Can you try with a -current kernel as dom0 ?
This is what I'm testing now:
NetBSD borneo.soc.lip6.fr 9.99.17 NetBSD 9.99.17 (XEN3_DOM0) #0: Mon Nov 11 18:06:47 UTC 2019  mkrepro%mkrepro.NetBSD.org@localhost:/usr/src/sys/arch/xen/compile/XEN3_DOM0 amd64

The domU is:
NetBSD cuba.lip6.fr 8.0_STABLE NetBSD 8.0_STABLE (XEN3PAE_DOMU) #0: Sun Mar  3 11:11:18 UTC 2019  mkrepro%mkrepro.NetBSD.org@localhost:/usr/src/sys/arch/xen/compile/XEN3PAE_DOMU i386

It is Xen 4.11.2nb2, but the Xen version shouldn't matter.
