Re: [Xen-users] Serious performance problems - is Xen not ready for production use?




Hi Mark,

thanks for the reply!

First check: Can you verify that IDE DMA is working on your system? If not, you'll probably need to build a new kernel with the appropriate drivers.

Yes, DMA is fine!

If that doesn't help:

I'll come back to this and will some more test this afternoon. I will post here...

The memory ballooning needs to be fixed. I can't remember what release the reported breakage was in - it's probably an easy fix either way. The break probably went unnoticed because people usually don't balloon domains above their initial allocation.

That's great news! Not that it's broken but that it's a known problem ;) I can live easily with the current and wait for a fix in the future...

Regards,
  Patrick
