As someone with long term neck and shoulder problems, I've used these for years:
https://www.amazon.com/Microsoft-Natural-Ergonomic-Keyboard-4000/dp/B000A6PPOK
I can't type on a normal "straight" keyboard for any length of time without discomfort nowadays; these have been a good compromise between price and comfort, and with slightly better keys than the newer slimline versions.
Unfortunately, it would appear that they have been discontinued - so grab one while you can!
OK, hadn't really thought of it that way.
I've built a fresh Ubuntu 18.04 VM and reinstalled, and all seems happy enough... just running my backup now to check.
Thanks for all the assistance.
Noel
Thanks for the various replies. I did also try going back to the working snapshot and running the update script with "-n lts" - no different.
I have now tried removing the node_modules directory and rebuilding as in the link from Dan - again, no different.
Given that XO is the only thing on this machine, node must have been installed originally with Xen Orchestra. It could have been updated with regular OS updates, I guess, but Xen Orchestra is working at the snapshot point and only fails when I try to run the updater script.
System reports 7.6, and I was apparently able to change to lts. Running the updater again then - same results. So I'm back at my snapshot now, with XO running but unable to update...
Thanks again.
Another update - reverted to the snapshot and ran the updater with -n stable, and got a different set of errors but still a non-starting service...
First error shown is
error /opt/xen-orchestra/node_modules/level-party/node_modules/leveldown: Command failed.

Any further thoughts?

OK, with a backup restored and snapshotted, I re-did the git config and tried the updater again, and it's failed / borked again.
Relevant lines from the log:

Which is the same as yesterday.
I do have the full build process captured - it's nearly 1200 lines, so it didn't seem like a good plan to upload it straight away. There are no errors that I can see, and the only warning is back to node versions:
warning You are using Node "7.6.0" which is not supported and may encounter bugs or unexpected behavior. Yarn supports the following semver range: "^4.8.0 || ^5.7.0 || ^6.2.2 || >=8.0.0"
Any further thoughts?
Thanks for the help, by the way - much appreciated.
Noel
Ah, OK - no, not any more - again, they went in one of the reboots.
I'll restore the backup (figured that one out), take a snapshot and try again.
Yes, as above - the first run I got the git "who are you" warning, so I ran the git configs and re-ran the updates.
Which logs do you mean - are there any others I can look at, or do they disappear on a reboot?
And next dumb question - how do I restore a Xen Orchestra .xva backup into Xen without Xen Orchestra?
Yes, I do have a backup... not that recent, but it will do.
Any idea what went wrong?
Hi Dustin -
That's all that journalctl gives me - I assume this is since the last reboot?
The troubleshooting info is pretty much what I've already got - service status is above, I did the git configs after the first update attempt.
/var/log/syslog has this:

Hope someone can point me in the right direction - I thought it was a good idea to run the update today, and I now have a non-functioning Xen Orchestra instance.
I did get some warnings about node versions, so re-ran the updater with a node version change.
The only error I can identify at the moment is this one in syslog:
xo-server.service: Failed at step CHDIR spawning /usr/local/bin/node: No such file or directory
I've tried re-running the updater with -n stable and -n lts with no joy.
systemctl status xo-server.service shows:
xo-server.service - XO Server Loaded: loaded (/etc/systemd/system/xo-server.service; enabled; vendor preset: enabled) Active: inactive (dead) (Result: exit-code) since Mon 2018-06-25 13:11:32 BST; 4min 23s ago Process: 1141 ExecStart=/usr/local/bin/node ./bin/xo-server (code=exited, status=200/CHDIR) Main PID: 1141 (code=exited, status=200/CHDIR)
Where do I start?
Thanks

@NattNatt - East Yorkshire, so wherever you count that as!
Hi all - wound up here looking for details on Xen Orchestra for a charity virtualisation project!
UK based, self employed half and half IT dogsbody and musician.
@Danp - Yes, that's what I ended up doing. Might just be worth either adding to the script (if that doesn't cause other issues) or at least warning for noobs like me?
@Danp - OK - as I said, I've got round it - but I think there's a spare "edit" in the first post / instructions?
@scottalanmiller - thanks!
@DustinB3403 - I just signed up to say a massive thank you for this - I've been struggling with the previous instructions and going round in circles with no success. I've now used your script to build successfully on a ubuntu 16.04 server and am up and running.
I did find a couple of issues along the way - firstly, is there a typo in the command line? I think the correct path should be github.com/Jarli01/xenorchestra_installer/master/xo_install.sh - I only got it working in the first place by downloading the script and running locally.
Secondly, on my system at least, yarn wasn't installed, so the first run of the script failed - it was an easy enough correction to make, but could be checked and covered within the script?
Anyway, thanks again 
Noel Weston
