similar to: [PATCH] a clean up to vmx.c

This patch clean up VMX builder. Since now we have vmxloader, old code loading linux kernel directly is not needed. 1. remove linux parameters. 2. remove init ramdisk. 3. remove e820 memmap config file parse. Also e820 map handling code is changed in vmx_setup_platform. 4. remove provisional GDT, and construct_init_guest_vmcs is updated greatly. 5. remove some ugly tailing space. Thanks Keir for

Cleanup vmx vmexit handler. Current code doesn''t handle vmexits caused by triple fault, INIT, SIPI, etc, which are listed in IA32 Architecture System Programming Guide 2, Appendix I VMX Basic Exit Reasons, and calls __hvm_bug() when not handling such cases, actually domain crash should be good enough. Also various coding style cleanups. Signed-off-by: Xin Li <xin.b.li@intel.com>

Ian, Keir, This patch is to boot 32-bit VMX guest on the 64-bit host. Double-compile is used to make both 64-bit guest and 32-bit guest can work, the shadow page-table uses current 64-bit shadow code''s structure to simulate 32-bit guest''s 2-level page-table.

Fix PAE shadow on a machine with RAM above 4G on x86_64 xen. Currently, on a machine with RAM above 4G, we can not run 32bit VMX guest on x86_64 xen, the root cause is that the PAE page table PDPT must below 4G, this patch fixes this issue.

Hi Keir, this patch changes common code of xen hypervisor, but seems we have to, because current call to do_boot_vcpu is always from domains, however, for SMP VMX guest AP bring up, we need call it from xen hypervisor, so we''d like to split it. What''s your opinion? _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

We have tested the latest xen on VT platform with Intel 915/E8500 chipset. Here is the test summary: Issues: - Cannot boot Four VMX at same time on IA32 host - Cannot boot Windows XP SP1/SP2 on IA32e host - Create IA32-PAE VMX on IA32e host will make VMX kernel panic - Create IA32 VMX on IA32e host will make VMX hang - Destroying VMX with 4G memory may make xend hang on IA-32e IA-32: -

To avoid MSR save/restore at every VM exit/entry time, we restore the x86_64 specific MSRs at domain switch time if modified. In VMX domains, we modify those upon requests from the guests to that end. Note that IA32_EFER.LME and IA32_EFER.LMA are saved/restored by H/W on every VM exit. For the usual domains (i.e. dom0 and domU), those MSRs are not modified once set at initialization time, so we

The patch enables x86_32 PAE unmodified guests on 64-bit Xen when the hvm feature is present. We tested only Linux at this point, and we''ll improve the functionality as we test other guests. The SVM needs the equivalent changes to the vmc.c to get this functionality working, but this patch does not break the build. Signed-off-by: Jun Nakajima <jun.nakajima@intel.com>
