[one-users] external DHCP
Hello, We're building a VM farm with OpenNebula. However, I'm a little bit confused about how to handle networking. Our scenario is based on VLAN tagging and external DHCP server for every VLAN. Our goal is to use that external DHCP server to provide IPs for all VMs. When creating a Virtual Network, a mandatory parameter is the range or fixed address (otherwise it fails complaining it cannot allocate the VM Network). We've tried Open vSwitch (without luck -- fails to create the vm directory) and 802.1Q (needs an explicit range/fixed address to instantiate a template). Is it possible to use a external DHCP server? Is there any issue using any VLAN tagging service (802.1Q or Open vSwitch)?

[one-users] write changes using save as and qcow2
Hi all, What is the procedure to save a running VM as an image if it's running with QCOW2? As per the documentation, I've used shutdown after issuing save as, but the image gets in a LOCKED stated and do not progress. If the VM gets deleted, the image changes to READY but I think it's just a link to the old image used by the VM. Trying to start a new template using this new image throws an error. Tried with SHUTDOWN and STOP without luck. I guess I'm missing something, does anyone how to do it? Thanks in advance ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

Re: [one-users] Using shared fs and ssh TM
The shared storage is mounted in the same place in all the nodes. The directory structured is as follows: /var/lib/one/datastores (shared storage) -- 0 - link to /one/datastores/0 -- 1 -- 100 /one/datastores/ (local storage) -- 0 -- 1 - link to /var/lib/one/datastores/1 -- 100 - link to /var/lib/one/datastores/100 When a virtual machine is stopped, its delta is stored in /one/datastores/0/$VMID. When another node tries to resume the virtual machine, expects to have in the same place the delta (and some other files, like the checkpoint), but, as it is not in its local disk, it fails. Same thing happen when a virtual machine is migrated. I think the TM should be tweaked to be part qcow and part SSH.

Re: [one-users] Using shared fs and ssh TM
No, System datastore (where all QCOW2 delta are stored) is not shared, it relays on the node local filesystem. However, datastore 1 (where all images are stored) it is stored and shared on all nodes under the same path. To use the same directory logic, the paths have been linked. In this case: /var/lib/one is shared on all nodes /var/lib/one/datastores/0 is linked to /one/datastores/0, which is local /one/datastores/1 is linked to /var/lib/one/datastores/1 (which is shared) If I'm not wrong, the system datastores holds the incremental changes, whereas the other datastores hold images.

Re: [one-users] Using shared fs and ssh TM
No, this directory is linked to be only at the node's local filesystem -- as it is the one that holds QCOW2 deltas. Only the image datastore (/var/lib/one//datastores/1/) is shared. Main problem is R/W access to the shared filesystem, and that's why we tried to hold deltas at node's local filesystem -- by linking the system datastore to a local path on the node. So far so good, except it cannot do any migration nor save.

Re: [one-users] Sharing images between clusters
Carlos, Thanks for your answer. From what I understand, the Image Datastore must be accesible from the hosts selected (all or just a cluster). However, the system datastore must be shared between the cluster (store transient data). On my scenario, clusters do not share the same Image Datastore nor can access the same resources. System datastore was planned to be local (on the DMZ node's filesystem), and the image to be transferred over the network. So, when moving an image from one cluster to the other (or starting a VM in the DMZ cluster), can Opennebula's manager copy over the network an image that's stored using iSCSI (image datastore) to the DMZ's node filesystem (system datastore), giving the premise that the DMZ node cannot access iSCSI?

Hi,
That problem has been fixed in newer versions, upgrading is recommended.
You can fixed it by changing the following line:
https://github.com/OpenNebula/one/blob/release-4.2/src/sunstone/public/js/plugins/vms-tab.js#L3217
to
if (graphics graphics.TYPE graphics.TYPE.toLowerCase() == vnc

Hello,
Since this morning, our Opennebula 4.2 Sunstone portal shows no virtual

The rest of the information (hosts, networks, templates, images, users,

Looking at the logs doesn't give much hint, all requests are 2xx and no
error are handled either in sunstone.error or oned.error.
Issuing a onevm list as the oneadmin users shows the current list of
VMs running.
Any hint or file to look?

[one-users] Granted operations with ACLs
Hi, Following the example in the documentation for managing ACLs ( http://opennebula.org/documentation:rel3.8:manage_acl), how should be implemented if we have two groups of users which should be able to execute VMs, but one set of users (say, administrators), which should be able to create any resource and assign it to the corresponding group? Imagine a scenario where we have to groups, A and B; and a group of admins, Admin. Groups A and B should only be able to execute resources on their own group. Admin group should be able to create resources and assign them to a specific group. The only thing that is missing is the chgrp/chown commands under the sunstone webui, which is the reference tool to use. -- Andreas Calvo Gómez Systems Engineer Scytl Secure Electronic Voting Plaça Gal·la Placidia, 1-3, 1st floor · 08006 Barcelona Phone: + 34 934 230 324 Fax: + 34 933 251 028 http://www.scytl.com NOTICE: The information in this e-mail and in any of its attachments is confidential and intended solely for the attention and use of the named addressee(s).

Re: [one-users] help: with 8021q driver, network configuration won't work, after host reboot (???)
Opennebula recreates all necessary interfaces on demand.
It means that, once a virtual network uses .1Q, it will create the
bridge to route the traffig and map the VLAN on the physical interface.
Dependenig on your distribution, you may need to specify the path of the
bridge control binary (brctl).
On Red Hat derivative, it is located on /usr/sbin/brctl; whereas the
default location should be /sbin/brctl.
You can either tweak the network scripts to look for the correct path or
make a link.

Re: [one-users] help: with 8021q driver, network configuration won't work, after host reboot (???)
In such case you must know beforehand all VLANs, set them up and create the necessary bridges. Be careful to put the same configuration on OpenNebula and in the host, as it may lead to having a VMs tied to a different bridge.

[one-users] opennebula upgrade to 3.8.3 minor errors
We have performed a update of both the OS (CentOS 6.2 to 6.3) and OpenNebula (3.8.1 to 3.8.3), and are facing some errors that weren't in the older release: - Logs can't be viewed from the webUI: selecting the VM Log tab shows an error message Log for VM XXX not available. - One node can't establish network connections: started VMs on one specific node don't have network connectivity, while they get the IP address by context. All other nodes work fine. - Sunstone/ONE seems to be stucked from time to time when performing large operations: as the old version (3.8.1), Sunstone becomes unresponsive and it is necessary to shut down all applications (one, sunstone, occi) and start them again. It usually happens when performing an operation with a large set of VMs. For all errors, no log in /var/log/one give any hint.

[one-users] Network addressing and IP recognition in ONE
Hello all, Network addressing under ONE (with any of the drivers) seems target to isolated/dedicated networks, where one can assume all IP address can be guessed by the MAC. However, when mixing a working network segment with ONE, you have to sacrifice something to get it working. Currently, there are 3 options: - Virtual Router - Virtual Network with fixed range - Virtual Network without range None of the mentioned options will fit with an external network services server (DHCP, DNS) and let ONE know the right address of a VM. Would it be possible to, given a VM and all context parameters, push the IP information into ONE? In a more practical approach: during the startup of the OS, get a valid IP address, and during the context script, push that information to ONE. Seems a little bit more dynamic, since nothing is hardcoded either in Virtual Networks or in the network service (DHCP), plus it gives the ability to control from outside and integrated with other services.

Re: [one-users] Network addressing and IP recognition in ONE
Jaime, Thanks, Ill 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.
