@olivierlambert thanks. I asked. No estimate.

Is there any news about Nested Hyper-V support?

@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.

@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@olivierlambert it is pretty outdated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

@olivierlambert thank you for your comment.

Is there any updates on nested virtualization and hyper-v?

I've tried to run docker on windows 10 vm and didn't succeed on this.

@olivierlambert Thanks. My other instance is on Ubuntu. It updated without problems.
But it seems new version have problems with session timeout. Now It logging out few times a day)

@olivierlambert so Centos 7 is not supported now? And I have to upgrade to Centos stream?

Centos 7 have glibc_2.17 and it can't be upgraded because all system build on this version.

[centos@xoa ~]$ cat /etc/centos-release
CentOS Linux release 7.9.2009 (Core)

with latest update installed.

@olivierlambert I think so.

I have used standard command sequence:

$ git checkout .

$ git pull --ff-only
$ yarn
$ yarn build

Hi!
Today I tried update my xen orchestra on CentOS7 and got this error:

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

@mrnaz the fixed it in version 5.58.1. So update helped.
