Virt-manager does auto update from remote hosts.

If you want to edit configs by hand, use: virsh edit <domain>

virsh edit will signal libvirtd to re-read the config file you just 
edited, and virt-manager running on a remote host can get the update.

Also, most edits will not take effect until the VM is rebooted.

For instance:

You want to increase memory in a VM.

# virsh setmem 008065-aberrate.com 1024000

This changes the running VM (if certain conditions are met), but does 
NOT change the config file.

# virsh edit 008065-aberrate.com
    [change the currentMemory value to 102400]

This changes the config, but does not impact the running VM until the 
next reboot.

Good luck!.
