Any Tipps?
Using qemu, bcause my corporate host is horribly restricted and changing net adapters is impossible. So I'm forced to usermode networking. Basically user network works. I'm using it for local software dev. Problem is its slowness.
Any idea/doc how to migrate slirp to passt for (hopefully) usable network performance? Current args:

-netdev user,id=n0,hostfwd=tcp:127.0.0.1:6379-:6379 -device=e1000,netdev=n0

The last time I heard about SLIRP was in the 1990s, when I was playing with waffle BBS systems!

#SLIRP #RetroComputing

@qyliss Similar situation with #VirtualizationFramework. I really could use user space networking with it, so I wrote a quick #Slirp backend for its UNIX socket target. Maybe you can reuse that same mechanism + tool with #CloudHypervisor - just implement a UNIX socket network backend 😁

This morning in our #EverythingOpen Speaker Spotlight series we have David Gibson of #IBM

#Ozlabs, talking #networking. #slirp - born of #PPP and #SLIP in the 90s - is still used - and has been re-implemented in #passt.

Some claim #SLIRP has poor performance. Would be interesting to do some kind of benchmark.
