Virtio-fs is a shared file system that enables sharing a directory between host and guest VMs. It takes advantage of the locality of virtual machines and the hypervisor to get a higher throughput than the 9p remote file system protocol.
build-order: 1. cluster 2. guest-common 3. docs 4. qemu-server 5. manager I did not get virtiofsd to run with run_command without creating zombie processes after stutdown. So I replaced run_command with exec for now. Maybe someone can find out why this happens. notes to v16: * "Make sure the directory exists." banner still exists as checking for the directory to exist on a different node is difficult changes in v16: * find_on_current_node: fixed undefined values error * die if the directory id does not exist * die if there is no directory mapping for the node * add hint for directory mapping in virtiofs edit window * minor changes -> see individual patches changes in v15: * removed announce-submounts option altogether and always set it for virtiofsd. * added die if both memory hotplug and virtiofs are enabled * added fstab entry example in the docs * assert_valid_map_list: only run assert_valid for the mappings on the current node changes in v14: * disallow commas and equal signs in path until the path can be quoted in property strings * addressed style nits and improved formatting * use max_virtiofs() in check_vm_create_dir_perm * removed unnecessary checks after parse_property_string * find_on_current_node returns only one entry * improved docs * added missing imports/uses changes in v13: * removed acl/xattr attributes in node config * renamed acl/xattr in virtiofs qemu config to expose-acl/expose-xattr * renamed submounts in node config to announce-submounts * the "disable snapshot (with RAM) and hibernate with virtio-fs devices" patch now uses the check_non_migratable_resources function * rewritten the part about announce-submounts in pve-docs patch Changes in v12: * rebase to master as most patches could not be applied anymore Changes in v11: * made submounts option on by default in WebUI and section config * PVE::QemuServer::Virtiofs dependency removed in QemuServer/Memory.pm * Minor changes to function/variable names * Disable snapshots (with RAM) and hibernate due to incompatibility cluster: Markus Frank (1): add mapping/dir.cfg for resource mapping src/PVE/Cluster.pm | 1 + src/pmxcfs/status.c | 1 + 2 files changed, 2 insertions(+) guest-common: Markus Frank (1): add dir mapping section config src/Makefile | 1 + src/PVE/Mapping/Dir.pm | 198 +++++++++++++++++++++++++++++++++++++++++ 2 files changed, 199 insertions(+) create mode 100644 src/PVE/Mapping/Dir.pm docs: Markus Frank (1): add doc section for the shared filesystem virtio-fs qm.adoc | 102 ++++++++++++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 100 insertions(+), 2 deletions(-) qemu-server: Markus Frank (4): control: add virtiofsd as runtime dependency for qemu-server fix #1027: virtio-fs support migration: check_local_resources for virtiofs disable snapshot (with RAM) and hibernate with virtio-fs devices PVE/API2/Qemu.pm | 41 ++++++- PVE/QemuServer.pm | 42 ++++++- PVE/QemuServer/Makefile | 3 +- PVE/QemuServer/Memory.pm | 25 +++-- PVE/QemuServer/Virtiofs.pm | 209 +++++++++++++++++++++++++++++++++++ debian/control | 1 + test/MigrationTest/Shared.pm | 7 ++ 7 files changed, 315 insertions(+), 13 deletions(-) create mode 100644 PVE/QemuServer/Virtiofs.pm manager: Markus Frank (5): api: add resource map api endpoints for directories ui: add edit window for dir mappings ui: add resource mapping view for directories ui: form: add selector for directory mappings ui: add options to add virtio-fs to qemu config PVE/API2/Cluster/Mapping.pm | 7 + PVE/API2/Cluster/Mapping/Dir.pm | 308 ++++++++++++++++++++++++++++ PVE/API2/Cluster/Mapping/Makefile | 1 + www/manager6/Makefile | 4 + www/manager6/Utils.js | 1 + www/manager6/dc/Config.js | 10 + www/manager6/dc/DirMapView.js | 38 ++++ www/manager6/form/DirMapSelector.js | 63 ++++++ www/manager6/qemu/HardwareView.js | 19 ++ www/manager6/qemu/VirtiofsEdit.js | 143 +++++++++++++ www/manager6/window/DirMapEdit.js | 204 ++++++++++++++++++ 11 files changed, 798 insertions(+) create mode 100644 PVE/API2/Cluster/Mapping/Dir.pm create mode 100644 www/manager6/dc/DirMapView.js create mode 100644 www/manager6/form/DirMapSelector.js create mode 100644 www/manager6/qemu/VirtiofsEdit.js create mode 100644 www/manager6/window/DirMapEdit.js -- 2.39.5 _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
