Last night I submitted a Ticket to the Digital Ocean asking about virtio, but unfortunately I slept and left the ticket unanswered. Sorry Etel 😀
This morning when I open the Ticket, I give the full Credit Card number, and also my last billing transaction to Etel, and then she charged me $0.25 for verification purpose to the Credit Card and added it to the ballance.
Next, after having the virtio enabled, everytime we want to create a server, the “Enable virtio” button will appear.

And this is the OS Template lists :
So, with the virtio enabled the speed increase, I will try to create a droplet 🙂 Thanks for this information
For the download speed, yes.
But for the IO speed tested with dd and ioping, it still the same.
gan mau tanya… kalau beli di digital ocean itu nanti vps nya ada virtualisasi apa yah? openvz? xenhvm ? atau apa? bisa install ulang OS pilih sendiri kapan pun?
Kalau digitalocean, virtualisasinya KVM gan 🙂
Managemennya pakai OnApp kalau ga salah, jadi bisa install ulang OSnya kapanpun agan mau.
