Xen Orchestra on Ubuntu 15.10 - Complete installation instructions

Danp

Thanks for the pointers. I've made the corrections and now it loaded correctly upon reboot.

scottalanmiller

Any guess which thing that it was?

This is all I have and it works fine....

@reboot	cd /opt/xo-server; /usr/local/bin/npm start

Danp

Had to be the way that I originally created the crontab entry with nano. It all started working correctly once I used your method.

Has anyone else tried migrating the XO VM between servers using XO? When I tried this, the VM was successfully moved, but it appeared to lock up and I had to force a reboot.

Also, what config (VCPUs / ram) are you using for XO? Currently, I'm running 2 VCPUs and 2 GB ram.

I have done this, and noticed it as well. It seems to take a while to actually complete.

My XO server is set up identically.

Edit: Calling @olivier who might be able to better explain the process.

So this script should work.

Going to update my script and test.

Just updated to 4.13 using your script.

Danp

Just updated to 4.13 using your script.

Now the CR feature seems to be busted (appears to be doing a full export each time instead of a delta). If anyone is feeling like living on the edge, upgrade your copy of XO and see if you get the same behavior.

P.S. I took a snapshot of XO before updating, so I can always roll back to 4.12

Danp

Wondering if this issue is due to not rebuilding vhd-util. Rebuilt it, deleting all snapshots, and will then let the job run overnight to see if the deltas are working again.

Danp

The delta exports for Continuous Replenishment is still not working for me after updating to 4.13.

The snapshots are using a new naming mechanism, and the oldest one isn't being removed when each jobs finishes.

olivier

Investigating.

Can you fetch the last version and try again?

DustinB3403

I'm glad the update script works for you.

Wasn't to much to put together.

olivier

@Danp Continuous replication is not using vhd-util from XO: the merge is done on XenServer side.

Danp

Ok... I'm testing your latest fix now.

Much better now. Muchas gracias!

I don't see an update on github what was updated to address the issue?

@scottalanmiller Can you add forever to this script?

Danp

Has anyone looked at XOA to see how they implemented logging?

Danp

Got rid of the crontab entry and created the file /etc/systemd/system/xo-server.service containing the following:

# systemd service for XO-Server.

[Unit]
Description= XO Server
After=network-online.target

[Service]
WorkingDirectory=/opt/xo-server/
ExecStart=/usr/local/bin/node ./bin/xo-server
Restart=always
SyslogIdentifier=xo-server

[Install]
WantedBy=multi-user.target

Seems to be working fine with the added bonus that you can now do things like journalctl -u xo-server -f -n 50.
