proxmox 7.0-14+1 VE and vm EFI veryslow

[marcbe]

I have a windows 10 pro on EFI vm very slow, hours not minutes to boot, on HDD ( I cannot move on ssd), the HD is new, 30gg, toshiba n300 4TB, fast when I want to copy files or boot other vm. On this hdd there is NOT other vm running.

Does anyone can indicate why ?

What is the best HDD configuration of VM to improve speed of vm ?

I mean:





Thanks Marcello

the smart data of disk tell that is ok and working fine.

I'd start by running some read/write tests directly from your host (PM I mean). If those seem to work fine next - do some benchmark from a VM. What is your VM harddisk controller setup? How 'bout changing your virtual controller to Virtio SCSI? Also what's the storage type - ZFS/ext4-lvm/thin? How did you mount your disk to PM?

In tabs linked above there's pretty nothing much to really affect your drive speed (except disk cache perhapse - but that wouldn't cause that much performance loss/increase anyway). Hours too boot seem to be a hardware issue...

Allready virtio SCSI, I am using lvm-thin in Proxmox

you use SATA, not VirtIO SCSI.

(you configured a VirtIO SCSI controller but you attached your virtual harddisk with SATA).

the vm with problem is a result of recover by iso is the only efi vm in proxmoxo 7 and the only vm so slow

dev/sde is the disk where is stored the vm "guilty"

Ohps sorry, my mistake

Thanks, the performance are now fine.

But the boot show me a black screen persistent. Do you have any suggestion ?

You've probably changed disk/controller type - your VM OS cannot recognize (yet). Before changing disk config you should create a tiny new disk using virtio scsi type. Then install virtio scsi drivers under VM to it. Finally shutdown VM, change your main disk type and boot again (also remove temporary drive since it's no longer needed).
