?In the "real" world, I have never seen a XenApp/TS/RDS environment where the servers were not rebooted on a scheduled basis. I have seen daily, weekly, monthly and everything in between reboot schedules. It really depends on the apps installed on the servers and how crappy the apps are. Usually the daily reboots are caused by an apps or combination of apps that eat memory and never release it and the server wil suffer some type of memory exhaustion necessitating the reboot schedule.
In the AD world I also participate in, IF the DCs are nothing but DCs AND apps are not hard coded to a specific DC or groups of DCs, then DCs can be restarted as needed or required. If the DCs run other functions like file server, SQL server, Exchange server, terminal server, etc etc etc, then it can be a real pain to get the time or approval to restart a DC. The project I am on now, the in-house devs have unfortunately hard-coded specific DCs (and for some apps the DC name AND IP address) in some of their web apps. Those DCs can only be restarted during the monthly approved maintenance period.

I'm not looking to reboot systems just for the heck of it either. But I've heard SA's go "Nope, no way, nada, niet, don't reboot for anything no way no how", even after OS level patching. And there have been the people on the other side of that fence that say to treat it like you would a physical server. I'm trying to get a feel for what happens in the real world, not the theoretical world of test labs and sales meetings. John M.

I'm trying to get some straight information on doing maintenance reboots of virtual systems. Some people I've talked to say yes, others say no. I've been doing systems admin work for a long time now, but only recently have had to get up close and personal with VM's on ESX hosts. Yes? No? Why or why not? Learning new stuff is a good thing.
