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 VMREAD/VMWRITE bitmap instead of xenheap. Changes from v1 to v2: - Use domain_page_map_to_mfn() instead of virt_to_mfn() to get the machine frame. - Address othe...

...380 G7 with Xeon X5675 and 96 GB, running half a dozen smallish VMs. Hypervisor and all VMs have kernel 2.6.32-754.2.1.el6.x86_64. Around the time the VMs must have gone down, there are quite a few error messages like the following in the system log: Aug 16 03:10:13 hyper-7 kernel: [265397.382552] vmwrite error: reg 6000 value fffffffffffffff7 (err -9) Aug 16 03:10:13 hyper-7 kernel: [265397.421372] Pid: 9375, comm: qemu-kvm Not tainted 2.6.32-754.2.1.el6.x86_64 #1 Aug 16 03:10:13 hyper-7 kernel: [265397.464985] Call Trace: Aug 16 03:10:13 hyper-7 kernel: [265397.481530] [<ffffffffa0532a9c>]...

Hi all, Can Xen hypervisor modify HVM domU's Shadow page table, under the dom0's context, like trapped from dom0's hypercall? I think it have to call 2 functions at least: guest_walk_tables() and flush_tlb_all(). Can these 2 functions called in dom0's context? In my test, if hypervisor tries to modify HVM's shadow page table, it will bring down the whole system. I am not

Hi, I know this may be very basic question but I need some help . Actually I installed VM using the Xen Administrative console. Now I need to change the configuration file as I need to passthrough (using the pci-hide) a SCSI contoller from Dom0 to DomU. But I couldnot find the configuration file. Where can I find the Configuration file for this DomU? Actually I added the

Hi all, Please can anybody explain how communication(direct or indirect) happens between xen and guest os(windows) in full virtualization mode. Both from VMM to guest and from guest to VMM.
