[php437]

hi.
I have installing proxmox 1.8. and I have created a virtual machine based on kvm.
I am need to add a physical drive (/dev/sdb1 mount as /mnt/sdb1 in proxmox parent OS) as a drive for virtual machine.
It is possible? thx

Hi,

http://pve.proxmox.com/wiki/Storage_Model

Should give you a good indication of storage management.

Use LVM on that /dev/sdb1 drive of yours

 

[prochap]

edit /etc/qemu-server/VMID.conf -> add line new line

virtioX: /dev/sdb1 or ideX: /dev/sdb1 or scsiX: /dev/sdb1

edit /etc/qemu-server/VMID.conf -> add line new line

virtioX: /dev/sdb1 or ideX: /dev/sdb1 or scsiX: /dev/sdb1

Is this confirmed as working/good practice? If yes, it should go to the wiki (I would do so )!

It works, but you can't migrate such VMs (because they use local devices).

1)
No need to edit it manually.
Just use the "qm set" command.
The manpage of qm is your friend

2)
you can pass on a partition (like /dev/sda1, which inside the vm would be treated as a whole disk)
or you can pass a whole disk (like /dev/sda). The VM inside would then see the already existing partition(s) as well

The example from above would read like this: "# qm set <vmid> -virtio<X> /dev/sda" for a whole disk, using virtio-bock drivers.

What about backup of physical disk?

This seems to be an attractive option for some scenarios which do not involve migrating.
How is vzdump behaving? Will it dump the disk? Can the disk be excluded the usual way?
