vsphere replication

Multi-source replication If this is an entire instance-level replication, there is no scenario described below.If you are filtering replication on one or more of the primary instances, and after running for a while, how do you want to add a library to this source?

When a snapshot is created, the virtual machine performs a read operation, and Hypervisor examines the snapshot vmdk to see if there are any chunks that have been read.If so, the block is provided for the virtual machine from the snapshot, and if not, the virtual machine needs to read the underlying VMDK. If there is only one snapshot, this is not a problem, but a repetition to read the VMDK.However, if a large number of snapshots exist, such as one per day within two weeks, then hypervisor need

A virtual machine with a snapshot may have an error when making an online storage vmotion, which will cause the VM to turn on the virtual machine again, with the following errors.650) this.width=650; "src=" Https://s3.51cto.com/wyfs02/M02/8D/B7/wKiom1im_NODALsEAAKPlkVjqZ8448.jpg "title=" 1653371960.jpg "alt=" Wkiom1im_nodalseaakplkvjqz8448.jpg "/>There are three ways to solve these problems:1.

to hold virtual machine files → select clone options → Finish　　　　(2) snapshot : A "backup" of a point in time for a virtual machine vmdk file (Note: The backup here is not really a backup, because the original VMDK file is not backed up), you can restore the virtual machine to a moment of snapshot to achieve system recovery, and create a snapshot file. Once the original vmdk file is corrupted, it cannot be resumed normally. Snapshots have parent snapshots and sub-snapshots, and it is believed t

Operating Windows,linux and other virtual machines can be ssh,wmi to operate the shutdown, restart. You can also add a virtual machine to the host, data center by first. Then through the host, data center to manipulate. This is the same thing that can be done with VMware vsphere Client management tools.

It hasn't been updated in weeks, and recently in research vsphere 5,vmware is also pushing the product, using it to make a consolidation with Citrix XenDesktop 5.5, where there are also problems, where the solution is summarized. Problem: When you create a virtual machine using MCS, you find that the virtual machines have just been created and then deleted. Citrix Desktop Studio prompts you not to create a virtual machine.

Therefore, once you modify either of them, the other one will also be affected. in any case, the original object will be modified.Note:To become a python expert, the first thing to note is the change operation and assignment of objects, which are all reference operations on objects. A statement such as a = [] re-binds a to a new object, but does not affect the previous object. however, object
