Hello, For our research we are trying to come up with a Virtual - passthrough model of device drivers in  PV guests. We are looking for 2 separate implementations : 1 for transmitting and the other for receiving the packets in the guest OS. We are relying on IOMMU to ensure isolation. We need to add  these new hypercalls for communication between the guest device driver and the hypervisor. The

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

Hi I need to use hypercalls from HVM domain (e.g. HYPERVISOR_add_to_physmap). However, it does not work when I am trying to invoke it from HVM Linux guest. Basically, I don''t see that anything happens on hypervisor''s side. I also grep''ed the guest code for ''vmmcall''/''vmcall'' and did not find anything. Is it possible to do it at all?

While looking at the origin of very frequently executed hypercalls (as usual, kernel builds are what''s being measured), I realized that the high page accessor functions in Linux would be good candidates to handle in the hypervisor - clearing or copying to/from a high page is a pretty frequent operation (provided there''s enough memory). However, the measured results

Hi, I am running xen-hypervisor over qemu. Now while running domU I want to write on an IO port, which I''ll be handling inside Qemu. Basically, this is a communication mechanism for me to communicate with qemu. I am writing on port number ''0x378'' as a root user using "outl" function. But when I run this code in domU, it does not reach qemu. So my question is:

I am learning xen's memory management recently. I find most docs is how to use the hypercall related memory management. Can somesome tell me where is the implementation of the them in the xen source. Or some docs explaining it will be ideal. 年少不惧江湖老，放歌四海任逍遥。未解前路多少事，欲与青天试比高。 _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org

I am now testing XEN live migration on two physical hosts with XEN 4.0.1 pvops Ubuntu 10.10 (2.6.35-22). Host A also acts as a NFS server, and Host B acts as a NFS client. When I migrate a guest domain from B to A. The ssh connection experiences a downtime of about 1 minute (the terminal does not react to the keyboard input till about 1 minute later). However, the "sudo xm console" does

Hi, Is there any way asterisk can detect if the outgoing call is being received by a user or it has been forwarded to his voicemail. Actually my requirement is to proceed only if user picks up the phone otherwise to hangup as soon as the call goes to voicemail. Is there anyway to do this? Thanks in advance.

This group of patches removes all DPRINT from hv_vmbus.ko. It is divided in several patches due to size. All DPRINT calls have been removed, and where needed have been replaced with pr_XX native calls. Many debug DPRINT calls have been removed outright. The amount of clutter this driver prints has been significantly reduced. Signed-off-by: Hank Janssen <hjanssen at microsoft.com>

Hi, 1) From the code it appears that there is no common entry/exit point for the hypervisor calls. Wanted to confirm if this is right? 2) Also is there a per-domain flag to indicate that the hypervisor call is in progress in a particular domain?
