I can't reproduce this. Please check two things:
1. In block.c, the first two lines of the bdrv_cancel_nonblock_io
function should read:
if( bs-nbst.booted
bs-nbst.state != STATE_IDLE ) {
There was a bugfix here, in the most recent version of the patch, and if

I guess not, since I suppose as soon as you really knew you would be in
a position to kill the fly with a fly swatter rather than running over
it with your car :-).
Not a criticism just a nudge... this
OK, maybe robust should read slightly less flimsy :)
It'd be nice if these use cases worked, under user-mode networking:
1. The user disables and re-enables a network interface in windows.
Instead of hanging, it should come back up. (Does anyone else have this
issue?)
2. The host's DNS
After I hibernate my x86 linux host machine (using the swsusp2
package) and resume, QEMU and guest hang. That is odd, because
hibernation is transparent to all other user programs.
Has anyone else noticed this? If so please try the patch.
You know QEMU is doing something weird, for it to be
The most common use case for the '-smb' option may be '-smb $HOME'.
There is a problem with this case:
Windows attempts to connect as user nobody. Smbd allows the connection
-- unfortunately, it also maps the nobody accesses to the host's
nobody account, so all write accesses fail.
How are

Whoops. I had the mistaken belief that Qemu already used pthreads.
So, the makefiles and configure script need to handle pthreads somehow
(especially on windows.) Pthreads-w32 is refusing to 'make install'

I had to download and install Win2k SP4, then Win2k SP4 Hotfixes, and
also an IE6 upgrade, before windows update ran.
Are you running with a tun/tap device, or -user-net ? I'm still unable
to get windowsupdate to work. Getting it to work in vmware seems to work
on the first try.

Non-blocking disk IO now works for any type of disk image, not just
raw format. There is no longer any format-specific code in the patch:

You might want this patch if:
* you run a multitasking guest OS,
* you access a disk
Magnus,
I don't think the Windows 2000 install hack will ever be obsolete.
The installer assumes that a hard disk will take nonzero time to read
some data. QEMU always services a read in zero-guest-time. (With the
nonblocking IO patch, zero-guest-time reads still occur, when the

Why not use aio for this instead, seems like a better fit than spawning

Why is there a posix async IO 'standard', but a different linux AIO standard?
Linux has a Posix AIO library that sits on top of linux's native AIO:

It's pretty new, version 0.6. We might not want qemu to depend on it,
because most distros probably

Here's a patch which allows guest CPU cycles to run concurrent with IO
syscalls:

It's actually two patches -- a patch which enables DMA support (the same
one posted here a few days ago) and a second patch which
