每当我运行任何类型的虚拟化软件时，Ubuntu 20.04 都会冻结。它会运行良好，然后突然主机就冻结了。什么都无法使用——键盘、鼠标。视频停止播放，音频只是不断循环播放最后说的一句话。我已经等了 5 分钟，它却再也没有恢复。
我尝试过 VirtualBox、VMWare 甚至 GNOME Boxes，结果都一样。
我正在运行 Nvidia GEforce GTX 1060 3GB。
我从日志中找到了这些内容：
11:16:55 AM systemd-udevd: /etc/udev/rules.d/60-brother-libsane-type1-inst.rules:14 Invalid key 'SYSFS'
11:16:55 AM kernel: Initramfs unpacking failed: Decoding failed

$ sysctl vm.swappiness

我为客户机分配了 8 GB 的 RAM 和 4 个 CPU。我在同一个系统上的 Windows 上进行了相同的设置（双启动），运行顺畅。

BIOS
HP OMEN Obelisk 台式机 875
您有 BIOS F.25。
有较新的 BIOS 可用，即 F.51，可以下载这里。看这里。
笔记：请确认我拥有适合您型号变化的正确网页。
笔记：更新 BIOS 之前请做好备份。
初始化系统映像
对于该Initramfs unpacking failed: Decoding failed消息，请使用 重建您的 ramdisk sudo update-initramfs -c -k $(uname -r)。
在命令之前和之后在 /boot 中查找 initrd.img 文件，并注意文件大小是否发生变化。
虚拟机
虚拟机的 RAM 和 CPU 设置过高。请将其设置为 RAM=2048 和 CPU=2。
交换
对于 16 RAM 主机 RAM，除非您正在休眠，否则不需要 18G 交换。将其缩小到 4G 就可以了。
查看 /etc/fstab 时，它显示您正在使用交换分区。要减小交换大小，您必须编辑分区大小并重新初始化交换。
可能更容易改为使用 /swapfile，并删除当前交换分区。
笔记：命令使用不当dd可能导致数据丢失。建议复制/粘贴。
sudo swapoff -a # turn off swap
sudo dd if=/dev/zero of=/swapfile bs=1M count=4096
sudo chmod 600 /swapfile # set proper file protections
sudo mkswap /swapfile # init /swapfile
sudo swapon /swapfile # turn on swap
free -h # confirm 16G RAM and 4G swap
在 /etc/fstab 中更改此行...
从：
UUID=ce9111f7-159f-4b0f-a64e-dab27666db50 none swap sw 0 0
对此：
/swapfile none swap sw 0 0
然后重新启动并验证是否正常运行。
