Hello, Even if NFS with default configuration is not the most performant shared filesystem we thought it was the most common shared filesystem people could use for virtualization. Maybe you can make it faster adding some parameters when mounting the shared filesystem. "async" will make your VM's r

Hi Jaime, thanks for the reply. /images is not a path it is the name of the VG, first I tried /dev/images and it did not work, when I change to /images it works. But it can not delete the snapshots afterwards. Cheers Italo On 2 September 2010 15:59, Jaime Melis wrote: > Hi Italo, > > it looks

Hi Tino, I think I am getting a little farther in that I was trying to use the onevm create instead of registering (which worked but not sure it helps). However it fails to create the vm and I find this message in the vmm_vmware.log: [02.09.2010 11:57:44] Failed deploying VM 1 into 12core.x

Hi Italo, it looks like $VG_NAME contains "/images", but it shouldn't be a path, it should be the name of the volume group that LVM uses to create LVs. Try changing that to "images", by editing tm_lvmrc. cheers, Jaime On Wed, Sep 1, 2010 at 5:30 PM, Italo Madalozo wrote: > Hi, > I have been tr

Hi Jonathan, The way to use the image catalog is to upload individual images, each of them requiring an image template [1]. One registered, a VM can use an image by just referencing the image's name (same as the VirtualNetwork from your template, using just the name "VMWareNET"). Regards, -Tino

I've found that NFS is unacceptably slow too. With both the front end and the nodes mounting NFS, copies have to go through the front end, then back out again, which is a bit wasteful. We use a NetApp storage system, which can do flexclones. We can't take advantage of that with OpenNebula becaus
