high IO delay

Aha you are probably thinkin about HA. That one is with shared storage,so CEPH,NFS,etc. ZFS and hardware raid don't support HA in any way.
 
I'm having the same problem.

I have an intel I7 12000
1 SSD Nvme
2 HDD SATA3

Each disk is mounted as EXT4 and I use "Directory" as storage.

No raid.

If I install Windows using Qcow2 disk in HDD I get 100% disk usage and 1mb speed

I'll thank any help.

This is not happening in Linux installations. In Parrot, I can change the Qcow2 from SDD to HDD and still works fine.

I have seen that, after a lot of time waiting (maybe 1h), it works fine until next restart.

When system boots, it has the same behavior :(

I'll thank any idea.
 
Thx

It,s a fresh w11 install and I have made it almos work activating unsecured cache.

But i guess thats not the solution.

Sometimes I think Proxmox is not good for windows clients.

May be the should be a better option for my needs. A cibersecurity lab for 5 VMs based on I7 64gb and several disks.

I apologize for my language, Im spaniard and writting on mobile right now. It's not easy to me :)
