BRRABill's Field Report With XenServer

Simplified: Why would you run XenCenter?
And aren't you a XC evangelist for the Windows folk? LOL.

@BRRABill said in BRRABill's Field Report With XenServer:
it'll tell you you need a reboot.
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. -

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"

Yes you can do that. As the Boot USB is what is running the hardware, the hardware doesn't store any of the boot info.
