Re: [one-users] Passwordless ssh between VM's?

Hello, Thank you both Poul and Olivier for your answers. Poul, regarding my environment: it is small-scale experimental environment (up to ~10 VM's), NOT a production one.  For experimental and test cases, should I go with the solution written by Olivier, or is it still more easier and convenie

Re: [one-users] Dynamic IP Leases and NIC hotplug on Running VM

That might break the cloud model. If you have to make such a massive change in your running vms you might as well create a new template from one running and add the nic to it and roll it into the current system. You can always hot plug with extra vms directly from the hosts. Shank On Thu, Mar 22,

[one-users] Dynamic IP Leases and NIC hotplug on Running VM

Hello I'd like to be able to Add IP addresses (Leases) to running VM (hot plugging new NIC). Is this something possible? From what I understand this is not possible (as of OpenNebula 3.3). A VM would have to be destroyed and a new template submitted. My thinking was something like adding a one.v

[one-users] Distributed File System with OpenNebula

Hi all, I recently installed OpenNebula in a test environment for evaluation purpose and got it working with a VMware ESXi5 hypervisor. Right now I have 3 machines: - the front end with OpenNebula installed - the hypervisor with ESXi - the storage, mounted both on the front end and on the hyperv

[one-users] VM life cycle - error handling

Hi, I do encounter (very rarely as it seems) problems where VMs are not properly deleted or shut off by onevm commands. I use ONE 3.0, hosts running Fedora15 and KVM and libvirt. 1) onevm shutdown fails: I can see in the VM log file that the shutdown operation timed out and the VM is still r

Re: [one-users] suspend vm on esxi 5

Hi, The .vmx file is created by libvirt. OpenNebula can be tailored to add the line in the file, but I think is better to identify the problem. 1) Are you using a .vmdk disk created in esx5, or are you importing from previous versions? 2) If you add the line, can you create snapshots? 3) If yo

[one-users] suspend vm on esxi 5

Hi All, I configured opennebula to use esxi 5 as hypervisor. The instantiate, shutdown, reboot commands work properly. I'm now testing the suspend function but I have such a problem: from sunstone I choose a RUNNING vm and suspend it, it goes in SAVE_SUSPEND state, then it goes in UNKNOWN one. f

[one-users] Running EC2 Instances in two different regions

Hello, my goal is to run two regions as vmhosts in opennebula. My first step was to create two different monitor and driver sections: IM_MAD = [ name = "im_ec2_us-east", executable = "one_im_ec2", arguments = "im_ec2/im_ec2_us-east.conf" ] IM_MAD = [ name

[one-users] is it possible to reduce cpu/ram of a host?

Hi, I'd like to know if it is possible to define a "security limit" for hosts to be sure for example that we keep at least 1 cpu and 2Gb RAM free on the host server ? Though VM template can define some requirements on host by the user, I'd like to define some "hard" limits. Thanks Olivier --

Re: [one-users] What happens with multiple front-ends?

Hi, We have the openebula daemons running on one VM, and Sunstone running on another VM. (These Vms are of course not controlled by opennebula.) There should be no problem at all to have multiple instances of the sunstone web-UI up and running simultaneously. Just make sure you do not run mu
