CentOS + Xen is driving me nuts! I came across a nasty issue, which makes me (try to) pull my hair:

xm create -c whateverdomain
Some pygrub output…
and then.. Error: (4, ‘Out of memory’, “xc_dom_boot_mem_init: can’t allocate low memory for domain\n”).

Googling this for a few hours and actually trying different distros (even trying out Lenny!) gave me nothing. One post (that I finally found) says this issue maybe caused by trying to start an image (created on a 64 bit Xen) on a 32bit Xen.

So now I am installing CentOS 5.3 64bit on my Vaio laptop. It comes with a Centrino (Core 2 Duo I believe).

and runs like a charm
