the external module (once patched) will only be able to build against 2.6.17 upwards because the in-kernel PIC/IOAPIC/LAPIC requires hrtimers and that functionality was only made public to external modules during the stabilization of 2.6.17 as seen by : http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=8d16b76421f0b3216012ee2d7819355e1cb847e5 there are obviously 3 possible fixes : 1) rewrite the in-kernel PIC/IOAPIC/LAPIC not to use hrtimers (not worthy) 2) replicate the functionality needed in the compatibility header or with the use of a helper (not that simple) 3) disable the functionality and ifdef the code for kernel < 2.6.17 (preferred) but before, I would like to ask: is 2.6.9 upwards support really needed?, the only reason why I would suspect that 2.6.9 was recommended was because of RHEL4 but there is no kvm package available for it from Red Hat or in EPEL and Full Support is due May 15, 2008 so there might not be one ever, specially considering that Red Hat is focused on RHEL 5 Host for virtualization support as can be seen by : http://www.redhat.com/rhel/virtualization/ other Linux distributions that are still under support will be affected as well (mainly because they are corporate linux focused and with longer supported timelines than community oriented distributions) but AFAIK they don't have yet a kvm package (and might never had one) : * Ubuntu Dapper 6.06.1 LTS (2.6.15) * SuSE Linux 10.1 (2.6.16) * Mandriva Corporate 4 (2.6.12) of course ALL community oriented distributions (fedora, ubuntu, gentoo) which are currently packaging kvm are ok and won't be affected by a "2.6.17 upwards" requirement. Carlo PS. shouldn't the 2.6.9 or higher requirement be in this page? http://kvm.qumranet.com/kvmwiki/Downloads ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
