Hi all,
I build xen4.1 from the tarbll (with kernel 2.6.32.26 downloaded by default)
on fedora8.
After installing, I get the err msg on startup:
(XEN) Panic on CPU 0
(XEN) BUG at domain_page.c
5 seconds later, the machine reboot.
How to deal with this problem.
Thanks,
--

You need to post the full boot log, including all output from both Xen and dom0 Linux.

The err msg appears in
void *map_domain_page(unsigned long mfn)
BUG_ON(idx >= MAPCACHE_ENTRIES);
printk idx is 1024 and BUG_ON is called.
I print Xen call trace msg:

The bug exist in iommu(Intel VT-d) support code.
After I disabled the vt-d in bios, system can boot properly.

Could you build a 64-bit hypervisor instead? In all honesty, the 32-bit
build gets hardly any testing these days, and not much love.

Thank you for your reply.
We want to work in 32-bit system.
And fortunately we don't need IOMMU and passthr at the present.
There is another problem:
xend start failed
err msg is:
xen.lowlevel.xc.Error: (1, "Internal error"), 'Could not obtain handle on
privileged command interface (2 = No such file or directory)'
I find there is nothing in "/proc/xen/" but there is privcmd.o in
"bulid-linux-2.6-pvos_x86_32/drivers/xen/xenfs/"

You know you can have a 32bit dom0 kernel running on 64bit Xen hypervisor?

Usually you build them separately, maybe on different servers,
or on different VMs, or on different chroot..
ie. have a 64bit environment for building the hypervisor,
and 32bit environment to build the dom0 kernel and xen tools/userland.

Actually, all you need is a cross tool chain.

That's right. On a Debian Lenny it works out of the box, you just need
to export XEN_TARGET_ARCH=x86_64 before calling 'make xen' from.

Which linux distro do you use to build xen?
We succeed to build on fc8(32 and 64 bits), Cent OS(32 and 64 bits), 32 bit
ubuntu(it's boring to find and install many packages by manual).
We tried on fc9~fc12 but failed and we don't know the exact reason. So we
have been using fc8.

I use Debian. Mainly Lenny for development work but also some Squeeze
and Sid.

Ubuntu has a huge number of packages available via APT (using apt-get,
aptitude, synaptic, PackageKit or whatever tool is preferred/recommended
under Ubuntu these days). I'd be surprised if you needed to find and
install _many_ packages manually. Under Debian you don't, AFAIR, need
anything which isn't packaged and available via APT in the main Debian
repositories to build Xen -- I'd be surprised if Ubuntu wasn't in
broadly the same position (since it inherits large parts of Debian's
package pool).

I'm sure plenty of people on the list use Fedora and they are certainly
using things newer than fc8. For example there is an FC13 howto at

Fedora 14 works aswell. I just installed F14 testbox yesterday.
F14 also contains xen-4.0.1-6 rpms out-of-the-box.
