Re: [one-users] iscsi target as a guest disk

Hi,
This is how I create a connection to the server

Check that you are using the

to make user that you are using the correct client. Also send the
stacktrace if you are still facing problems.

Re: [one-users] xmlrpc client
You appear to use the hashed password and not the password itself. Use the
real password to construct the session string.

Re: [one-users] Error: Cannot find kernel /boot/vmlinuz.. + Open Suse cluster
Hi, The kernel and the initrd path should be present on the cluster node where Xen is installed. The error specifies that Opennebula cannot find the kernel. Check if the file is present at these paths and their permissions. Prakhar.

Re: [one-users] Can't restart or resume VM when VM is in save status. And MEMORY = 0 when VM is running .
Hi, If by saving you intend to 'resume' that VM at a later point in time,your steps are correct. Regards, Prakhar 2011/4/8 Khoa Nguyen vankhoa...@gmail.com Hi Prakhar Srivastava Thank you for your reply. If i want to save a VM . 1. onevm stop id 2. Wait until changing from saving to stopping state. 3. onevm resume id. Is that right? 2011/4/8 Prakhar Srivastava prakhar@gmail.com Hi Khoa As already stated by Carlos, the save state is an intermediate state in which the running VM image is saved to the disk. This might take a little time and in the the mean time, the VM state is save (means it is saving the image so that it can be resumed from the state at which it was stopped). You cannot perform resume at save (saving...) state. It will always give an error. Once the VMs image is saved completely, the state changes to stop (means the VM is stopped).

Re: [one-users] Setting up private networks for VM
Hi Jaime, I did as you said. I specified the same bridge eth0 for both the public and the private network. I created two VMs with both public and private interfaces. I could ping private IPs from within the virtual machines. However I was surprised to see that if I create one VM with both public and private interfaces and one VM with just the private interface, I am not able to ping the private only VM from the both-public-and-private VM which was something I wished to do. In a general case, I wish to have just a single both-public-and-private VM(call it master VM) for a user and other VMs should have just the private interface so that it can be accessed from the master VM. Is this behavior normal or I am missing something ??

Re: [one-users] Can't restart or resume VM when VM is in save status. And MEMORY = 0 when VM is running .
Hi Khoa As already stated by Carlos, the save state is an intermediate state in which the running VM image is saved to the disk. This might take a little time and in the the mean time, the VM state is save (means it is saving the image so that it can be resumed from the state at which it was stopped). You cannot perform resume at save (saving...) state. It will always give an error. Once the VMs image is saved completely, the state changes to stop (means the VM is stopped). You can only resume a VM from a stopped or suspended state. So if you are not getting to 'stop' state, please check your vm.log file for any error. You can find the log file in /var/log/VMID/vm.log.
