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 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

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 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''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, 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

This patch series adds support for network buffering in the Remus codebase in libxl. Changes in V3: [1/5] Fix redundant checks in configure scripts (based on Ian Campbell''s suggestions) [2/5] Introduce locking in the script, during IFB setup. Add xenstore paths used by netbuf scripts to xenstore-paths.markdown [3/5] Hotplug scripts setup/teardown invocations are now

This patch series restores the use of superpages when restoring or migrating a VM, while retaining efficient batching of 4k pages when superpages are not appropriate or available.

Hi all, I need to make some modifications to xc_save and xc_restore to Xen 3.0.3 for research purposes. In order to avoid to recompile all the xen source at each modification I do to these binaries, I thougt to substitute the version of this two binaries which is installed in /usr/lib64/xen/bin, with a version I compile myself from the Xen source code tarball. The problem is that after doing

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 currently
