I noted a possible problem restoring a machine. In xc_domain_restore (xc_domain_restore.c) if it''s not the last checkpoint we set O_NONBLOCK flag (search for fcntl) that we can call pagebuf_get or just load other pages (see following "goto loadpages;" line). Now we could ending up calling xc_tmem_restore/xc_tmem_restore_extra (xc_tmem.c) which ca...

Hi there, We are using latest version of XCP on 6 hosts. While issuing VM.start or VM.start_on xmlrpc functional call , it says : {''Status'': ''Failure'', ''ErrorDescription'': [''SESSION_INVALID'', ''OpaqueRef:cfb6df14-387d-40a1-cc27-d5962cba7712'']} However if I put VM.start in a loop maybe after

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 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
