OpenHarmony更新编译问题及解决办法
Linux问题
没有/hgfs
Linux和Windows共享文件夹：/mnt目录下没有/hgfs的解决办法
sudo apt-get install open -vm -toolssudo mkdir /mnt/hgfssudo vmhgfs-fuse .host:/ /mnt/hgfs无法查看共享文件夹
无法查看共享文件夹解决办法
sudo vmhgfs-fuse .host:/ /mnt/hgfs/ -o allow_other -o uid=1000修改缓存大小
修改缓存大小，ubuntu变快
在ubuntu里面，swappiness的值的大小对如何使用swap分区是有着很大的联系的。swappiness=0的时候表示最大限度使用物理内存，然后才是swap空间，swappiness＝100的时候表示积极的使用swap分区，并且把内存上的数据及时的搬运到swap空间里面。两个极端，对于ubuntu的默认设置，这个值等于60，建议修改为10。具体这样做：1.查看你的系统里面的swappinesscat /proc/sys/vm/swappiness#不出意外的话，你应该看到是602.修改swappiness值为10sudo sysctl vm.swappiness=103.但只是临时修改，重启系统后会恢复默认的60，所以，还要做一步：sudo gedit /etc/sysctl.conf在这个文档的最后加上这样一行:vm.swappiness=104.然后保存，重启。设置就生效了。键盘不能使用：
1、关闭虚拟机电源，点击 编辑虚拟机设置 选项 常规，在右下角的 增强型虚拟键盘 中，选择果可用请使用/需要，确定2、备份并删除虚拟机系统目录下的 后缀名为 .vmdk.lck 的文件或文件夹，重启虚拟机Linux拒绝访问
