Subject: [PATCH 00/16] Nested virtualization for VMX
Date: Wed, 8 Sep 2010 23:22:08 +0800 [thread overview]
Message-ID: <1283959344-3837-1-git-send-email-qing.he@intel.com> (raw)
This patch set is the upgraded version of nested
virtualization for VMX, that allows a VMX guest (L1) to
run other VMX guests (L2).
The nested virtualization for vmx is built on homogeneous
L1 and L2 for better performance and minimal emulation,
the common code involved is small and contained in patch
03/16, for two flags, one for feature availability, the
other for indicating current mode.
The userspace components (xend/xm/xl) is not included since
Christopher's userspace patch has similar coverage. vEPT is
not included as well because it's still WIP.
Major changes to last version:
- address Tim's comments on error handling and others
- split context switch into smaller pieces with certain
restructure for better readability
- update interrupt handling, rewrite comments
- move cpuid into userspace
- etc.
The patch set includes the following patches.
[PATCH 01/16] vmx: nest: rename host_vmcs
[PATCH 02/16] vmx: nest: wrapper for control update
[PATCH 03/16] vmx: nest: nested availability and status flags
[PATCH 04/16] vmx: nest: nested control structure
[PATCH 05/16] vmx: nest: virtual vmcs layout
[PATCH 06/16] vmx: nest: handling VMX instruction exits
[PATCH 07/16] vmx: nest: switch current vmcs
[PATCH 08/16] vmx: nest: vmresume/vmlaunch
[PATCH 09/16] vmx: nest: shadow controls
[PATCH 10/16] vmx: nest: L1 <-> L2 context switch
[PATCH 11/16] vmx: nest: interrupt handling
[PATCH 12/16] vmx: nest: VMExit handler in L2
[PATCH 13/16] vmx: nest: L2 tsc
[PATCH 14/16] vmx: nest: CR0.TS and #NM
[PATCH 15/16] vmx: nest: capability reporting MSRs
[PATCH 16/16] vmx: nest: expose cpuid and CR4.VMXE
Thanks,
