    What about LVM+qcow2

    Hi, This is an idea that makes a lot of sense to me, yet I'm not able to find people talking about it so it's probably a bad idea. Still I would love to know why it's bad. Before anyone asks, no I'm not planing on using this in production. According to the docs PVE supports shared LVM storage...

    [TUTORIAL] Low latency storage optimizations for Proxmox, KVM & QEMU

    [TUTORIAL] Proxmox VE vs VMware ESXi performance comparison

    Many discussions have compared Proxmox and VMware from a feature perspective, but almost none compare performance. We tested PVE 7.2 (kernel=5.15.53-1-pve) and VMware ESXi 7.0 (update 3c) with a 32 VM workload to see which performs better under load with storage-heavy applications. The results...

I am very new with Proxmox and KVM in general, so I am going to ask all my questions and hopefully they are not too dumb! 1- Has anyone managed to get ZFS over iSCSI done to EMC storage lineup? (this case is PowerStore) 2- Experience with...

I would like to do a live migration of this disk, to a new storage (LVM storage, iscsi mounted on proxmox). Keep in mind that the VM is running and the...

    Convert Directory storage to lvm-thin?

    I have a PVE host which was originally installed on PVE v3 with Directory type storage for local disk images. It is now running 5.3-5. I would like to have the disk images stored on lvm-thin so that I can trim them (the disks are .raw images). Is there a way of doing this that doesn't involve...

    (coming from VMWARE) Drives are showing OFFLINE in windows installer (iscsi only)
