Dear all, I am successfully running Dragonfly as Xen 4.2.1 HVM guest for about 8 weeks now.
Successfully with a small hitch: On my Bulldozer FX-8150 system, if I give the system more than 2 VCPUs on bootup programs fail with SIGFPE (Signal 8). I have not looked into this any further, it might be a XEN issue or a Dragonfly issue. For reference, FreeBSD works fine with 4 VCPUs. I have started importing the FreeBSD xenpci drivers to get block and network devices without the additional layer of indirection hoping to increase performance a bit. PCI passthrough works brilliantly which means that I can probably a lot more efficiently work on the XHCI issues now. Cheers, Markus
