I''ve installed an hypervisor and an hypervisor with pae support. Both
configurations uses the same modules but only the kernel with pae
support boot. Why?

If you want to run non PAE hypervisor, you have to run a kernel built without PAE support.

You can verify the PAE state for a kernel by looking in the corresponding config file, normally saved in /boot with the kernel.> -----Original Message----- > From: Mehdi AMINI [mailto:armeni67@hotmail.com] > Sent: Saturday, September 01, 2007 11:14 AM > To: Frank > Cc: xen-users@lists.xensource.com > Subject: Re: [Xen-users] dom0 without pae does not boot > > > > sorry, thats the kernel (vmlinuz-2.6.18-5-xen-686) but even > there is no > > hint for pae support.
