<div>Follow the use's guide, I test a sheepdog vdi (run windows

<div>1. qemu1.5 installed, when running qemu-system-x86_64 with

qemu1.4, an error appears "invalid write to memory region kvm-pic", but
client OS running normally and quickly.</div>

<div>2. In the client system(windows2003 server), download or copy files
up to 100M bytes, the vdi seems halt and recover after finishing the
download task, it cost quite a long time. why?</div></div></blockquote><div style="">
Do you mean VM is halted? How do you copy the files? Could you please describe more? And what is in sheep.log?<br> *
Halt is not very exactly. The client OS lose reactions except mouse.
When copy files to any other fold or download using IE, at first the
speed is fast until hundreds mega bytes(concerned with cache?). At the
same time, I found the file number of objects fold increase. When this
happen,Nothing is added to sheep.log. Maybe just the writing speed's
influence?<br></div><div style=""> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

I use vir-manager and modifid the xml file. It seems using qemu-kvm as
emulator. What are the differences between qemu and qemu-kvm? Does
