Hi Bill:

I may have forgotten about manually changing those two=20
global settings after that particular CSMS re-install.
I've cleaned things up on the CSMS since then. So, unless
I can reliably reproduce with trusted GUI settings, this=20
issue can be closed.

Thanks.

Regards,
Evan

Also you probably want to go into global settings and set your expunge time=
s down from where they are at. By default they keep deleted vms around for =
some time. You can see this if you go to XenCenter and take a look at your =
Hypervisors.=20
