virtio-scsi are a little bit slower than virtio-blk. with virtio-scsi is a real scsi controller, so, some features like scsi passthrough, trim is working. ----- Mail original ----- De: "Gilberto Nunes" <[email protected]> À: "Alexandre DERUMIER" <[email protected]> Cc: "Gilou" <[email protected]>, [email protected] Envoyé: Mardi 15 Juillet 2014 18:44:10 Objet: Re: [PVE-User] Hot resize of Windows virtio disks ?

I should be more precise: virtio-scsi is working fine since the beginning. (proxmox : scsi disk + virtio scsi controller in options) but virtio-blk was buggy (proxmox : virtio disk) ----- Mail original ----- De: "Gilou" < [email protected] > Cc: [email protected] Envoyé: Mardi 15 Juillet 2014 11:01:26 Objet: Re: [PVE-User] Hot resize of Windows virtio disks ?

However, I can successfully resize C:\ disks on Windows 2008 R2 & Windows 2012, Windows 2012 R2 using the latest virtio drivers, so I guess it was fixed, or I just didn't hit it...
