Refracta not booting in VM

I have a problem booting ISOs created with refractasnapshot on VirtualBox and qemu. While the ISOs boot fine on real hardware they fail to find/mount the root filesystem when using the VM. Last message before stacktrace:

[5.391171] List of all partitions:
[5.391302] No Filesystem could mount root, tried:
[5.391321] 
[5.391548] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Any idea how to work around this - or which kernel modules would have to been included to make it work?

Re: Refracta not booting in VM

Are you using a custom kernel? If so, compare your kernel config file to the one for the stock kernel to see if something is missing.

It may be something in the way the isos were made. I boot isos in qemu and vbox all the time. The only thing that doesn't work well is if the VM is set to do a uefi boot. In that case, I have to go into the efi setup and find the actual file to boot.

Take a look at /var/log/refractasnapshot.log or let me look at it.

Re: Refracta not booting in VM

I tried 4 different setups that all boot fine on real hardware but fail in Virtualbox and qemu:
- refracta_12.0_nox_amd64-20230829_1853.iso (the iso itself)
- devuan excalibur, iso created with refractasnapshot running on VirtualBox, stock kernel
- devuan chimaera with RTAI, iso created with refractasnapshot on real hardware, kernel 4.something
- devuan chimaera with PREEMPT-RT, iso created with refractasnapshot on real hardware, kernel 4.something

/var/log/refractasnapsot.log from excalibur run:

did you try to disable acceleration in VBox ?
this often brings succes in efi-booting

Re: Refracta not booting in VM

Do you mean 3D acceleration? That has no effect, neither turned on or off.

Re: Refracta not booting in VM

Oh, that log doesn't have enough in it. Please run refractasnapshot in debug mode. For the cli script, run refractasnapshot -d and if you used the graphical version, start it from a root terminal (or sudo) as refractasnapshot-gui -d

If the snapshots are being made on a system with a swap partition or an encrypted root filesystem, that might be causing a problem. I'd need to see the debug log to be sure.

Looking at the varied selection of isos that are not working, I'm thinking maybe it's a problem with virtualization. But that's a guess.

Re: Refracta not booting in VM

Theexcalibur iso is created inside VirtualBox, the 2 with RTAI and PREEMPT-RT are created on real hardware. Non of the installations have a swap partition nor a swapfile. But what puzzeles me is that the refracta iso from your site does not boot in the VMs, either.

Re: Refracta not booting in VM

The Refracta iso not booting in VM is weird. Check the sha256sum to make sure the download was good. But that doesn't explain the other failures.

The script output suggests that you have a resume file in your initramfs. (remove_resume=yes) but I don't see a corresponding 'rm -f ...resume' in the section under "edit_initrd".  Run lsinitramfs | grep resume $initrd where $initrd is the full path to the initrd in the excalibur iso. If you mount the iso, it will be in $mountpoint/live/initrd.img. Or you could retrieve it from the build host (assuming you set save_work=yes in refractasnapshot.conf). It would be in /home/work/iso/live/initrd.img.

You could also look in the build system for /etc/initramfs-tools/conf.d/resume and see what's in it. If it exists, make sure it says RESUME=none inside or delete it, and then run update-initramfs -u You only need the resume file if you want to resume from disk hibernation, and you usually don't want that in your snapshot.

Re: Refracta not booting in VM

So I redid every step ... result:

- refracta_12.0_nox_amd64-20230829_1853.iso boots, as you suggested it had the wrong checksum.
- RTAI and PREEMPT-RT don't boot in VM even after rebuilding. lsinitrd shows sane content.
- excalibur snapshot: lsinitrd just shows kernel microcode, nothing else.

It looks like my quck hack from https://dev1galaxy.org/viewtopic.php?pid=46256#p46256 is reponsible. The initrd is not unpacked correctly, so it's not rebuilt correctly. As refractasnapshop fails to unpack the initrd without the hack I'll need to dig deeper ...

Re: Refracta not booting in VM

There's a fix for refractasnapshot coming soon. Until then, another workaround is to remove the microcode package, make the snapshot iso, then install the microcode after you install a system on hardware. You could include the microcode packages in the iso to install them without a network connection if desired.

Re: Refracta not booting in VM

If you feel like testing, here's a modified refractasnapshot script that handles editing the initramfs better. I've tested it in a VM with encrypted lvm and then again in the same system after adding amd64-microcode and intel-microcode. I did this in daedalus, which is using zstd compression for the initramfs. Seems to work fine.

Copy the file, make it executable and run it from your current directory: 

sudo ./refractasnapshot -d

(or as root without the sudo)

Re: Refracta not booting in VM

So I had some time beween fireworks and breakfast smile

These are 2 patches for /usr/bin/refractashapshot and /usr/bin/refractashapshot-gui. They take care of these things:
- unpacking the initramfs using `unmkinitramfs` instead of doing it manually.
- unite 'early' and 'main' directories, if firmware made things worse.
- support "cpio archive" if initramfs is uncompressed.

Re: Refracta not booting in VM

Today I tried the new refractasnapshot  from excalibur repository (10.4.0). It still cannot handle the standard initrd from the excalibur kernel --> creation of initrd "works", but the created initrd is not bootable. Problem is still the same as described above, which is handle_cpio_extraction only extracts the microcode, not the initrd:

cpio_extracted/
├── kernel
│   └── x86
│       └── microcode
│           └── GenuineIntel.bin
└── main_filesystem

I still dont understand why the extraction of the initrd is not handled by "unmkinitramfs".

Anyway, here comes the patch to make refractasnapshot work with stock devuan kernel and uncompressed initrd (note:I don't care about refractasnapshot-gui - you'd need about the same patches there):
