Doesn't work on Ubuntu 16.04/xenial #14

Thank you for your tool, but unfortunately it doesn't work for me

And unfortunately all I can see is

And if I create img for QEMU by hands (converting img from vmdk) everything works.

I can attach generated *.img file if needed.

The text was updated successfully, but these errors were encountered:

Hi!

My guess is that the TCG doesn't support requested feature: CPUID.01H:ECX.vmx [bit 5] up there is at fault: QEMU does not seem to fully work in TCG mode (which is the default) in your environment. I Googled a bit for that message but no real clue on why it would fail, yet. What environment are you running this in: what architecture, host/chroot/container/VM(if so which type), ...?

My guess would be that you are running Ubuntu in a virtual machine that does not have nested VMX enabled.

Else and if you have KVM around, please give this patch a try:

PS: If that Fallout theme happens to be public, please share a link. I'd be curious and I didn't find it using Google...

mskonovalov · 2017-03-21T08:41:52Z

Hi, thank you for reply.
I use Ubuntu 16.04 on my HP laptop.
I'll verify your suggestions a bit later.

P.S. https://github.com/mskonovalov/grub2-theme-fallout

Getting this :/ (After the patch)

hartwork · 2017-03-29T20:57:38Z

With that patch mentioned above or without?
What environment are you running this in: what architecture, host/chroot/container/VM(if so which type), ...?
Are you able to boot other things with KVM/QEMU, say an Ubuntu live CD, or is it just grub2-theme-preview?

Best, Sebastian

regalstreak · 2017-03-29T21:06:18Z

I don't have an idea about QEMU currently. This is really my first time at tinkering around with it.
After the patch, yeah.
Running it on host: Intel(R) Core(TM) i7-4510U CPU x64 (dunno much about virtualisation too, first time!)

I'll try running something else. Didn't do it till now.

BTW I did this:

Can run Ubuntu 16.04 with QEMU. So maybe this is a grub2-theme-preview issue.

This works good:

regalstreak@rsubuntu:~/Development/QEMU/ubuntu$ ls
ubuntu-16.04-desktop-amd64.iso  ubuntu.img

EDIT:
Actually man, if this is not an active project, it's alright. I can reboot to test the theme or i'll just look at your blog and make that manually lol. Don't tire yourself up on it! :D

hartwork · 2017-03-29T21:21:49Z

Sot it boots fine despite warning: TCG doesn't support requested feature: CPUID.01H:ECX.vmx [bit 5] in the output in your case?

hartwork · 2017-03-29T21:26:32Z

Does

grub-mkrescue --output boot.iso
qemu-system-x86_64 -cdrom boot.iso

show an interactive grub prompt grub> with a bit of text above in QEMU?

hartwork · 2017-04-02T12:52:58Z

@regalstreak any news?

regalstreak · 2017-04-05T11:22:16Z

@hartwork i have university entrance exams coming up so I haven't looked. I'll try on 13th and revert. 👍

hartwork · 2017-04-05T20:12:34Z

Good luck, see you later. Thanks for the update!

Yes, it works

Maybe I could share img file that is created?

Hello
I'm on Ubuntu 17.10 and grub2-theme-preview does not work for me. No errors

hartwork · 2017-12-20T16:36:46Z

I hope to find some time for working on this issue again before January.

regalstreak · 2017-12-25T18:49:57Z

I got over it and am using the drab black normal theme on grub2 since may

to help debugging issues like #14.

Without i386-pc available, the resulting rescue image could cause error "Could not read from CDROM (code 0004)" during boot in QEMU. Related to issue #14.

hartwork · 2017-12-29T19:59:57Z

I played with (a pristine chroot of) Ubuntu 16.04 myself now. Without package grub-pc-bin installed, QEMU failed to boot the rescue image saying Could not read from CDROM (code 0004). After sudo apt-get install grub-pc-bin it booted fine. So I enforce use of platform i386-pc in the code now and produce an error if it's found missing.

I consider this ticket fixed. If you still run into issues, please make new tickets (with terminal output, Ubuntu version, and a screenshot of te QEMU window). Thanks!
