I suggest you research what ports Xen migration occurs on, then check that these ports are not being blocked.

Hello Xen Users and Developers,

I am running 3 guest domains on a node. Following is the information:

[*root@dmz02 fedora]# xm list*

*Name ID Mem(MiB) VCPUs State Time(s)*

*Domain-0 0 255 4 r----- 66.2*

*vcl-dmz02 1 256 1 -b---- 1.1*

*vcn-dmz02 6 256 1 -b---- 0.3*

*vcs-dmz02 7 256 1 -b---- 0.3*

I am trying to perform live migration using the command:

(dmz03.ornl.gov is also running Xen-3.0.3 and is running 3 guest domains of it’s own)

*xm migrate --live vcs-dmz02 dmz03.ornl.gov*

*Error: can't connect: No route to host*

*Usage: xm migrate <Domain> <Host>*

* *

*Migrate a domain to another machine.*

* *

*Options:*

* *

*-h, --help Print this help.*

*-l, --live Use live migration.*

*-p=portnum, --port=portnum*

* Use specified port for migration.*

*-r=MBIT, --resource=MBIT*

* Set level of resource usage for migration.*

* *

* *

* *

So, apparently dmz03.ornl.gov cannot be seen from dmz02.ornl.gov. However, when I run “ping”, I GET THE FOLLOWING OUTPUT:

[root@dmz02 fedora]# ping dmz03.ornl.gov

Can someone please suggest what the problem might be?

Thanks,

Nikhil
