Indeed, there is this problem wiht the virtio driver which creates this , sometimes huge bottleneck for machines tat do a fair amount of traffic. Other than using DPDK OVS I would love to heard an alternative or a fix for it. Currently being hit by this issue with no solution.
As you mention for a lab is fine but would be lovely to have a pretty redundant scenario like this in production.
