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]) ) { /* ** not...

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.

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 and cleans up some extraneous node creation. Patch 2 modifies creation of the hvmloader key in xenstore and adds

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.

The first patch modifies creation of the hvmloader key in xenstore and adds creation of a new read/write hvmloader/generation-id-addr key. The second patch changes hvmloader to use the new key (as

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 _______________________________________________ Xen-devel mailing list

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: from: checkpoint_settim...

The following is a revised patch series to add support for a VM generation ID virtual device for HVM guests. The basic requirements of this device are as follows: - It must be exposed somewhere in ACPI namespace with a _CID of "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. - It must

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?
