Dear all

I have the following use case:

I defined a flavor F for VMS with 10 VCPUs, 20 GB of RAM, 30 GB of root disk,
1 GPU XYZ.


I use PCI passthrough to manage GPUs.

I have only a XYZ GPU on my cluster (on a H hypervisor), so a VM using this
flavor F must be "placed" to the compute node H (and this is not a problem: I
know how to do that).

H is very large: it has a lot of RAM and cores, so it can host
other VMs that do not use GPUs.

How can I make it so that VMs without GPU can go on H, but there must be room
for a VM with flavor F (if it doesn't already exist)?

Thanks, and happy new year !

Cheers, Massimo
