** Description changed: + [Impact] + Degraded performance during network and disk activity in a kvm guest. + + [Test case] + Try booting a vm and do some disk/net activity with and without this driver. + + [Regression potential] + In case of regressions, it will just hit people using kvm on 32bit armhf hardware (the lpae variant in particular): we already had this driver on in the past, it's on by default on every arch, it's widely used and upstream is very active - i say it's a low potential regression. + + -- Hi, The current armmp (linux-image-3.16.0-26-generic_3.16.0-26.34_armhf.deb) could have virtio-mmio enabled for faster vm guests. Currenlty it seems to have: CONFIG_NET_9P_VIRTIO=m CONFIG_VIRTIO_BLK=y CONFIG_SCSI_VIRTIO=m CONFIG_VIRTIO_NET=y CONFIG_CAIF_VIRTIO=m CONFIG_VIRTIO_CONSOLE=y CONFIG_HW_RANDOM_VIRTIO=m CONFIG_VIRTIO=y CONFIG_VIRTIO_PCI=y # CONFIG_VIRTIO_BALLOON is not set # CONFIG_VIRTIO_MMIO is not set Now using virtio net and block is not possible, and you have to revert to emulated devices.
