I thought it would be helpful for all of the engineers out there that have a VMware ESX background and are starting to implement Citrix XenServer. There are a lot of similarities between the two virtualization platforms.
One of the issues I ran into recently was the changes made to a host via the cmd line not displaying in the XenCenter management console. To fix this you can issue the “xe–toolstack–restart” command to restart the management stack on the XenServer host.
This command is the first thing you should try if there is any type host connectivity or pool issue in XenCenter.
This is similar to the VMware ESX cmd “service mgmt-vmware restart”.
