Have you allocated the whole "disk" file before creating the

Which I reckon creates a sparse file. How do you suggest I do it instead?
I can run an iozone test in DomU without any problem (which certainly is
much more disk IO intensive than scp). Even using LVM, MD and other setups
in DomU does not appear to cause problems.
Hmmmm. So how're you creating the files in Dom) to be used by the DomUs?
My HW/SW setup is the same as yours, but I am running everything
on 64-bit... it may behave differently on 32-bit.
Everything? I thought running the Dom0 and certainly the DomUs on 64-bit
was the subject of my last email subject (i.e. that it wasn't even
Technology Preview quality)?
