@poddingue Thank you for the feedback!

As I am typing this, I believe I've found the issue for autostart issues.

My rc.local:

[09:15 REDACTED]# cat etc/rc.local 
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local

sleep 300
/usr/bin/xe appliance-start uuid=00edfd41-1b01-f401-43cb-68201c6415c6

From the commented out section above we can clearly see that correct permissions need to be set on /etc/rc.d/rc.local, while my permissions got back to default values after upgrade, see below:

[09:16 REDACTED rc.d]# ls -al /etc/rc.d/rc.local 
-rw-r--r-- 1 root root 556 Jul 29 16:17 /etc/rc.d/rc.local

I've mounted backup partition and they were properly set on 8.2.

I will make required changes and re-test in the upcoming days, not today.

In regards to "other-config:" CLI commands - colon-vs-equals, I will try do dive into this a little deeper and come back with more info.

Hi everyone!

I've upgraded standalone host from 8.2 to 8.3 yesterday. On 8.2 I was using /etc/rc.local and vApps to autostart VM-s, it was working like a charm, especially since you can delay startup time which is quite handy if you have block based storage that needs long time to boot so you can delay boot of file server VM before the storage boots online for example.

After upgrading to 8.3 I've realized that rc.local + vApps method does not work any more, can someone confirm that?

I've found solution here: https://docs.xcp-ng.org/guides/autostart-vm/#with-the-cli , however since i was typing and not copy-pasting, instead of "xe pool-param-set uuid=<VM_UUID> other-config:auto_poweron=true" on the last part I typed in autopoweron:true, restarted and it does not work.

I typed it with colon (:) again and listed pool param list, then i saw two "autopoweron:true" flags with same value, i decided to type autopoweron:false, then i had 3 flags, two true and 1 false... Later on I realised that i had to use equals (=), so now autostart works.

Is this normal behaviour when using colon instead of equals sign? Please see picture attached:

Also, is there a way to add autostart delay to VMs?

Thanks!

Thank you for the input everyone. I've tested XenAdminQt and it sees iso library, thank you for advice!

Reason for using XCP-ng center is ease of use/simplicity during quick testing deployments in comparison to XO.

Problem persists months later, even with latest xcpng 8.3 updates (in case it might be related)...

Annyone else encountered same problem?

@dinhngtu

Thank you for explanation!

My production servers are currently running XenServer VM Tools for Windows 9.4.2. Would you recommend switching to XCP-ng tools?

In regards to statement few posts above that XCP-ng tools are developed by Vates, does that mean that Vates builds them from scratch or modifies Citrix/XenServer ones?

I am thinking about switching to "XCP-ng windows guest tools 9.0.9137'', production is currently on "XenServer VM Tools for Windows 9.4.2".

Hi everyone,

Did anyone else notice that built in SR "XCP-ng VM Tools" cannot be seen by XCP-ng Center 25.0.4 ?

• Happens on 8.3 and 8.2, did not test below that...
• XO sees it and can mount it
• SR is visible, PBD was not disconnected

Only way for me to get it to work in combo 8.3 + 25.0.4 was to destroy SR and add it from the scratch...
