Re: [one-users] VM Templates
Can you check libvirt logs of host. Generally the below message comes when there is address already in use(vnc port). error: monitor socket did not show up.: Connection refused If change the vncport and try.

[one-users] Match-making scheduler question
Hi, I'm writing a survey on Clouds for research purposes. I have some questions related to the match-making scheduler that OpenNebula uses: 1. it's not clear for me if the placement policies can be configured per VM type or per VM instance, could you clarify this? 2. are the placement policies configurable per cloud client or for the whole cloud platform? 3. is it possible to configure the policies in such a way as to distribute a client's VMs across the physical hosts in such a way as to reduce the probability of platform failure as a result of hardware failure? Is this do-able without modifying the source code of OpenNebula?

Re: [one-users] Match-making scheduler question

I have some questions related to the match-making scheduler that OpenNebula uses: 1. it's not clear for me if the placement policies can be configured per VM type or per VM instance, could you clarify this? The Requirements and rank expressions are given in the VM description file (template), so they can be configured per VM instance. However when using a cloud interface, the user can not specify these attributes and so are defined by the cloud administrator per VM type. 2. are the placement policies configurable per cloud client or for the whole cloud platform? Both scenarios can be implemented. 3. is it possible to configure the policies in such a way as to distribute a client's VMs across the physical hosts in such a way as to reduce the probability of platform failure as a result of hardware failure?

[one-users] Virtual Machine Static IP Address
Hy, Is there any method of assigning a fixed/static IP to a virtual machine? I have tried anything, even creating a virtual network with only one IP as lease like below and assign this network to the virtual machine in the vm template. NAME = VM2_net TYPE = FIXED BRIDGE = virbr0 LEASES = [IP=192.168.122.23] Nomather what i try, the virtual machine will always get a random IP located in the subnet of the virbr0 bridge. Although using onevm show, the IP i have requested is reported as assigned, inside the virtual machine things are different. Can there be issues regarding the host/guest OS? I am running CentOS as host and currently experimenting with Ubuntu JeOs and Desktop editions as guest systems.The network configuration inside the hosts states that the IP is assigned by DHCP. P.S. And just of curiosity(i am new to bridging/networking) how difficult it is to perform some bridging or connection in order to be able to ping the virtual machine from any opennebula node or client, not just from the current host of the virtual machine?

Re: [one-users] VM Templates
Hi Luca, DRIVER attribute is not included in the last release of OpenNebula 2.0 It is in the one-2.0 branch. You can download it form the fir repo, the fix will be distributed in the next maintenance release (at the end of this month) Cheers Ruben On Thu, Nov 18, 2010 at 6:05 PM, Luca Lorenzini lorenzini.l...@gmail.comwrote: @Upendra Moturi: the setting of the vnc port is based on the VMID and it's unique. Also i havent any other applications or vms using vnc. I think i found the problem: I'm using qcow2 image format to save disk space and I noticed that the DRIVER attribute is discarded in deployment file creation and i'm not able to use qcow2 format for my images. Without this i cant use images created with backing_file either. I put the driver name='qemu' type='qcow2' / by hand in the deployment file and deploy it manually and the image boot. To do this i left my not-booting-vm running so the link to the image wasnt deleted, i change few things in the deployment.0 file (the name, the vnc port, and i've add the driver tag) and used virsh create deployment.0 command. The vm works fine and use the image with backing_file option. I hope this feature will be fixed asap!

Thanks to all for the answers. And i have a question for opennebula developement. Why in /one/tm_commands/ssh/tm_context.sh, the temporary directory is TMP_DIR=$ONE_LOCATION/var/$DST_HASH ?
