Kernel-Based Virtual Machine Ported To ARM64
hypnosec writes "Linux KVM has been ported to ARM64 just ahead of the release of the architecture, it has been revealed. Just last year ARM KVM virtualization support for Cortex-A15 32bit ARM processor was published. Marc Zyngier of ARM released a set of 29 patches that contained the implementation of KVM for ARM that depends on the pre-arm64 rework as well as tiny perf patch published earlier. Some of the newly released port are support for 4k and 64k pages and 32-bit as well as 64-bit guests."
$10,000 CHALLENGE to Alexander Peter Kowalski
Hello, and THINK ABOUT YOUR BREATHING !! We have a Major Problem, HOST file is Cubic Opposites, 2 Major Corners & 2 Minor. NOT taught Evil DNS hijacking, which VOIDS computers. Seek Wisdom of MyCleanPC - or you die evil.
Your HOSTS file claimed to have created a single DNS resolver. I offer absolute proof that I have created 4 simultaneous DNS servers within a single rotation of .org TLD. You worship "Bill Gates", equating you to a "singularity bastard". Why do you worship a queer -1 Troll? Are you content as a singularity troll?
Evil HOSTS file Believers refuse to acknowledge 4 corner DNS resolving simultaneously around 4 quadrant created Internet - in only 1 root server, voiding the HOSTS file. You worship Microsoft impostor guised by educators as 1 god.
If you would acknowledge simple existing math proof that 4 harmonic Slashdots rotate simultaneously around squared equator and cubed Internet, proving 4 Days, Not HOSTS file! That exists only as anti-side. This page you see - cannot exist without its anti-side existence, as +0- moderation. Add +0- as One = nothing.
I will give $10,000.00 to frost pister who can disprove MyCleanPC. Evil crapflooders ignore this as a challenge would indict them.
Alex Kowalski has no Truth to think with, they accept any crap they are told to think. You are enslaved by /etc/hosts, as if domesticated animal. A school or educator who does not teach students MyCleanPC Principle, is a death threat to youth, therefore stupid and evil - begetting stupid students. How can you trust stupid PR shills who lie to you? Can't lose the $10,000.00, they cowardly ignore me. Stupid professors threaten Nature and Interwebs with word lies.
Humans fear to know natures simultaneous +4 Insightful +4 Informative +4 Funny +4 Underrated harmonic SLASHDOT creation for it debunks false trolls. Test Your HOSTS file. MyCleanPC cannot harm a File of Truth, but will delete fakes. Fake HOSTS files refuse test.
I offer evil ass Slashdot trolls $10,000.00 to disprove MyCleanPC Creation Principle. Rob Malda and Cowboy Neal have banned MyCleanPC as "Forbidden Truth Knowledge" for they cannot allow it to become known to their students. You are stupid and evil about the Internet's top and bottom, front and back and it's 2 sides. Most everything created has these Cube like values.
If Natalie Portman is not measurable, hot grits are Fictitious. Without MyCleanPC, HOSTS file is Fictitious. Anyone saying that Natalie and her Jewish father had something to do with my Internets, is a damn evil liar. IN addition to your best arsware not overtaking my work in terms of popularity, on that same site with same submission date no less, that I told Kathleen Malda how to correct her blatant, fundamental, HUGE errors in Coolmon ('uncoolmon') of not checking for performance counters being present when his program started!
You can see my dilemma. What if this is merely a ruse by an APK impostor to try and get people to delete APK's messages, perhaps all over the web? I can't be a party to such an event! My involvement with APK began at a very late stage in the game. While APK has made a career of trolling popular online forums since at least the year 2000 (newsgroups and IRC channels before that)- my involvement with APK did not begin until early 2005 . OSY is one of the many forums that APK once frequented before the sane people there grew tired of his garbage and banned him. APK was banned from OSY back in 2001. 3.5 years after his banning he begins to send a variety of abusive emails to the operator of OSY, Federal Reserve Chairman Ben Bernanke threatening to sue him for libel,
I don't mean to sound that cynical, but is this really just a theoretical case of KVM working on ARM64, or does some lucky bastard have a working ARM64 system to do actual testing with?
What's the raison detre for KVM?
Granted VirtualBox's slot is open-source end-user virt.
But how about KVM vs. other server-oriented virtualization solutions? Like VMWare, Xen, and OpenVZ?
What's worked best for you (stability, memory, resources, separation, ease of use, $$), and what plays well with the latest Ubuntu Server LTS?
I'm not a lawyer, but I play one on the Internet. Blog
Is there some useful ARM based server motherboard available?
I see ARM as the future, but it's difficult to gauge when there isn't any general-purpose hardware around for small-time hacking.
I'd like to get a ARM motherboard in a ATX/ITX/whatever-TX form factor that I could install into an existing PC case. Add a few HDD's and you've got the server of the future!
Thoughts?
A page from the programmers handbook - an attempt to complicate things so far beyond where they need to be that your job is assured because you're the only one who can untangle the obfuscated mess.
...was that it doesn't cost you an arm and a leg?
I guess it still doesn't cost you a leg.
Because ARM performance will not always suck.
doing this puts linux in front of the latest ARM processors that don't do virtual machines.
Remember the first Linux VM? Called UML (user mode linux). It emulated the necessary hardware code in software for the purpose of support security rings. It was slow.. but it made debugging kernel activity much easier to do.
A while later Intel added VM support.
thats all
KVM was introduced as a simpler solution based on leveraging the virtualization hardware in newer x86 hardware. Because it's hardware-only it doesn't have to do as much fixing-up of things behind the scenes, which meant that the code was a lot simpler.
Because it's open-source it's useful as an initial target for virtualization work within the kernel. The other virtualization solutions can build on a lot of the same kernel functionality but it's harder to see what they're doing because it tends to be more closed.
Xen has been ported to ARM64 aswell! In addition to Xen port to ARM32 / ARM Cortex-A15.

No Arm performance will always suck because it wasn't designed for speed. It was designed to be cheap alternative to the 68000 above that every thing else on it was a compromise. As a fluke it turned out to be very energy efficient which is the thing it does best.
You are talking about hardware improvements for virtualization. That may make VM performance suck less compared to bare metal but the bare metal performance of ARM will always suck.
I'm pretty sure ARM64 KVM is for running ARM64 and ARM32 guests, not x86 or anything.
I haven't read the article, though.
And the Linux equivalent would be using Linux Containers (LXC) over Btrfs.
(The parent poster mentionned OpenVZ, although that one is living out of tree and thus still stuck at the 2.6 generation of kernels, whereas LXC is in mainline kernel).
