Feature proposal: Add page-per-vq flag to the 'driver' element of virtio devices
by Gavi Teitz 19 Apr '21

19 Apr '21

Hi, The page-per-vq flag is important for vdpa with vhost-user performance [1]. Currently there is no way in libvirt to set it in the xml page-per-vq except with qemu args, like so: <devices> <interface type='vhostuser'> <mac address='fa:16:3e:92:6d:79'/> <source type='unix' path='/var/lib/vhost_sockets/sock7f9a971a-cf3' mode='server'/> <model type='virtio'/> <driver queues='4' rx_queue_size='512' tx_queue_size='512'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> </devices> <qemu:commandline> <qemu:arg value='-set'/> <qemu:arg value='device.net0.page-per-vq=on'/> </qemu:commandline> However, this is not an approach which can be used for hotplug devices, as qemu:commandline arguments cannot be used for them, and is therefore not suitable for production. We propose to add the flag to the ' driver' element of virtio devices, as this is an attribute related to the virtio transport [2]. This will enable configuring virtio devices with the page-per-vq flag without relying on qemu:commandline arguments. Are there any issues that would prevent this feature from being accepted? Thanks, Gavi [1] - http://doc.dpdk.org/guides/sample_app_ug/vdpa.html - look for page-per-vq [2] - https://libvirt.org/formatdomain.html#virtio-related-options

[PATCH] lxc: Format --handshakefd for controller cmd fully
by Michal Privoznik 19 Apr '21

The command line argument is called --hanshakefd (check out lxc_controller.c:main()). But the command line builder puts only --handshake.

[PATCH] cmdDomBlkError: Fix crash when initial call to virDomainGetDiskErrors fails
by Peter Krempa 19 Apr '21

19 Apr '21

virDomainGetDiskErrors uses the weird semantics where we make the caller query for the number of elements and then pass pre-allocated structure. The cleanup section errorneously used the 'count' variable to free the allocated elements for the API but 'count' can be '-1' in cases when the API returns failure, thus attempting to free beyond the end of the array.

by Jiri Denemark 19 Apr '21

19 Apr '21

We are getting close to the next release of libvirt. To aim for the release on May 03 I suggest entering the freeze on Tuesday Apr 27 and tagging RC2 on Thursday Apr 29 in the afternoon. I hope this works for everyone. Jirka
