Hi
Today we have the KVM devel call. We discussed how to create machines
from QMP without needing to recompile QEMU.
Three different problems:
- startup QMP (*)
not discussed today
- one binary or two
not discussed today
- being able to create machines dynamically.
everybody agrees that we want this. Problem is how.
- current greensocs approach
- interested for all architectures, they need a couple of them
what greensocs have:
- python program that is able to read a blob that have a device tree
from the blob
- basically the machine type is empty and is configured from there
- 100 machines around 400 devices models
- Need to do the configuration before the machine construction happens
- different hotplug/coldplug
- How to describe devices that have multiple connections
- problem realizing objects that have inter-dependent link properties
Mirela, you mention an issue with TYPE_CPU_CLUSTER / TYPE_CPU, is that
an example of this qom inter-link problem?
Yes, for cluster/cpu specifically it is the parent-child relationship
between objects.
As the discussion is quite complicated, here is the recording of it.
Later, Juan.
