[RFC] Using linux-2.6.tip-xen on IA64
by Akio Takebe 21 Jul '06

21 Jul '06

Hi, all We can success booting domU with linux-2.6.tip-xen. (This is FedoraCore work.) The build step is the below. I think the step is almost same as Aron's step. (http://free.linux.hp.com/~agriffis/fedora-kernel-ia64/.) We used linux-2.6.tip-xen.hg(cset #30476) and xen-unstable.hg(cset #10474). 1. hg clone http://xenbits.xensource.com/ext/linux-2.6.tip-xen.hg 2. copy xen/include/asm-ia64/asm-xsi-offsets.h from xen-ia64-unstable.hg to linux-2.6.tip-xen.hg/include/asm-ia64/xen/ 3. copy .config from xen-ia64-unstable.hg/buildconfigs/linux-defconfig_xen_ia64 to linux-2.6.tip-xen/.config 4. make oldconfig (All answers are default) 5. copy linux-2.6.tip-xen.hg/arch/ia64/kernel/gate.S from linux-2.6.16.13.tar.bz2 6. cd linux-2.6.tip-xen.hg make & copy vmlinuz & mkinitrd 7. build xen-unstable.hg (cset #10474) hg clone xen-unstable.hg xen-unstable.hg-match-linux-2.6.tip cd xen-unstable.hg-match-linux.2.6.tip hg up -C 10474 make 8. copy xen.gz to under /boot/efi/ 9. make install-tools But I found some problem. Please comments. A. We cannot compile the latest linux-2.6.tip-xen(#32966). Is fixing linux-2.6.tip-xen fc6's or xen-ia64's contribution? Or is anyone already working for that? B. linux-2.6.tip-xen don't have arch/ia64/kernel/gate.S. Why? Best Regards, Akio Takebe

Virtual Machine Manager 0.1.5 release
by Daniel P. Berrange 20 Jul '06

20 Jul '06

I've just pushed out another snapshot of the Virtual Machine Manager GUI application for managing Xen machines via libvirt. A summary of the changes in this 0.1.5 release[1]: * Integration with GNOME keyring for the VNC console to avoid need to remember passwords when accessing the guest domain's console * Use cairo to render a '50% alpha gray wash' over the screenshot to give appearance of a 'dimmed' display when paused. Also render the word 'paused' in big letters. * Initial cut of code for saving & restoring domain snapshots to disk * Added icons for buttons which were missing graphics * Miscellaneous RPM spec file fixes to comply with rpmlint * Update status icons to match those in the gnome-applet-vm * Added domain ID and # VCPUs to summary view * Misc bug fixes The next priority target for development is some UI for creating new VM instances (a GUI equivalent of xenguest-install.py script shipping with current Fedora Xen packages) and implenenting the UI for editing domain configuration / hardware. In addition there is now a more permanent home for the application's web pages: http://virt-manager.et.redhat.com/index.html And the Mercurial repository is now published for anonymous read-only access at: http://hg.et.redhat.com/virt/applications/virt-manager--devel Patches are welcome either as traditional unified diffs, or as mercurial changeset bundles - see the following page for details on exporting bundles using hg: http://virt-manager.et.redhat.com/scmrepo.html Regards, Dan. [1] There was a 0.1.4 but it had a fatal flaw in it breaking the console -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=|

FC5-- building xen-unstable to get xenoprof built...-- get compilation errors
by shobha ranganathan 20 Jul '06

20 Jul '06

I am trying to get xenoprof built in Xen environment. I downloaded the xen-unstable-src.tar in FC5 x86 system where I have both xen0 and xenU kernel built and up in running. I did the following cd xen-unstable Now I need to invoke "make menuconfig" to setup options for Profiling in kernel and then do "make world" and "make install". I do not find linux-2.6.x.x-xen directory to run "make menuconfig".. Also when I do the steps cd xen-unstable make KERNELS=linux-2.6-xen world make[3]: Entering directory `/root/xen-unstable/xen/arch/x86' gcc -Wdeclaration-after-statement -nostdinc -fno-builtin -fno-common -fno-strict-aliasing -iwithprefix include -Wall -Werror -Wno-pointer-arith -pipe -I/root/xen-unstable/xen/include -I/root/xen-unstable/xen/include/asm-x86/mach-generic -I/root/xen-unstable/xen/include/asm-x86/mach-default -O3 -fomit-frame-pointer -msoft-float -m32 -march=i686 -DNDEBUG -S -o asm-offsets.s x86_32/asm-offsets.c cc1: warnings being treated as errors In file included from /root/xen-unstable/xen/include/asm/mpspec.h:5, from /root/xen-unstable/xen/include/asm/smp.h:18, from /root/xen-unstable/xen/include/xen/smp.h:13, from /root/xen-unstable/xen/include/xen/sched.h:8, from x86_32/asm-offsets.c:9: /root/xen-unstable/xen/include/asm/mpspec_def.h:78: warning: âpackedâ attribute ignored for field of type âunsigned char[5u]â make[3]: *** [asm-offsets.s] Error 1 make[3]: Leaving directory `/root/xen-unstable/xen/arch/x86' make[2]: *** [/root/xen-unstable/xen/xen] Error 2 make[2]: Leaving directory `/root/xen-unstable/xen' make[1]: *** [install-xen] Error 2 make[1]: Leaving directory `/root/xen-unstable' make: *** [world] Erro What am I doing wrong here ? thanks Shobha --------------------------------- Yahoo!

I think you want to add some kernel booting parameter to a XenU domain. You can try to add "extra=booting_parameter" in XenU configuration file.
