I was shocked when I discovered /proc/sysinfo on a z system, and that even inside KVM machine it exposes the LPAR, z/VM, KVM information. And that this information is stored, is nested, and is passed through to inner layers. I found it extremely insecure, as typically I expect privilege separation after each layer of virtualization - as in a public cloud guest user, should not be able to introspect the underlying virtualisation middle layers (e.g. xen) or the bare metal. I expect a typical bare-metal -> virtualization -> containerization deployment will not have the same sysadmin managing / supervising each of those layers. I expect datacentre remote-hands sysadmin; devops; developers to have segregated access to these things. However, after working with z systems a bit more, I realized that the physical security and access modeling is very different. In effect, one typically has a very limited number of people accessing the mainframe, whilst sharing many hats. Hence the mindset that this is sensitive information to expose from one context to a nested one is simply not there. I do agree that /proc/sysinfo is useful and nice. But also something to _not_ be extended, and to _not_ be ported to other architectures. Can't really be removed, or change output, cause it is ABI effectively. (There are inverse examples too, for better or worse, e.g. UEFI access is more open and API accessible from userspace than HMC is from LPAR) Regards, Dimitri. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For more information on Linux on System z, visit http://wiki.linuxvm.org/

I have proposed upstream systemd to not use color by default on z/VM, as it seems that the most recent HMC does strips escape codes correctly in the operating systems messages window. The HMC ascii terminal displays everything correct, and so does QEMU/KVM terminals. So far I believe it's just z/VM that fails to render dmsg [ ] and strip escape codes. I've tried proposing to systemd to not use color in LPAR/ZVM modes, but that was rejected see https://github.com/systemd/systemd/pull/3025/files & https://github.com/systemd/systemd/pull/3025 & https://github.com/systemd/systemd/issues/3115 and https://github.com/systemd/systemd/commit/32391275c02715f76232128c49b19bb619cd9463 Ideally this stuff should work correctly automagically.

However, over time this will be made available in 16.04 LTS as well: - qemu in zesty (17.04) is on par feature wise with IBM KVM for z, and will be available on 16.04 LTS via Ubuntu Cloud Archive. - linux in zesty (17.04) is expected to ship with v4.10 kernel which has all the kernel/qemu features that are present in IBM KVM for z, the updated kernel will be available on 16.04 LTS via linux-hwe kernel in the 16.04.3 point release. Please note that Ubuntu is a complete distribution, and you will find out of the box support for a lot of software; IBM KVM for z product is by intent only a single/limited purpose distribution. All features present in IBM KVM for z have been contributed upstream. Most of them are already in Ubuntu, and the outstanding bugfixes and features will be available in due course. The support timeframe for Ubuntu 16.04 LTS is until April 2021. I do not know what the support/upgrade time frames for IBM KVM for z are, e.g. maybe ask your IBM reps until when IBM KVM for z will be supported. You can find a few Ubuntu and IBM KVM for z developers on #ubuntu-s390x on freenode as well if you have more technical questions to discuss. > I am looking for gui tools to help me remotely administrate linux. > > Can anyone recommend some tools? > In terms of lightweight graphical tools, I personally use virt-manager on my Ubuntu desktop and connect to libvirt daemon via ssh running on Ubuntu s390x.

There is no checking of CPU ids etc. Simply the compiler default architecture is set to zEC12 across the board, meaning that glibc, kernel, and most binaries rely on zEC12 only instructions. I do not believe these are at all available, in full, on non zEC12 hardware. In other words it's not possible to "fake" CPU id in Hercules / zPDT / z/VM / z/KVM, as things simply segfault / fail with illegal instructions at runtime.

I like that it can [de-]serialize and persistent and manages cio_ignore too. And one can enable devices ahead of time too (e.g. when said device does not exist on the system yet). It's really good, and scales well, during development cycle we saw races and bugs with older hwup/down tooling, which chzdev complete replaces, by generating efficient rock solid modern udev rules.

Anyway: us.ports.ubuntu.com ports.ubuntu.com Should work as hostnames, with no further protocol/ports/etc. It would complete install over HTTP, using default port, on either ipv4 or ipv6.

On the thank you page, after the form completion there is a link to full downloads with all check sums and GPG signatures. Look for "If it doesn’t, or for alternative options ***visit the download page***". Click there to access check-sums & GPG signatures.
