Sergey Bychkov a e'crit :
> Some changes made last month led to increased CPU usage by host even

> This is found for x86_64 host with qemu-system-x86_64.
> Qemu process uses about 20-50% of one CPU, as seen by htop.
> Result doesn't depend on guest OS: Knoppix and Win2k3 tested,
> It doesn't depend on details of host CPU - 2 different computers tested
> - but they are both dual-core amd64-compatible intels.
> Result doesn't depend on network, nor display configuration of guest.

This has been fixed in revision 4270.
