xenserver vmware

The server has been in use for a long time, XenServer produced a lot of logs, and even some people because the log occupied space,Cause problems with the system: The XAPI crashes, or the system is stuck, and the restart is not valid.So we have to look at the log from time to time to see if the logs occupy space.Check the system disk usage first (xenserver default is 4G system space)[Email protected] log]#Df

XenServer default is 4G system space, and these log files will occupy a lot of system space, the log file fills up, will cause the system problems: XAPI crashes, or the system is stuck, restart is not valid.

same as the above EC2 Automation to create a host, we encountered a problem, that is, each new VM, its IP address and host name, etc. after replication, can not automatically update. I have consulted some peers, may be they do not have such a large-scale use of xcp/xenserver, so the xencenter inside the creation of a good machine, and then through the console to modify the IP address and host name and so on. As a result, I searched repeatedly on Goo

XenServer can mount an ISO image installation system by creating a local ISO storage or NFS storage. For Linux, it can be installed through the network http or ftp. The following record shows that XenServer installs Debian and CentOS systems over the network. Create a vm: xe vm-install template = Debian \ Squeeze \ 6.0 \ (32-bit \) new-name-label = debian6 sr-name-label = Local \ storage # Return to the vm

XenServerDomain0 memory Adjustment XenServerDomain0 uses MB of memory by default. Each time a VM is started, a Qemu-DM process is started in Domain0, occupying approximately 6 MB of memory space, therefore, when the number of virtual machines is large, we need to increase the Domain0 memory to support more virtual machines. Because Domain0 is a 32-bit operating system, the maximum memory size supported is 4 GB. For how to change the Domain0 memory, refer to CTX124806-XenServerSingleServerScalabi

Today's XenServer also has a snapshot technology, if you are doing some dangerous operations, you can take a snapshot, so that even if there is a problem, you can quickly recover. Snapshots can save the state of a virtual machine at a point in time, and can be recovered whenever an error occurs. But if you forget to take snapshots, or if you have trouble making snapshots every time, or if some virtual machines need to be backed up every day, then sna
