BRRABill's Field Report With XenServer

Simplified: Why would you run XenCenter?
I started out on XC, but now do everything on XO.
I was just wondering why there were always reboots on one, and never on the other.
So it sounds like when 5 comes out, it'll tell you you need a reboot.
It's definitely different than the Windows world. It's interesting to know you can install update on top of update, and THEN just reboot.

And aren't you a XC evangelist for the Windows folk? LOL.

It won't tell you anything, it will display the recommendation for each patch.

Scott has always recommended using XenServer or Hyper-V over ESXi due to the business model. I think his gripe with XenCenter was the limited functionality prior to it being wide open.
But with XO there is very little need for XC any more.
I find XC is easier to manage a VM at times, just because of how I use my system.

Hey when XO displays, I listen.

@BRRABill ahahah

I guess Windows works the same way, but I've always been fearful not rebooting pretty quickly would lead to serious system problems.
Though I am guessing that rebooting pretty quickly after applying patches that require rebooting on XS is probably prudent. Still, I could install during the day and just reboot it at night.

It's not really stability issues, it's that the updates don't take effect until you reboot.

I happened to notice in XO the following...
(xo-web 4.16.1 - xo-server 4.17.0)
Should those be the same? I was pretty sure they were both the same the other day when I upgraded them.
-
@BRRABill No, they can vary depending on the release schedule. My production server is currently
(xo-web 4.16.0 - xo-server 4.17.0) -

Also upgraded one server (of two) to XS7 tonight.

Just remember that migration from XS6 to XS7 is a one way operation.

Why would one ever want to go back?
-
@BRRABill You wouldn't downgrade from XS7 to XS6. However, with one XS6 server and one XS7 server, I could seem someone wanting to migrate a VM between servers and not be able to if the VM resides on XS7.
-
Indeed, you can't live migrate a VM from a recent version of XS to an older one.

But you can go the other way, thank goodness!

Would really suck if you couldn't. Nice that updating isn't too bad. -

Would really suck if you couldn't. Nice that updating isn't too bad.I was certainly happy to have XS installed on USB.
I wonder what it would be like if XS is on the same disk/array as the SR.
-
Has anyone ever done an upgrade to the same version?
By that, I mean, installed, say XS7 over an existing XS7 install?
I am thinking of doing that to test my "clone to a bigger USB" theory.
-
Another question, this one more for general knowledge.
If I were to clone the current boot USB, and then try this upgrade and it bombs, can I just go back to the cloned original setup?
This is the kind of stuff that I don't think you can do, but then @scottalanmiller says ... "you are thinking windows ... Linux is just .... EASY"
