What happened?

After upgrading RHEL 9.3 to 9.4 the ventoy partition is not mounted with VTOY_LINUX_REMOUNT option. Probably RedHat backported some changes from the latest linux kernel to 5.14 (build 427 and next).
You can also reproduce this issue on the latest Boot ISO of CentOS Stream 9. Screenshot with detailed information:

This issue is also related to vtoyboot, on my VHD with RHEL 9.4 the ventoy partition is not mounted too.
I'm using latest CI release and vtoyboot-1.0.31 for VHD, Secure Boot is disabled.

You mean that it can work OK with RHEL 9.3 but can not work with RHEL9.4?

[Realex-fire]

Yes, @ventoy. Also it can work OK on RHEL 9.4 with kernel from RHEL 9.3.

You can try the CI release:

https://github.com/ventoy/Ventoy/actions/runs/9075095164

Also with vtoyboot-1.0.33:

Hello @ventoy.
Thanks for trying to fix it, but now the VTOY_LINUX_REMOUNT feature does not work on RHEL 9.4 and RHEL 9.3, dmesg log has not changed. I tested vtoyboot-1.0.33 with kernels from RHEL 9.4 and RHEL 9.3, and it doesn't work on my VHD.
vtoyboot-1.0.31 worked well with kernels from RHEL 9.3 but did not work with kernels from RHEL 9.4.

[ventoy]

I tested with Rocky linux 9.4 and it work OK.
I can not download RHEL 9.4, but I think it's similar to Rocky9.4.

[Realex-fire]

Yes, it does work on ISO (Rocky 9.4 and RHEL 9.4), but it doesn't work on my VHD with vtoyboot-1.0.33.
@ventoy, did you test vtoyboot-1.0.33 on Rocky 9.4 VHD or only the ISO?
I also noticed that on the latest CentOS Stream 9 VTOY_LINUX_REMOUNT feature doesn't work on ISO.

Edit: I noticed that you have not updated the vtoytool binaries in vtoyboot-1.0.33. I replaced them with 44fb9f4 but it didn't help.

[ventoy]

Try this CI release
https://github.com/ventoy/Ventoy/actions/runs/9146010459

I tested with CentOS-Stream-9-20240513.0-x86_64-boot.iso and it works OK.

And also I released vtoyboot-1.0.34 but I have not tested yet.

[Realex-fire]

Thanks, @ventoy. I tested vtoyboot-1.0.34 on my VHD (RHEL 9.4) and it still doesn't work. Maybe I need to provide some additional information?

[ventoy]

You need to make a fresh new VHD with new vtoyboot version. Or you can do as follows:

1. Change the xxx.vtoy file to its original name (e.g. xxx.vdi)
2. Boot the vhd file with the VM that created it before.
3. Download vtoyboot-1.0.34 and decompress it an re-run vtoyboot.sh inside the VM
4. Change suffix to xxx.vtoy and boot with Ventoy.

[ventoy]

I will test with a Rocky9.4 VHD later.

[ventoy]

I have just fixed some bug and released vtoyboot-1.0.35.
I have tested with Rocky9.4 VHD and it work OK, you can try.

Do as follows:

1. Use Ventoy to boot your VHD. (This time the VTOY_LINUX_REMOUNT option will not take effect)
2. Download vtoyboot-1.0.35 and run vtoyboot.sh
3. reboot and use Ventoy to boot your VHD agagin. (This time VTOY_LINUX_REMOUNT should work)

[Realex-fire]

Thanks @ventoy, but you probably forgot to upload the vtoyboot-1.0.35.iso file in the Releases section. Only the Source code is available now. I think I also understood what the bug was. Is it a $AWK typo? 🙂

[ventoy]

I have upload the vtoyboot-1.0.35.iso now.
