Hello Everyone I am trying to boot a VM using Ubuntu-15.04 and get a GUI view of the OS.
My setup is as follows: * I boot a linux-4.1 KVM hypervisor using Ubuntu 15.04 on a headless embedded board (no VGA card) * I start a VNC server on the board and connect from a desktop to the VNC session. I get a xubuntu desktop then * On the Ubuntu desktop I open an Xterm window and try to boot a guest with a copy of the same Ubuntu 15.04 file system. A few things happen: * Qemu open directly to the QEMU console. When I switch to the guest (alt + ctl + shift + 2) I get the console boot of the guest. * The quest reaches console login but during the OS service startup phase I notice that lightdm service fails to start. It starts and stops for 4-5 times before it gives up. * If I run "startx" in the guests console I get an Error "(EE) no screens found" >From what I can gather it looks like QEMU is not generating a screen for the >guest to work with. I understood that QEMU uses SDL to start a screen for the >guest but I suspect that doesn't happen for some reason. Also the fact that >the Qemu window start in the console instead of SDL view looks strange. I am using qemu-system-aarch64 version 2.2.0 installed from Ubuntu repositories. Maybe this image was built without SDL support ? My VM boot command line is: qemu-system-aarch64 -enable-kvm -kernel /root/virt/Image -m 512 -M virt -cpu host -drive file=/root/virt/ubuntu-virt-15.04.img,id=fs -device virtio-blk-device,drive=fs -netdev type=tap,id=net0,script=no,downscript=no,ifname="tap0" -device virtio-net-device,netdev=net0 -append "earlyprintk console=ttyAMA0 rootwait root=/dev/vda rw" Any suggestion is much appreciated Thanks ! ------------------- Yehuda Yitschak Marvell Semiconductor Ltd.
