How can I run 3.x dom0 w/o PAE?

How can I run 3.x dom0 w/o PAE?

Hi Jeremy,

I'm now working in a Xen-based project where some drivers in the Dom0 kernel (based on Linux 3.0) refuse to work with PAE. Do you know if it is possible to run 3.x kernel as non-PAE dom0 on Xen (any version is ok)? If so, how can I make it work? Many thanks in advance!

Best Regards
Junjie Mao

No, we removed non-PAE 32-bit operation a long time ago, and its not
coming back. What drivers don't work with PAE enabled? PAE has been more
or less essential for a long time. You should either adapt the drivers
to deal with PAE (presumably, highmem) or use a 64-bit dom0.
