...tions can cause more skew?) If the load on other domains canNOT affect time skew on domain A, testing for time skew becomes a lot easier. (Use sched-credit instead of launching multiple domains.)

Folks, A new release candidate for 3.2.0 has just been checked into the xen-unstable tree. It''s available from staging and will be in the main tree when it has passed internal regression tests. Meanwhile, in preparation for 3.1.3, please let me know if there are any further patches from xen-unstable that should be backported into the 3.1 branch. You can pull the xen-3.1-testing.hg

Various versions of Linux under various circumstances select TSC as the primary clocksource for the kernel. This is especially true for uniprocessor kernels, but also in some cases for multiprocessor kernels. In most cases, this is because a processor bit (tsc_invariant? constant_tsc?) is passed through directly from the hardware via Xen and tested by the hvm guest and the result implies that
