I have not tried Bitlocker. Moreover, it is not clear to me whether the TPM trusted module inside the virtual machine will be available. It seems to me that Bitlocker is a less reliable solution if the encrypted machine falls into the hands of government agencies.

Hello. I try to experiment with encryption of the file system of a virtual Windows server using VeraCrypt. In general, the solution works, but after a while the server freezes. Without encryption, everything is normal. What do you think this may be with? For example, maybe need to add an RNG...

Hello everyone. There was a question about the Trim function for SSDs in Proxmox. Is it necessary and how to configure it? In my case, Raid 1 is built on the 2 SSDs. Are there any recommendations for optimization inside Proxmox itself or maybe inside virtual machines stored on SSDs.

What may be the cause of this problem? How to warn yourself against this? Use ZFS instead of lvmthin?

I managed to remove unnecessary disks. This was only possible after a physical reboot of the hosts. But I don't like this solution.
