Re: [one-users] Express Installation Script.
Thanks Daniel, this worked for me , i think i need to dig further into the syntax of templates. I am able to create new vms based on the raw image i created using virt-manager which is registerd as OS image. Can you share with me your opennebula deployment scenario and how you are using it. Can i migrate the current setup to mysql db after installing from express script ? Also I am trying to understand how to interface with opennebula setup using ruby oca api to build some basic web frontend to manage the opennebula setup. A simple webpage which displays statistics like If you have any information for the same Will keep posting my experiences and queries. @Daniel: Let me know if i can contact you directly for some knowledge sharing.

[one-users] VMs stuck in PEND state
Hello, This is the first time that i'm using open nebula, so i tried to do it with express script which ran fine. I'm using CentOS 5.5 with Xen. The first thing that i'm trying to do is getting the following vm running: NAME = ttylinux CPU= 0.1 MEMORY = 64 DISK = [ source = "/var/lib/one/images/ttylinux.img", target = "hda", readonly = "no" ] NIC= [ NETWORK = "Small network" ] FEATURES=[ acpi="no" ] So i used: onevm create ttylinux.one The issue is that it keeps stuck in PEND state: onevm list ID USER NAME STAT CPU MEMHOSTNAMETIME 3 oneadmin ttylinux pend 0 0K 00 00:20:03 At oned log the following messages keeps repeating: Tue Nov 9 20:29:48 2010 [ReM][D]: VirtualMachinePoolInfo method invoked Tue Nov 9 20:29:59 2010 [ReM][D]: VirtualMachinePoolInfo method invoked Tue Nov 9 20:30:18 2010 [ReM][D]: HostPoolInfo method invoked Tue Nov 9 20:30:18 2010 [ReM][D]: VirtualMachinePoolInfo method invoked And at sched.log, i see this: Tue Nov 9 20:31:18 2010 [HOST][D]: Discovered Hosts (enabled): Tue Nov 9 20:31:18 2010 [VM][D]: Pending virtual machines : 3 Tue Nov 9 20:31:18 2010 [RANK][W]: No rank defined for VM Tue Nov 9 20:31:18 2010 [SCHED][I]: Select hosts PRI HID --- Virtual Machine: 3 Any ideas of what might be happening? I saw other threads here at the list with similar problems, but their solution didn't applied to my case.

[one-users] opennebula 2.0.1 under Debian Lenny (5.0.6)
The opennebula 2.0 debian package for Lenny (5.0.6) has a dependency on libmysqlclient16, althought the default Lenny repository only has libmysqlclient15. I'm posting here, knowing there are another thread for the same issue, since the second November : "OpenNebula Express 2.0 on Debian_5.0.6 problem" By my meaning should opennebula not never depend on a backport package. Would it be a problem to change the dependency in the package and use libmysqlclient15 instead of libmysqlclient16? Has it been tested?
