#Reboot and make sure to select Proxmox VE Kernel on the boot loader (grub). 
#If you want to boot by default the Proxmox VE Kernel, please edit the following file:
#  vi /boot/grub/menu.lst


#AFTER reboot only!!
#Install Proxmox VE packages
#Make sure you are running the Proxmox VE Kernel, otherwise the installation will fail.

migration from local to nfs


Proxmox KVM storage migration from local to NFS
In order to be able to use the live partition migration in Proxmox, the KVM partition needs to be on NFS or iSCSI.

Here is the process for an NFS storage.

- shut down vm
- rsync -av /var/lib/vz/images/<VMID> /mnt/pve/<NFS VOL>/images/
- edit /etc/qemu-server/<VMID>.conf
- change ide0: local:<VMID>/vm-<VMID>-disk-1.raw to ide0: <NFS VOL>:<VMID>/vm-<VMID>-disk-1.raw
- start up vm
