[one-users] KVM Qemu does not mount DATABLOCK.

Hi all, I have created a CentOS which is sized 2GB. I would like to add a DATABLOCK to it. However, the DATABLOCK cannot be found with fdisk -l (in the VM). It was able to mount the swap, but no the DATABLOCK. Here is the config file that I have. Via dumpxml in virsh: domain type='kvm' id='3'

[one-users] VM placement?

Hi I'm Adrian, a PhD student from France. Could you tell me if OpenNebula supports installation of one single cloud across multiple clusters (similar to EC2's availability zones/regions)? If yes, then is it possible to control VM placement from a user's point of view? (similar to EC2's

Re: [one-users] VM placement?

there are clusters in opennebula, and you can place hosts in a cluster. In instance template, you can add a requirement on cluster Olivier Le 3/4/11 11:02 AM, Adrian Muresan a écrit : Hi I'm Adrian, a PhD student from France. Could you tell me if OpenNebula supports installation of one

Re: [one-users] KVM Qemu does not mount DATABLOCK.

Hi, This seems more a KVM/libvirt issue than an OpenNebula one as the three devices are listed in the deployment file. There has been some problems reported when mixing ide and virtio disks, that may be cause of the problem. You may try to put the three disks under virtio to check if that's the

Re: [one-users] KVM Qemu does not mount DATABLOCK.

Hi Ruben, Very appreciate for your reply. Unfortunately, even I have put all three disk to VIRTIO. It still not working. If I use ide, it seems that it is not able to have more than one IDE device. And SCSI was not supported by CentOS 5.5's kernel. Any idea to get around this? Thank You !

Re: [one-users] KVM Qemu does not mount DATABLOCK.

I've made something like this work, but I couldn't make the datablock as virtio. If you call for a virtio datablock by default it comes up as /dev/vde, for which many kernels don't have the drivers. So on mine, I declared OS image to be virtio / dev/vda, swap to be virtio /dev/vdb datablock

Re: [one-users] What's available about the LVM backend ?

Hi Gian, You're right, if you use a Cluster LVM [1] then you will be able to use migration with an empty tm_mv.sh (as you point out, same idea as the tm_mv.sh in the TM_NFS drivers). [1] http://www.centos.org/docs/5/html/Cluster_Logical_Volume_Manager/LVM_Cluster_Overview.html Cheers, Jaime On

Steven, It works, Great Thanks. I used virtio to all device. /dev/vda as OS image /dev/vdb as swap /dev/vdc as my Datablock. As you have mentioned, it might be some kind of kernel issue which work with vde driver. Very appreciate for you help. Besides, is it possible to make the disk

[one-users] can't create VM with shared vm dir

Hi, I have configured OpenNebula to use shared NFS for image repo and VM_DIR, e.g. /groups/one-vm-dir and /groups/one-images-dir are exported from a separate NFS server, both head-node and cluster-nodes have mounted these shares. Following is OpenNebula config: {{{ DB=BACKEND=sqlite

[one-users] exporting install dir to cluster nodes

Hi, The installation planning guide (http://www.opennebula.org/documentation:rel2.2:plan) mentions about exporting OpenNebula install location (ONE_LOCATION) to cluster nodes. I am trying to understand how this install dir is used by cluster nodes. Any elaboration would be really helpful.

[one-users] more universal name for poll_xen_kvm.rb

Hi! My first question is if that list is a proper one to ask questions related to ONE development? The second question (rather proposal) is to assign more universal names to the scripts. For example the script src/vmm_mad/remotes/poll_xen_kvm.rb could be named as e.g. poll_vmm.rb or
