In this case, you need to modify the HA restart policy in the properties of the virtual machine. Figure

BKJIA exclusive Article] XenServer 5.6 I have been using it for quite a while, and I feel good stability and performance, so now we have changed all the virtual machines in the company's internal machine room to XenServer 5.6. Of course, the original FreeBSD jail is not converted because it is used well ), I also installed XenServer 5.6, removed the display, keyb

A resource pool consists of multiple XenServer host installations that bind together to form a managed entity.Resource pools allow you to treat multiple servers and their connected shared storage as a single unified resource, and support the flexibility to deploy virtual machines based on their resource requirements and business priorities. A pool can contain up to 16 servers running the same version of XenServer
