@Jarland's CatalystHost have recently moved to VirtPanel for VM control. It looks interesting and intuitive, though I don't think I could handle trusting the master CP to an outside company.
Since not everyone will see it, here are some screenshots:
After logging in. Apparently i'm a reseller? THis must be due to having multiple VMs with Catalyst:
Clicking on "Accounts" gives me the 'usual' listing of my VMs:
The control interface for a VM. I'm not sure what the "disk i/o" means.
I can change my VM resources if I so choose to. This is somewhat dangerous, as I have a VM with Catalyst in Texas and Colorado, and I can move resources from Texas to Colorado and vice versa.
I like this disk i/o graph. I wonder where it gets its data from?
There's API access. The API documentation ( http://www.virtpanel.com/documentation/docs-api/ ) is terrible, though.
