BRRABill's Field Report With XenServer
-
@BRRABill said:
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?
Dynamic is the wrong term. Thin Provisioned is the real one. Dynamic is a Microsoft only term for thin provisioned. Thin Provisioned is the name of the technology across the board, Dynamic is a term for the use of Microsoft's LVM technology that allows for thin provisioning. So no, using this won't install a Windows LVM, but it will be thin provisioned

I'm using the Datto device, and almost always have to use the ShadowProtect Recovery ISO.
Isn't that how it is supposed to be restored? When I look at their vendor's guide that's what it says to do.

I don't know what a Datto device is, or the shadowprotect (is that a product?) is.
Datto is a NAS and ShadowProtect is a software.
Datto is a backup appliance build on ShadowProtect. It's an all in one much like Unitrends but unlike Unitrends, Datto buys the backup software from StorageCraft instead of making it themselves.

So it was a partition issue in BOOT.INI.
The partition was originally set to (2). I set (0) and got an NTOSKRNL error.
I set it to (1) ... and the server booted. Or, it is is appearing to boot. We shall see.
I also ran the XenServer "fixup" program. Anyone know if that is officially needed, or only if you run into problems? (I definitely needed it when importing the VHD.)

They have their own Datto branded recovery environment you are supposed to use. But, it never seems to work.
Me being on Server 2003 causes issue too, I think.

Well, now there is another issue, but I know how to fix this one. (Had the same issue on a BMR of my other failed server.)
Strangely enough, there is a post on SW about this error (that was not fixed) but the posted posted a picture of his monitor, which was the old fashioned type. (This was in 2009.)

That issue is now fixed!
Good thing I remembered that!

Should I install XenTools?
-
Yes, you always need the PV drivers for any hypervisor that you want to use (including Hyper-V) or you get crappy performance.

Are those included in the install "XenTools" option?

They are the XenTools.

I was not able to adjust memory before. Now after XenTools I can. (You can also see memory usage which is nice.)

Not to side track this thread (apologies to @BRRABill ), what is the "hyperconverged" equivalent in the XenServer world?
To all you XS experts, what is the "hyperconverged" equivalent in the XenServer world?
Similar to Starwind in the Windows world
XenServer is natively that in the Xen world. Nothing additional needed.
If you had 2, 3 or more XS bare metal installs with local drives, how do you "hyperconverge" all the local disks?
Are you saying with XS the "hyperconvergence" just auto-magically happens?
Of course not, but it doesn't for any platform. If you're setting up a greenfield situation, then you design it from the ground up with XS with single shared storage.
Let's try this again:
In Windows, you can take multiple boxes, add Starwind or Datacore = hyperconverged using local storage (no SAN needed).
How do you do the same thing with XS?
This can do HC for XenServer:

If you REALLY REALLY WANT a gui to get HA setup and running on XenServer, maybe give HA-Lizard a look. Haven't used it myself yet (single host), but I've heard it talked about enough to remember it.... the name is kinda memorable.

It's something I want to configure as well, 2 new host, and then download the HA-Lizard client to both, supposedly it handles the entire configuration from what @halizard said in a previous post.

XS (and XO) show the provisioned size of the virtual disk. Is there a way to show how much space it is actually taking up?
(For example in Hyper-V you could just look at the size of the VHD.)

Same, you either look at the storage device and query it and/or you look at the size of the filesystem image file.
-
Yep there is.
Go to the Dashboard firstFrom the dashboard find the Storage Repository (SR)
Click on it.
Now scroll down a little and you'll see your VHDs

I fumbled around for about 5 mins before I bumped my way into this.
