I had some basic questions regarding KVM, and would appreciate any help:)
I have been reading about the KVM architecture, and as I understand
it, the guest shows up as a regular process in the host itself..
I had some questions around that..
Are the guest processes implemented as a control group within the
overall VM process itself? Is the VM a kernel process or a user
Is there a way for me to force some specific CPU/s to a guest, and
those CPUs to be not used for any work on the host itself? Pinning is
just making sure the vCPU runs on the same physical CPU always, I am
looking for something more than that..
If the host is compiled as a non pre-emptible kernel, kernel
process run to completion until they give up the CPU themselves. In
the context of a guest, I am trying to understand what that would mean
in the context of KVM and guest VMs. If the VM is a user process, it
means nothing, I wasnt sure as per (1).
