At our side, HyperV 2022 is runnig now on CU9, it looks like CU9 is way wores than CU8. We have much more trouble again than with CU8. CU8 was not really perfect, but better then CU9.
Also i cant say that using the Agent as a workaround solves the problem. Fullbackup with the Agent 100% causes the problem, at least at the starting phase.
Also it looks like most problamatic VMs are the migrated ones from our old 2019-Cluster. But some new ones are even bad. And it seems not at to be a matter of VM size.
I am really thinking of migration from HyperV to Proxmox.
Is there any other place out here where you can read about this problem then here?!
