julien-f Plugin works! Thank you.

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olivierlambert it is pretty outdated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
