[libvirt] Supporting vhost-net and macvtap in libvirt for QEMU

by Anthony Liguori

Disclaimer: I am neither an SR-IOV nor a vhost-net expert, but I've CC'd people that are who can throw tomatoes at me for getting bits wrong :-) I wanted to start a discussion about supporting vhost-net in libvirt. vhost-net has not yet been merged into qemu but I expect it will be soon so it's a good time to start this discussion. There are two modes worth supporting for vhost-net in libvirt. The first mode is where vhost-net backs to a tun/tap device. This is behaves in very much the same way that -net tap behaves in qemu today. Basically, the difference is that the virtio backend is in the kernel instead of in qemu so there should be some performance improvement. Current, libvirt invokes qemu with -net tap,fd=X where X is an already open fd to a tun/tap device. I suspect that after we merge vhost-net, libvirt could support vhost-net in this mode by just doing -net vhost,fd=X. I think the only real question for libvirt is whether to provide a user visible switch to use vhost or to just always use vhost when it's available and it makes sense. Personally, I think the later makes sense. The more interesting invocation of vhost-net though is one where the vhost-net device backs directly to a physical network card. In this mode, vhost should get considerably better performance than the current implementation. I don't know the syntax yet, but I think it's reasonable to assume that it will look something like -net tap,dev=eth0. The effect will be that eth0 is dedicated to the guest. On most modern systems, there is a small number of network devices so this model is not all that useful except when dealing with SR-IOV adapters. In that case, each physical device can be exposed as many virtual devices (VFs). There are a few restrictions here though. The biggest is that currently, you can only change the number of VFs by reloading a kernel module so it's really a parameter that must be set at startup time. I think there are a few ways libvirt could support vhost-net in this second mode. The simplest would be to introduce a new tag similar to <source network='br0'>. In fact, if you probed the device type for the network parameter, you could probably do something like <source network='eth0'> and have it Just Work. Another model would be to have libvirt see an SR-IOV adapter as a network pool whereas it handled all of the VF management. Considering how inflexible SR-IOV is today, I'm not sure whether this is the best model. Has anyone put any more thought into this problem or how this should be modeled in libvirt? Michael, could you share your current thinking for -net syntax? -- Regards, Anthony Liguori

[libvirt] [PATCH 0/4] Multiple problems with saving to block devices

by Daniel P. Berrange

This patch series makes it possible to save to a block device, instead of a plain file. There were multiple problems - WHen save failed, we might de-reference a NULL pointer - When save failed, we unlinked the device node !! - The approach of using >> to append, doesn't work with block devices - CGroups was blocking QEMU access to the block device when enabled One remaining problem is not in libvirt, but rather QEMU. The QEMU exec: based migration often fails to detect failure of the command and will thus hang forever attempting a migration that'll never succeed! Fortunately you can now work around this in libvirt using the virsh domjobabort command

[libvirt] [PATCHv4 00/51] another round of snapshot patches

by Eric Blake

I think I've addressed most findings from round 3 - by implementing the ability to redefine a snapshot, it becomes possible to restore snapshot hierarchy when recreating a transient domain by the same name. New goodies in this round: several bug fixes, add virsh snapshot-edit, drop undefine --snapshots-full (you can only remove snapshot metadata on undefine). I tested as I went, but this went through so many rebases that there may be some nasties that snuck in; but I wanted to get this posted now. I also know that I'm missing at least one major feature requested in the v3 review: namely, transient domains _should_ auto-remove snapshot metadata files when they halt, but right now aren't doing that. v3 was at: https://www.redhat.com/archives/libvir-list/2011-August/msg01132.html Also available here: git fetch git://repo.or.cz/libvirt/ericb.git snapshot or browse online at: http://repo.or.cz/w/libvirt/ericb.git/shortlog/refs/heads/snapshot I'm also trying to group things by several bugzilla related to various patches (looks like I still need to create a few): Eric Blake (51): https://bugzilla.redhat.com/show_bug.cgi?id=674537 snapshot: fix corner case on OOM during creation https://bugzilla.redhat.com/show_bug.cgi?id=733762 snapshot: better events when starting paused snapshot: fine-tune ability to start paused snapshot: expose --running and --paused in virsh snapshot: fine-tune qemu saved images starting paused snapshot: improve reverting to qemu paused snapshots snapshot: properly revert qemu to offline snapshots snapshot: fine-tune qemu snapshot revert states no bug filed yet... should be one about no stale metadata snapshot: allow deletion of just snapshot metadata snapshot: add snapshot-list --parent to virsh https://bugzilla.redhat.com/show_bug.cgi?id=733529 snapshot: speed up snapshot location snapshot: avoid crash when deleting qemu snapshots snapshot: track current domain across deletion of children snapshot: simplify acting on just children no bug filed yet... should be one about no stale metadata snapshot: let qemu discard only snapshot metadata snapshot: identify which snapshots have metadata snapshot: reflect new dumpxml and list options in virsh snapshot: identify qemu snapshot roots snapshot: allow recreation of metadata snapshot: refactor virsh snapshot creation snapshot: improve virsh snapshot-create, add snapshot-edit snapshot: add qemu snapshot creation without metadata no bug filed yet... should be one about snapshot migration snapshot: add qemu snapshot redefine support snapshot: prevent stranding snapshot data on domain destruction snapshot: teach virsh about new undefine flags snapshot: refactor some qemu code snapshot: cache qemu-img location snapshot: support new undefine flags in qemu snapshot: prevent migration from stranding snapshot data https://bugzilla.redhat.com/show_bug.cgi?id=638510 snapshot: refactor domain xml output snapshot: allow full domain xml in snapshot snapshot: correctly escape generated xml snapshot: update rng to support full domain in xml snapshot: store qemu domain details in xml snapshot: additions to domain xml for disks snapshot: reject transient disks where code is not ready snapshot: introduce new deletion flag snapshot: expose new delete flag in virsh snapshot: allow halting after snapshot snapshot: expose halt-after-creation in virsh snapshot: wire up new qemu monitor command snapshot: support extra state in snapshots snapshot: add <disks> to snapshot xml snapshot: also support disks by path snapshot: add virsh domblklist command snapshot: add flag for requesting disk snapshot snapshot: wire up disk-only flag to snapshot-create snapshot: reject unimplemented disk snapshot features snapshot: make it possible to audit external snapshot snapshot: wire up live qemu disk snapshots snapshot: use SELinux and lock manager with external snapshots docs/formatdomain.html.in | 40 +- docs/formatsnapshot.html.in | 269 ++- docs/schemas/Makefile.am | 1 + docs/schemas/domain.rng | 2555 +------------------- docs/schemas/{domain.rng => domaincommon.rng} | 32 +- docs/schemas/domainsnapshot.rng | 84 +- examples/domain-events/events-c/event-test.c | 37 +- include/libvirt/libvirt.h.in | 66 +- src/conf/domain_audit.c | 12 +- src/conf/domain_audit.h | 4 +- src/conf/domain_conf.c | 902 ++++++-- src/conf/domain_conf.h | 76 +- src/esx/esx_driver.c | 38 +- src/libvirt.c | 256 ++- src/libvirt_private.syms | 8 + src/libxl/libxl_conf.c | 5 + src/libxl/libxl_driver.c | 11 +- src/qemu/qemu_command.c | 5 + src/qemu/qemu_conf.h | 1 + src/qemu/qemu_driver.c | 1532 +++++++++--- src/qemu/qemu_hotplug.c | 18 +- src/qemu/qemu_migration.c | 48 +- src/qemu/qemu_migration.h | 2 -

[libvirt] [PATCH 0/8 v5] Summary on block IO throttle

by Lei Li

Changes since V3 - Use virTypedParameterPtr instead of specific struct in libvirt pulic API. - Relevant changes to remote driver, qemu driver, python support and virsh. Changes since V2 - Implement the Python binding support for setting blkio throttling. - Implement --current --live --config options support to unify the libvirt API. - Add changes in docs and tests. - Some changes suggested by Adam Litke, Eric Blake, Daniel P. Berrange. - Change the XML schema. - API name to virDomain{Set, Get}BlockIoTune. - Parameters changed to make them more self-explanatory. - virsh command name to blkdeviotune. - And other fixups. Changes since V1 - Implement the support to get the block io throttling for a device as read only connection - QMP/HMP. - Split virDomainBlockIoThrottle into two separate functions virDomainSetBlockIoThrottle - Set block I/O limits for a device - Requires a connection in 'write' mode. - Limits (info) structure passed as an input parameter virDomainGetBlockIoThrottle - Get the current block I/O limits for a device - Works on a read-only connection. - Current limits are written to the output parameter (reply). - And Other fixups suggested by Adam Litke, Daniel P. Berrange. - For dynamically allocate the blkiothrottle struct, I will fix it when implement --current --live --config options support. Today libvirt supports the cgroups blkio-controller, which handles proportional shares and throughput/iops limits on host block devices. blkio-controller does not support network file systems (NFS) or other QEMU remote block drivers (curl, Ceph/rbd, sheepdog) since they are not host block devices. QEMU I/O throttling works with all types of drive and can be applied independently to each drive attached to a guest and supports throughput/iops limits. To help add QEMU I/O throttling support to libvirt, we plan to complete it with add new API virDomain{Set, Get}BlockIoThrottle(), new command 'blkdeviotune' and Python bindings. Notes: Now all the planed features were implemented (#1#2 were implemented by Zhi Yong Wu), the previous comments were all fixed up too. And the qemu part patches have been accepted upstream and are expected to be part of the QEMU 1.1 release, git tree from Zhi Yong: http://repo.or.cz/w/qemu/kevin.git/shortlog/refs/heads/block 1) Enable the blkio throttling in xml when guest is starting up. Add blkio throttling in xml as follows: <disk type='file' device='disk'> ... <iotune> <total_bytes_sec>nnn</total_bytes_sec> ... </iotune> ... </disk> 2) Enable blkio throttling setting at guest running time. virsh blkdeviotune <domain> <device> [--total_bytes_sec<number>] [--read_bytes_sec<number>] \ [--write_bytes_sec<number>] [--total_iops_sec<number>] [--read_iops_sec<number>] [--write_iops_sec<number>] 3) The support to get the current block i/o throttling for a device - HMP/QMP. virsh blkiothrottle <domain> <device> total_bytes_sec: read_bytes_sec: write_bytes_sec: total_iops_sec: read_iops_sec: write_iops_sec: 4) Python binding support for setting blkio throttling. 5) --current --live --config options support to unify the libvirt API. virsh blkdeviotune <domain> <device> [--total_bytes_sec <number>] [--read_bytes_sec <number>] [--write_bytes_sec <number>] [--total_iops_sec <number>] [--read_iops_sec <number>] [--write_iops_sec <number>] [--config] [--live] [--current] daemon/remote.c | 108 +++++++ docs/formatdomain.html.in | 31 ++ docs/schemas/domaincommon.rng | 24 ++ include/libvirt/libvirt.h.in | 70 ++++ python/generator.py | 2 + python/libvirt-override-api.xml | 16 + python/libvirt-override.c | 179 +++++++++++ src/conf/domain_conf.c | 101 ++++++- src/conf/domain_conf.h | 12 + src/driver.h | 20 ++ src/libvirt.c | 145 +++++++++ src/libvirt_public.syms | 2 + src/qemu/qemu_command.c | 33 ++ src/qemu/qemu_driver.c | 338 ++++++++++++++++++++ src/qemu/qemu_monitor.c | 36 ++ src/qemu/qemu_monitor.h | 22 ++ src/qemu/qemu_monitor_json.c | 185 +++++++++++ src/qemu/qemu_monitor_json.h | 10 + src/qemu/qemu_monitor_text.c | 164 ++++++++++ src/qemu/qemu_monitor_text.h | 10 + src/remote/remote_driver.c | 96 ++++++ src/remote/remote_protocol.x | 26 ++- src/remote_protocol-structs | 24 ++ src/util/xml.h | 2 + .../qemuxml2argv-blkdeviotune.args | 4 + .../qemuxml2argvdata/qemuxml2argv-blkdeviotune.xml | 37 +++ tests/qemuxml2argvtest.c | 1 + tests/qemuxml2xmltest.c | 1 + tools/virsh.c | 240 ++++++++++++++ tools/virsh.pod | 23 ++ 30 files changed, 1958 insertions(+), 4 deletions(-) -- Lei

[libvirt] [PATCH] Change security driver APIs to use virDomainDefPtr instead of virDomainObjPtr

by Daniel P. Berrange

From: "Daniel P. Berrange" <berrange(a)redhat.com> When sVirt is integrated with the LXC driver, it will be neccessary to invoke the security driver APIs using only a virDomainDefPtr since the lxc_container.c code has no virDomainObjPtr available. Aside from two functions which want obj->pid, every bit of the security driver code only touches obj->def. So we don't need to pass a virDomainObjPtr into the security drivers, a virDomainDefPtr is sufficient. Two functions also gain a 'pid_t pid' argument. * src/qemu/qemu_driver.c, src/qemu/qemu_hotplug.c, src/qemu/qemu_migration.c, src/qemu/qemu_process.c, src/security/security_apparmor.c, src/security/security_dac.c, src/security/security_driver.h, src/security/security_manager.c, src/security/security_manager.h, src/security/security_nop.c, src/security/security_selinux.c, src/security/security_stack.c: Change all security APIs to use a virDomainDefPtr instead of virDomainObjPtr --- src/qemu/qemu_driver.c | 10 +- src/qemu/qemu_hotplug.c | 28 ++-- src/qemu/qemu_migration.c | 12 +- src/qemu/qemu_process.c | 24 ++-- src/security/security_apparmor.c | 136 ++++++++++---------- src/security/security_dac.c | 91 +++++++------- src/security/security_driver.h | 36 +++--- src/security/security_manager.c | 40 +++--- src/security/security_manager.h | 36 +++--- src/security/security_nop.c | 36 +++--- src/security/security_selinux.c | 260 +++++++++++++++++++------------------- src/security/security_stack.c | 44 ++++--- 12 files changed, 381 insertions(+), 372 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 6cfdd1d..6e001ce 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -3096,7 +3096,7 @@ qemuDomainScreenshot(virDomainPtr dom, } unlink_tmp = true;

[libvirt] [PATCH 0/2] Introduce two new virsh commands

by Osier Yang

These two patches is to introduce two new virsh commands, one is eject-media, which is to eject media from CD or floppy drive, the other is insert-media, which is to insert media into CD or floppy drive. There are commands existed can be used to eject/insert media, such as "update-device", but it's not quite easy to use. That's the original intention of these patches. Both of the two commands only allow to operate on CDROM or floppy disk. [PATCH 1/2] virsh: Introduce two new commands to insert or eject media [PATCH 2/2] doc: Add docs for two new introduced commands Regards Osier
