I didn't do any tests in general. I used for a while FreeBSD HVM (and other os guests...) under xen-3.2.1. There I got problems that VM's react very slowly under ZFS/UFS I/O stress (tar of logs, etc...) till I need to reboot the guest. It was under FreeBSD 7.2 with ZFS beta but 8.0 didn't worked with that xen/kernel. The last weeks I tried Xen 4.0.0 but tap:aio and tap:tapdisk:aio cause complete host kernel crashes under I/O stress (dd if /dev/zero...). With Xen-4.0.1-rc3-pre I haven't these problems, FreeBSD 8 is working (so booting works ;) and states/times seems a lot more healthier. Softs: Webserver with a top 5000 (alexa) site (high db access - cached, some I/O because of downloads), high threaded game server (for wc3), mail server and other webservers/stuff...
