#Linux #Tor #Tails #QEMU #KVM #VirtualMachine #隱私 #資安 #虛擬機
今天第一次用Linux才有的QEMU/KVM虛擬機安裝Tails Linux系統,打開Tor瀏覽器上網發文.
以前2019那一年自學只有安裝Tails系統到USB上用,2020年剛開始學KVM虛擬機操作也沒安裝Tails認真用過.
結合使用Tails和KVM虛擬機,Tails本來已經很高的安全性和隱私被KVM虛擬機再往上提昇.
我選擇的HostOS也是Debian-Base,雖然不是專門為安全性和隱私設計的發行版,不過它比Lubuntu更輕量化減少攻擊面.
今年秋天到明年我打算日常使用虛擬機提昇相關技術熟悉度,將虛擬機實際應用於資安.
我需要閱讀編程隨想的掃盲操作系統虛擬機系列文章,複習曾經學過的部份及加強還沒學起來實際運用的內容.
學起來後會再找時間寫相關Blog文章放在CodebergPages託管的個人網站,未來想複習就能直接讀自己的文章,運用費曼學習法教其他人也可以讓我學得更扎實.

Kernel-based Virtual Machine (KVM) is virtualization technology for Linux.

Oracle VirtualBox alternative.

KVM allows Linux to function as a hypervisor that runs isolated virtual machines.

Hypervisor: https://wikipedia.org/wiki/Hypervisor

SELinux establishes security boundaries around virtual machines.

Use any storage supported by Linux.

Manage virtual machines via the Virtual Machine Manager desktop interface.

#Parallels Desktop 26 offers a lot to enterprise users, a little to consumers

Now THIS is how I like it. 86Box 5.0 has quickly taken over my existing virtual machines without any issues. Everything seems to be working fine and its new VM manager is looking really nice!

P. S.: First impression: PS/2 mouse support feels so much smoother than before!

I'm writing a series of blog posts, in which I write a #bytecode #compiler and a #virtualMachine for arithmetic in #Haskell. We explore the following topics in the series:

- Parsing arithmetic expressions to ASTs.
- Compiling ASTs to bytecode.
- Interpreting ASTs.
- Efficiently executing bytecode in a VM.
- Disassembling bytecode and decompiling opcodes for debugging and testing.
- Unit testing and property-based testing for our compiler and VM.
- Benchmarking our code to see how the different passes perform.
- All the while keeping an eye on performance.

The second post of the series that focuses on writing the #compiler is now out: https://abhinavsarkar.net/posts/arithmetic-bytecode-vm-compiler

Alright, Fedi of the verse. Got a tech question for you that I seemingly cannot find an answer for, so I come to y'all nerds!

I'm currently trying to make an aarch64 VM on x86_64 hardware, which afaik, is entirely possible. I wanna emulate Windows on Arm, basically.

I'm using QEMU/KVM & Virt Manager, and I can get to the "posting" process, at which point it just... maxes out ONE core of my CPU, forever, until I close virt-manager. I've no idea why?

Any takers? #Tech #AskFedi #VirtualMachine

#RUNBSD! But BoxyBSD now also starts to support #Linux! We're starting soon with the Linux support for already present users, offering free boxes:

* #AlmaLinux
* #Alpine
* #Debian
* #Devuan
* #CentOS
* #Fedora
* #Gentoo
* #OpenSuse
* #OpenEuler
* #RockyLinux

Just next to our core OS like #FreeBSD, #OpenBSD, #NetBSD, #MidnightBSD and #DragonflyBSD (and #illumos). This should also make the step easier to compare and test different scenarios where BSD provides a different behavior compared to Linux systems.

Thanks to @gyptazy for the implementation!
