It is difficult to know the source of the problem without more details from your logs. Can you run the following commands on your XCP-ng host and then attach the generated files here? grep -A 15 -B 15 -i error /var/log/xensource.log/xensource > xensource.txt grep -A 15 -B 15 -i exception /var/log/SMlog > smlog.txt dmesg -T|grep -Eiv 'guest|capacity|promiscuous' > dmesg.txt

Ok, my syntax is oudated. resize_rootfs: true growpart: mode: auto devices: ['/dev/xvda3'] ignore_growroot_disabled: false runcmd: - pvresize /dev/xvda3 - lvextend -r -l +100%FREE /dev/ubuntu-vg/ubuntu-lv || true this one works. final_message. doesn't support any macro like %(uptime) %(UPTIME)

@Pilow said in Unable to copy template: something preventing you to patch thoses hosts ? yes.

@olivierlambert New thread is here

I just released 0.0.4! Still an alpha, but it's becoming pretty usable - there was over 60 commits of code cleanup, polish and also limited testing of all visible features - pretty much everything that is now visible in the UI should be operational at this point, option pages, properties of hosts, pools, VDIs, configuration of NICs, even bonding and advanced stuff like pool password / secret rotation. All XAPI actions and commands were already ported over from C# variant, so my focus now is only on finishing it into a final usable product. We also have some features that original client doesn't have (such as XenCache explorer)! Next on my to-do is to add all features that are currently missing completely: HA, GPU, PCIe, VM import / export etc. Note: I will not be porting over any licensed or proprietary Citrix stuff. This tool may work with XenServer just fine, but I will not be porting over any of the proprietary features, because I will never use it and I have no way to test it either.

@Whitebeard my main skill is finding information ( and obscure disk format for backups and migrations )

@MajorP93 It's being packaged at the moment. between this and the testing that needs to be done it might take a couple of weeks to be released, but I can't promise anything yet

@EddieA Can you try differents combinations of passedthrough hardware in this VM ? e.g try with each device one by one at a time; at least in the VM

not looking better today. still not crashed. [image: 1770797403942-62622e51-a19c-43e3-b499-a6fde4124eb1-093f1189-d681-4a45-b0ca-fc72b6e08e9b.png] but before the patches at 48h max, i topped the 8Gb and got the OOM killed process.

@nathanael-h I have not yet tried the XO CSI driver, if I do I will leave feedback on the relevant thread. (I found the one started in 2025 November)
