I got some offlist hints and now I believe:
this is not a recent regression
a pv dom0 with multiple cpus keeps time badly
a pv or pvshim domU with multiple cpus keeps time badly
I have changed to vcpu=1 for both domUs and added to my dom0 boot line:
dom0_max_vcpus=1
and now things seem much better. But, a PV domU netbsd-9 amd64 guest
with 2 cpus was mostly ok before.
