Subject: [IA64]We have successfully booted dom0/domU/domVTI (xen/ia64) on FC5
Hi, all,
After some hard debug and work around, now we've got xen/ia64
dom0/domU/domVTI both up on FC5-IA64. Attached is the snapshot.
We still use python2.4.2 contained in FC5 for test.
We need following changes to make things happen:
- xen-tools is not built and integrated into the RPM package. Typically
we know there're 3 major directories on xen-ia64-unstable.hg: xen,linux-sparse
and tools. All three need to be kept consistence with each other. However
current fedora-kernel-ia64 only incorporates former two and tools is totally
missed. We tried to build the tools individually from xen-ia64-unstable under
same Rev (10150), and then install to target box manually.
- The configuration files for dom0/domU seems a big difference compared
to xen-ia64-unstable.hg. (Why?) Currently the ext3 is compiled as module,
however initrd doesn't work for domU even when we add "ramdisk=" in config
file. So we change ext3 to be kernel built-in, and then domU can boot up
immediately.
* Xen-ia64-unstable.hg doesn't have IDE devices configured for
domU, however fedora-kernel-ia64 does, which wastes much time for probe. If the
configuration file can be kept consistence with xen-ia64-unstable.hg, above
issues are gone.
After above 2 changes, both domU and domVTI can be boot successfully.
Following are other tricky issues we've observed:
- brctl package is not integrated into FC5 and so vnif is not available
now. People need to install brctl manually and we'll try network later. Is it
possible to add dependency check upon brctl in spec file?
- When installing xen0 rpm package, it depends on xen rpm package.
However we didn't find the xen rpm package, and had to install with "nodeps".
Actually xen image has been included in xen0 rpm package.
- Is it possible to use same configuration file for xen0/xenU just like
current xen-ia64-unstable.hg? Or at least give a configuration option to user
in spec.
- Even everything works now, we kept seeing some boring call trace from
BUG in mm/slab.c:2818, especially when vncserver is started. Actually even dom0
itself will encounter such warning infrequently before xend start.
Cheers!
