Re: [one-users] VM stay in pending state

Hi Emmanuel, It looks like your host is not properly monitored, the memory and CPU are both 0. Could you check in /srv/one/cloud/var/oned.log if is there any monitoring error? The most common monitoring problem is that the passwordless ssh for oneadmin is not properly configured, or it is but

Re: [one-users] Error in 'onehost delete'

Hi Luis, The negative running VMs is a bug [1] that we thought was solved. What version are you running? To force the host deletion, just edit the onehost script and change if host['HOST_SHARE/RUNNING_VMS'].to_i != 0 puts Host still has associated VMs, aborting delete.

Re: [one-users] customizing tm_*.sh scripts for OpenVZ hypervisor [was $SCRIPTS_REMOTE_DIR in tm_*.sh scripts]

Hi, It looks like you could take adavantage of hooks [1]. This way you can perform preparative operations on create, running, etc., maybe storing some configurations files in $VAR_LOCATION/vm-id/ to be used later by your drivers. I'm sorry I can't dedicate enough time to write a more elaborated

Re: [one-users] opennebula on virtual box

Hi Ami, Depending on what you are trying achieve, you may find easier to just use the dummy drivers. Uncomment the three of them (im_, vmm_, tm_) in /etc/one/oned.conf. This way you can fake Host monitoring, and deploy and manage VMs. Regards. -- Carlos Martín, MSc Project Major Contributor

Re: [one-users] Pending state issues

Hi Madhurranjan, Regarding your first question, you can't modify an existing VM. You'll have to modify the source template, and then shutdown the current VM and create a new one. About the second one, your proposal seems reasonable. I'd say that the optimal values depend basically on your

Re: [one-users] Does OpenNebula work or replace VMware vCenter?

Hi Florian and all, thanks you for your comments. Although Tino is the main VMware driver developer and he will be able to provide more low-level details, let me say some words to clarify how OpenNebula compares with VMware products. OpenNebula 2.2 can be used on top of VMware ESX and vCenter. -

Re: [one-users] creating VMs

Hi, You don't have to create an OpenNebula-specific VM format, you can use your existing VM images or follow any tutorial for your chosen hypervisor. After you manage to create and deploy a VM for your hypervisor, you have to contextualize it in order to make the OpenNebula network management

Re: [one-users] Long Running Servers

Hi Richard, The template you propose looks fine, but let me make a couple of comments. Instead of 'source' and 'save' for DISC, you should use the Image repository, and take advantage of the persistent flag [1] to make sure the contents are saved. This way you can forget about the 'save',
