Re: [Xen-users] xen on centos6.5 issue with /proc/xen

["Fajar A. Nugraha" <list@xxxxxxxxx>]

Moving xen-devel to bcc, as xen-users should be the right place for
normal usage questions.

I assume you already solve this problem? From the link you wrote earlier:

"
Once that completes, check /boot/ for the presence of xen-4.2.1.gz and
edit your /etc/grub.conf to add a stanza like :

title xen
        root (hd0,0)
        kernel /xen.gz dom0_mem=256M,max:256M loglvl=all guest_loglvl=all
"

so comparing that and the grub.conf you get, the problem should be
clear enough. Since you don't boot xen.gz as kernel, you won't be able
to run xl.
