[PATCH] nvmx: fix resource relinquish for nested VMX
The previous order of relinquish resource is:
relinquish_domain_resources() -> vcpu_destroy() -> nvmx_vcpu_destroy().
However some L1 resources like nv_vvmcx and io_bitmaps are free in
nvmx_vcpu_destroy(), therefore the relinquish_domain_resources()
will not reduce the refcnt of the domain to 0, therefore the latter
vcpu release functions will not be called.
To fix this issue, we need to release the nv_vvmcx a...

[PATCH v3 0/4] nested vmx: enable VMCS shadowing feature
Changes from v2 to v3:
- Use pfn_to_paddr() to get the address from frame number instead of doing shift directly.
- Remove some unnecessary initialization code and add "static" to vmentry_fields and gpdptr_fields.
- Enable the VMREAD/VMWRITE bitmap only if nested hvm is enabled.
- Use clear_page() to set all 0 to the page instead of memset().
- Use domheap to allocate the

[PATCH 00/11] Add virtual EPT support Xen.
From: Zhang Xiantao <xiantao.zhang@intel.com>
With virtual EPT support, L1 hyerpvisor can use EPT hardware
for L2 guest''s memory virtualization. In this way, L2 guest''s
performance can be improved sharply. According to our testing,
some benchmarks can show > 5x performance gain.
