XenServer on two Dell R510's
-
In the NTG Lab, we've got two Dell 510 Servers (Courtesy of the awesome guys over at X-Byte) running XenServer, linked to a Windows 8.1 Pro machine running XenCenter, all using a Drobo B800i as a SAN. I need to get a VM of CentOS 6 (64 bit if possible) running on one of these machines. How do I go about doing this?
-
Do you have a CentOS 6 (Why not 7?) ISO on a share that either XenServer can see?

CentOS 6 is a relabeling of RHEL 6 (Red Hat Enterprise Linux.) XenCenter has a template option for installing CentOS 6 so that you don't have to go through the complete process like you would with a "random" operating system. When you select the "create new VM" option in XenCenter, look for the RHEL 6 64bit template option. This will set a bunch of the settings for you. Most importantly it will enable full paravirtualization for better performance and stability with less overhead. Otherwise full PV will be disabled.

He does, there is a permanently mounted CIFS share called ISO that holds the install media.

Because it is a lab and he's learning how to build VMs. There is a template for CentOS 6 but not for CentOS 7.

Got it.

Why not just use the already existing CentOS 6 template?

That one I don't know, I've always used the CentOS template for this but there may be a reason to use the RHEL template.

Is there both? They would be identical. That's very silly that there are two. The two products are literally the same thing.
-
@scottalanmiller Well, shall I use the one purposed for CentOS?

Sure, that's fine too.
-
@scottalanmiller I selected the template for CentOS 6 64-Bit, what next?
-
Follow the wizard. Ask when you get stuck.

I have no memory of this place...

You'll only need a single virtual NIC for the VM.

One last question, how much storage do I assign to it?

My rule of thumb is 12GB for a stock Linux OS.

why is that your rule of thumb?
-
Plenty of space for a full OS, overhead for logging and normal apps. Mostly just experience.
