To get a better answer, add information regarding your many issues, describe your cloud (e.g. how many nodes, their characteristics, the network setup), and characterize the current load on your cloud (e.g. number of instances, what resources are in use – see Horizon’s front page).

 

>From the information you provide, I can say that the launch fails because no compute host was found that could run the instance. Possible reasons (the list is not exhaustive):

*	No compute host has enough free CPU, RAM or disk storage resources
*	The instance’s CPU architecture is not compatible with the compute hosts’ hypervisors and/or CPUs
*	The image from which the instance is launched requests conditions that are not met by compute hosts
*	You set instance launch options whose conditions are not met by compute hosts

Subject: openstack/devstack issue

 

Hi, 

I was building a system i.e. an orchestrator that includes resources like an ubuntu virtual machine, firecracker micro virtual machine, unikraft unikernel and a storage. It seems that openstack/devstack is capable of orchestration of  such a heterogeneous system and could be customized according to the specific needs. I, however, am experiencing a lot of issues when including the resources e.g. when i try to create an ubuntu image and launch it, it results in errors that are quite complex to resolve and so i intend to reach out to the experts so as to resolve these issues at hand. 

 

 

Regards
