7. How do I plan A vmvm? Is there a quantitative standard?
This depends entirely on the configuration of the Virtual Machine and the load pressure. A simple configuration method is to allocate memory according to the memory. The memory allocation volume of each virtual machine + X

XenserverIntroduction
Citrixxenserve is a complete server virtualization platform launched by Citrix. The xenserver software package contains all the features required to create and manage x86 computer deployments running on xen (an open-source semi-virtualized Virtual Machine hypervisor with near local performance. Xenserver has been optimized for both Windows and Linux virtual servers.

During xenserver installation, the system creates a network for each physical network interface card (NIC. Add servers to a resource pool
These default networks are merged so that all physical NICs with the same device name are connected to the same network.
Generally, if you want to create an internal network, use an existing Nic to set a new VLAN or create a NIC binding, you only need to add a new network.

I believe many people are filled with disk space by XenServer log, causing the problem that the machine finally hangs up, I met 2 times (once the pool master hung up, No. 200 people can not work 1 hours). It's a headache.
The server used a long time, XenServer generated a lot of logs, and even some people because the log filled up with spa
