[Qemu-devel] Are FreeBSD guest images working?

[Peter Xu]

Hi, the list,

I am trying to boot a FreeBSD guest but failed.  It hangs at the
kernel booting phase:

/boot/ker]el/kernel text=0x14ed860 data=0x132538+0x4baa68 syms=[0x8+0x159ee8+0x8
Booting...
(nothing more)

It's just as simple as downloading the image and boot so I can't think
of anything strange within my procedures so far:

https://wiki.qemu.org/Hosts/BSD#FreeBSD

I also tried the latest image here:

https://download.freebsd.org/ftp/releases/VM-IMAGES/11.2-RELEASE/amd64/Latest/FreeBSD-11.2-RELEASE-amd64.qcow2.xz

but it's having the same problem as 11.0.

Am downloading an fresh ISO, but before I continue I'm just curious on
whether anyone is using these images and whether there's quick answers
to what I have encountered.

Thanks in advance,

I use 'make vm-build-freebsd' which works, but the image comes 
pre-installed.

Hi,
I have one VM with FreeBSD-11.2-RELEASE-amd64.qcow2 image and it works
fine under qemu 2.12.1. But it's controlled by libvirt + virt-manager,
so it has a bit more cmdline arguments than in wiki.

In general, those images has serial console disabled by default.

Creating the following file in VM fs:
[root@freebsd ~]# cat /boot/loader.conf 
boot_multicons="YES"
boot_serial="YES"
comconsole_speed="115200"
console="comconsole,vidconsole"

allows me to successfully boot with:
# qemu-system-x86_64 -machine accel=kvm -m 2048  \
      -cpu host -enable-kvm -nographic -smp 2 \
      -drive if=virtio,file=./FreeBSD-11.2-RELEASE-amd64.qcow2,format=qcow2

Best regards, Ilya Maximets.

Well...  I never expected this. :)

SPICE worked for me now, and I tested your serial configuration, it
works as well! (though there'll be some display issue with the boot
logo before the kernel starts, but it's not a big problem)

Thanks!

It's because I'm always with no-gui mode and FreeBSD images has no
serial enabled by default.  I was possibly spoiled by the nice
virt-builder before with consoles setup already for all Linux guest
images.  Thanks for answering!

I'm coming to the game late...

I run FreeBSD in qemu all the time, but I build images from source to test
the boot loader and it's all serial and my test scripts are tuned to that.
I rarely use the pre-built images, however.

If there's ways that we can build images that work better than we're doing
right now to make the experience better, like making sure we enable the
dual console support for them... We're late in our release cycle, but if
what we need to change is what I think we need to change, we still have
time for it.

In the mean time I'll read through wiki and see if there's anything
obviously wrong...

I would guess there aren't many people like me to prefer booting a VM
using console, though I agree that it'll be nice if we put something
into the prebuilt images like what's suggested by Ilya (and so far I
don't see anything bad with that):

        [root@freebsd ~]# cat /boot/loader.conf
        boot_multicons="YES"
        boot_serial="YES"
        comconsole_speed="115200"
        console="comconsole,vidconsole"

Anyway, thanks for your work on either the wiki or the images, they
are really helpful to people like me.

As it happens I would have preferred the instructions on
the QEMU wiki to work with a pure serial console but was unable
to get that working so defaulted to graphics. (I didn't try very
hard: x86 in general is much worse for getting serial boot
working than other architectures, partly because of the BIOS.)

We use the official qcow2 images for FreeBSD for libvirt/virt-tools
CI[1] and not having serial console/ssh access by default is a bit
annoying, as it requires the administrator/developer to log in using
the graphical console, configure the guest OS according to [2], run
an Ansible playbook which, among other things, will enable serial
console access[3], and finally remove the graphical console.

If official qcow2 images could have serial console access turned on
by default, that would make the process a lot more convenient for us.

Just another data point :)

qemu-system-x86_64 -machine graphics=off should work reasonable well
these days.

That's what I use to test the boot blocks / boot loader :)
