[one-users] Easy provisioning missing from newer versions of Opennebula?

2014-11-04 Thread Pentium100
Hi, I have tried Opennebula 4.2.0 and liked the easy provisioning wizard - a user could select a template and combine it with his persistent image to create a VM without the need to create a separate template. It seems that this function is missing from Opennebula 4.8.0, requiring eveyone to

[one-users] Local system datastores and free space monitoring

2014-09-22 Thread Pentium100
Hello, I am testing OpenNebula with local storage (local SSDs are faster than shared storage), however, I do not understand how (and if) OpenNebula monitors the available free space in each hypervisor. Let's say I add filesystem datastore with ssh TM. It looks to me like only the free space on

Hi, Let's say a user created a VM using a non persistent image (a template). Is there a way to now clone the image and make it persistent (remember - the user does not own the original non persistent image) without losing data. Alternatively, is there a way to allow a user to clone the image but

[one-users] Simplified VM creation?

2013-09-04 Thread Pentium100
Hello, While trying out OpenNebula, I noticed that the VM creation process is quite inconvenient if I want different VMs (as opposed to scaleout situation). 1. Create the image (upload a new one or copy some other image), set it as persistent (I don't want the VM to disappear if I shut it down).

[one-users] Local storage on the node (lvm, etc)

2013-07-19 Thread Pentium100
Hello, As far as I understand the documentation, it looks like all storage options for OpenNebula are shared - ceph, iSCSI, nfs, cLVM. However, configuring the storage locally on the node would allow for better performance (especially if using SSDs), even though the VM then would not be fault

Re: [one-users] DHCP and OpenNebula

2013-07-11 Thread Pentium100
From what I understand, OpenNebula encodes the IP in the MAC, for example, the VM with assigned IP 10.0.0.2 would get a MAC 02:00:0a:00:00:02. Just create an IP:MAC list for the DHCP server and it will work. host a10-0-0-1 { hardware ethernet 02:00:0a:00:00:01; fixed address 10.0.0.1; } host

Hello, I am trying out OpenNebula as a replacement for our current system of just using virt-manager to manage the VMs. We use the VMs as replacements of real server - which means that each VM is unique and should not be deleted (unless, of course, it is no longer needed). There are no multiple
