I think that some of those problems might be issues of the Intel HAXM driver, so I suggest to report them at https://github.com/intel/haxm/issues. As stated on https://qemu.weilnetz.de/FAQ, I consider HAXM support as experimental and suggest to try WHPX which is also experimental, but seems to have less limitations and run more stable. -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1846392 Title: VCPU shutdown request with HAX Status in QEMU: New 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 usin= g QEMU. It is likely broken and doesn't boot at all. [Stuck, etc.]: I had given that image almost 2h during which the circle o= f dots continued to spin. I don't know if it or QEMU did anything of intere= st 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 distr= ibution, pretty barren by default. I've generally opened Apps there, the pa= ckage 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 tr= y to execute exotic CPU instructions in weird combinations to do a proper t= est.)
