1. Xen Type-1 hypervisor is smaller than KVM/QEMU.
2. Xen "dom0" = Linux/FreeBSD/OpenSolaris. KVM/bhyve also need host OS.
3. AMZN KVM-subset: x86 cpu/mem virt, blk/net via Arm Nitro hardware.
4. bhyve is Type-2.
5. Xen has Type-2 (uXen).
6. Xen dom0/host can be disaggregated (Hyperlaunch), unlike KVM.
7. pKVM (Arm/Android) is smaller than KVM/Xen.
> The Service Management Facility (SMF) is responsible for the supervision of services under illumos.. a [Linux] robust infrastructure product would likely end up using few if any of the components provided by the systemd project, despite there now being something like a hundred of them. Instead, more traditional components would need to be revived, or thoroughly bespoke software would need to be developed, in order to avoid the technological and political issues with this increasingly dominant force in the Linux ecosystem.Is this an argument for Illumos over Linux, or for translating SMF to Linux?
I don't know why you think none were mentioned - to name one, they link a GitHub issue created against the systemd repository by a Googler complaining that systemd is inappropriately using Google's NTP servers, which at the time were not a public service, and kindly asking for systemd to stop using them.
This request was refused and the issue was closed and locked.
Behaviour like this from the systemd maintainers can only appear bizarre, childish, and unreasonable to any unprejudiced observer, putting their character and integrity into question and casting doubt on whether they should be trusted with the maintenance of software so integral to at least a reasonably large minority of modern Linux systems.
