Subject: [acrn-users] Problem with Using Windows as Guest VM on ACRN



   Following the instructions of the doc , but it did not show windows installation on the HDMI screen.

This is my build steps:

 My board is NUC7i5BNB, Clear linux verson is 32680, I update the hypervisor and kernel to release 2.0 with the boot menu ACRNGT Service VM.

root@clr-sata~ # uname -a

Linux clr-sata 5.4.43-PKT-200203T060100Z #3 SMP PREEMPT Tue Aug 4 10:24:36 CST 2020 x86_64 GNU/Linux

root@clr-sata~ # acrn-dm -v

DM version is: 2.0-64896ac9 (daily tag:acrn-2020w25.7-180000p), build by acrn@2020-08-04 10:38:21

I login the NUC with ths ssh on another pc as the second monitor. The first monitor is the hdmi of the NUC.

There is something wrong when I set the weston desktop.

# useradd cl_uos

# passwd cl_uos

# usermod -G wheel -a cl_uos

# systemctl enable weston@cl_uos

# systemctl start weston@cl_uos

reboot into Clear Linux OS (acrn) --the origin SOS,  the system show the desktop, like the picture1.

reboot into Tht ACRNGT Service VM --the updated  hypervisor and kernel SOS, the system show the login screen but can not input , like the picture2.

Run the in the ACRNGT Service VM,  I think the UOS is running according to the log, but the HDMI show like the picture3.

I'm not sure the set of the weston desktop and use the ssh as the second monitor.

Is there something wrong in the above steps?


my acrngt.conf is different from the instructions of the doc.  


+ initrd /EFI/org.clearlinux/freestanding-00-intel-ucode.cpio

+ initrd /EFI/org.clearlinux/freestanding-i915-firmware.cpio.xz

otherwise the ACRNGT Service can't bootup.

to reserve more free pages:

now enough free pages are reserved!


try to setup hugepage with:

really setup hugepage with:

            level 1 - lowmem 0x80000000, biosmem 0x0, highmem 0x80000000
