Problem w nested virtualization

[lDemoNl]

Good morning, guys! I've tried to install OpenStack on Proxmox, when I'm trying to start VM's in OpenStack I got error

Have you studied this: https://pve.proxmox.com/wiki/Nested_Virtualization ? Make sure everything is enabled at every layer (Bios, OS, VM).

Yes, I have. Another VM w nested virtualization works perfect.

Excellent information to share. In that case I suggest opening two terminals, running "journalctl -f" in one, and "qm start xxx" in another. There are likely additional helpful messages describing why the VM is failing.
