Xen Orchestra - a web solution for XenServer

scottalanmiller

That's for the recap! There has been so much XO discussion recently we need to recenter too!

I like the UI haha.

@johnhooks We'll re-create it for multiple reasons:

we stacked a lot of features inside something not planned for that
so from a dev point of view, the code is messy
from a user point of view, it's not really coherent everywhere
we got perf issues for big infrastructure (1500+ VMs)

Thanks to our experience now, we can rebuild it from scratch with a LOT more in mind. It allows:

a nice refactoring from the dev point of view
using React+Flux for a fully component oriented software
thinking "components" is far far better for dev but also for building generic and powerful UIs
display only what's important

An example for the VM view:

And with a legend:

Be advised, that's a draft; we already made some changes since.

That does look nice. It's not going to be that font though is it?

olivier

@johnhooks haha nope, that's something designed with Paper, IIRC (by my associate, who is ergonomist and spend our IT budget in Apple iStuff hardware )

Should be out tomorrow if we got no QA surprise in the release process: https://xen-orchestra.com/blog/continuous-delta-backup/

I'm very excited to play with Continuous Delta Backups!

We packaged a binary for offline merging into XOA. You'll have to build it yourself because our version is not portable so far.

Clone https://github.com/rubiojr/vhd-util-convert, make and put the vhd-util binary inside xo-server/bin/

We didn't had enough time to make a portable stuff for 4.12

/teasing:

edit: blog post is out: https://xen-orchestra.com/blog/xenserver-vm-continuous-replication/

Currently in QA.

@olivier

cd xo-server/bin
git clone https://github.com/rubiojr/vhd-util-convert
sudo apt-get -y uuid-dev build-essential
cd vhd-util-convert
make
ls
cp vhd-util ~/xo-server/bin

Appears to work, has the WebGui been updated with a new Backup title for Delta or no?

olivier

No new thing in the web UI for continuous delta, it's automatic. If you are on next-release, it should already work now.

edit: it's the same job/backup thing. So restart after update, and re-run your backup jobs. You'll see the oldest delta merged in the full.

DustinB3403

eh, I've completely forgotten how to jump to the next-release....

Not enough coffee.

olivier

Don't forget to copy the vhd-util binary directly in xo-server/bin. The vhd-util-convert folder is useless after the make!

DustinB3403

Think I got it.

Have to test. Does that look correct?

olivier

Yep.

Due to problem with XAPI and metadata import, I decided it's more safe to write ourselve a solution to avoid use of those metadata. XAPI team told me that the code around this is not in a good shape...

So postponed for Monday. Sorry guys, there is some stuff we can't guess before we got trouble inside XAPI ^^

edit: at least our QA pass is useful ^^

mlnews

Maybe time to update XAPI

olivier

@mlnews Problem is also in next XenServer version. So we'll have better luck to write our own solution/workaround for this!

DustinB3403

@olivier question for you.

I Migrated a VM from a shit-box XenServer, and it's running on the other host, but Xen Orchestra doesn't see this VM on the Host.

Any ideas?

So here is a system that I've been running with the Continuous Backup functionality.

Which I scheduled to run every 5 minutes. I would say it works unless the fulls in the 3rd picture should be completely gone.

I know the first picture says, "every hour on the hour" it's simply because I changed the frequency in which the backup runs.
