+VCPU shutdown request with HAX
+
+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 notes:
+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).
+
+
+First, those that QEMU seemed to handle well:
+Q64 -machine q35 -accel hax
+Q64 -machine q35 -cdrom \!S\Win10-1709-PE_Custom.iso
+Q64 -machine q35 -cdrom \!S\Win10-1709-PE_Custom.iso -m 4096 [Stuck, etc.]

+Q64 -cdrom \!S\Win10_1709_German_x32.iso -m 512 -cpu coreduo
+
+
+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.
+Q64 -machine q35,accel=hax -cpu max  {many}
+Q64 -machine q35,accel=hax -cdrom \!S\Win10-1709-PE_Custom.iso

+
+
+(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.
