[Kimchi-devel] [PATCH 1/3] Optimize VM update function

[Crístian Viana]

When updating a VM, Kimchi always fetches the current VM state
regardless of whether it will be needed.

Move the VM state fetching to block where it's needed. That way, Kimchi
will save a libvirt call when that result isn't important for the
operation.
