Hi, I am trying to correlating performance issue in guest VM with the scheduling trace from Xentrace. User-mode application in guest VM periodically dump APIC ID and RDTSC into trace. I also start Xentrace in Dom0 during the same period. However, I notice that range of TSC values report both trace is completely disjointed. TSC values from Xentrace is always greater than what guest VM see, even

Hey, I''m experiencing strange problem: non-deterministic PV domain hang, only on some machines (with fast SSD drive). I''ve tried xen-4.1.0 and xen-4.1.1 with many kernels different kernels: VM: - 2.6.38.3 xenlinux based on SUSE package - vanilla 3.0.3 - vanilla 3.1 rc2 dom0: - 2.6.38.3 xenlinux based on SUSE package - vanilla 3.1 rc2 Result always the same: sometimes VM

It seems that this knob is expoerted from the hypervisor as a raw integer (no symbolic names) documented in xen/include/asm-x86. Propagating that all the way to the

The following series flushes my documentation queue and replaces previous postings of those patches. The main difference is that the xl cfg file is now formatted using POD instead of markdown and presented as a manpage. I have setup a cron job to build docs/html and publish it at http://xenbits.xen.org/docs/unstable/ (it''s a bit bare right now). The motivation for some of these patches
