Sorry if this isn't the best way to contact you.

Good luck!

Thank you for sharing that the libguestfs project exists @gordol; have you tried the command yay libguestfs?

[user11:42~]$ yay libguestfs
2 aur/libguestfs-git 1.42.0.r21.g4837698d8-1 (+0 0.00)
    Access and modify virtual machine disk image

    Python bindings for libguestfs

It appears that there are two versions of libguestfs via yay. To create the yay command, you can use either makeaurhelpers or makeyay which attempt to build yay in Termux PRoot, with or without QEMU emulated architecture support.

Because you found the solution we seek. Integrating this code with PRoot like the QEMU option should probably solve the mount issue.

I have tried yay guestfs multiple times. I am not getting a successful package build. Are you having any luck building the Arch Linux guestfs packages in Termux PRoot?

Look my answers above. No one here will bother to implement a tool for userspace image mounting. Please understand that possibilities of Termux maintainers are finite.

Those who really needs mounting as non-root can use QEMU system-mode.

Start with these:

• x86 (32bit): https://dl-cdn.alpinelinux.org/alpine/v3.12/releases/x86/alpine-virt-3.12.2-x86.iso
• x86_64 (64bit): https://dl-cdn.alpinelinux.org/alpine/v3.12/releases/x86_64/alpine-virt-3.12.2-x86_64.iso

Boot downloaded image (basic):

qemu-system-i386 -m 512M -nographic -cdrom alpine-virt-3.12.2-x86.iso

Modified to boot from URL with no local image:

qemu-system-i386 -m 512M -nographic -boot d -drive file=https://dl-cdn.alpinelinux.org/alpine/v3.12/releases/x86/alpine-virt-3.12.2-x86.iso,readonly=on,media=cdrom

In both cases output is printed directly to console as image supports serial line emulated by QEMU.
CTRL+a x to terminate VM.

Extending command line by switching to VirtIO devices (rng, nic, drives), increasing TCG cache (e.g. by -accel tcg,tb-size=512), using musl-based & non-systemd distributions like Alpine Linux makes execution under QEMU faster.

Arch Linux can be booted too, yet it is slower and ISO will require many RAM (1-2 GB, maybe more). Probably will have issues with text-only mode and you will need a VNC.

it is possible...

@gordol it seems to be possible to build libguestfs with command makelibguestfs; Can you please try command makelibguestfs and share your results?

silly bot. I'll try this soon, thanks @SDRausty
