[Xen-users] migrate question

["tgh" <tianguanhua@xxxxxxxxxx>]

Hi

I have setup xen3.0.2.on two nodes, 

I try to migrate a vm from one to another ,

I have modified xend-config.sxp ,by uncommenting    (xend-relocation-server yes)   and    (xend-relocation-port 8002)

I put the vm conf file and img file in a  nfs node  which the two xen node can get access to

 

but it does not work with the error as follows

Error: (104, 'Connection reset by peer')

 

 

 

Could anyone help me ?

Thanks in advance

# The hosts allowed to talk to the relocation port.  If this is empty (the

# default), then all connections are allowed (assuming that the connection

# arrives on a port and interface on which we are listening; see

# xend-relocation-port and xend-relocation-address above).  Otherwise, this

# should be a space-separated sequence of regular expressions.  Any host with

# a fully-qualified domain name or an IP address that matches one of these

# To bridge network traffic, like this:

#

# dom0: fake eth0 -> vif0.0 -+

#                            |

#                          bridge -> real eth0 -> the network

#                            |

# domU: fake eth0 -> vifN.0 -+

#

# use

#

# (network-script network-bridge)

#

 

# Your default ethernet device is used as the outgoing interface, by default.

# To use a different one (e.g. eth1) use

#

# (network-script 'network-bridge netdev=eth1')

#

# The bridge is named xenbr0, by default.  To rename the bridge, use

#

# (network-script 'network-bridge bridge=<name>')

#

# It is possible to use the network-bridge script in more complicated

# scenarios, such as having two outgoing interfaces, with two bridges, and

# two fake interfaces per guest domain.  To do things like this, write

# yourself a wrapper script, and call network-bridge from it, as appropriate.

#

(network-script network-bridge)

 

# The script used to control virtual interfaces.  This can be overridden on a

# per-vif basis when creating a domain or a configuring a new vif.  The

# vif-bridge script is designed for use with the network-bridge script, or

# similar configurations.

#

# If you have overridden the bridge name using

# (network-script 'network-bridge bridge=<name>') then you may wish to do the

# same here.  The bridge name can also be set when creating a domain or

# configuring a new vif, but a value specified here would act as a default.

#

# If you are using only one bridge, the vif-bridge script will discover that,

# so there is no need to specify it explicitly.

#

(vif-script vif-bridge)

 

 

## Use the following if network traffic is routed, as an alternative to the

# settings for bridged networking given above.

#(network-script network-route)

#(vif-script     vif-route)

 

 

 

## Use the following if network traffic is routed with NAT, as an alternative

# to the settings for bridged networking given above.

#(network-script network-nat)

#(vif-script     vif-nat)

 

 

# Dom0 will balloon out when needed to free memory for domU.

# dom0-min-mem is the lowest memory level (in MB) dom0 will get down to.

# If dom0-min-mem=0, dom0 will never balloon out.

# In SMP system, dom0 will use dom0-cpus # of CPUS

# If dom0-cpus = 0, dom0 will take all cpus available
