We have test latest xen on VT platform with Intel 915 chipset and Here is the 
test summary:
 
IA32: 
 Build&Boot SMP xen0 without problem
 Can startup unmodified 2.4/2.6 linux on VMX domain 
 Can startup VMX & Xen with different configuration
 Part of LTP runs well in VMX domain(2.6)
 
IA32E: 
 Build&Boot SMP xen0 without problem
 Can startup unmodified 2.6 linux on VMX domain 
 Can startup VMX & xenU with different configuration
 Part of LTP runs well in VMX domain(2.6)
Key issues of VMX domain:
 
 Can NOT startup Windows Domain
 IA32 VMX domain can not work on IA32E platform
Other issues:
 Cannot enter run level 5 for RHEL4U1 IA32E guest
 Install windows xp with add lapic=1 will crash guest OS
 Install HCT from CDROM on windows xp guest may crash guest OS 
 "vcpu-pin" will cause service OS hang 
 Installations of SUSE10 IA32, FC2 IA32 failed on both IA32 and IA32e 
hosts.
 Installations of RHEL3U5 IA32e, FC2 IA32e and SUSE 10 IA32e failed on 
IA32e host.
