In thecurrent implementation, bhyve(8) creates a UNIX domain socket that isused by bhyvectl(8) to send a request to save a snapshot (andoptionally exit after the snapshot has been taken). A snapshotcurrently consists of two files: the first holds a copy of guest RAM,and the second file holds other guest state such as vCPU registervalues and device model state.To resume a guest, bhyve(8) must be started with a matching pair ofcommand line arguments to instantiate the same set of device models aswell as a pointer to the saved snapshot.While the current implementation is useful for several uses cases, ithas a few limitations. The file format for saving the guest state istied to the ABI of internal bhyve structures and is notself-describing (in that it does not communicate the set of devicemodels present in the system). In addition, the state saved for somedevice models closely matches the internal data structures which mightprove a challenge for compatibility of snapshot files across a rangeof bhyve versions. The file format also does not currently supportversioning of individual chunks of state. As a result, the currentfile format is not a fixed binary format and future revisions to saveand restore will break binary compatiblity of snapshot files. Thegoal is to move to a more flexible format that adds versioning,etc. and at that point to commit to providing a reasonable level ofcompatibility. As a result, the current implementation is not enabledby default. It can be enabled via the WITH_BHYVE_SNAPSHOT=yes optionfor userland builds, and the kernel option BHYVE_SHAPSHOT.Submitted by: Mihai Tiganus, Flavius Anton, Darius MihaiSubmitted by: Elena Mihailescu, Mihai Carabas, Sergiu WeiszRelnotes: yesSponsored by: University Politehnica of BucharestSponsored by: Matthew Grooms (student scholarships)Sponsored by: iXsystemsDifferential Revision: https://reviews.freebsd.org/D19495 List of files: /src/usr.sbin/bhyvectl/Makefile Tue, 05 May 2020 00:02:04 +0000 John Baldwin <jhb@FreeBSD.org> http://opengrok.net:8080/history/src/usr.sbin/bhyvectl/Makefile#1c4ee7dfb8affed302171232b0f612e6bcba3c10 bhyvectl: Prepare to add arm64 supportMove MD code into a separate directory and add a simple interface whichlets the MD bits register options and handle them.No functional change intended.Reviewed by: jhbSponsored by: Innovate UKDifferential Revision: https://reviews.freebsd.org/D44932 List of files: /src/usr.sbin/bhyvectl/Makefile Wed, 01 May 2024 12:31:00 +0000 Mark Johnston <markj@FreeBSD.org> http://opengrok.net:8080/history/src/usr.sbin/bhyvectl/Makefile#d0b2dbfa0ecf2bbc9709efc5e20baf8e4b44bbbf Remove $FreeBSD$: one-line sh patternRemove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/ List of files: /src/usr.sbin/bhyvectl/Makefile Wed, 16 Aug 2023 17:55:03 +0000 Warner Losh <imp@FreeBSD.org> http://opengrok.net:8080/history/src/usr.sbin/bhyvectl/Makefile#3f5d875a27318a909f23a2b7463c4b2d963085df bhyvectl: Address compiler warnings and bump WARNSAvoid unaligned accesses in cpu_vendor_intel() and address a few othernits.

However the address range where devmem is mapped may be changedby the guest at runtime (e.g. by reprogramming a PCI BAR). Also devmem isusually mapped RO or RW as compared to RWX mappings for sysmem.Each devmem segment is named (e.g. "bootrom") and this name is used tocreate a device node for the devmem segment (e.g. /dev/vmm/testvm.bootrom).The device node supports mmap(2) and this decouples the host mapping ofdevmem from its mapping in the guest address space (which can change).Reviewed by: tychonDiscussed with: grehanDifferential Revision: https://reviews.freebsd.org/D2762MFC after: 4 weeks List of files: /src/usr.sbin/bhyvectl/Makefile Thu, 18 Jun 2015 06:00:17 +0000 Neel Natu <neel@FreeBSD.org> http://opengrok.net:8080/history/src/usr.sbin/bhyvectl/Makefile#7757a1b4dc60696d9a95137ee0a2accd4ee680f4 Merge from head List of files: /src/usr.sbin/bhyvectl/Makefile Sun, 03 May 2015 19:30:11 +0000 Baptiste Daroussin <bapt@FreeBSD.org> http://opengrok.net:8080/history/src/usr.sbin/bhyvectl/Makefile#5d0b9042a14c9b09bbd9efddb6ea6503e5286d55 bhyvectl does not need to link to libutil List of files: /src/usr.sbin/bhyvectl/Makefile Thu, 09 Apr 2015 21:39:58 +0000 Baptiste Daroussin <bapt@FreeBSD.org> http://opengrok.net:8080/history/src/usr.sbin/bhyvectl/Makefile#c2e2d02cbefeab0ff2fa6b33c4bba5bb4dbd234a Make FreeBSD-bhyve an indivual package List of files: /src/usr.sbin/bhyvectl/Makefile Thu, 05 Mar 2015 07:30:48 +0000 Baptiste Daroussin <bapt@FreeBSD.org>
