Folks, It would be good if you could give 2.0-testing a try out as we''re close to releasing it as 2.0.4. The main differences since 2.0.3: * Disabling the debugging that was accidentaly enabled in 2.0.2 that caused a drastic performance slow down * Move contents of /var/xen/ to /var/lib/xen as per LSB-FHS * fix network scripts not to be confused by ipv6 * misc bug fixes (e.g. to VM restore code, confusion with >4GB mem) Thanks, Ian ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.

Am I mistaken, or didn''t this used to build, even if you don''t have latex and such things that are needed to build the documentation?

Yes, indeed it did. I actually have now fixed it again as part of my re-sanitisation of the build system earlier today. I hope the build system will now be left alone. ;-) Let me know if you have the same problem even with the latest patch. -- Keir> Am I mistaken, or didn''t this used to build, even if you don''t have > latex and such things that are needed to build the documentation?

The previous build failure when latex not installed seems to have been fixed. However the patch from yesterday to create symlinks to the kernels in /boot is circumvented now that the files aren''t copied from dist/install/* as before. -install-kernels: - cp -a $(DESTDIR)/boot/* /boot/ - cp -a $(DESTDIR)/lib/modules/* /lib/modules/ - cp -dR $(DESTDIR)/boot/*$(LINUX_VER)* $(prefix)/boot/ - cp -dR $(DESTDIR)/lib/modules/* $(prefix)/lib/modules/ I can easily work around this by doing make dist and calling install.sh manually, but if anyone wanted the symlinks to be created when doing a make install, that won''t happen anymore. -- Thanks, Paul Larson plars@linuxtestproject.org http://www.linuxtestproject.org
What changeset should we be up to? I''m currently running 1.1666 which
you committed yesterday evening.
Frustrated that xm save for freebsd would give me:
(XEN) DOM0: (file=memory.c, line=425) Non-privileged attempt to map I/O
space 00000000
I tried ''xm save 0 foo'' - which I''m not sure should
be allowed - and
saw the following:

Why does xen think that an unprivileged guest has a reference to address
0 with the valid bit set?

It is a list of the page frames that make up the guest''s p2m table. If you haven''t init''ed it then the xm_save tool will probably try to map NULL and hence the error (Xen has low 1MB of memory marked as being an I/O page).> I tried ''xm save 0 foo'' - which I''m not sure should be allowed - and > saw the following:There should be a safety catch on this.

I assumed it was looking at the page tables themselves (which shouldn''t be a problem because xen shouldn''t allow it in the first place.> There should be a safety catch on this. DOM0 is definitely not > saveable!I would think not - but it doesn''t appear to realize that ;-). ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
