Grant references for the xenstore and xenconsole shared pages exist, but currently only xenstore uses these references. Change the xenconsole daemon to prefer using the grant reference over map_foreign_range when mapping the shared console ring. This allows xenconsoled to be run in a domain other than dom0 if set up correctly - for libxl, the xenstore path /tool/xenconsoled/domid specifies the

Hi: I wanna domU to map dom0''s page, so that these two domain can receive/send data between them in the future. But when I run my code , it told me that "Could not open grant table interface(22=invalid argument)". Can anybody know what the problem is ? Thanks .

Hi, I need to use the grant table mechanism, but I can''t find any example regarding how to do it. Could you please provide some examples?

This patch series introduces the shared ring used by the front-end to pass request descriptors to tapdisk, as well as responses from tapdisk to the front-end. Requests from this ring end up in tapdisk''s standard request queue. When the tapback daemon detects that the front-end tries to connect to the back-end, it spawns a tapdisk and tells it to connect to the shared ring. The shared

Hi, Header says: /* * Unmaps the @count pages starting at @start_address, which were mapped by a * call to xc_gntshr_share_*. Never logs. */ int xc_gntshr_munmap(xc_gntshr *xcg, void *start_address, uint32_t count); But implementation calls: static int linux_gntshr_munmap(xc_gntshr *xcg, xc_osdep_handle h, void *start_address, uint32_t count) { return

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -

Hi all, this is the long awaited patch series to add xen device model support in qemu; the main author is Anthony Perard. Developing this series we tried to come up with the cleanest possible solution from the qemu point of view, limiting the amount of changes to common code as much as possible. The end result still requires a couple of hooks in piix_pci but overall the impact should be very

Hi , I am using ubuntu host machine and KVM is present as guest in that machine.Two virtual machines are there.I am using Python binding to query on the hypervisor and extract the VM related information.I like to print memory stat of the VM like SWAP_IN , SWAP_OUT,free memory, mem cached etc.So, the code, I have written for this, is : #!/usr/local/bin/python import libvirt import sys conn =

Update kernel watch API to pass the array of watch arguments to the callback instead of just passing the node. This allows us to extend watches to have additional arguments (like domids).

Legacy (non-pvops) gntdev drivers may require this operation to be performed when the number of grants intended to be used simultaneously exceeds a certain driver specific default limit, and qemu''s qdisk driver is an example of needing to do so.

In a virtualized environment, virtual machines will time share the system with each other and with other processes running on the host system. Therefore, a VM's virtual CPUs (VCPUs) will be executing on the host's physical CPUs (pcpus) for only some portion of time. The VMI exposes a paravirtual view of time to the guest operating systems so that they may operate more effectively in a

This patch enables the following: a) Initializes the Intel MIC X100 PCIe devices. b) Boots and shuts down the card via sysfs entries. c) Allocates and maps a device page for communication with the card driver and updates the device page address via scratchpad registers. d) Provides sysfs entries for family, stepping, state, shutdown status, kernel command line, IP address, ramdisk and log buffer
