default login is admin/admin

licensing is setup from the Configure or Administration tab.

updates can be applied to the appliance by attaching an update .iso to the vman VM. then go to https:<vman IP address>:5480 to install the update.

update 4/4/2012:
i had an issue getting AD authentication working with virtualization manager recently. the problem was related to an out of date configuration file that still existed after upgrading the appliance to 4.1.
solution offered from support….

ssh into appliance
cd /etc/hyper9
rm hyper9-config-krb5.conf (use sudo)
cp hyper9-config-krb5.conf.default hyper9-config-krb5.conf (use sudo)
