xl dmesg buffer too small for Xen 4.18?

[Chuck Zmudzinski <brchuckz@xxxxxxxxxxxx>]

Hello,

I tested Xen 4.18~rc0 on Alma Linux 9 and my first tests indicate it works fine 
for starting the guests I manage but I notice that immediately after boot and 
with only dom0 running on the system, I get:

[user@Malmalinux ~]$ sudo xl dmesg
00bee72000-00000bee72fff type=7 attr=000000000000000f
(XEN)  00000bee73000-00000bef49fff type=4 attr=000000000000000f
(XEN)  00000bef4a000-00000bef4bfff type=7 attr=000000000000000f
(XEN)  00000bef4c000-00000befbafff type=4 attr=000000000000000f
(XEN)  00000befbb000-00000befbbfff type=7 attr=000000000000000f
...

I have noticed the buffer fills up quickly on earlier Xen versions, but never 
have I seen it fill up during boot and with only dom0 running.

Can increasing the buffer fix this? How would one do that?

Thanks
