@benapetr Nice, great.
How about to implement a launch of CR backup VMs?

@benapetr said in New project - XenAdminQt - a cross-platform GNU/Linux, macOS, Windows native thick client:

you can already hide the templates using View menu (just uncheck you want to display them, they will disappear).

What is the criterion for custom templates?

by default, the usual templates are disabled, but I see them. Disabling custom ones disables all templates.

@benapetr yes, i'm about connections and credentials export\portable mode. Got it.

Wow, great news. Tried it with my pools.
Connected, basic functions is working, handled pool unavailability.

About UI usability:

• templates mixed up with disabled VMs at same root directory. Without any sorting.
  I prefer to never see them, since it not important items.

• After app restart all icons became yellow.
  

• looks like this option do nothing.
  

How about portable mode? App mostly required for asap situations when XO is down.

Tasks still show completed actions, a month ago events.

No way to install updates. New ui less informative than the old one - no packages changelog.

It also take a time to get into new navigation. Instead of static categories at sidebar, now i can't open Backup while inside pool settings. Need to do extra clicks.

i found that whole pool is not alive enough. Can't reboot or mirgate anything. Have issue only with this 1 pool.
Is it safe to reboot hosts?

@DustinB during a week? at which moment? latest.

@DustinB as i say, XO.

@olivierlambert
XO been updated few times during this week. xen 8.3.

i'm dunno what to search at logs. See nothing interesting.

Well. i have anti-affinity tags - 2 vms on 2 hosts feat this rule. And rule for resource usage.
Maybe they could conflict, but why to move same VM thousands of times?

This config works fine for a years, issue begins at October 10, 2025 at 12:25 PM (6 days ago). Maybe updates related.

one VM migrating every minute for a long time.

pool

@pierrebrunet fixed now, thanks.

@olivierlambert yes.

@olivierlambert 8.3

After commit 36d1e883e2ef02375ec7cd0cf6170cde167a5974 everything looks like

Every disk created by XO not supported by XO? What a criteria of "unsupported"?

I found that mac address and disks are not syncing. Is it possible to add them?

@psafont
nvm something weird happens. I removed cert and everything fixed. Thank you.
Need to specify extention xe pool-uninstall-ca-certificate name=sdn-controller-ca.pem --force

But this cert shouldn't exist at backup because i never use sdn, plugin is disabled. Other hosts has no this cert. Looks like bug?

@psafont
is it safe to remove it on production pool?

whenever the SDN controller is turned on.

so, i can do something on new host, before joining into pool to generate this cert?

i tried https://docs.xenserver.com/en-us/xenserver/8/dr/backup.html#back-up-single-host-installations but, "command not found".

At this time, the meta restore works perfectly. I got all my VMs back, but

• since I don't believe in success, I didn't shut down the unavailable slave host, where the VMs was still running.
• After restoring on a new master, all the VMs were also running.
• except for IP conflicts, in that case I had double VDI usage!
• The old server was shut down ASAP, but some VDIs were still corrupted anyway.

This wasn't a critical issue, but after EMERGENCY restoration, I expected that the host would be in emergency mode and the VMs would be halted.

And next problem. How to restore info about VMs?
2nd affected pool https://xcp-ng.org/forum/post/95369 lost master, all VMs now running on slave which i can't connect.
If setup new host and reconnect it to SR, i only can get a VDI, not VM itself.
