Entering freeze for libvirt-8.2.0
by Jiri Denemark 31 Mar '22

31 Mar '22

I have just tagged v8.2.0-rc1 in the repository and pushed signed tarballs and source RPMs to https://libvirt.org/sources/ Please give the release candidate some testing and in case you find a serious issue which should have a fix in the upcoming release, feel free to reply to this thread to make sure the issue is more visible. If you have not done so yet, please update NEWS.rst to document any significant change you made since the last release. Thanks, Jirka

[libvirt PATCH] fix documentation for sockets topology
by John Levon 30 Mar '22

30 Mar '22

From: John Levon <john.levon(a)nutanix.com> In 0895a0e, it was noted that the "sockets" value in the topology section of capabilities reflects not the number of sockets per NUMA node, not the total number. Unfortunately, the fix was applied to the wrong place: the domain XML format documentation, not that for the capabilities output. And, in fact, the domain XML interprets "sockets" as the total number, not a per-node value. Back out this change in favour of a note in the capabilities documentation instead.

[libvirt PATCH] qemu: Rename virDomainAsyncJobPhase{From,To}String
by Jiri Denemark 30 Mar '22

30 Mar '22

Recent refactor (v8.1.0-217-ga193f4bef6) generalized job related enums and functions by changing "qemu" prefix to "vir" and moving them to src/hypervisor/domain_job.[ch]. This was in most cases a good thing, but async job phases are driver specific and the corresponding functions remained in src/qemu/qemu_domainjob.[ch], but still their prefix was changed to "vir". Let's change it back to "qemu".

[libvirt PATCH] qemu: fix hotplug for multiqueue vdpa net device
by Jonathon Jongsma 30 Mar '22

30 Mar '22

While commit a5e659f0 removed the restriction against multiple queues for the vdpa net device, there were some missing pieces. Configuring a device statically and then starting the domain worked as expected, but hotplugging a device didn't have the expected multiqueue support enabled. Add the missing bits. Consider the following device xml: <interface type="vdpa"> <mac address="00:11:22:33:44:03" /> <source dev="/dev/vhost-vdpa-0" /> <model type="virtio" /> <driver queues='2' /> </interface> Without this patch, hotplugging the above XML description resulted in the following: {"execute":"netdev_add","arguments":{"type":"vhost-vdpa","vhostdev":"/dev/fdset/0","id":"hostnet1"},"id":"libvirt-392"} {"execute":"device_add","arguments":{"driver":"virtio-net-pci","netdev":"hostnet1","id":"net1","mac":"00:11:22:33:44:03","bus":"pci.5","addr":"0x0"},"id":"libvirt-393"} With the patch, hotplugging results in the following: {"execute":"netdev_add","arguments":{"type":"vhost-vdpa","vhostdev":"/dev/fdset/0","queues":2,"id":"hostnet1"},"id":"libvirt-392"} {"execute":"device_add","arguments":{"driver":"virtio-net-pci","mq":true,"vectors":6,"netdev":"hostnet1","id":"net1","mac":"00:11:22:33:44:03","bus":"pci.5","addr":"0x0"},"id":"libvirt-393"} Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=2024406 Signed-off-by: Jonathon Jongsma <jjongsma(a)redhat.com> --- src/qemu/qemu_command.c | 4 ++++ src/qemu/qemu_hotplug.c | 3 +++ tests/qemuxml2argvdata/net-vdpa-multiqueue.x86_64-latest.args | 2 +- 3 files changed, 8 insertions(+), 1 deletion(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 453891a725..f7f55b20ef 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -4346,6 +4346,10 @@ qemuBuildHostNetProps(virDomainNetDef *net, if (virJSONValueObjectAdd(&netprops, "s:type", "vhost-vdpa", NULL) < 0 || virJSONValueObjectAppendString(netprops, "vhostdev", vdpadev) < 0) return NULL; + + if (net->driver.virtio.queues > 1 && + virJSONValueObjectAppendNumberUlong(netprops, "queues", net->driver.virtio.queues) < 0) + return NULL; break; case VIR_DOMAIN_NET_TYPE_HOSTDEV: diff --git a/src/qemu/qemu_hotplug.c b/src/qemu/qemu_hotplug.c index 3d1bb1be2a..d9ba0b7abe 100644 --- a/src/qemu/qemu_hotplug.c +++ b/src/qemu/qemu_hotplug.c @@ -1386,6 +1386,9 @@ qemuDomainAttachNetDevice(virQEMUDriver *driver, break; case VIR_DOMAIN_NET_TYPE_VDPA: + queueSize = net->driver.virtio.queues; + if (!queueSize) + queueSize = 1; if (qemuDomainAdjustMaxMemLock(vm, false) < 0) goto cleanup; adjustmemlock = true; diff --git a/tests/qemuxml2argvdata/net-vdpa-multiqueue.x86_64-latest.args b/tests/qemuxml2argvdata/net-vdpa-multiqueue.x86_64-latest.args index 26ef666036..4cb805451a 100644 --- a/tests/qemuxml2argvdata/net-vdpa-multiqueue.x86_64-latest.args +++ b/tests/qemuxml2argvdata/net-vdpa-multiqueue.x86_64-latest.args @@ -29,7 +29,7 @@ XDG_CONFIG_HOME=/tmp/lib/domain--1-QEMUGuest1/.config \ -boot strict=on \ -device '{"driver":"piix3-usb-uhci","id":"usb","bus":"pci.0","addr":"0x1.0x2"}' \ -add-fd set=0,fd=1732,opaque=net0-vdpa \ --netdev vhost-vdpa,vhostdev=/dev/fdset/0,id=hostnet0 \ +-netdev vhost-vdpa,vhostdev=/dev/fdset/0,queues=2,id=hostnet0 \ -device '{"driver":"virtio-net-pci","mq":true,"vectors":6,"netdev":"hostnet0","id":"net0","mac":"52:54:00:95:db:c0","bus":"pci.0","addr":"0x2"}' \ -audiodev '{"id":"audio1","driver":"none"}' \ -sandbox on,obsolete=deny,elevateprivileges=deny,spawn=deny,resourcecontrol=deny \ -- 2.35.1

[PATCH] Introduce network-backed NVRAM
by Rohit Kumar 28 Mar '22

28 Mar '22

Libvirt domain XML allows only local filepaths to specify a NVRAM element. Since VMs can move across different hosts, it should be possibe to allocate NVRAM disks on network storage for uninturrupted access. This Patch extends the NVRAM disk elements to be described as virStorageSource* elements.
