Hey guys, I've been straddling with this issue for quite some time now and I'm getting absolutely nowhere with it. It took me a long time to get XEN up and running on my server.

Hey guys, I've reached the point of setting up VM's on XEN but the net installations seem to be failing when I am in the netinstall on the actual VM, so this leads me to believe that the networking on the host machine is not set up correctly.

OCF_HEARTBEAT_XEN(7) OCF resource agents OCF_HEARTBEAT_XEN(7)NAME
ocf_heartbeat_Xen - Manages Xen unprivileged domains (DomUs)
SYNOPSIS
Xen [start | stop | monitor | migrate_to | migrate_from | meta-data | validate-all]
DESCRIPTION
Resource Agent for the Xen Hypervisor. Manages Xen virtual machine instances by mapping cluster resource start and stop, to Xen create and
shutdown, respectively.
A note on names
We will try to extract the name from the config file (the xmfile attribute). If you use a simple assignment statement, then you should be
fine. Otherwise, if there's some python acrobacy involved such as dynamically assigning names depending on other variables, and we will try
to detect this, then please set the name attribute. You should also do that if there is any chance of a pathological situation where a
config file might be missing, for example if it resides on a shared storage. If all fails, we finally fall back to the instance id to
preserve backward compatibility.
Para-virtualized guests can also be migrated by enabling the meta_attribute allow-migrate.
SUPPORTED PARAMETERS
xmfile
Absolute path to the Xen control file, for this virtual machine. (required, string, no default)
name
Name of the virtual machine. (optional, string, no default)
shutdown_timeout
The Xen agent will first try an orderly shutdown using xm shutdown. Should this not succeed within this timeout, the agent will
escalate to xm destroy, forcibly killing the node. .sp If this is not set, it will default to two-third of the stop action timeout. .sp
Setting this value to 0 forces an immediate destroy. .sp
(optional, string, no default)
allow_mem_management
This parameter enables dynamic adjustment of memory for start and stop actions used for Dom0 and the DomUs. The default is to not
adjust memory dynamically. (optional, boolean, default 0)
node_ip_attribute
In case of a live migration, the system will default to using the IP address associated with the hostname via DNS or /etc/hosts. .sp
This parameter allows you to specify a node attribute that will be queried instead for the target node, overriding the IP address. This
allows you to use a dedicated network for live migration traffic to a specific node. .sp Warning: make very sure the IP address does
point to the right node. Or else the live migration will end up somewhere else, greatly confusing the cluster and causing havoc.
(optional, string, no default)
reserved_Dom0_memory
In case memory management is used, this parameter defines the minimum amount of memory to be reserved for the dom0. The default minimum
memory is 512MB. (optional, string, default 512)
monitor_scripts
To additionally monitor services within the unprivileged domain, add this parameter with a list of scripts to monitor. (optional,
string, no default)
SUPPORTED ACTIONS
This resource agent supports the following actions (operations):
start
Starts the resource. Suggested minimum timeout: 60.
stop
Stops the resource. Suggested minimum timeout: 40.
migrate_from
Executes steps necessary for migrating the resource away from the node. Suggested minimum timeout: 120.
migrate_to
Executes steps necessary for migrating the resource to the node. Suggested minimum timeout: 120.
monitor
Performs a detailed status check. Suggested minimum timeout: 30. Suggested interval: 10.
meta-data
Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5.
validate-all
Performs a validation of the resource configuration. Suggested minimum timeout: 5.
EXAMPLE
The following is an example configuration for a Xen resource using the crm(8) shell:
primitive p_Xen ocf:heartbeat:Xen
params
xmfile=string
meta allow-migrate="true"
op monitor depth="0" timeout="30" interval="10"
