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

Sorry that I forgot writing the title at last mail. ----------- Hi men, I found that there is a configration: Processor type and features -> Paravirtualized guest support -> Xen guest support when compiling linux kernel. What dose this mean? If I select this, can the kernel compiled run as a paravirtualized guest on Xen? I did this, but the kernel works just as normal. Thanks, Wu

Hi men, When installing Xen, it builds a linux guest kernel of 2.6.18 as dom0, which does not support my network card. While 2.6.27 supports my card. So what should I do now?

Hi men, I compiled and installed Xen 3.3.0 on Fedora 8, and it worked fine. However, after installing virt-manager, it goes wrong: # xm Traceback (most recent call last): File "/usr/sbin/xm", line 8, in <module> from xen.xm import main File "//usr/lib/python/xen/xm/main.py", line 52, in <module> from xen.xm import console File

Hi, I am reading shadow memory code in Xen 3.3.0, and have a question. In HVM guest, if a process writes a non-existing page, what happens: First, page fault occurs, and traps into Xen. Xen finds out that that page doesn''t exist in guest page table, so go back to guest. The guest fixes this fault in its page table, and writes that page again. Because that page doesn''t exist in

Hello, I am studing Xen hypercall now. I found that hypercall is invoked via hypercall_page, which is only filled with (in no-hypervisor-kernel-mode ): mov $i, %eax int $0x82 ret Why not invoked the hypercall directly by "int $0x82" ? What''s the advantage of using hypercall_page? Thanks, Wu _______________________________________________ Xen-devel mailing list
