This one is from dom0, although domU is identical. Let me know if a vmlinuz, vmlinuz-syms, and/or System.map files are needed. I''m running a couple of hundred 3.0 domains and it is now happening much more often.

[Xen-devel] Xen and HyperThreading/Dual Core Issues
Dear Community, Me and some folks are about to start a research project on HyperThreading/Dual Core issues on Xen. Our main goal would be to answer the following question: - How to improve the current Xen support to HT and Dual Core CPUs? The immediate thought was to investigate what are the vCPU-to-CPU mappings that make sense (e.g. 1-N, N-N, N-1) and come up with a strategy for dynamic vCPU-CPU (re)association according to the perceived resource utilization of each domain. I searched through the xen-devel list archive and part of the source code (unstable). If I correctly understood, it seems that xen-3.0 already provides a good support to HT and Dual Core including vCPU-CPU migration and multiple vCPUs per domain. So, is there any planed road map for future improvements with respect these issues defined yet? what is the status of the current efforts? Thanks in advance, Best Regards, Eli _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
