Hi Booting my Xen Dom0 on Debian Etch (Kernel is the prebuild one from bits.xensource.com), I found that only one cpu core (of two: dual core) is recognized by the (dom0-)Kernel. Googling this issue, I found on xen-devel-list that xen kernel is named smp but isn''t really doing so. Is there any (prebuild) kernel that I can use for smp? Thanks Gregor Reich _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

You should be able to add more CPUs to it (I''m not sure how, although maybe vcpu-add would work). domUs should also be able to be SMP perfectly happily, if they have support compiled in. The reference you found on the xen-devel list is probably out of date now: it used to be that Xen supported multiprocessor systems, but guests could only be uniprocessor. This is no longer the case, since Xen 3.0, so you shouldn''t have to worry about it. Hope this helps you get up and running! Cheers, Mark -- Dave: Just a question. What use is a unicyle with no seat?
