Your most loved* basic client XCP-ng Center 8.0.0 is now released:

https://github.com/xcp-ng/xenadmin/releases/tag/v.8.0.0

*of course XenOrchestra is the most loved advanced client

it's now released! https://github.com/xcp-ng/xenadmin/releases/tag/v8.0.1.26

Hello together,

to avoid more and more confusion about the pieces of the XCP-ng Universe, I'll try to describe what is what.

The Hypervisor, the Host, the Virtualisation Server: XCP-ng

This is the thing you install on bare hardware, it consists of:

• the XEN kernel
• Dom0 - the management domain (it's basicaly a highly custom CentOS with drivers, various services and some glue logic)
• DomU - the VMs, the virtual machines, the things you virtualize
• Love

It's exact the same concept like CITRIX XenServer or CITRIX Hypervisor. XCP-ng is derived from them. Something like a fork, but not so hard.

• issues: https://github.com/xcp-ng/xcp/issues

The basic management software, the windows client, the thing with the tree: XCP-ng Center

• community project
  • issues: https://github.com/xcp-ng/xenadmin/issues
  • download: https://github.com/xcp-ng/xenadmin/releases
• some help from Vates

It's derived from CITRIX XenCenter.

The advanced management software, the web client, the backup solution and more: XenOrchestra

• commercial product from Vates
• community driven
  • issues: https://github.com/vatesfr/xen-orchestra/issues
• can be build from sources with all pro features enabled
  • https://xen-orchestra.com/docs/from_the_sources.html
• only community support

It's not derived from anything (as far as I know).

The ready to use XenOrchestra, the appliance: XOA

• single line to install on XCP-ng
• can be licenced with pro features and pro support from Vates
• is a ready to use VM

The company behind: Vates

Olivier Lambert and his company Vates startet all the jazz. They provide pro support for XCP-ng (the host) and XenOrchestra. They help to sign XCP-ng Center and the XCP-ng Windows Client Tools (and drivers) with an proper EV certificate.

If you have problems to install Citrix(TM) or XCP-ng Windows Guest Tools, please try the first working version of this tool:

Good

Hello all together!

I started to build a little tool, that should help to find the problems before installing/updating the Guest Tools in a Windows VM. For now its only a first start, but it can grow to a very usefull tool.

Any constructive help or hint is very welcome!

Later (so my plans) it should be a part of a new Guest Tools Installer.

Hello, I did today a quick test with GlusterFS. Here is a quick HowTo: https://github.com/xcp-ng/xcp/wiki/GlusterFS

Please feel free to contribute! (to the wiki and here)

And what changes they push to github...

We prepared a pre-release of our PV-Drivers and the Management Agent for you to play with:

https://github.com/xcp-ng/win-pv-drivers/releases/tag/v7.5.0-testsigned-testmode

The drivers are not signed properly, but this will happen as soon as possible. To test the drivers, you have to enable the so called "test mode" on windows, which allows to load testsigned drivers for testing

Make backups! Make Snapshots! So you can rollback if your windows dont want to boot anymore.

So please test and report back here! Thanks for your help!

@eexodus said in Testing ZFS with XCP-ng:

zpool create -f tank /dev/sda

If you have 4k disks (aka Advanced Format) use ashift=12

zpool create -o ashift=12 -f tank /dev/sda

I would say, for the first testing, please use:

zfs set sync=disabled tank
zfs set compress=lz4 tank
zfs set atime=off tank

pool/discs can be live monitored with

zpool iostat -v 1

Hello Community,

I managed to build the XCP-ng Management Agent. Can you please test it?

It's the development version 99.99.99.3, so please use only for test environments. I wanted to know if it's working correctly. I tested to assing a static IP to my Windows 10 Test vm, it worked

https://github.com/xcp-ng/xcp/files/2264386/XCP-ng_WindowsManagementAgent_99.99.99.3.zip

Welcome!

Cert is renewed... the proxy didn't reload after cert renewal...

@stormi I was very busy at work. I check my server...

@jmm you can also build from a tag to get a consitsent state

anyone can request a change in https://github.com/xcp-ng/xenadmin/issues

@okynnor and after you executed the commandline, do the vm's boot?

@axel this is not the "official" way...

Hello,

I just hit a Windows bug while testing the XCP-ng Windows Guest Drivers and Tools. If you have a Windows 10 (1803) VM and installed PV-Drivers (CITRIX or XCP-ng) you may get a bluescreen like this:

Cause

"Addresses an issue that ignores the MM_DONT_ZERO_ALLOCATION flag. This issue leads to degraded performance, and, occasionally, error 0x139 appears." (https://support.microsoft.com/en-us/help/4458469/windows-10-update-kb4458469)

This bluescreen above is the exact error 0x139 --> KERNEL_SECURITY_CHECK_FAILURE

I opened the created minidump in Visual Studio 2019 and was at the exact location, where xenvif hits the bug:

Solution

Install latest Windows Updates bevore installing the Windows Guest Tools and Drivers!

That's also recommended by CITRIX: "If your VM operating system is Windows 10 1803, you must install the latest Windows Updates before installing this [xenvif 8.2.1.175 and above] version of the Management Agent. For more information, see https://support.microsoft.com/en-us/help/4458469/windows-10-update-kb4458469." (https://support.citrix.com/article/CTX235403)

Edit:

I added a hint in the wiki: https://github.com/xcp-ng/xcp/wiki/Guest-Tools#state-of-822200-rc1-and-822-beta

@NamoDev said in No network available in new VM page?:

So I've set up a new XO instance from source

A new one or is this the first XO just set up? Maybe a cache issue in the browser (wild guessing)?

it's now released! https://github.com/xcp-ng/xenadmin/releases/tag/v8.0.1.26
