[one-users] Update on Release 4.6
Hi As you probably know, there is a bunch of new features already packed in the master branch of the git repository [1]. These new functionality includes the redesign of the VDC provision model and a brand-new federation system for OpenNebula instances (oned). We wanted to deliver this ASAP, so we decided to make a checkpoint release. So we are going to release all the features we have now (beta should be out by the end of the month) and continue working with the original plan for 4.6 after that. There may be room to slightly adjust the current roadmap. In summary: * OpenNebula 4.6 will include all the features already developed * OpenNebula 4.8 will include the rest of the features originally planned for 4.6. We expect to have short release cycle for 4.8 Cheers Ruben [1] https://github.com/OpenNebula/one -- -- Ruben S.

Thanks Stefan. Now, It make sense.

Ruben On Mon, Feb 17, 2014 at 11:36 AM, Stefan Kooman ste...@bit.nl wrote: Quoting Ruben S. Montero (rsmont...@opennebula.org): Hi Stefan The IPv6 design in OpenNebula is basically designed to work with the auto-configuration features of IPv6. An IPv6 capable host will always have link-local addresses for all their interfaces. AFAIK you cannot disable IPv6 stack per interface. In linux you can do so quite easily: echo 1 /proc/sys/net/ipv6/conf/$interface_name/disable_ipv6 So it really does not make sense to have one interface for IPv4 and other for IPv6, as the IPv4 will also have the link local addreses (plus the host multi-cast address). I agree with you that having seperate IPv4 and IPv6 interfaces (normally) doesn't make much sense. Quoting myself here: 3) two different interfaces, one for IPv4 and one for IPv6. I didn't make myself clear on that point. Just like you I would like to avoid having seperate IPv4 / IPv6 interfaces. But at present the only way to provision a (contextualized) vm with or without IPv6 is to give it an interface in a IPv4 only network or a IPv6 network. If you would like to combine IPv4 and IPv6 in one vnet (dual-stack) and ENFORCE_IPV4, a vm will always get an IPv6 address. There's currently no way to disable that. The thing I would like to propose is the defintion of a dual-stack network with the following attributes: ENABLE_IP, ENABLE_IP6, ENABLE_DUALSTACK, actually funtioning as switches. About the generation of the host-id (the 64 lower bits) can be generated: following the modified EUI-64, based on the IP, or by any other means (usually random generation is accepted as a more secure option). But I see this as part of the guest configuration and probably not for context (although you could generate this through a context variable or using the IPv4 address...) Yeah, this whole IPv4 / IPv6 enable/disable thing can also be handled through contextualization. We could change the behaviour based on some template attributes and fix networking at startup. So the ideal setup is to have a router in your virtual network advertising the IPv6 network prefix (e.g. radvd or zebra) and then let the ICMPv6 protocol autoconfigure the interface. The addresses shown in OpenNebula are supposed to match those obtained by the previous procedure (as long as the prefix advertised is the one configured in the vnet). The downside of having RA's in your network is that vm's that only need/want IPv4 (for whatever reason) have to be adjusted beforehand not to do anything with IPv6 autoconfiguration. On the other hand, if your using VRRPV6, because of network redundancy, routers are obliged to sent them (RA's) and also have to respond to RS requests (RFC 5798) [1]. Currently, the only way to add more IP addresses is to add more network interfaces to the VM. Probably a nice feature could be a NIC of type alias or virtual so you get the lease from the vnet, but not an additional nic. The context script can simple ip addr add the IP from the virtual NIC through context. Exactly, having a alias possibility would be nice. Escpecially if you would like to have all ip administration consistent in OpenNebula. You wouldb able to can query the template for IP info and match that to other ip administration (i.e. reverse dns entries) for consistency checks. This alias feature might overlap / complement [2]. Probably, I am not fully getting your proposal... Does it make more sense now? Gr.

That is, a disabled system DS would be ignored by the scheduler, but you can still deploy VMs manually there. I think this would support Daniel's use case. But how do you deploy a VM manually? I.e how do you by-pass the scheduler (except by creating a WILD vm)? You can use the onevm deploy command, or the sunstone button. To avoid the scheduler being quicker than you, pending VMs can be put on hold. Or use the onetemplate instantiate --hold option. At the moment the multi DS support is configured at template level. From a system perspective it would be nice to be able to control which datastore gets used. For example filter on user, group, vm template attributes, etc. At least we have a use case for this (seperate Qtree per datastore for IO billing). It proably makes the scheduler's life more complicated :(. So, basically adding ACL rules to grant deployment rights for each system DS, right? What do you think? Should I open a ticket for this?

Hi The script does not need to be present in the hosts.

Re: [one-users] Need some details on CPU/vCPU in Sunstone and capacity planning.
Hi, On Mon, Feb 17, 2014 at 4:29 PM, kiran ranjane kiran.ranj...@gmail.com wrote: Hi Everyone, I have few questions with regards to cpu and vcpu while creating templates in Sunstone : 1) What is the difference between cpu and vcpu according to opennebula architecture? CPU refers to the physical Host cpu cores, the one you see in the allocated cpu column. vCPU is simply the number of cpus that the VM guest will see, but it does not affect the physical resources assigned to the VM. 2) How do we calculate vCPU, For example if I have 1 processor with 8 core then how much vCPU can I allocate. They are not related. But the scheduler will not deploy more VMs when the sum of the running VM CPU reaches 8. 3) How can I manage cpu capacity (recommendation) in a better way so that I can utilize it in optimum way. 4) Any calculation on CPU or formula that we need to use before assigning it to Virtual machine, For example if I use 1 CPU in the virtual machine it uses 1 core of the processor? is this correct. 5) What is the use of vCPU, If I have allocated 1 CPU and 2 vCPU to the virtual machine thus that mean it will use 1 core of the physical and inside the VM it will show 2 cpu assigned to it? The purpose of vCPU is to allow cpu overcommitment. For example, for a host with 8 cores, you could create 4 VMs with cpu=2, vcpu=2 But if your VMs workload is not very cpu-intensive, you could decide to launch 16 VMs cpu=0.5, vcpu=2 To ensure that the VMs are not using more CPU than the amount assigned, you may need to configure your hypervisor. For example, in kvm you need to configure cgroups [1] Regards [1] http://docs.opennebula.org/stable/administration/virtualization/kvmg.html#working-with-cgroups-optional -- Carlos Martín, MSc Project Engineer OpenNebula - Flexible Enterprise Cloud Made Simple www.OpenNebula.org | cmar...@opennebula.org | @OpenNebulahttp://twitter.com/opennebula ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

Re: [one-users] EC2 / cloud bursting - multiple AWS credentials
Quoting Carlos Martín Sánchez (cmar...@opennebula.org): Hi Stefan, On Thu, Jan 30, 2014 at 7:52 AM, Stefan Kooman ste...@bit.nl wrote: Hi, I was reading through Amazon EC2 prerequisites [1] which implies that there can be only one set of AWS credentials per opennebula cloud. Is that correct? This might not be a problem for a private cloud operated by only one organisation / company. For a public cloud that want's to leave room for 3rd party cloud bursting it is a problem. Ideally every user / group should be able to provide his/her own credentials while instantiating/creating a new vm. What is the reason to use a config file for this instead of having this info in a template? Gr. Stefan [1]: http://docs.opennebula.org/4.4/advanced_administration/cloud_bursting/ec2g.html#prerequisites Actually you can define multiple ec2 accounts, see the Multi EC2 Site/Region/Account section of that guide [1]. You can create a hybrid host for each group, and then adjust the permissions so each one can only deploy VMs in the host with the right credentials. Ah, I see. Thanks for the pointer. We could come up with an ec2 driver that reads the credentials from the VM template, although I'm not sure how difficult it would be to make it work with the current code. Please open a feature request if the above multi account feature does not solve your use case. Generally I would like to avoid having stuff hard coded in config files, except for global settings / defaults. If you would like to give (power)users the possibility to use cloud bursting it would make sense that they are able to configure that by themselves. Then again, I might be thinking the wrong way around. Instead of giving the posiblity to use a public cloud from within OpenNebula, one might as well create a virtual machine with OpenNebula installed just for that. And federate with the cloud it is running on to manage local vm's ... I've just read about vDCs, Resource Providers and Groups. With that functionality in mind, a public cloud might be a Resource Provider by itself and therefore be partitioned by the Group Admin. Multiple public clouds (Resource Providers) might be created this way, each one with different properties and credentials. One thing that is breaking this logic is that someone else than the owner (consumer that rents resources) has to configure the Resource (enter the credentials / keys), which doesn't make sense. Just thinking out loud here. I might have to sleep over it for a day. Gr.

[one-users] OpenNebula and ceph: why rbd copy rather than rbd clone?
Hi all, Silly question. I've just thrown together an OpenNebula cluster for evaluation purposes and have it using a back-end Ceph cluster for storage. Image creation works, but one thing I observe is that the VMs sit in the PROLOG stage for a long time. During this process, I see an rbd process busily copying the image to a temporary rbd for the instance. The call specifically is a 'rbd copy' command. I see in the manual pages for rbd: clone [parent-snapname] [image-name] Will create a clone (copy-on-write child) of the parent snapshot. Object order will be identical to that of the parent image unless specified. Size will be the same as the parent snapshot. Surely this would be more efficient than creating copies of the images. Is there a reason why 'copy' was chosen rather than 'clone' in OpenNebula? -- Stuart Longland Systems Engineer _ ___ \ /|_) | T: +61 7 3535 9619 \/ | \ | 38b Douglas StreetF: +61 7 3535 9699 SYSTEMSMilton QLD 4064 http://www.vrt.com.au ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

Now I'd like to give it an update, i.e. it should be a WAN environment, not a LAN, due to the LAN environment is too limited. I will setup another LAN in another location, then connect the current LAN in the office to the other LAN through Internet, that's what I called WAN (of course this is the simplest form of WAN). It is much appreciated if any of you can help to provide information for this. Thanks kindly, Q.D.S.
