    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.

    While working last night i noticed one of my backups/pools did this. Got the email that it was interupted but when i looked the tasks were still running and moving data it untill it porcess all vms in that backup job. Edit - note my backup job was run via proxy on the specific pool/job. 2026-02-19T03_00_00.028Z - backup NG.txt Edit 2 - homelab same last backup was interupted. 2026-02-19T05_00_00.011Z - backup NG.txt
