James, if you can find some free time, could you please explain us how this vscsi thing works and how to enable it? Would it also gain us some performance, or is for serving other purpose?

Since 0.9.2 I have fixed one memory alloc/free error, but I'm not
confident that it's the error you are seeing. The strange thing is, that
error should have meant that xennet would crash every single time it
loaded, but obviously it wasn't. It might explain why some people got
BSoD's on loading xennet sometimes though...

I can enable and disable my xennet network adapter without problems at
the current hg version (eg post 0.9.2), but I don't remember trying
previously.

I've just gotten xenscsi working properly (allows scsi passthrough to
windows, needs the vscsi patches posted to the list ages ago) and I'm
testing a Symantec Backup Exec 'baremetal' restore in a windows DomU...
so far so good. I'll upload 0.9.3 in the next few days assuming nothing
breaks.

James
