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 in psuedo-physical map -- set bit ** in to_fix since we must send this page in last_iter ** unless its sent sooner anyhow, or it never enters ** pseudo-physical map (e...

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.

...re used to handle broken page wrt migration. Generally there are 2 cases: the broken page occur before migration, and the broken page occur during migration. Patch 01 handles the case that broken page occurred before migration: At the sender, the broken page would not be copied to target while its pfn_type and pfn number would be transferred to target, so that at target, it would set p2m as p2m_ram_broken for broken page. Patch 02 handles the case that broken page occurred during migration: At the sender, marks the broken page to dirty bitmap, so that at copypages stage of migration, its pfn_type an...

The following dump-core patches changes its format into ELF, adds PFN-GMFN table, HVM support, and adds experimental IA64 support. - ELF format Program header and note section are adopted. - HVM domain support To know the memory area to dump, XENMEM_set_memory_map is added. XENMEM_memory_map hypercall is for current domain, so new one is created. and hvm domain builder tell xen its

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 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.

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
