New Defaults in 2.3... why ?

[vitor costa]

With version 2.3 some new defaults... The proxmox team, or anybody, can explain the motivations in this new defaults ?


as roadmap 2.3:

• qcow2 as default storage format, cache=none (previously raw)
• KVM64 as default CPU type (previously qemu64)
• e1000 as default NIC (previously rtl8139)

its well documented in the notes

but

e1000 and kvm64 and overall has provided better comptability and speed especially with kvms. This was partially driven by a number of form posts where use thereof resolved a number of quirkies.

qcow2 is needed if you want KVM live snapshots.

(Backups works with all storage types)
