some operation quesions #7
Comments
(please refer to the setup guide for question 1and 2)
This was cuased that you didn't have focus on the qemu window before switching foreground_os to DomU - you need a shell to echo, right? This is a bit tricky, to work around this issue, people are using remote access to Dom0 for development. Either VNC or X11 forwarding is quite good for that. |
Thank you! WIN7-VM works well now. menuentry 'Xen-VGT 3.17.0-rc4' --class ubuntu --class gnu-linux --class gnu --class os{ |
anything suspicious in dmesg or xl dmesg? |
here is some suspicious messages in xl dmesg, I'm not sure which is matter. (XEN) HVM17: You might have to change the root device (XEN) HVM17: ACPI: Early table checksum verification disabled (XEN) HVM17: AGP: Checking aperture...

I failed to find any issue in the log. Please make sure your display is not in power-saving state; and if possible, you can try to get the serial outputs of guest OS. |
I can boot when I set vgt=0 in the .hvm file, but the color of desktop is abnormal. It goes to fullscreen-black when I boot with vgt=1. Serial outputs of guest OS is as below:(XEN) Xen version 4.3.1 (root@) (gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3) debug=n Fri Jan 9 09:21:49 CST 2015 (XEN) Enable vGT for domain 4 |
