similar to: Patch to remove ignored setting in VMCS for VMX domains ....

This patch removes the ignored "Unconditional I/O exiting" setting in VMCS for the vmx guest since "Use I/O bitmaps" setting is being used.

Hi Folks, I need some large chunk of physical memory, so I allocate it early using alloc_bootmem_low_pages and use it later (akin to bigphysarea patch). The trouble I am having is the following. Suppose the virtual address for the memory area is 0xc14d6000. After xen_create_contiguous_region call, I do a virt_to_bus and the bus address comes out to be 0x18000000. So far so good. However,

Hi Folks, I saw some references to the same problem in mailing list but no solution. I am running a DomU with PHYSDEV access. With fedora core 4, I just changed the inittab file to not start getty''s on tty1-6, and it worked (only ttyS0 is enabled). However, same trick didn''t do it for debian. I can boot into a shell if I put init=/bin/bash on kernel command line. However,

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

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

I recently realized that the original way of dealing with the DebugCtl MSR on VMX failed to make use of the dedicated guest VMCS field. This is being fixed with this patch. What is puzzling me to a certain degree is that while there is a guest VMCS field for this MSR, there''s no equivalent host load field, but there''s also no indication that the MSR would be cleared during a
