[one-users] Fwd: problems with VM IPs and disks

[Carlos Martín Sánchez]

Hi,

Hypervisors can only set the MAC address of the VM. In order to configure
the IP inside the guest, you need to use one of the two available methods:

- Instantiate a Virtual Router [1] inside each Virtual Network. The Virtual
Router appliance contains a DHCP server that knows the IP assigned to each
VM.
- Contextualize the VM [2]. We provide packages for the main distributions

Or you could instead download contextualized images from the marketplace
[3][4].
