is_mapped() in xc_domain_save()
Hi all,
I think I have a pretty good grasp on domain save/migration code in
xc_domain_save() in Xen 3.2.x, except for the what the is_mapped()
macro is doing in following:
/* Hypercall interfaces operate in PFNs for HVM guests
* and MFNs for PV guests */
if ( hvm )
pfn_type[batch] = n;
else
pfn_type[batch] = pfn_to_mfn(n);
if ( !is_mapped(pfn_type[batch]) )
{

where is tools\xcutils\xc_save used?
I want to add some parameters when vm is migrated. As I can see , vmm will
use xc_domain_save(tools\libxc\Xc_domain_save.c) function ,and the main
function of xc_save.c is responsible for inputting parameters.
so I just want to know which function will use this executable file.
Thanks

[PATCH 0 of 4] Support for VM generation ID save/restore and migrate
This patch series adds support for preservation of the VM generation ID buffer
address in xenstore across save/restore and migrate, and also code to
increment the value in all cases except for migration.
Patch 1 modifies the guest ro and rw node creation to an open coding style

[PATCH 0 of 2] Support for VM generation ID save/restore and migrate
This patch series adds support for preservation of the VM generation ID
buffer address in xenstore across save/restore and migrate, and also
code to increment the value in all cases except for migration.
The vast majority of the code is in second patch. The first patch
merely changes the xenstore key name used by hvmloader to store the
buffer address.

How to get the checkpoint size in remus code?
Hi,
I''m doing my master research and I need to adapt remus code. Now... I wanna
get the checkpoint size (memory + disk) on each period. Does someone know
what function does this? I think some *fd *object''s function in remus code
could just get the memory size.
Does someone help me?
Thanks

[PATCH] libxl: pass debug flag down to libxl_domain_suspend
...daf4c52ba46677de
# Parent 12455da211d4e841692b2374086356a87eb74ff7
libxl: pass debug flag down to libxl_domain_suspend
libxl_domain_suspend is already prepared to handle LIBXL_SUSPEND_DEBUG,
and xl migrate handles the -d switch as well. Pass this flag down to
libxl_domain_suspend, so that finally xc_domain_save can dump huge
amount of debug data to stdout.
Update xl.5 and help text output.

how to change checkpoint interval
Hi guys,
In my research, I want to change checkpoint interval during remus running.
I think that the checkpoint_settimer function (declared in libcheckpoint.c)
can do that I need.
But I would like to call a checkpoint_settimer in xc_domain_save.c. Then I
created a checkpoint_settimer*2* into xc_domain_save.c and this doesn''t
work coz probably the timer_settime function there.
Then I started to search the error or where I change the checkpoint
interval. After I just changed one line in checkpoint.c:

[PATCH 0 of 6] Add support for a VM generation ID virtual device (v2)
The following is a revised patch series to add support for a

"VM_Gen_Counter".
- It must also include a _DDN of "VM_Gen_Counter".
- It must contain a _HID object but no particular value is
required.

[RFC][PATCH] Kemari v1.0 released
Hi,
I would like to announce the first release of Kemari, an open-source
virtual machine synchronization mechanism for fault tolerance.
It offers a feasible approach to fault tolerance that does not
require the use of specific hardware or modification of applications/OS.
Kemari aims to keep VMs transparently running in times of hardware
failures. It transfers the state of the primary VM to the

Hello,
Is is possible during a live migration (inside xc_domain_save.c) to
get a pointer a page as it passes through the live migration process?
I would like to look at the flags field in struct page.
