Hi, another issue I''m seeing with 3.0-rc2 and Xen is that there is an unexpectedly high amount of kernel reserved memory. I suspect that Linux allocates page table entries and corresponding data structures for the whole 6GB areas of the provided ''physical RAM map'' even though it has rather big unusable holes in it.

Hi! We have a problem that the dom0 very often does not boot and hangs in the hypervisor - see screenshot. The last message is: (XEN) Dom0 has maximum 16 VCPUs (afterwards xen should overwrite the memory) We are using the xen kernel from kernel.org git. Kernel is 2.6.32.24-xen with Xen 4.0.1 Hardware is HP DL380. Is this a known problem? Any hints what could be the problem and how we can

Lots of changes since v2, too much to remember or summarize. Please ignore patch 11/11, it's just for my testing. Rich.
