We have test latest xen on VT platforms with Intel 915/E8500 chipset and Here is the test summary: IA-32: 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) IA-32e: 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) issues: - can not create IA-32e VMX which has >2G memory in IA-32e platform. - vcpu-pin on VMX guest will hang service OS.
