@julien-f Plugin works! Thank you.

@Strebor
You can download it from here:
https://download-ib01.fedoraproject.org/pub/epel/7/x86_64/Packages/a/apcupsd-3.14.14-18.el7.x86_64.rpm
and install.
That is easiest way.
Or you may enable epel repository and install from it.

I had same issue.
doing: git clean -d -f
and then running yarn build again helped.

@olivierlambert problem was fixed. Thank you for help.

@olivierlambert I've set up XOA trial. Will see if problem appear.

@olivierlambert I have remade backup when I saw the problem.
It went without problems.
I will monitor this further and report if it occurs on other VM's

@olivierlambert thanks. I asked. No estimate.

Is there any news about Nested Hyper-V support?

@olivierlambert Hi Oliver,
Did you have a chance to talk about nested virtualization on xen summit?

@Ajmind-0 apcupsd will be most straightforward way.
I'm currently use apcupsd on xcp-ng hypervisors. One of them connected to UPS cable and other take information from apcupsd netserver.
I also have NUT that take information from apcupsd via apcupsd-ups driver. This NUT I need for synology and qnap NASes.

@olivierlambert it is pretty outdated
And this is only proposition to add such option to docs.

@tzerod I'm waiting for this too

@olivierlambert I think using just systemd is more straightforward then forever via systemd.

@tzerod Nested Virtualization doesn't work with Windows guests in Xen.
The same will be in Xen Server, Citrix Hypervisor and Oracle VM Server.

Could you please add a way to run xen orchestra as service via systemd in xen orchestra manual?
For example I'm using script like this:

root@xoa-test:~# cat /usr/lib/systemd/system/xo-server.service

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

[Service]
WorkingDirectory=/opt/xen-orchestra/packages/xo-server/
ExecStart=/usr/bin/yarn start
Restart=always
SyslogIdentifier=xo-server

[Install]
WantedBy=multi-user.target
