[Xen-users] Xen save takes a long time

[Jonathan Tripathy <jonnyt@xxxxxxxxxxx>]

Hi Everyone,

By default, when I shutdown my Xen host, the system will try and save 
every DomU. I currently only have one DomU in my Xen host, however this 
takes about 7 minutes to save. Since this system will eventually go in a 
colo facility, and will host tens of customer VMs, waiting that kind of 
time isn't an option.
Can some please:

a) Explain why the DomU takes so long to save? Is this normal? The DomU 
has just a small 3G LVM disk which has hardly been used
b) Is it safe, in a hosting environment, to disable guest "saving" on 
Dom0 shutdown, and just resort do guest "shutdown"?
Thanks
