Hi all,
I install Xen 4.8 on Ubuntu 17.04 (kernel is updated to 4.12). But I found only 1 CPU was detected.
I thought it is caused by some BIOS settings, so I enabled x2APIC in BIOS, unfortunately, Linux hangs during booting after printing "Loading initial ramdisk ...".
I have to disable x2APIC finally, but I only have 1 CPU when system is up. Does anyone encounter this issue?
The whole dmesg was attached. Xen related output.

Uuh, that is rather bad, I guess.
Just to be sure: can you please add "loglvl=all" to the xen boot
parameters? This would need to be added in your grub config file just
where "no-real-mode edd=off" is specified today (parameters for xen.gz).
Then repost the "xl dmesg" output, please.
Setting up a serial console would help, too, as you could then capture
the output with enabled x2APIC, which might help to find the reason why
Linux boot is hanging with this option.
Additionally you should check whether you can update the BIOS of the
test machine to a more recent version. It seems to be broken.

The dmesg with "loglvl=all" enable is attached.
I have updated BIOS to the latest one when I first encountered this issue.
But it does not help. The issue is still there.
Setting up a serial console is helpful for diagnosing x2APIC hang issue.
But the test machine is a remote machine, I cannot access its physical COM port.

I am going to assume this is due to not having:
b4d709b6e Use grub-file to figure out whether multiboot2 should be used for Xen.gz
a8e0f1adf Fix util/grub.d/20_linux_xen.in: Add xen_boot command support for aarch64
In the grub that he is using (Ubuntu?)
In other words he is using 'multiboot' instead of 'multiboot2'

If this is Ubuntu, my expectation is that this would require Xen 4.9 (which is
part of 17.10 but not yet released) and work on grub2 (which I will very
unlikely have the time for). Debian has not yet moved to Xen 4.9, so I would
doubt that it would work there either.

If Xen 4.9 does not work either, shall I try CentOS 7.13 instead? Or which Linux distribution is recommended?

I think Fedora 27 (currently in beta) is almost there (for x86_64 anyway).
It does have xen 4.9, but some manual steps are needed to get grub2
working using multiboot2. These are
* edit the grub.cfg file to use multiboot2 and module2 rather than
multiboot and module
* install the grub2-efi-x64-modules package and copy multiboot2.mod and
relocator.mod from /usr/lib/grub/x86_64-efi to
/boot/efi/EFI/fedora/x86_64-efi/ (which you probably need to create)
* add insmod multiboot2 to the relevant section in the grub.cfg file with
the other insmod lines.
Also watch out for useless sections in the grub.cfg file for a xen config
file rather than for xen itself.
I recently got xen working doing the above including running a domU guest,
but gdm didn't start and I haven't had a chance to work out if that is
related or not.

It won't generate the stanza.

Sadly not there as the ARM changes broke x86, see:

Yes. But does Xen 4.8 amd64 support "multiboot2"?

I wonder if you're trying to use xen.gz on an EFI system. Is so,
you want to use xen.efi there instead if firmware doesn't set
up enough compatibility things in EFI Mode, or enable CSM if an
option like this is provided by firmware setup.

Are you using a 32-bit EFI by chance?

I don't think so. I used "file xen.efi" to check and it indicates it is x86_64:
root@lis-f2334:~# file /boot/xen-4.8-amd64.efi
/boot/xen-4.8-amd64.efi: PE32+ executable (EFI application) x86-64 (stripped to external PDB), for MS Windows
Shall I build xen by myself?

The question was about your firmware, not xen.efi. The latter can
only be built as a 64-bit binary right now. Hence ...

... no, unless you would first invest quite a bit of work into getting
Xen to also build as a 32-bit EFI binary (and this of course would
help only if indeed your EFI implementation is a 32-bit one).
