Windows Subsystem For Linux Can Now Run On Very Large Servers, Experimental Sparse VHD

([Microsoft] 6 Hours Ago WSL2)


Microsoft yesterday released WSL 3.0.2 as their latest WSL update since last week's WSL3 release with "WSLC" for [1]promoting Linux containers on Windows to general availability . Some notable changes in WSL 3.0.2 include automatic virtual NUMA support and experimental support for sparse VHD storage.

WSL 3.0.2 introduces automatic virtual NUMA support for large WSL VMs. This came following a bug report from an Intel engineer that noted WSL was failing to launch on a host with more than 256 threads. With this automatic vNUMA handling, Windows Subsystem for Linux should now work out nicely on multi-socket servers.

The other notable WSL 3.0.2 is having experimental sparse virtual hard disk (VHD) creation support where disk space is only consumed for written data.

WSL 3.0.2 also has a fix for IPv4 forwarding, container fixes, container health notifications are added to WSLC events, and other fixes.

more details on the WSL 3.0.2 release via [2]Microsoft's GitHub .

Once there was a little nerd who loved to read your mail,
And then yank back the i-access times to get hackers off his tail,
And once as he finished reading from the secretary's spool,
He wrote a rude rejection to her boyfriend (how uncool!)
And this as delivermail did work and he ran his backfstat,
He heard an awful crackling like rat fritters in hot fat,
And hard errors brought the system down 'fore he could even shout!
And the bio bug'll bring yours down too, ef you don't watch out!
And once they was a little flake who'd prowl through the uulog,
And when he went to his blit that night to play at being god,
The ops all heard him holler, and they to the console dashed,
But when they did a ps -ut they found the system crashed!
Oh, the wizards adb'd the dumps and did the system trace,
And worked on the file system 'til the disk head was hot paste,
But all they ever found was this: "panic: never doubt",
And the bio bug'll crash your box too, ef you don't watch out!
When the day is done and the moon comes out,
And you hear the printer whining and the rk's seems to count,
When the other desks are empty and their terminals glassy grey,
And the load is only 1.6 and you wonder if it'll stay,
You must mind the file protections and not snoop around,
Or the bio bug'll getcha and bring the system down!
