[Qemu-devel] save/restore broken?

[Paolo Bonzini <bonzini@gnu.org>]

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
67500803  20   0
67500808   0   1
67500809   1   0
67500812   0  10
67500813  10  47
67500814  47 374
67500815 374 232
67500816 232   0
67500821   0 360
67500822 360 120
67500823 120   0
67500828   0  20
67500830  20   0
67500832   0   1
67500833   0 300
67500834   1 205
67500835 300   0
67500836 205   0

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.
