is kernel-xen PAE ?

I noticed that with my 32 bit architecture kernel-xen, I can see my 16
Gb of ram !
does that mean that kernel-xen is PAE enabled by default ? how can I
check that ?

then, if it does manages my 16 GB, will my para-virtualized 32 bits xen
guests could have more than 4 GB each ?

Regards .

Ok, to be sure, I though I could check kernel compiled option somewhere
... but can find where ....

No I haven't tried yet for the guests, I would have prefered to be sure
first .

By the way, I supose that a clean solution would be to upgrade my 32 bit
system (domain-0) to a 64 bit one !
but apparently it is not an easy thing to do :-(

is there a simpler solution ?
