Thanks for the reply.
Could you explain me how to start a HVM domU via NFS?? It would very useful
for me... My domU configuration file is:
#
# Kernel
#
kernel = '/usr/lib/xen-4.1/boot/hvmloader'
builder = 'hvm'
#
# Hostname
#
name = 'natty.i2cat.net'
#
# Memory
#
memory = '1024'
shadow_memory = 8
acpi = 1
apic = 1
#
# UUID
#
uuid = '0702dad0-644a-4263-9675-cec03359b677'
#
# CPUs
#
vcpus = 1
#
# Networking
#
device_model = '/usr/lib/xen-4.1/bin/qemu-dm'
vif = [ 'type=ioemu, mac=00:16:3E:FD:77:0A, bridge=eth1' ]
#
# Disk device(s).
#
#disk = [ 'phy:/dev/vservers/natty.i2cat.net-disk,ioemu:hda,w',
# 'phy:/dev/cdrom,hdc:cdrom,r'
# 'file:/images/ubuntu-11.04-desktop-i386.iso,hdc:cdrom,r'
# ]
root = '/dev/nfs'
nfs_server = 'chucknorris.i2cat.net'
nfs_root = '/mnt/virtuals/natty'
boot='dc'
sdl=0
#
# VNC Config
#
vfb = [ 'type=vnc,vncdisplay=96,vncpasswd=ubuntu' ]
serial='pty'
usbdevice='tablet'
localtime = 1
#
# Behaviour
#
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
Related to the second question, I'm migrating virtual machines when my nodes
of the virtualization cluster are collapsed. Most of the nodes are diskless,
so their disk is mounted via NFS connected to a central node. This central
node has a partition in LVM for everyone of the diskless nodes. Then, all
domUs are executed in these nodes must be started via NFS. But these domUs
can be migrated to the central node, so domUs can be started without NFS but
the config should be changed... so it is not a great idea... Then, the idea
is to start all the domUs via NFS independently of the node where it's
executed. I don't know if my explanation is clear...
I hope somebody can help me!
Thanks
