@Cyrille I am seeing /sys/hypervisor/uuid matching dmidecode's Serial Number matching VM ID in xen orchestra.
dmidecode's UUID however is different from those three.

RE: Kubernetes Recipe VM failed to start - Raise Network Interfaces
@Cyrille It would be nice if (assuming integration with the ccm) there was a way to integrate the horizontal scaling tooling that exists to automatically scale up&down (setting minimum/maximum VM counts), but that is 100% out of scope for the CCM as is Im sure.
If you are asking for a dream wishlist tho, Id love if I could
- See what recipes Ive deployed & their current settings & general sum-stats
- have ability to adjust variables such as the ssh key, the current worker count or upgrade to a HA cluster (that is, increase master count to 3. (I understand that some of those are harder than others)
- Be able to upgrade the recipes as necessary (IE from 1.33-> 1.34).

RE: VM UUID via dmidecode does not match VM ID in xen-orchestra
Out of curiosity, I dumped the DMI into a bin and opened it up in a hex editor.
I am seeing ASCII of the ID, but also a variant encoded in binary. In both cases, its formatted as
0b08f477-491a-a982-23c4-d224723624ea.I believe the ASCII version is the one that gets populated into the serial number as it comes after ASCII encoded versions of the 3 lines above it in the decode.

RE: VM UUID via dmidecode does not match VM ID in xen-orchestra
@Cyrille Genuinly no idea unfortunately. The only thing I can think that I've done is that the VMs are being loaded in from a template.
I had to deploy new VMs through my terraform recently, and I AM still seeing an incorrect system UUID on those, so I can only guess its somehow the template?
I am also seeing the serial number from DMIDECODE match the VM ID in xen orchestra as well still.
