Hi,
I had a problem trying to migrate domains, in trying to locate it I
noticed that saving domains doesn't work either, which I believe
explains why the receiving xfrd doesn't actually receive anything.
So here it goes...
xenone:/tmp# xm list
Name Id Mem(MB) CPU State Time(s) Console
Domain-0 0 123 0 r---- 900.6
sky 9 128 1 -b--- 32.8 9609
xenone:/tmp# xm save 9 test
Error: Error: [Failure instance: Traceback:
xen.xend.XendError.XendError, save failed

Built from source under 2.6.10, everything else seems to be working.
Tried both using raw sda and using a lvm device, neither work.
