I can't understand why clock in guest OS (Windows 2003) goes very slow.
Are you sure the rtc freq has been made to 1024?

Clock is slower than in host, but Windows Time server could correct this, if

Hi,
this patch allows to mount qemu disk images on the host.
It is based on the Network Block Device protocol and allows qemu-img to
become an NBD server (Yes, Anthony, userspace block device is the right
way to do that... :-P ).
Once you've applied the attached patch to Qemu and build the

This patch has an awful lot of #ifdef __linux__ in it. But
qemu-img.c has copies of qemu_malloc et al, which are already provided
in osdep.c. The attached patch removes these from qemu-img.c and
adds osdep.o to BLOCK_OBJS.
(It wants to be in BLOCK_OBJS rather than just in qemu-img to support
my next patch.)
