#virtualization

1 post1 participant0 posts today

A whole afternoon playing around... ok, no, that's not the word... It's been a whole afternoon banging my head against the wall that libvirt and its cousin virt-manager are.

I ended up going back to the ol' trusty shell script I use to fire up my FreeBSD and OpenBSD VMs. This is a desktop, not a server, so the VMs are on just for what I need to run on them (mostly checking portability of code I write) and then, they're shut down. No need for a socket listening in the background or a service to do who knows what.

The thing that really pissed me off was the permissions situation libvirt/libvirt-qemu got me into. I mean... wow, it silently set an ACL entry on my $HOME on its own to unilaterally give itself permissions inside my $HOME. Wow.

Apple just made #WSL a legacy technology.

Happy to recommend #macOS for container development. If performance and memory consumption against #Linux is negligible, then it will be my top recommendation for sure.

It's FOSS News · macOS Meets Linux with Open Source ContainerizationApple’s new open source Containerization project brings native Linux container support to macOS.

My planned mid-tier(ish) PC build for modest #gaming and #virtualization work while dual booting Windows and #linux.

Is it me or running VMs is still a pain in the butt on #ArchLinux?

You need to install Qemu which handles virtualization pretty well, but it doesn’t come with a GUI (still? really?). Fine, install Virtual Manager, but wait! You also need to enable a systemd service. Sure, done. Oh did you add your user to the libvirtd group?

Why isn’t there a single package that takes care of all of this out of the box? Or am I doing something wrong?

@k4m1 @stman yeah, according to the #RTL8139 #datasheet this is basically a very cheap 10/100M NIC designed #embedded systems and low-end/low-cost desktops, and for a device designed and sold in 2006 it made sense, given back then #Gigabit-#Ethernet and Cat.5 cabling was considered high-end.

  • And unlike contemporary / successor chips by #Intel like the famous #i210 (which is still offered as #i219 but mostly succeeded by the #i225 as a 2,5GBase-T version) is way cheaper, which pre-#RoHS - NICs being sold for like € 10 retail & brand-new....

The few issues known only affect like #Virtualization setups, a market this thing was never designed for (most likely also never tested against).

  • I'd not he surprised if a lot of cheap #ThinClients and other systems used these NICs because of the simplicity of integration, being a cheap 3,3V single-chip (+auxilliary electronics) solution and propably costling less than 10¢ on a reel of 10.000.

It's the reason why to this day we see #Realtek NICs being shipped instead of fanning-out & enabling #SoC-integrated NICs with a #MAC & #PHY instead: Because the auxilliary parts for those are more expensive than just getting a PCI(e lane) somewhere and plonking it down.

  • Maybe there have even been some really cheap, low-end #Routers / #Firewalls aiming at #SoHo customers back in those days, cuz back then 16MBit/s #ADSL2 was considered fast, and Realtek's NICs up until recently only delivered like 60-75% of the max. speed advertised, so by the time someone would notice, that gearvwould've been EoL'd anyway and those who did notice right-away never were the target audience to begin with.

Most modern NICs are more complex and demand more configuration / driver support...

Here is the new #Development #PC Build:

Went w/ integrated graphics for the time being & it is more than I need. Does #3dprinting slicing & drawing just fine, #virtualization just fine, #ffmpeg & the little bit of video editing I do. Blows the old i7-6700 w/ 16GB out of the water!
