Installing Void Linux inside Qemu running nested on a Debian 12 KVM VPS!

Does anybody here use Void Linux with musl libc?

I thought Void might be fun to try! I never tried Void before!

Here below is the beginning of a nested install of the musl libc version of Void inside a KVM VPS running Debian 12.6.

I wonder if I will be able to complete the install successfully. . . .

  • Make an ssh tunnel from the local machine to the VPS:
ssh [email protected] -L 5900:localhost:5900
  • In the local VNC viewer:
localhost:5900

I hope everyone gets the servers they want!

    I ran the Void installer shown in the screenshot above. Now I seem to have an installed system which can update itself, reboot successfully, run sshd, install software, and run some of Yabs.

    The Qemu command I am using for booting the installed system differs slightly from the above command to launch the installer.

    Run inside tmux:
qemu-system-x86_64 \
-cpu host \
-enable-kvm \
-m 2048 \
-drive file=void.qcow2 \
-net nic -net user,hostfwd=tcp::8080-:8080,hostfwd=tcp::42397-:42397 \
-vnc 127.0.0.1:0 \
-boot c

    Here's basic info on the installed and updated Void Linux system.

    Here is part of a Yabs. The disk speeds are low, partly because I'm using emulated file I/O in Qemu. I am guessing that the network speeds are low partly because I am using Qemu default user networking (slirp). Apparently musl libc doesn't support locales. Additionally, the Geekbench 6 called from Yabs doesn't seem to work. Maybe that's also a result of musl libc.

    Here is a fun page comparing musl with glibc and other mibc implementations, but unfortunately not including BSD libc in the comparison. If anybody knows of a comparison which includes musl libc, glibc, and BSD libc, please share a link.

    I have tried to be fair and objective, but as I am the author of musl, that may have influenced my choice of which aspects to compare.

    :p
