Xen Orchestra - a web solution for XenServer

DustinB3403

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

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!

@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?

DustinB3403

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.

I think because it was a previous delta job, it didn't modified some old files (I'm not certain of the behavior when changing in the middle of a previous delta job, I didn't personally coded this part ^^)

So is it still working or not?

If not, delete the old backup files, it will re-create the right things accordingly.

DustinB3403

@olivier I'll purge them and have them run every hour.

Will post some new picture tomorrow from home.

DustinB3403

Oh but that was a new backup job that I had built (completely new XO Server as well) so not sure that makes sense.

Maybe it's not compiled right.

DustinB3403

Anyways a new job is scheduled to run in 30 minutes, and then every hour on the hour.

olivier

If it's a new job, you shouldn't have multiple copies of a full VHD. Check your build!

@olivier Is there somewhere specific I should be looking at to see if I'm "current" ?
