Cannot dispatch VM to any Host. Possible reasons: Not enough capacity in Host or System DS, dispatch limit reached, or limit of free leases reached

Hi everyone, I’m new to Opennebula. I decided to feel the system, how it works and how it all looks like.

Physical server data:
System: Ubuntu 24.01 LTS
Memory: 256GB
Disks: RAID 1 (2pcs 480GB)

Deploying the system was not a problem, but the following difficulties arose - deploying the VM… I followed the video tutorial. I did exactly like this guy, it worked for him, but not for me.

I would be very grateful if someone would respond and help me with this problem!

Hello @duck

Welcome to this forum, hope we can help you in this journey.

My first suggestion would be check our tutorials (the “official” ones):

Where we cover basic operations.

Secondly, I would suggest to check our documentation.
Specifically the troubleshooting: Troubleshooting — OpenNebula 6.10.2 documentation

Ubuntu is well supported, so you should find a lot of info from our side. If you are using the graphic interface, you should be able to deploy the VMs without issues.

Let us know if you need more details or include more information on the steps you are following.

Cheers,
