Hi all,

if I try to save and restore an image using current qemu and current 
libvirt, the load fails.  Comparing a preexisting save file and the new 
save file generated by QEMU master, I get differences in an ide block 
like this (cmp output):

67500802   0  20

The IDE section starts at 67499922 (this is where the 0x00000004 
signature is, so the error is 880 bytes inside the IDE block including 
the section headers).

I could not pinpoint any obvious culprit in the log.  Hope this helps.
