Hi,
I am a newbie OpenNebula user and I have a problem…
I just finished installing the opennebula system with only one kvm virtualization host (centos 6.9 final) and I tried to run multi istances of ttylinux-kvm images but only the first start regularly the others remain in Pending status. Then I tried to run ttylinux-kvm and Ubuntu 16.04 - LXD together but again only the first runs… the second stay pending.
where is the error?
thank you all
@fbordini, you need to install LXDoNe addon in order to manage LXD containers on OpenNebula. Ubuntu 16.04 - LXD is an LXD container image.
OpenNebula doesn’t support multi instances nodes by default. As a workaround, you can follow the guides to prepare the same node to run KVM virtual machines and LXD containers and add it to OpenNebula twice (as a KVM node and as an LXD node). This way you can deploy KVM VMs and LXD containers on the same node 
thanks, for information but with more instances of ttylinux only the first start normanly, the others stay panding. is it the same problem?
Hi!
Can you put here the sched.log file (/var/log/one/sched.log)?
Regards!

sorry, but new users can not upload files…
Can I insert log in the answer?
Hi,
A link to pastebin or similar service should be ok too.

Hi,
this is the link with the last output log…
https://pastebin.com/GisjCXcZ
I don’t understand ‘there is no suitable host’ I have made two hosts but only can run KVM virtual machines.
Both instances must runs in same hosts…
I’ve never seen that in the logs
Have you tried to instantiate it manually? There’s no much info on the sched.log more than the scheduler couldn’t find a host that matches the criteria to deploy VMs 
I have not tried manually, but I have installed a new host node and I have instanced a second VM. It works … but I must create N identical VMs in a same node and now it does not work. The next week I will try manually … I keep you updated.
Bye
Hi,
I’ll try to execute manually three VMs and the result is …
onetemplate instantiate 1
VM ID: 51
onetemplate instantiate 1
VM ID: 52
onetemplate instantiate 1
VM ID: 53
onevm list
ID USER GROUP NAME STAT UCPU UMEM HOST TIME

52 oneadmin oneadmin ttylinux - kvm- unkn 0 0K HostMaster 0d 00h01
53 oneadmin oneadmin ttylinux - kvm- pend 0 0K 0d 00h00
the last instances does not start…
Hi!
Can you put the output of the onehost list command?
The scheduler can not find any active Host.
Regards!

… but the instances work fine…
I have create a my VM image … but on the same host the second one remains pending and the host status return the error above…I do not know what to do …
Have you followed the LXDoNe setup guide step by step?
Sorry but I do not understand … why do I have to install LXDoNe feature? I followed the main setup guide.
LXDoNe is an addon, its not provided by default by OpenNEbula. If you want OpenNebula to manage LXD containers then yo have to install the addon.
But also a personal Image made by iso needs of the the lxd addon?
