kvm Spice 그래픽 오류: _drawable을 가져올 수 없습니다.

Ubuntu Server 16.04에서 KVM을 실행하고 있습니다. 데스크탑 환경을 실행하는 가상 머신의 해상도를 변경하려고 합니다. 이를 위해 나는 사용합니다가상 뷰어원격으로 가상 머신에 연결합니다.

virt-viewer --connect qemu+ssh://user@host/system myvm  

거기에서 나는 사용한다랜달해상도 변경:

xrandr --output Virtual-0 --mode 1920x1200

그런 다음 UI가 멈추고 아무것도 입력하거나 클릭할 수 없습니다.

호스트의 로그에서 이를 볼 수 있습니다.

((null):3347): SpiceWorker-Warning **: red_worker.c:163:rendering_incorrect: rendering incorrect from now on: failed to get_drawable

여러 번 반복하세요.

가상 머신에 ssh-server를 설치했는데 virt-viewer가 작동하지 않는 것 같지만 SSH 연결은 양호하며 터미널에서 작업을 수행할 수 있습니다. 어쩌면 도움이 될 수 있는 다른 것이 있을 수도 있습니다. 이 설정은 데스크탑 환경(호스트)을 실행할 때 작동했지만 지금은 서버에서만 작동합니다.
