The following two commits are needed for Xen: f8e8fd56bd7d5675e8331b4ec74bae76c9dbf24e x86/HVM: fix initialization of wallclock time for PVHVM on migration 32c864a35ece2c24a336d183869a546798a4b241 x86/vtsc: update vcpu_time in hvm_set_guest_time With this branch I've been able to successfully local migrate a busy VM 400 times consecutively. As usual, the branch can be found here: http://xenbits.xen.org/gitweb/?p=people/royger/freebsd.git;a=shortlog;h=refs/heads/pvhvm_v16
