Ah, I see...

I hacked a virt-manager, and it can run at Solaris now, I do a test, 
yes, you are right.

Seems here I have to add another question. :)
3, From http://fedoraproject.org/wiki/FedoraXenQuickstartFC6, I can see 
"Installation must be a network type. It is not possible to install from 
a local disk or CDROM. " is it true? As I remember virt-manager will get 
CDROM list for HVM install, can this feature run now? I have no this 
type of machine to test HVM.

BTW, when we create a new DomU, and not use virt-manager, what command 
line we can use? by now I only know virt-install, can xm or virsh create 
a DomU from zero?
