"xm info" tells you what guest types are supported.

To me, it looks like you are running a 64bit hypervisor and you try to launch
a paravirtualized FreeBSD 32bit DomU which has no PAE support.

Hi,

I'm having right now the exact same problem and exactly the same error.

My Dom0 is 64bit and I got the freebsd kernel from
http://www.fsmware.com/xenofreebsd/7.0/download/

Do you know if such a kernel is available for 32bit with PAE support ? :))

Kind regards,

Error that we are getting is "guest type xen-3.0-x86_32 not supported by
xen kernel"


If you have noticed above in the output of xm info
xen_caps               : xen-3.0-x86_32p
Does this "p" in xen-3.0-x86_32p stands for PAE ?

Should there be an explicit mention of xen-3.0-x86_32 in xen_caps ?
If yes , what determines the type of supported guests ?


Thanks,
Sanket

Yes.

You are running a 32-bit PAE Xen, which means that paravirtualised guests must 
be 32-bit PAE also.

As far as I know the *BSD ports only run on non-PAE Xen (at the moment), which 
was the default Xen build when those ports were done.

If you build a non-PAE Xen then you may have some luck running these guests.  
You can build non-PAE Linuxes to run on there too.  But you won't be able to 
run PAE guests of either PV or HVM type anymore.

Cheers,
Mark
