I am running Xen 4.1.2 over Ubuntu server 12.04 - LTS, and I am trying to create VMs using an NFS shared folder, the installation process starts, but when the installation checks the hardware, it says that was not found a HD device and the installation cannot continue. I thought that when I use the NFS option in .cfg files the Xen would emulate a HD device to the guest O.S mapped by /dev/nfs.
Here is my configuration file:
# # Configuration file for the Xen NFS-root instance ubuntu-openstack. # Created by xen-tools 4.2.1 on Fri Aug 23 22:47:02 2013. # # # Common stuff. # kernel = '/xen/imagens/ubuntu-netboot/vmlinuz' ramdisk = '/xen/imagens/ubuntu-netboot/initrd.gz' memory = 2048 vcpus = 2 # Name name = 'ubuntu-openstack' hostname = 'ubuntu-openstack' # # Networking # dhcp = 'dhcp' vif = [ '' ] # NFS options nfs_server = 'ip address' nfs_root = '/srv/nfs4/xen/vms' root = '/dev/nfs'
Any ideas in how to work this around ?
Accepted AnswerRussell PavlicekOnline0Interesting question. I've never done this, but I found the following article on the subject:
I noted the section right after the line: "First, you’ll need to make some changes to the domU’s kernel to enable root on NFS:"
Have you done something similar to make sure the result will work? Or is the error coming before that point?
