Title:
VCPU shutdown request with HAX
Status in QEMU:
Expired
Bug description:
In most scenarios when turning on HAX, QEMU will exit, printing "VCPU
shutdown request" to the console.
This is on Windows 8.1 with Intel HAXM 7.5.2.
QEMU's -version prints v4.1.0-11789-g013a2ecf4f-dirty .
I've used an installer from qemu.weilnetz.de.
The host CPU is an IvyBridge i5 (mobile).
Some miscellaneous notes (you can skip them first):
Win10-1709-PE_Custom.iso is a custom WinPE image I had meant to test using
QEMU. It is likely broken and doesn't boot at all.
[Stuck, etc.]: I had given that image almost 2h during which the circle of
dots continued to spin. I don't know if it or QEMU did anything of interest at
all during that period, but this might indicate long-term stability, sort of.
Win10_1709_German_x32.iso: Stock Win10 1709 32bit ISO I got off a German tech
website. I've waited for the install screen to appear.
TinyCore_10-1.iso: TinyCore by Core Project. A 18MB graphical Linux
distribution, pretty barren by default. I've generally opened Apps there, the
package manager, then shut it down again.
On the one marked [Fx stable], I've gotten Firefox 60.8.0 ESR and visited a
couple of websites. (I don't know of any available program that would try to
execute exotic CPU instructions in weird combinations to do a proper test.)
Q64 is .\qemu-system-x86_64.exe , substituted for readability (shorter lines).
Invocations that QEMU seemed to handle well (without the headline error):

Then, those that made it print "VCPU shutdown request" repeatedly and quit,
immediately or after a couple of seconds at most, except where noted. I put an
indication of the number of messages into curly braces.

(I have rewritten a couple of commandlines to make them more uniform
(changing the placement of parameters and using '-accel hax' instead
of '-machine ...,accel=hax').)
[1]: WinPE boot error, not enough RAM.
[2]: Will cause a kernel BUG: "... \ login[892]: root login on 'tty1' \ BUG:
unable to handle kernel paging request at 00010ffa \ ...". See attached file.
[3]: Stuck after "Booting the kernel.", cursor blinks.
[4]: Stuck at blinking console prompt, no input possible.
[5]: According to the printout, TCG doesn't support a bunch of those
processor's features that have been requested.
PS: There should be some note highlighting that there is a strict limit on
line length (or at least that's what it looks like). I can shorten the file
names further to enhance skimmability ... :/
Also, let me know if you need anything else.
