qemu-xen is unavailable

[Christian Kujau <lists@xxxxxxxxxxxxxxx>]

Hi,

after upgrading from from Xen 4.15.1 to 4.16.0 (Dom0 running on Alpine 
Linux, Edge), the following is printed when starting a DomU:

-------------------------
# uname -rm
5.15.10-0-lts x86_64

# xl create -f /etc/xen/debian.cfg
Parsing config from /etc/xen/debian.cfg
libxl: info: libxl_create.c:121:libxl__domain_build_info_setdefault: qemu-xen 
is unavailable, using qemu-xen-traditional instead: No such file or directory
-------------------------

The domain is started just fine, no ill effects so far. But I'm wondering 
on the meaning of that message. I found a patch[0] from 2019 where this 
message got introduced, but the comment above just states the same, but I 
can't figure out _why_ qemu-xen is unavailable.

Does anyone has an idea what this is all about?

Thanks,
Christian.
