>>"you can't online resize a virtio windows bootdisk"
This is strange, this proxmox message occur only if "virtio0:" is used as bootdisk in vm config.
(virtio-scsi are scsi0: in config file)
BTW, I have send a patch ti remove this limitation today, it should be ok for next proxmox release.

I got this error:
you can't online resize a virtio windows bootdisk
And I am quite sure that this worked before...
I used virtio-scsi-pci as backend...
But I will try again and post results later...

What do you mean by "it doesn't work".
Do you have an error message in proxmox ?
(if no, Do you have rescan disks after resize in windows disk management console?)

I don't know if this happen just to me, but I had to reinstall the VM with Windows 2012, and now the hot disk resize doesn't work!...
I used Virtio disk, Raw format, and Type Scsi as VIRTIO!
I also install last version of Virtio-win drivers, with means, virtio-win-0.1-81.iso...
Any advice?

To be honest, I don't know the difference between one and ohter: virtio-scsi and virtio-blk...
Can you point me some docs??
Thanks

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)

Hi,
If so, I indeed would like more information on that bug. 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...
