The patch in r5531 which replaced a bunch of strncpy with pstrcpy causes
the x509 credentials from the -vnc parameter to be one character shorter
than entered meaning that there is currently no way to enter x509
certificates...

After going through the debug log and scratching my head for quite some
time. I found the following:
The problem was with this block move:
lsi_scsi: SCRIPTS dsp=0fae8e50 opcode 01000028 arg 00f63c40
lsi_scsi: DMA addr=0x00f63c40 len=36
The number of bytes to be transferred (len) should be 40 which corresponds
to the block transfer of length 0x28 (from opcode 01000028). Instead we
have a length of 36 (0x24). The code responsible for this is (in
'lsi_do_dma'):
if (count > s->current_dma_len)
count = s->current_dma_len;
Basically we're overwriting the length 40 with the value 36 which I
think we just left over in that variable from an earlier transfer. In my
patch below I initialize s->current_dma_len to s->dbc before we begin
the DMA transfer during Data In phase.
The attached patch gets Openserver 5.0.5 past the hardware detection
(and it lists the hard drive to boot, woohoo). It appears to stop a
little while later (doesn't seem SCSI related), but it's been so long since
I've booted Openserver I'm not sure what's supposted to happen after the HW
detection using the boot/root disks.
Props go to Craig Ringer for the initial post and the code that he posted
some of which is in this patch.

- IOC bitfields sizes are incorrectly set
This patch corrects the ioctl TCGETS done by isatty function call

Unfortunately, -linux-user doesn't use osdep as it replaces some of those
functions with specific ones. The code #ifdef code in exec.c needs to
remain in place so instead of introducing a qemu_getpagesize() let's just
use getpagesize() in the non-Windows implementation of qemu_vmalloc.

This switches the tcp, telnet and unix socket support for character
devices (serial/parallel, ...) to the new socket helpers. Thereby they
gain IPv6 support and also get ability to search for a free tcp port.
Syntax is the same as for vnc, using a to= option, like this:
-serial tcp:localhost:5000,to=5099,server
This will check the 5000 -> 5099 port range (inclusive) for a free tcp
port. Likewise you can get auto-allocated unix sockets by specifying an
empty path:
-serial unix:,server
qemu will create a randomly named socket in $TMPDIR then.
tcp also got new "ipv4" and "ipv6" options to make qemu try only the
specified internet protocol version.
You can use the "info chardev" command added by the first patch in this
series to figure the tcp port / unix socket actually allocated.

This patch switches the vnc code ofer to the new socket helper
functions.
It adds support IPv6 support and for automatically allocating an unused
vnc display port. The latter is handled ising a to= option, specifying
the upper limit for the display number to try. Scanning is started at
the display number given in the display specification, i.e. this command
line:
-vnc localhost:7,to=11
will try displays 7 to 11 (inclusive).
There are also new "ipv4" and "ipv6" options to make qemu try only
the specified internet protocol version.
The display actually allocated can be queried using the "info vnc"
monitor command.

New features of this code are (a) support for searching for a free

KVM's live migration support included support for exec: URLs, allowing system
state to be written or received via an arbitrary popen()ed subprocess. This
provides a convenient way to pipe state through a compression algorithm or an
arbitrary network transport on its way to its destination, and a convenient way
to write state to disk; libvirt's qemu driver currently uses migration to exec:
targets for this latter purpose.
This version of the patch refactors now-common code from migrate-tcp.c into
migrate.c.

(between 5 and 8), so it is worth converting them to TCG.

The cmpbge instruction should compare all 8 bytes of one 64-bit value with
