Hello Natanael,
since this mail didn't get through, I'm sending this without the
kernel-image. Paul has received a copy of the image.
Starting the VM with following ram configs: 768MiB, 1024MiB, 2048MiB,
4096MiB and 8192MiB. All result in a kernel panic of the lts-kernel.
Without passthrough activated the lts-kernel starts with 4096MiB or more
memory. Bellow this value the kernel panics. The xen-pcifront module
gets loaded:

After upgrading to alpinelinux 3.11.3, the behaviour stays the same.
I tried to register with gitlab.alpinelinux.org, but had problems, see
below.

Yes, see attached files.

I haven't received the above post per mail nor have I received the
confirmation mail after registering with gitlab. I don't know if this is
an issue with my mail-provider, since there was no problem with the past
mails.
