You can use xm to connect to a domain or virtual machine:

xm console domain-id 

This causes the console to attach to the domain-id's text console.

You can use xm to make a domain:

xm create domain001 [-c] 

This creates a domain named domain001 with the file residing in the /etc/xen/ directory. The [-c]option aids with troubleshooting by allowing you to connect to the text console.

You can use xm to save a domain:

xm save [domain-id] [statefile] 

You can use xm to terminate a domain-id:

xm destroy [domain-id] 

This instantly terminates the domain-id. If you prefer another method of safely terminating your session, you can use the shutdown parameter instead.

You can use xm to shut down any domain:

xm shutdown [domain-id] [ -a | -w ]

The [ -a] option shuts down all domains on your system. The [-w] option waits for a domain to completely shut down.

You can use xm to restore a previously saved domain.

xm restore [state-file] 

You can use xm to suspend a domain:

xm suspend [domain-id]

You can use xm to resume a previously suspended session:

xm resume [domain-id] 

You can use xm to reboot a domain:

xm reboot [domain-id] [ -a | -w ]

The [ -a] option reboots all domains on your system. The [-w]option waits for a domain to completely reboot. You can control the behavior of the rebooting domain by modifying the on_boot parameter of the xmdomain.cfg file.

You can use xm to assign a new name to an existing domain:

xm rename [domain-name] [new domain-name]

Domain renaming will keep the same settings (same hard disk, same memory, etc.).

You can use xm to pause a domain:

xm pause [domain-id]

You can use xm to unpause a domain:

xm unpause [domain-id]

This makes the domain available for scheduling by a hypervisor.

You can use xm to convert a domain name to a domain ID:

xm domid [domain-name] 

You can use xm to convert a domain ID to a domain name:

xm domname [domain-id]  

You can use xm to modify a domain's memory allocation:

xm mem-set [domain-id] [count]  

You can use xm to modify a domain's maximum memory:

 
xm mem-max [domain-id] [count] 

You must specify the [count] in megabytes.

You can use xm to modify a domain's VCPU count:

 
xm vcpu-set [domain-id] [count]  

You must specify the [count] in megabytes.

You can use xm to pin a VCPU:

 
xm vcpu-pin [domain-id] [vcpu] [cpus] 

Where [vcpu] is the VCPU that you want to attach to, and [cpus] is the target. Pinning ensures that certain VCPUs can only run on certain CPUs.

You can use xm to migrate a domain:

 
xm migrate [domain-id] [host] [options] 

Where [domain-id] is the domain you want to migrate, and [host] is the target. The [options] include ——live (or -l) for a live migration, or ——resource (or -r) to specify maximum speed of the migration (in Mbs).

To ensure a successful migration, you must ensure that the xend daemon is running on all hosts domains. All hosts must also be running Red Hat RHEL 5.0+ and have migration TCP ports open to accept connections from the source hosts.
