Set up and Run Linux Xen Dom0 and DomU VMs

Posted on Jul 13, 2013 by Eric Ma In Linux, Virtualization

The Xen solutions including installing and configuring Dom0 and DomU are summarized here.

LVM volumes as backing for DomU’s file system is an appealing solution to Xen VBD. LVM volumes can dynamically grow/shrink and snapshot. These features make it simple and fast to duplicate DomU and adding storage to DomU. LVM backed DomU is recommended.

DomU installation and configuration

LVM backed Xen DomU is quite stable with high performance that uses unmodified Fedora pv_ops kernel:

  Hi,
  
  You may want to take a look at this: http://wiki.xen.org/wiki/Migration
  
  For TCP analysis, other tools, such as tcpdump, may help you.

    As the output shows, you are building Xen-4.2.1 which possibly require a different method from the one introduced here.
    
    From your output, the error is:
    
    “Connection timed out”
    
    –> check your network.

Hello I am student in technologies, I am working on a project to monitor virtual networks with Lattice Framework, does anyone know how to add the libraries from the Framework to use the Xen Hypervisor?
