Xen Orchestra on Ubuntu 15.10 - Complete installation instructions

@Danp where did you put the xo-start.sh script? It should be in /etc

DustinB3403

and what is in

/etc/crontab

?

And this should be what is in "my" /etc/crontab

Danp

Everything looks the same to me. <shrug>

Tried running grep CRON /var/log/syslog but don't see anything useful.

Danp

Works as expected when I run cd /etc && ./xo-start.sh from the command line.

Can anyone else with XO running give the above steps a try and let us know if you're having the same issue?

@Danp sorry I'm just not sure what might be off without more details...

Try adding the XO installation directory to the PATH statement in that crontab. I'm betting it doesn't know where to run things due to the limited environment the system crontabs run in.

If it needs the PATH, then the command is wrong. It should not know where it is.

In my limited experimenting, npm isn't the best implementation of a program. Then we're also dealing with a crontab not running a script/program that we know runs outside of the crontab. At least to me, this just screams that something is missing from PATH at the point it's being run.

Did you put it into root's crontab? That's where it needs to be.

Danp

@scottalanmiller I think so... command was sudo nano /etc/crontab .

I normally have it in /var/spool/cron/crontabs/root, /etc is normally just settings.

Yup, that's where root's crontab is.

You should "never" edit a crontab like that.

You should do sudo crontab -e

Crontabs are meant to be edited using the crontab tool.

Not only does it protect against typos, it protects against putting things in unknown locations

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.
