问题[spice](ubuntu)

我的笔记本电脑上有一个双引导设置：Ubuntu 18.04 和 Windows 10。在 ubuntu 中，我可以在本指南的帮助下使用 qemu 引导到我现有的 Windows 分区。我正在使用的命令是这样的：

sudo qemu-system-x86_64 --enable-kvm -cpu host -smp 8 -m 8192 \
-drive format=raw,file=/dev/nvme0n1,index=1 \
-bios /usr/share/ovmf/OVMF.fd \
-display sdl -vga qxl \
-device qemu-xhci,id=xhci \
-netdev user,id=vmnic,smb=/home/generic/Downloads \
-device virtio-net,netdev=vmnic -cdrom ~/Downloads/virtio-win-0.1.171.iso

最后一行只是安装virtio 驱动程序，所以我很确定我不需要每次都需要它。
第二行确定分区/dev/nvme0n1p1。

该指南提到了 SPICE，这显然对

动态屏幕调整大小，来宾/主机之间的剪贴板等。

我想让虚拟屏幕在调整窗口大小时改变它的大小并调整分辨率。我尝试按照https://www.linux-kvm.org/page/SPICE上的指南进行操作，并意识到这spicec不再是一回事 - 这意味着我无法使用spicec -h 127.0.0.1 -p 5900. Spice 用户手册同意
：

推荐的客户端是 remote-viewer（随 virt-viewer 提供）。
GNOME Boxes 也可以用作 Spice 客户端。
spicec 是一个过时的遗留客户端，spicy 只是一个测试应用程序。

所以我尝试添加-spice port=5900,addr=127.0.0.1,disable-ticketing到我的qemu命令并remote-viewer在spice://127.0.0.1:5009. 这实际上打开了一个香料窗口——所以现在我有两个窗口可以显示我的 win10 客户机。
Spice 窗口在调整大小时反应更好，但它保持相同的分辨率，并在必要时添加白色边框。

问题

如何获得能够很好地适应调整大小的访客系统的无边界视图？
如果这不是一个完全不同的问题：我怎么能只有一个窗口，而不是 qemu 和 spice 窗口？

更多详细信息

当我连接remote-viewer时，它的控制台窗口显示

** (remote-viewer:3066): CRITICAL **: 15:54:52.441: virt_viewer_util_extract_host: assertion 'uri != NULL' failed

qemu输出显示

我是KVM新手，我的图形性能很差。

作为显示器，我使用Spice，视频设置为 QXL。我在两个客人中都安装了 Spice 代理/客户端。

2位客人的表现不佳。体验很滞后，如果我播放 youtube 视频，它会有很多撕裂。此外，分辨率不会根据来宾窗口大小自动更改。

在同一台主机上，如果我在 Virtualbox 中运行 Win10 虚拟机，我将获得更好的图形性能和基于来宾窗口工作的自动分辨率。

我可以尝试什么来改善图形性能？

更新：正如@byte-commander 所建议的，我用 Debian 9 制作了一个新的虚拟机。在这种情况下，自动分辨率有效，但图形性能仍然很差。
