BRRABill's Field Report With XenServer

Haven't done this recently but I think you just share it, and put in the creds in XenCenter.
What creds, though? Your user account? Do you create an account for the XenServer?
That would be up to you and is purely a Windows question.

I am looking for ML best practice!

Really pretty trivial, it's a read only ISO store from your desktop.
-
BTW: last night I found there IS a way in XenCenter to force it to check for updates and then force an install.
From the ISO on their webpage, there are probably 25-30 updates needed to my fresh install.
Strangely, most of them needed a reboot which I thought was weird.

sooooo.... how did you force it?

First, if you want it to check for new version of XenServer, you have to go into TOOLS and OPTIONS and UPDATES and select that box.
To check for and install updates, go to the Notifications tab. Then go to UPDATES. Then click on REFRESH. It will give you a list of the updates, and an option to DOWNLOAD AND INSTALL.
I've only been able to install them one at a time.
QUESTION:
It is generally recommended to install every update they offer? -

I thought the updates were cumulative?
OK I just looked, the answer is - sorta, but not exactly.
-
I was really surprised at
a--how many there were and
b--that most of them needed rebootingI thought that was one of the things non-Windows admins always railed about, how you always have to reboot with Windows updates and not so much with non-Windows systems.

Rebooting is generally a good idea regardless. That being said I haven't had to reboot XenServer because of an update in a long time. Although I am running a very out of date version.

Rebooting for security updates has never been a railing point for any sys admin.
A lot of updates don't require the host to be reboot, think of Debian and CentOS. You can patch on the fly.

In XenServer:
When you select a size for a virtual disk, is that the max size it can grow to, or the actual size it is taking up?
For example, with Hyper-V, with a dynamic disk, if you say the size is 40GB, it appears as 40GB to the OS on the VM, but only takes up as much space as there is data on the host hard drive.
And since I picked "thin provisioning" in setup, ALL virtual disks will be dynamic, correct?

Correct, the size of the virtual disk in this instance is the max size the disk can grow.

that depends on the option you picked earlier.
Remember you started your datastore over because Scott suggested that you pick thin provisioning.
Unlike Windows, it's all or nothing so it appears on XS. All VMs are thin provisioned on a disk, or none.
So in this case you don't need to be asked. The expectation is you know the setting of your data store, and that setting will be applied.

Well the BMR test actually went pretty well. Up until boot time, that is.
I am getting this error:
"Windows could not start because of a computer disk hardware configuration problem. Could not read from selected boot disk."Hoping I just need to edit a file somewhere...

Or you could have an out of order drive set like Scott did the other day. -

I've found almost every BMR I've ever done has issues.
I'm using the Datto device, and almost always have to use the ShadowProtect Recovery ISO.

I don't know what a Datto device is, or the shadowprotect (is that a product?) is.
I use Appassure as my backup product.
To do a bare metal restore I have to options: PXE boot or boot from CD/iso.
Then pull the backups down...sometimes the restore process will allow me to provide storage drivers which it will then inject into the new VM. Otherwise I have to boot from the install media and do a repair and provide the storage drivers.
Additionally, I've had recoveries where the system didn't set the boot disk to active so the system would even try to boot.

PXE Boot has nothing to do with it directly. it simply a remote ISO instead of CD/DVD/USB plugged in directly.

Datto is a NAS and ShadowProtect is a software.
