Can you please create a direct console connection on the XEN dom0 for clients to access their domU's on the console directly?
HyperVM has this option where if you setup a VM as "windows.vm", then you can conect to the VM's console by SSH'ing into the XEN dom0 directly, as such:
ssh -l windowsvm@xenserver and it will login to the XEN dom0 as user "windowsvm" and connect directly to the respective VM as well.
I find that the Text Console in CloudMin is just to slow to do much on it, especially if the management server is in one country and the XEN dom0 in another - we have servers all over the globe
What I'm referring to is similar to what's already there, but with direct access to the XEN dom0
