Hmm. I am on Fedora 38, and they just pushed out the 4.17.2 update to me
yesterday and qemu-system-i386 is working fine with it. This is the version
info on Fedora 38 that is working:

Xen version info from sudo xl dmesg on Fedora 38:

(XEN) Xen version 4.17.2 (mockbuild@) (gcc (GCC) 13.2.1 20230728 (Red Hat 
13.2.1-1)) debug=n Thu Aug 10 22:11:44 UTC 2023

Qemu version info on Fedora 38:

[user@fedora ~]$ qemu-system-i386 -version
QEMU emulator version 7.2.1 (qemu-7.2.1-2.fc38)
Copyright (c) 2003-2022 Fabrice Bellard and the QEMU Project developers

So, I think maybe you are using a different Qemu version that does not
work with Xen 4.17.2.

What version of Qemu are you using? Is it the one from the qemu-xen repo on
xenbits.xen.org, or one provided by Arch? In any case, Qemu 7.2.1 provided
by Fedora works fine with the newly released Xen 4.17.2 on my Fedora 38 system.

It looks like the Qemu for xenbits and tagged for Xen 4.17.x is using Qemu 7.0,
not 7.2, and it looks like the Qemu on xenbits added 8 more commits between the
4.17.1 and 4.17.2 tags. So you might try backing out those 8 commits if you are
building Qemu from the 4.17.2 tag in the qemu-xen repo on xenbits.xen.org.

Just a guess, though.
