Hi all,
I have been wondering if I could manage to make Xen function on my
laptop, using as dom0 my Arch Linux installation. As far as I understood
there is no currently supported package in the AUR nor, obviously, in
the official repos. What to do? Compile it by myself! I went under all
the process, in particular

% PYTHON="/usr/bin/python2" ./configure --enable-stubdom \
               --enable-systemd --prefix=/usr

% PYTHON="/usr/bin/python2" NO_WERROR=1 make dist

% sudo PYTHON="/usr/bin/python2" NO_WERROR=1 make install

After that I manually added a grub entry to boot into my dom0
chainbooted by Xen.

And it seemed I succeeded, as far as I manage to boot into my system.
Everything seem to work, except that if I look at the features of my system

% sudo xl info

I get a discouraging indication on the total amount of ram I have on my

total_memory           : 1948
free_memory            : 120

while the total memory is (as measured from Arch booted without Xen)

% free -m
           total       used     free     shared  buff/cache  available
   Mem:    15924       8756     2206     737     4961        6100
   Swap:   8191        0        8191

What to do? I am very new to Xen, how can I debug it?

Thanks for your report.  Can you please attach the full output of "xl
info", as well as the output of "xl dmesg"?


I attach the output of xl info, xl dmesg in dom0 *and* dmesg in a normal
Arch Linux boot (without Xen).

Greetings and thanks for any help
