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. 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.

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

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 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

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 call read_extract (xc_private.c)

Populate-on-demand: Check pages being returned by the balloon driver This patch series is the second result of my work last summer on decreasing fragmentation of superpages in a guests'' p2m when using populate-on-demand. This patch series is against 4.1; I''m posting it to get feedback on the viability of getting a ported version of this patch into 4.2. As with the previous

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 -
