@dinhngtu i've manage to fixed it. Your build adds some extra entries in /var/lib/xcp/state.db that aren't in the version from testing that brake things when i downgraded the packages. ipv4_dns VIF.ipv6_dns

@pierrebrunet Thanks for the update. So is there any way to run the reclaimSpace function (i.e from the XO CLI or something, without having to build a whole REST API application or whatever that involves)?

Hello, this issue has been fixed in XAPI 26.1.19-1.1 available in the testing updates. For now you have to configure your VMs manually (https://docs.xcp-ng.org/troubleshooting/common-problems/#pci-passthrough-error-unsupported-msi-delivery-mode-7) but the fix will be activated by default in the future.
