https://bugzilla.redhat.com/show_bug.cgi?id=1694166 A work in progress, but I'm sending it now to get the XML bikesh^Wdiscussion out of the way. TODO: * documentation (due to the requirement of shared memory and therefore a <numa> topology specification, this probably deserves a separate article on https://libvirt.org/kbase.html ) * validation - refuse unsupported combinations and block migration * remove a few hardcoded values * figure out the binary path from qemu interop config * leave queue-size and cache-size on their default values or expose them in XML * use FD passing for vhost-user-fs device as well * clean up the code Tested with: commit 320000e72ec0613e164ce9608d865396fb2da278 Author: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx> Date: Wed Oct 30 14:17:18 2019 +0100 Merge tag 'iommu-fixes-v5.4-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu and commit d3d2efbb0e37494708dde359a9d0f492f84833e8 Author: Dr. David Alan Gilbert <dgilbert@xxxxxxxxxx> CommitDate: 2019-10-24 11:50:55 +0100 virtio-fs: Allow mapping of meta data version table from https://gitlab.com/virtio-fs/qemu/tree/virtio-fs-dev git fetch https://gitlab.com/virtio-fs/qemu.git virtio-fs-dev (not yet merged upstream) Ján Tomko (9): qemu: address: take fsdriver type into account qemu: cmdline: take fsdriver into account qemu: add QEMU_CAPS_VHOST_USER_FS wip: tests: add xml2xml tests for virtio-fs wip: add XML -> ARGV tests for virtio-fs conf: qemu: add virtio-fs fsdriver type qemu: pass private data to qemuBuildFilesystemCommandLine wip: start virtiofsd wip: build vhost-user-fs device command line docs/schemas/domaincommon.rng | 1 + src/conf/domain_conf.c | 1 + src/conf/domain_conf.h | 2 + src/qemu/qemu_capabilities.c | 4 + src/qemu/qemu_capabilities.h | 3 + src/qemu/qemu_command.c | 67 +++++- src/qemu/qemu_domain.c | 4 + src/qemu/qemu_domain_address.c | 35 +++- src/qemu/qemu_extdevice.c | 191 ++++++++++++++++++ ...vhost-user-fs-fd-memory.x86_64-latest.args | 38 ++++ .../vhost-user-fs-fd-memory.xml | 38 ++++ ...vhost-user-fs-hugepages.x86_64-latest.args | 42 ++++ .../vhost-user-fs-hugepages.xml | 67 ++++++ tests/qemuxml2argvtest.c | 9 + .../vhost-user-fs-fd-memory.x86_64-latest.xml | 1 + .../vhost-user-fs-hugepages.x86_64-latest.xml | 1 + tests/qemuxml2xmltest.c | 3 + 17 files changed, 493 insertions(+), 14 deletions(-) create mode 100644 tests/qemuxml2argvdata/vhost-user-fs-fd-memory.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/vhost-user-fs-fd-memory.xml create mode 100644 tests/qemuxml2argvdata/vhost-user-fs-hugepages.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/vhost-user-fs-hugepages.xml create mode 120000 tests/qemuxml2xmloutdata/vhost-user-fs-fd-memory.x86_64-latest.xml create mode 120000 tests/qemuxml2xmloutdata/vhost-user-fs-hugepages.x86_64-latest.xml -- 2.21.0 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
