[one-users] OpenNebula 2.2 Cluster Error

[Clément Berthelot]

Hey guys,

Just sorted out my SSH problem (I forgot to add the password when I created oneadmin on the node machine). I can finally ssh the node from the frontend and it does not ask for a password. However, when I add a host on the frontend (onehost create 10.1.1.1 im_xen vmm_xen tm_ssh), its status is set to on for a few seconds and then it goes to ERROR. I checked the oned.log file and it shows this:

I did configure the oned.conf file so it supports xen (4.0):

IM_MAD = [
name =  "im_xen",
executable = "one_vmm_sh",
arguments = "xen" ]

VM_MAD = [
name =  "vmm_xen",
executable = "one_im_ssh",
arguments = "xen",
default = "vmm_sh/vmm_sh_xen.conf",
type = "xen" ]

TM_MAD = [
name =  "tm_ssh",
executable = "one_tm",
arguments = "tm_ssh/tm_ssh.conf" ]

Any idea where the problem is coming from ? For the moment I don't have any VM running on the node, I want to make sure opennebula detects it before making any. 

Cheers,

Clement
