 ## Installing Proxmox VE 7 on a non-Debian system

 The web panel is actually opened in the container, but the network has used the host mode, the port of the PVE is about the same as the port of the host used
 
 There are many bugs need to be fixed, welcome to PR to solve the problem, the actual test on the Ubuntu system host machine to install ```Proxmox VE``` panel success, solved the problem of installing ```Proxmox VE``` over the network can only be used to use the Debian system as a host machine!
+
+## Optimizing the memory footprint of Proxmox-VE on low-configuration systems
+
+The following optimizations can reduce the memory usage by about 400M, which is better than nothing.
+
+### Reduce the number of max_workers
+
+Execute the following command to query
+
+```
+cd /usr/share/perl5/PVE/Service
+grep 'max_workers => 3' *
+```
+
+you can see
+
+```
+pvedaemon.pm:    max_workers => 3,
+pveproxy.pm:    max_workers => 3,
+spiceproxy.pm:    max_workers => 3, # todo: do we need more?
+```
+
+The default max_workers is 3, you can modify the corresponding file, the minimum max_workers can be 1, you can use the following commands to modify them:
+
+```
+sed -i "s/max_workers => 3/max_workers => 1/g" /usr/share/perl5/PVE/Service/*
+```
+
+### Deactivation of HA services
+
+Clusters (multi-nodes) can use the HA service, if it is a single node, or there is no need for HA use, you can execute the following command:
+
+```
+systemctl stop pve-ha-lrm.service 
+systemctl stop pve-ha-crm.service 
+systemctl disable pve-ha-lrm.service 
+systemctl disable pve-ha-crm.service 
+```
+
+### Disable firewall service
+
+The service can be deactivated by executing the following command:
+
+```
+systemctl stop pve-firewall.service 
+systemctl disable pve-firewall.service 
+```
+
+### Discontinuation of cheduler service
+
+If you don't need scheduled tasks, such as backups and synchronizations, you can deactivate the service by executing the following command:
+
+```
+systemctl stop pvescheduler.service
+systemctl disable pvescheduler.service
+```
+
+### Discontinuation of Spiceproxy service
+
+If you do not need to use Spice for VM/container linking (the Arm version itself does not support Spice), you can deactivate the service by executing the following command:
+
+```
+systemctl stop spiceproxy.service 
+systemctl disable spiceproxy.service 
+```

 开设出的面板实际是开设在容器内的，但网络已使用host模式，PVE的端口约等于就使用的宿主机的端口
 
 有许多错误需要修复，欢迎PR解决问题，实测在Ubuntu系统的宿主机上安装```Proxmox VE```的面板成功，解决了通过网络安装```Proxmox VE```只能使用Debian系统做宿主机的问题
+
+## 在低配置系统中优化Proxmox-VE的内存占用
+
+以下优化可以减少400M内存左右的占用，聊胜于无。
+
+### 减少max_workers数量
+
+执行下述命令查询
+
+```
+cd /usr/share/perl5/PVE/Service
+grep 'max_workers => 3' *
+```
+
+可见
+
+```
+pvedaemon.pm:    max_workers => 3,
+pveproxy.pm:    max_workers => 3,
+spiceproxy.pm:    max_workers => 3, # todo: do we need more?
+```
+
+默认的max_workers是3，可以修改对应的文件，最低max_workers可为1，可使用如下命令进行修改
+
+```
+sed -i "s/max_workers => 3/max_workers => 1/g" /usr/share/perl5/PVE/Service/*
+```
+
+### 停用HA服务
+
+集群(多节点)可以使用HA服务，如果是单节点，或者没有HA使用的需求，可以执行下述命令禁用
+
+```
+systemctl stop pve-ha-lrm.service 
+systemctl stop pve-ha-crm.service 
+systemctl disable pve-ha-lrm.service 
+systemctl disable pve-ha-crm.service 
+```
+
+### 停用防火墙服务
+
+可执行下述命令停用服务
+
+```
+systemctl stop pve-firewall.service 
+systemctl disable pve-firewall.service 
+```
+
+### 停用调度服务
+
+如果不需要计划任务，如备份、同步之类的任务，可执行下述命令停用服务
+
+```
+systemctl stop pvescheduler.service
+systemctl disable pvescheduler.service
+```
+
+### 停用Spiceproxy
+
+如果不需要使用Spice进行虚拟机/容器链接(Arm版本本身不支持Spice)，可执行下述命令停用服务
+
+```
+systemctl stop spiceproxy.service 
+systemctl disable spiceproxy.service
