Problems with CrosVM on Windows 11 Pro (x64)

[Lonnie TC]

Hello All,

I have HAXM (v7.8.0) installed on a Windows 11 Pro (x64) along with no hyperv installed which is running:

----------------------------------------

D:\haxm\checktool-windows-1.1.0>checktool.exe
CPU vendor          *  GenuineIntel
Intel64 supported   *  Yes
VMX supported       *  Yes
VMX enabled         *  Yes
EPT supported       *  Yes
NX supported        *  Yes
NX enabled          *  Yes
Hyper-V disabled    *  Yes
OS version          *  Windows 10.0.22631
OS architecture     *  x86_64
Guest unoccupied    *  Yes. 0 guest(s)

D:\haxm\checktool-windows-1.1.0>sc query intelhaxm

SERVICE_NAME: intelhaxm
        TYPE               : 1  KERNEL_DRIVER
        STATE              : 4  RUNNING
                                (STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0

-----------------------------------------

 I have then been able to compile crosvm with Rust [rustc 1.74.0 (79e9716c9 2023-11-13)] which compiled to the crosvm.exe file.

I also compiled the baremetal example just to get a simple test that everything was working, but when I run:

---------------------------------------

.\crosvm.exe run --disable-sandbox .\example\baremetal
[2023-12-03T15:50:30.497163000+00:00 INFO  base::sys::windows::platform_timer_resolution] Successfully set timer res to 0.5ms with NtSetTimerResolution. Measured 1199us.

    exit code: -536870763 = 0xe0000095

PS D:\Crosvm\test> rustc --version
rustc 1.74.0 (79e9716c9 2023-11-13)

------------------------------------

The main problem seems to be "Cannot initialize HAXM: The system cannot find the file specified. (os error 2)" but I do not know what file it is looking for.

Also as a note, I am still a bit new to Rust.

Any thoughts on how to resolve this?

Thanks in advance and have a great day,

Lonnie

Hi Lonnie,

Try running with "--hypervisor Haxm". Without that option, crosvm tries to use an internal Google fork of HAXM.

Hi Steven,

Thanks for the reply on my crosvm post.

Looks like I had "some" success, but may not be complete:

I do see the "Hello World!" but also get an ERROR which may be coming from the baremetal code, but not sure.

---------------------------------------------------------------------

Is there a way for me to have crosvm.exe boot up a live CD/DVD to test it out that way as well since I do not have any other kernel/rootfs images at the moment which is why I tried the baremetal approach.

I think that if I can boot up a live CD?DVD then that will be a very good test as well.

Best
Lonnie

Hi Lonnie,

Sorry, I'm not familiar with booting a live CD. Maybe someone else on the list has experience.

If you want to try building a guest Linux kernel and rootfs, the crosvm docs have instructions: https://crosvm.dev/book/running_crosvm/custom_kernel_rootfs.html
