Hey all, Just downloaded the new Xen 4.0 and ran Make xen Make tools Make stubdom Copied the new files from dist/install Im already running pv_ops 2.6.31.6 kernel. When I boot i get (XEN) Panic on CPU 0: (XEN) IO-APIC + timer doesn''t work! I have tried booting with noapic boot option but makes no difference. The system worked fine on 3.4.2 CPU is AMD.

The KVM introspection subsystem provides a facility for applications running on the host or in a separate VM, to control the execution of other VMs (pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.), alter the page access bits in the shadow page tables (only for the hardware backed ones, eg. Intel's EPT) and receive notifications when events of interest have taken place

Greetings, I got the below dmesg and the first bad commit is commit cf39c8e5352b4fb9efedfe7e9acb566a85ed847c Merge: 3398d25 23b7eaf Author: Linus Torvalds <torvalds@linux-foundation.org> Date: Wed Sep 4 17:45:39 2013 -0700 Merge tag ''stable/for-linus-3.12-rc0-tag'' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip Pull Xen updates from Konrad

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.
