BRRABill's Field Report With XenServer

BRRABill

The VM that I exported seems to have created a vApp.

What is that?

olivier

Yup
Yup

But you need to define a default SR on any pool you got. Eg: xe pool-param-set uuid=<pool-uuid> default-SR=<sr-uuid> (with the SR UUID of the local storage if you don't have a shared storage).

You can also do it with XenCenter or XO (see https://xen-orchestra.com/blog/set-the-xenserver-default-sr/ )

A live migration won't interrupt the VM, so even with XO on it: doesn't matter.

But to clarify ... you DON'T need a pool? or do you?

@Danp said:

I can answer that for you. Yes, you can migrate between hosts in separate pools (technically, a lone XS is in it's own pool).

olivier

Yes, as @Danp said, there is always a pool: a "single" host is by default in a pool with no name label.

XenCenter choose to hide this, not us.

BRRABill

@Danp @olivier

Thanks @Danp ... I think the thing that was throwing us here (who thought it was not possible outside a pool) was that a standalone is actually a pool

Converted my first physical server to a production XS this morning.

So far, so good.

BRRABill

Question:

On the new production server, it is not reporting the space taken by my new VM.

This is what is says:

Total: 871.8 GiB
Currently used: 5.2 GiB
Available: 866.5 GiB

But for example the new VM I migrated over has at least 100GB.

Why would it not be reporting this?

Thin provisioning?

But there is 100GB of data actually on the drive.

you have to refresh. Refresh doesn't happen automatically.

Ah.

What is this? 1973?

I kinda asked/thought the same thing. Having to manually fresh, or relaunch the application just seems odd.

FTFY

Dashrender

Did refreshing it solve the problem?

BRRABill

Yep.

Rescan is actually the word they use.

What does that do exactly, I wonder?

Did you ever do this through XC?

I could not find the option there.

Am I clear... the issue is that XO only refreshes the data as to drive sizes on a page refresh?

No you have to click the "rescan" button or it never does it. At least that is what I am seeing.
