该解决方案允许执行主要任务，并解决客户操作系统报告的错误消息问题：“drm:vmw_host_log [vmwgfx]] 错误无法发送主机日志消息“。另外，这里提到：“https://unix.stackexchange.com/questions/500178/issue-while-booting-kubuntu-on-virtualbox-drm-vmw-host-log-vmwgfx-error-failed”

解决方案如下：

1. 第一阶段- 使用 Grub2 终端检索可用的视频模式

# On system loading press 'c' on to enter to the Grub2 terminal;
#
# Configure output - optional (not mandatory) step;
set pager=1
#
# list supported video modes - also vbeinfo command can be used here;
videoinfo
#
# note down the target resolution - in my case, it was 1152x864x32;
#
# reboot the system
reboot

2. 第二阶段- 操作系统终端 - 配置 Grub2

# load OS and login using your user account;
#
# start edit Grub2 config file using Vi or your preferred text editor;
vi /etc/default/grub
#
# add or edit the next entries to the config file:
#   GRUB_GFXMODE=1152x864x32
#   GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"
#   GRUB_GFXPAYLOAD_LINUX=keep
# ATTENTION: GRUB_CMDLINE_LINUX_DEFAULT parameter can already contain some other parameters, just append your parameter to the existing list of parameters using the space char as a separator;
# save the file and exit from the text editor - in Vi ":wq";
#
# rebuild the actual configuration of the Grub2 bootloader
grub2-mkconfig -o /boot/grub2/grub.cfg
#
# Reboot the system
shutdown -r now
#
# Enjoy!
