[Trisquel-users] Kernel Panic Using Virt-Manager on Trisquel and libreboot
I am attempting to install PureOS 8.0 (beta) on a libreboot Taurinus laptop running Trisquel 8 using virt-manager. Everytime I try to create the PureOS virtual machine, I get a black screen filled with a whole lot of meaningless stuff on it. The screen freezes so all I can do is restart the laptop. Each time I've attempted this, the "stuff" on the frozen black screen is different, the only thing that appears to be constant is the term "Kernel Panic". I tried searching online to figure out what this means and what I should do, but there doesn't seem to be much related to Trisquel and libreboot, and what I did find was FAR above what I am able to comprehend. (I am NOT a computer person, I'm just an ordinary guy who would like to make this work.) How can I find out - in terms I can understand - what is wrong, and what I should do? Thanks in advance for any help.

ah, the ol kernel panic, yep, I have had that happen on my x200 when I use virtual machines. It may be related to kvm. not sure though.

That is a bug in the CPU. The only solution for this us using a different CPU. The Vikings D16 and the Talos II do not have that problem.

Hi, I'm having the same problem. Have you found any solution or have clues about this problem?

Indeed, it seems to be spefic to one piece of software. I would try the
following, in order:
1. It's been months since I don't use virt-manager, but I suggest you to
get information from virt-manager itself, if I'm not mistaken there
are useful logs such as "${HOME}/.virt-manager/virt-manager.log" and
"/var/log/libvirt/qemu" --- this last one has log files for each
virtual machine. If unlike me, you want to use the forums instead of
the mailing lists, and want to attach the log files, make them have
the .txt extension instead of .log.
2. Try disabling KVM for that specific virtual machine in virt-manager.
3. Upgrade the kernel of the host system (Trisquel 8, I assume), use
jxself's Linux Libre repository to do this.

You're welcome! Happy hacking! :D

Re: [Trisquel-users] Kernel Panic Using Virt-Manager on Trisquel and libreboot
I had this issue with a x200 flashed to Libreboot two years ago. When I ran qemu with --enable-kvm or when I used libvirt (with virt-manager), it freezed and I was forced to hard shutdown. The x200 had a a P8400 Core 2 Duo, I don't remember the batch.. but on my current x200 (with a P8600) and latest Libreboot stable (september 2016), kvm works great with Linux / BSD / Window$ VM. I'm not sure if the thing was CPU related.. I don't use Trisquel anymore these days.. You can disable KVM but virt will be slow as hell though. Try to use jxself's linux-libre-lts kernel and make sure you're running latest libreboot stable first as ADFENO suggested.
