Using existing partition

[c0utta]

I'm currently transitioning across from a Debian Squeeze installation to multiple containers on Proxmox. During the transition, I'd like to be able to have the old Debian Squeeze running as a KVM, and reading this post (#51) it indicates that this is possible.

My issue (and probably a show stopper) is that Debian Squeeze is on partition sda1 (and associated sd5 lvm) shared with another used partition sda3. Can the KVM just use the existing sda1 partition and not the whole disk? If so, how?

Thanks in advance.

Hi,
you can edit the VM-config and add something like this:

ide0: /dev/sda1

But in this case your first ide-disk inside the vm is not an real disk (has no mbr/partition-layout) and you must mount the whole disk inside the vm (mount /dev/sda /data). Without mbr (grub) it's perhaps not so easy to boot

Hi Udo,

Thanks for your reply. I have tried both:

ide0: /dev/sda1

and

ide0: /dev/sda

But neither worked (I didn't really expect them to either..)

Partition management is still a "black art" to me anyway, but I'll set up a dual boot Debian/Proxmox until the transition to Proxmox is complete.

Thanks,
