Guix boot issue on Hyper-V

Hello,

I'm trying to run Guix System 1.4.0 in a Hyper-V environment with no window manager.

I'm using Generation 1 instead of Generation 2 is because Generation 2 has an error when running the installation media:

```

waiting for partition '31393730-3031-3031-3139-333333313833' to appear...? [x21 times]

ice-9/boot-9.scm:1685:16: In procedure raise-exception:?

failed to resolve partition "31393730-3031-3031-3139-333333313833"?

```

I'm able to install with Hyper-V Generation 1 and it generally works out of the box and even after doing pull and upgrade via:

```

guix pull?

sudo guix system reconfigure /etc/config.scm?

guix upgrade?

```

Early on I noticed that it would sometimes hang while booting, but a couple of reset attempts and waitin usually fixed it. However now I am no longer able to boot into the system.

At boot I get this log near the end:

```

udevd[85]: no sender credentials received, message ignored?

piix4_smbus 0000:00:07.3: SMBus base address uninitialized - upgrade BIOS or use force_addr=0xaddr?

Error: Driver 'pcspkr' is already registered, aborting...?

```

Did some searching and found issues https://issues.guix.gnu.org/44257,https://issues.guix.gnu.org/48343, and https://issues.guix.gnu.org/55006 so I tried adding nomodeset? and blacklisting pcspkr from the linux argument list but this did not allow me to reach the login.

I get the following messages with quiet? removed:

```

psmouse serio1: trackpoint: failed to get extended button data, assuming 3 buttons?

input: TTPS/2 IBM TrackPoint as /devices/platform/i8042/serio1/input/input6?

hv_balloon: Max. dynamic memory size: 1048576 MB?

```

(attached as boot-error-loud.png?)

I've tried a few other things like locking the memory to 4 GB (instead of dynamically set with 2 GB) and blacklisting psmouse?, but with no success.

Debian 12 works without issues but I want to dump Debian and move all my systems to Guix. It's able to use Debian on Hyper-V Generation 2, maybe that has something to do with it?

Is there any way to resolve this Hyper-V Generation 1 boot issue?

Alternatively, is there a way to make the installer work on Hyper-V Generation 2?

And is there also a way to persist these logs so I can try reinstalling Guix and compare the logs? I'm able to access the filesystem via a TinyCore liveCD.

Thanks,

Sorry for all the extra question marks. Those were inserted because I formatted the preceding word as monospace. Will be sending plaintext in the future.

Fixed by switching to QEMU + virt-manager.

How can I close this issue?

I don’t think your attempt worked, I added “-done” to the debbugs email address.
