I don't think this is an issue with out the kernel was compiled. In fact, all of the ways mentioned will build the pvops kernel properly. I have run into a similar problem with the kernel trying to add/remove/modify ioapic stuff as well (and have tried to compile the kernel in every possible way, but still get the same problem). I have a feeling it is an issue with the pvops kernel ioapic code and have spent some time trying to track it down, but haven't found anything yet. The XCI 2.6.27 kernel works, though, so if you're just looking for a more modern kernel than 2.6.18, then I suggest using that. Hopefully this issue can be resolved soon, though. I would prefer to develop against the pvops kernel now that it's been selected as the xen-unstable default kernel.

Did anyone meet this issue? Is there any difference on build and installation between pvops dom0 and 2.6.18 dom0? Following is my instructions, pls correct me if something is wrong. Appreciate in advance. My build and installation instructions: - cd xen-unstable.hg - make world (linux-2.6-pvops.git will be cloned) - make install My grub entry: title Xen - pvops root (hd0,2) kernel /boot/xen.gz dom0_mem=512m module /boot/vmlinuz-2.6-30.rc3-tip ro root=/dev/sda3 console=tty0 console=ttyS0 I also tried build pvops dom0 manually as follows, but it doesn't help. - cd linux-2.6-pvops.git - make - make modules_install - make installI am not quite sure if that is the correct way to recompile kernel, as sometimes I have some problems with Dom0 booting after that. I usually recompile Dom0 kernel this way: (from the root directory) # make linux-2.6-xen-config (to configure kernel options) # make linux-2.6-xen-build # make linux-2.6-xen-install Then dont forget to "mkinitramfs", of course Thanks, J _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
