[pve-devel] [PATCH cluster/guest-common/docs/qemu-server/manager v15 0/12] virtiofs

[Markus Frank <m.frank@proxmox.com>]

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.

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
* see individual patches

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
