Hello all,

I am a newbie of QEMU and wondering to know the meaning of:

Hello all,
I am wondering to know whether QEMU could run "the same" twice. ie. the same
of execution trace.
I read the user manual and find options like: "-clock dynticks -rtc
base=2006-06-17T16:01:21,clock=vm -icount 1".
Would QEMU run "the same" with these options??
PS. I also found the functi

I have written my own TCG code generator (translate TCG to i386). It works

Hello Kevin, Stefan and all
There is a sentence "The maximum size of a dynamic hard disk is 2040 GB.
The actual size is restricted by the underlying disk hardware protocol. For
example,
ATA hard disks have a 127-GB limit" in VHD specification. This limitation
infected the
algorithm of block/vpc.c:
right??
Thanks a lot

Hell all,
I have take a look of block/vpc.c and meet a question in vpc_create(). At
the line
550, the code is:
total_sectors = options->value.n / 512;
I am wondering whether the size between total_sectors * 512
and options->value.n
would be discard.
Thanks
Mitnick
This my first time to submit patch, please tell me if I have something
wrong!
Create scratch/ on first run.

Would you mind to tell me the project containing four topics above is
suitable for GSoC of size and skill level??
And would anyone is interested in this project and being my mentor??

Hello all,
I have used QEMU to assist me developing embedded system for 3 years. And I
want to contribute to QEMU and participate Google Summer of Code this year.
I have port binutils so I have some experienced with binary format. I
noticed that there is no VHD support in qemu-img. A Virtual Hard
