noises, blocking addons prevent the download by blocking
some amazone S3 url ;-)

novnc listens on port 29876, so you have to open this port in the machine
where novnc (sunstone) is running

Thanks a lot, I really liked it, it's a very interesting presentation.

Now I have another problem, I would like to share it, with the others.

I will give the link in my slides but during our seminary we will setup a 
piratebox:

- because there is a presentation about it

- it permit to share our slides directly and differently

We would like to put OpenNebulaConf 2013 on it, to let people retreive
them.

All the slides are on slideshare and I can't download them[1], I created
an account, and click the “save” button:

- it's cumbersome: validating each “save” with an email

- it does not permit to download them, it just add a bookmark in my
  profile

Is it possible to download PDF of the slides to share them during our
seminary?

Regards.

Footnotes: 
[1]  The youtube videos are OK, thanks to VideoDownloadHelper ;-)

[one-users] @noVNc problem

[anagha b]

Hi

I am using opennbula-3.8.3 with kvm on ubuntu-12.04 lts

My vm is in running state but vnc not showing vm on host .
vnc icon is active but when i click on it error disconncet timeout appears.

Is it due to iptables ?

I allowed traffic Input on port ssh and tcp port .

for novnc what iptable rules to be defined?

Thanks .
