if you're running pure pv domUs (with no real hardware support), this should be completely transparent for the hypervisor i'm running x86_64 xen-sources-2.6.34-r5 on both dom0 and domUs on Xen 4.1.2 (still using xend/xm interface): everything works stable enough. i have already switched to new hardware, upgraded xen, kernel configuration and versions whilst domU configs did not change for years the only significant improvement of recent xen (for small configurations: i dont have experience with more than 2 cpu sockets systems) is an enhanced support of vt-d (iommu); turn it off and re-try - there are many incompatibilities there probably causing xen to hang victor
